The vibration isolator contains casing with flange with two cone resilient bushings out of the wire material "Metal rubber"; clamping sleeve with hole for securing of the vibration-isolated object to the vibration isolator; cone support installed on the clamping sleeve; base on which casing is installed. The radial cross-section of bushings is hexagon with sides, antisymmetric relatively to its main diagonal, and rounded peaks.

The invention relates to a vibration-insulating-metal devices, medium and large capacity, capable of working in a hostile environment, in vacuum, in terms of radiation and elevated temperature (up to 450°C).

Known vibration absorber of high capacity Ganzmetalldampfer V 318 mit Zwischenflansch (Metal damper with an intermediate flange) of the German firm STOP the DEMOLITION, comprising a housing with a flange, the upper part of which is made conical supports, two progesterone element (UGE), made in the form of conical sleeves, made of wire material and installed on the conical bearing housing from both sides, the clamping sleeve with a tapered flange, on which rests the lower UGE, with a Central threaded hole for mounting vibroisolating object to the vibration damper, tapered bearing, mounted on the clamping sleeve all the way into her shoulder and fixed retaining ring housed in an annular groove of the coupling sleeve, the base is installed on the housing, attached to it by screws and elastic washers, and UGE of insulator created: radial preload on the centering collar of the housing, the clamping sleeve and the conical bearing and the axial tension on the supporting conical surfaces of these parts.

Also known vibration absorber (see Kotov, A. S. Calculation providentiae the characteristics of the vibration isolators of the Mr material, abstract dissertatsii on competition of a scientific degree of candidate of technical Sciences. - Samara - 2007), comprising a housing, two tapered elastic sleeve of wire nonwoven Mr ("- Metal"), the cover, the Central sleeve, the clamping shoulder screw and fastener - washer, slotted nuts and cotter pins. On the housing, the cover and the center hub is made small concentric flange, which are centered bushings from Mr and creates a radial interference fit. Axially clamped in the sleeve of the Mr is created by twisting the lower slotted nut (if the axis of insulator vertical) to lock the cover to the flange of the clamping screw and the end of the Central sleeve in the lid, and in this position the nut splinters. The body of the insulator has a flange, to which the vibration absorber is attached to the base. Vibrotherapy object is placed on the cover and secured with a washer, a second slotted nut and cotter pin.

This vibration absorber from the insulator firm STOP the DEMOLITION is fundamentally no different. UGE both vibration isolators are impacted in the same way.

These isolators can be used for spatial loading in all six degrees of freedom. Their UGE work in duplex upregulating stop under cyclic loading in compression in the direction of the vertical axis of the insulator and the shift in the simplex upregulating stop in radial directions. the number of their positive qualities should be attributed to their relatively small dimensions and weight, the simplicity of the design and technology of their production.

Vibration absorber firm STOP the DEMOLITION of the technical nature of most similar to that proposed and adopted for the prototype.

However, these insulators have a number of serious shortcomings.

To provide a large capacity of these vibration isolators their UGE made of a wire material of high density, for example, with γ=0.25-0.3 g/cm3. To obtain products from a wire material with such a high density and a given size in their free state (after removing them from the mold) have to apply for such tonnage, which are plastic implementation of coils of wire material in the area of their contact with each other. Moreover, the stage of compression, which results in the introduction of plastic coils, is essential in the manufacture of these products (see the book Lazutkin, Century Dynamics vibration protection systems with structural damping and development of vibration isolators wire material MP.// Samara state University of railway engineering. - Samara - 2010. - 292 pages).

Plastic embedding of turns of the wire material into each other reduces the fatigue strength UGE and resource exploitation of these vibration isolators.

The prototype and similar, you cannot perform a large radial preload UGE on entryuuid the shoulder. Large radial preload these vibration isolators are difficult to perform because, when this occurs the "inflow" of wire material on the end face of the centering flange and an abrupt increase of the friction force turns UGE wall of the centering shoulder. In the UGE on the heights, located inside the shoulder, partly as if "sticking" inside the shoulder, and this significantly affects UFH vibration isolators and can lead to rapid destruction of their UGE.

UGE analog made of wire material Mr (see and.with. 183174 the USSR. A method of manufacturing a non-woven material Mr of metal wires/ A. M. Soifer, B. N. Buzicky, C. A. Pershin. - Publ. 1966, bull. No. 13).

Material Mr bad tensile and torsional and lateral vibrations of the object in places UGE, where they come into contact with the centering shoulder, you may experience tensile stresses leading to local rupture of the material of the sleeves.

In the literature (see the description of insulator of high capacity Ganzmetalldampfer V 318 mit Zwischenflansch German firm STOP the DEMOLITION and see Kotov, A. S. Calculation provedeniya characteristics of vibration isolators of Mr material, abstract dissertatsii on competition of a scientific degree of candidate of technical Sciences. - Samara - 2007), which describes the design of the prototype and similar, not lit conditions, which must execute the ü when creating a workable, with possibly the best UFH, heavily loaded of insulator with progesterone elements made of wire material, and sealed their physical meaning (see below).

Note that in the proposed design of insulator these conditions are met and claimed as a distinctive feature of the proposed design.

When the angle at the vertex of the cone UGE (conical sleeves of wire material) and the elevation of the centering shoulder of the prototype and analogue with significant radial dynamic loads will be residual radial deformation, which will be to grow rapidly with time. This is because the conical sleeve (UGE) these vibration isolators are made unidirectional by pressing the workpiece along the vertical axis of the sleeve. Therefore, the angles of inclination to the axis of the sleeve planes of the main mass of coils inside its volume differ little from the direct and the proportion of shear deformation in the radial deformation of the tapered collet is prevalent, and products made of a wire material made of unidirectional pressing, quickly gaining permanent deformation until invalid when the shear strain than the strain compression in this direction.

Note that the product of the wire material work best in compression in the direction of pressing.

the prototype and similar upper UGE much more loaded, than the bottom, since the loading of insulator weight of the object he zagrujaetsa by the same process that he was drunk at the creation of axial tension, and the bottom UGE when it is unloaded and the result is less loaded condition, even compared to his state after a axial tension.

As a result, when the dynamic loading of insulator loading top UGE is described by the hysteresis loop are either partly or entirely lying on the "tails" of its field progesterone loops, which greatly impairs UFH of insulator, increases congestion and resonance frequency vibroisolating object, which in turn leads to "shrink" material UGE and reduce their axial tension. Moreover, as developments increase "shrinkage and residual radial deformation increases the density of the material UGE. In addition, due to the wear increases the friction on the contact surfaces of coils.

All of this will lead to the fact that the working hysteresis loop of the vibration damper further will be "pushed out" to "tail" of the field, will increase srednetehnicheskoe the rigidity of the insulator, and hence the resonant frequency of the dynamic system "object - vibration isolators", the scattering coefficient of the insulator will be reduced and, consequently, to boutviseth dynamic overload, acting on the object in the resonance zone. Moreover, the intensity increases the adverse impact of these factors will continuously increase as the lamp. Naturally, the intensity increases these adverse factors strongly depends on the successful choice of the initial design parameters of the vibration damper.

The disadvantages of the prototype and similar should also be attributed to the absence of elastic compensating for the loss of axial tension in the mean time, due to the rigid fastening parts (until it stops), creating axial tension in UGE. As a result, when the reduction of axial tension due to "shrinkage" UGE first may appear in axial offset vibroisolating object range in which the vibration absorber will operate in simplex upregulating stops, and, therefore, will deteriorate oprahfication characteristics (UFH) vibration isolators. The progressive reduction of the axial tension in the mean time can lead to a complete failure of these vibration isolators.

Therefore, the task of development of insulator high capacity (with the same range of capacities, as in the prototype), but without fully or to a great extent the disadvantages of the prototype and similar, with vibration absorber compared to the prototype and similar to them, the l would be the best UFH, and, therefore, the dynamic system vibrotherapy object - vibration isolators" would have a lower resonant frequency and the object was affected less dynamic overload in the resonance zones, and in the above-resonance, and offer vibration absorber would be more life than the prototype.

The problem is solved in that a vibration absorber, WBGU heavy vehicles, comprising a housing with a flange placed therein with radial and axial tension two tapered elastic sleeve of the wire material MP, made unidirectional by pressing in the direction of the axis of the sleeve, and mounted on the conical bearing housing from both sides, coupling sleeve, with a Central threaded hole for mounting vibroisolating object to the vibration damper, tapered bearing mounted on the clamping sleeve, the base is installed on the housing, attached to it by screws and elastic washers, characterized in that that tapered elastic sleeve is made of a material Mr low density, the value of which is determined from the condition of the absence of introduction of plastic into each other of coils of material in the manufacture of bushings pressed, or a small amount of such implementation, for example, with density γ=0,1÷0.15 g/cm3and the required density of the material of the elastic liners is for γ=0,2÷0,3 g/cm 3created by radial and axial tightness created in the sleeve during Assembly of insulator proposed method, the dimensions of the elastic bushings defined in such a way that, under the simultaneous action attributable to the vibration absorber of the weight of the object, and the maximum operation force due to periodic dynamic overloading, dynamic loading processes of insulator would have been on the "tails" of his field progesterone loops, or hysteresis loop, the bounding box hinges valid when the amplitude of the periodic load would have a small "tails" that are valid reducing UFH of insulator, and when a large shock load it would be permissible loading progesterone elements of insulator on loops with "tails", the radial cross section of the elastic bushing is a hexagon with sides of skew-symmetric about its main diagonal, and rounded peaks, vertical sides of the hexagon are formed cylindrical portions of the inner and outer surfaces of the elastic bushings, which they with radial preload rely on the cylindrical wall of the housing and the cylindrical portion of the coupling sleeve, the inclined sides of the hexagon with a smaller angle to the vertical axis of insulator are abrazos the mi-free tapered surfaces of the sleeves, and sloping sides of the hexagon with a large angle to the vertical axis of insulator are formed tapered portions of the surfaces of the sleeves, which they with axial preload rely on the conical bearing surface of the housing, the bearings and the cover, and the outer diameters of the supporting conical surfaces of these parts a few millimeters larger outer diameters response supporting the conical surfaces of the elastic sleeves, and the height of the cylindrical portions of the surfaces of the elastic bushings in the assembled state is selected such that when the elastic deformation of the bushings in the radial direction of the bulk of the wire material of the bushing is subjected to compressive deformation, the cylindrical wall of the housing acts on both sides of its conical base to the height of the sleeve in a free state, the clamping sleeve is made of the flange, the end of which rests against the conical bearing, and a flange thickness less than the depth of the bore in the conical bearing, in which it is located, the outer diameter of the conical bearing two moves of the insulator in the radial direction smaller than the inner diameter of the cylindrical wall of the casing and the diameter of the inner bore of the case base on two radial stroke larger than the diameter of the smooth cylindrical portion of the clamping sleeve, conical cap worn on the smooth cylindrical hours is ü coupling sleeve and centered on it, and its outer diameter equal to the outer diameter of the conical bearing, and at its outer surface is planar support platform, and a given value of axial preload of the elastic bushings created by tightening all the nuts that screw onto the threaded end of the clamping sleeve, which has one, two or more connected in series elastic washer, the number of which is determined from the condition that the total deformation of the elastic washers must be equal to or slightly larger than the total allowable shrinkage of the elastic bushings and total permissible residual axial tension, in which the vibration absorber is still working, the value created in the elastic bushings axial preload is controlled by the dimension H between the flat end cap, and a flat belt, made on the outer surface of the conical support, and vibrotherapy object is attached to the insulator by means of a screw, screwed into the coupling sleeve, and an elastic washer, and sharp edges of the cylindrical wall and a conical enclosure base, cover, conical bearings, and joints of the casing wall with its base rounded radii, and the support surface of the flange of the case is made centering flange, the internal diameter of which is equal to the inner diameter of the casing wall, and the outer - its outside diameter, and the base is made calcev the I groove, which includes the flange and the base is centered on its outside diameter.

Manufacturer UGE of insulator with a small density γ=0,1÷0.15 g/cm3 and obtaining density, providing the required bearing capacity and UFH of insulator, due to the axial and radial interference fit created during Assembly of the vibration damper, is the original and the new proposal. Its implementation, in our opinion, because of the above reasons can significantly improve the fatigue strength UGE of insulator, allows you to create large radial and axial tightness in UGE (in mm), and, therefore, to provide a vibration damper in duplex upregulating stop at any spatial loading of insulator over the entire period of its operation, to improve its UFH and increase the service life of the insulator. We emphasize that this proposal cannot be implemented in the construction of the prototype and similar.

The absence of the proposed vibration damper centering shoulder in the housing, the bearings and the cover, which in the prototype centered elastic sleeve and created in them the tightness, the presence of rounding sharp edges at the wall and conical enclosure base, support and cover in contact with the material of the elastic sleeves, and rounding sharp edges themselves elastic sleeves drop is no opportunity to "drafts" of the material of the sleeves and the emergence of local discontinuities in the material.

Compared with the prototype strain due to axial and radial tightness, more evenly distributed on all boundary of the contact surfaces of the bushings, which significantly improves UFH offer of insulator.

The required parameters of the proposed vibration damper are determined by calculation or experimentally, taking into account the fact that when the elastic bushings duplex upregulating stops, when the axial loading of insulator constant force G and periodic cyclic force with a maximum amplitude of the specified technical task, vibration absorber must be loaded on the hysteresis loop without "tails", while the deformation of the bushings under the action of a constant force will be much more deformation of these bushings under the action of only one constant force as the center of the hysteresis loop under the action of a constant force will shift point with the ordinate G process with a stiffness equal to the lower stiffness of the stiffness of the processes limiting the loop.

And although this condition will increase the outer diameter of the elastic bushings (approximately 10-15%) and, consequently, the overall dimensions of the insulator in the horizontal plane and its weight, a significant improvement UFH of insulator more than cover this deficiency, so as to decrease significantly cut the frequency spec trum system "object - the vibration isolators and dynamic overload at resonance, and hence the service life of the insulator.

Installation of series-connected elastic washers under the round nut eliminates unacceptable weakening of its torque at the time and, therefore, there is no need in its Peresetsky at the time. Note that the larger set of series-connected elastic washers under all nuts, the large tightening force is maintained during the same axial permanent deformation of the sleeves.

The presence of the centering flange with the specified size on the supporting surface of the flange of the body allows you to use the same snap-in to create a radial tightness in the upper and lower elastic sleeve.

The lowest residual strain and its rate of accumulation in the mean time ceteris paribus get products from wire material MP running on cyclic compression. The time of accumulation of permanent deformation to an invalid size is determined by the resource of these products.

The percentage deformation at loading of insulator in the radial direction, when the UGE of insulator simultaneously experiencing deformation of the compression and shear, at the same radial deformation UGE in the proposed insulator is substantially higher than that of the prototype and similar that put the considerable impact on the life of the proposed insulator. This percentage may be increased.

Therefore, to increase resource insulator serves vibration absorber, WBGU large payload, wherein the elastic sleeve is made of successive pressing of the workpiece in the radial and axial directions, and the degree of deformation of the workpiece at each of these operations phases pressing chosen so that the plane of coils of the main mass of coils in the volume of the sleeve is inclined to the vertical axis of insulator angles φ lying in the range of 45°≤φ≤α, where α is the angle equal to half the cone angle of the elastic sleeve.

In this case, the portion of the shear deformation of the elastic bushings at their radial dynamic loading are further reduced and decreases the slew rate of the residual deformation of the sleeves, thereby increasing the service life of the insulator.

In addition, to simplify the design of the insulator and the technology features of the vibration absorber WBGU heavy vehicles, characterized in that its elastic sleeves are made with a flat horizontal support surface, and the tilt angles of the planes of the coils to the vertical axis of each sleeve from the main mass of coils of material bushings little different from 45°, and a support, the base and cover are also made with a flat Horiz is stalnye support surfaces.

Design and technology of manufacturing of bearings, housings and covers of insulator simplified due to the simpler geometry of these parts and decrease the dimensions of the insulator.

In order to reduce friction UGE on the inner surface of the cylindrical walls of the casing and the outer surface of the cylindrical part of the coupling sleeve on these surfaces can be applied solid lubricant.

The coefficient of friction of coils of wire material on these surfaces will be reduced significantly and, consequently, the range of allowable radial tightness, at which there is slippage of the wire material UGE on these surfaces can be greatly expanded upward.

The prototype and the analogous process of gradual developments "breakdown" of the surfaces of the holes and the "shrinkage" of the outer surfaces of the elastic bushing in contact with the centering flange. In the elastic sleeve may be out of contact with the shoulder. This will greatly reduce their UFH and faster will result in the loss of their functionality.

Similar processes will occur and the proposed vibration isolators, but with much less intensity due to the fact that the proposed vibration isolators dynamic radial load directly affects large areas and in their UGE with the building significantly greater than that of the prototype, the radial preload in mm.

We offer vibration isolators with elastic sleeves with flat horizontal reference surfaces of these processes will be more intensive than the proposed vibration isolators with tapered sleeves. Therefore, the vibration isolators with elastic sleeves with flat horizontal reference surfaces is recommended to be applied at lower dynamic loads.

The methods of vibration isolators prototype and similar, do not differ from each other. The technical essence they are the closest to the proposed methods of vibration isolators, WBGU large capacity.

Therefore, the method of insulator prototype containing the installation of the elastic conical bushings, made of wire material by pressing in the direction of the axis of the sleeves, the bottom elastic bushings in flange coupling sleeve and the upper elastic sleeve in bearing, radial preload on the centering collar of these items, the installation of these assembled units on the conical base of the case on both sides with a radial interference fit elastic sleeves for centering the flange of the base body, the creation of axial tension in the elastic bushings compress them in the axial direction of the support and the clamping sleeve to lock the supports in the flange coupling sleeve and record these details in this is ulozhenie install it in the groove of the coupling sleeve locking ring, fixed to the flange of the housing base with the screws and elastic washers, taken as a prototype of the proposed methods.

This method is easier to offer, but not suitable for the Assembly of the proposed vibration isolators, WBGU large capacity.

Therefore, the method of Assembly of the vibration isolators WBGU large payload that contains the operations to create radial tension in the elastic bushings wire of Mr material, manufactured by pressing in the direction of the axis of the sleeves, to create axial tension in them and mount the base to the flange of the housing by screws and elastic washers, characterized in that the bearing wear on the clamping sleeve to lock it in flange coupling sleeve, until it stops at the end of the coupling sleeve wrapped around a technological core, the outer diameter of which is equal to the outside diameter of the smooth part of the coupling sleeve, put on the rod and a smooth portion of the coupling sleeve without tightness of the upper elastic sleeve so that she sat on the base of the conical surface, the guide of the hollow cylinder, the inner surface of which consists of an upper cylindrical part with a diameter equal to the outer diameter of the elastic sleeve in its free state, the cone smoothly paired with a cylindrical, with a small cone angle and a smaller diameter equal to the outer diameter is the ETP of the elastic sleeve in the condition its in the assembled insulator, the inner diameter of the casing wall, and the lower cylindrical part with this diameter, mounted on the housing with the alignment on the outer surface of the casing wall, insert elastic sleeve with a support, clamping sleeve and the technological core of the guide cylinder, mounted on a support plug cylindrical portion equal to the diameter of the supports with a length that enables the installation of the elastic sleeve in the body of the insulator, so that the middle cylindrical portion with a diameter equal to the diameter of the hole of the upper part of the cylinder, the plug goes in it when creating radial tension in the elastic sleeve, the axial force applied to the punch, push the elastic sleeve so that she sat on the base of the insulator, and the punch end face of the upper cylindrical part rested in the distance the spacer is installed on the end of the guide cylinder, either directly in the face, remove the plug and spacer spacer and remove the guide cylinder from the frame by turning the housing with built-in details on 180° and install them in a glass of alignment on the outer surface of the casing wall, and similarly create a radial preload in the second elastic sleeve is again mounted on the housing of the guide cylinder centered on the outer diameter of the centering Boo the tick, made on the support surface of the flange of the body, put the second elastic sleeve on the technological core, install the cover and punch until it stops him in the distance the spacer or at the end of the guide cylinder push the second elastic sleeve so that she sat on the base of the case, remove the plug, remote spacer and the guide cylinder, remove the assembled host of the glass and fix it on your desktop so that it was convenient to control the axial tension in the elastic bushings, sbencivu technological rod, mounted on the clamping nut elastic washer or two, or more series-connected elastic washers and create the desired axial tension in the elastic collet tightening all nut or wrench with torque moment or control the amount of torque on the dimension H between the flat end caps and a flat belt, made on the outer surface of the support, release the collected node from the holder and fix it to the base.

If, when creating radial and axial tension in the elastic bushings their free cone unacceptably distorted, the method of Assembly of the insulator WBGU a large capacity that allows the Assembly process to correct both free cone top elastic sleeve and a free cone with the larger the m, the diameter of the bottom of the elastic sleeve.

This method of Assembly of the insulator WBGU large-capacity differs in that after radial tension at the top of the elastic sleeve and rotation of the collected node 180° free the taper hole of the upper elastic bushings fix the plug with conical working part geometry correcting this cone sleeve and the punch is centered on the hole in the base, and the free cones of the outer surface of the elastic bushings correct after creating the axial tension in the elastic bushings arrangements with conical working parts with geometry correcting these cones, and the wall thickness of the punches are made slightly smaller size of the gaps between the support or the cover and the wall of the housing, and the punches are centered on the inner surfaces of the casing wall.

Free cone in the bottom hole of the elastic sleeve is not corrected. So his options in free condition sleeve experimentally pick up so that in the assembled insulator his arguments were valid.

In addition, the method of Assembly of the insulator WBGU heavy vehicles, characterized in that the old technology core sbencivu with the threaded end of the clamping sleeve and in its place install a new technological rod with the same outer diameter, centering on externally is the diameter of the thread of the clamping sleeve, on the case flange with centering on his shoulder mounted intermediate guide cylinder whose inside diameter equal to the inner diameter wall of the body at him with alignment on the belt with an outer diameter equal to the outer diameter of the casing wall, set the guide cylinder, the lower elastic sleeve with cover is pushed by the plunger in the position in which the bottom end of the elastic sleeve coincides with the bottom end of the intermediate guide cylinder, remove the intermediate guide cylinder together with an elastic sleeve mounted on it with a lid and technological rod, and insert this node into the glass so that the bottom of the glass stared at the cover, the punch, which was corrected free the taper hole of the upper sleeve, correct free the taper hole of the lower elastic sleeves, establish intermediate guide cylinder with bottom elastic sleeve, cover and technological rod into position and install spacer spacer intermediate guide cylinder centering on his belt, punch, which pushed the upper sleeve, push the lower elastic sleeve with the cap before landing elastic sleeve on the base and plug the remote spacer, remove the plug, remote spacer and release Ivshina intermediate guide cylinder and technological core.

The advantage of this method is that repairs all available cones elastic sleeves, if necessary.

Advantage of all of the proposed methods is the fact that when creating radial and axial tightness in the elastic bushings occur mainly on the compressive stress and not having a tensile stress to which the wire material MP does not work.

Features vibration absorber, WBGU large carrying capacity (see Fig. 1 and 2), comprising a housing 1 with a flange 2, is placed therein with radial and axial tension two tapered elastic sleeve 3 of the wire material MP, made unidirectional by pressing in the direction of the axis of the sleeve, and mounted on a conical base 4 of the housing 1 on both sides, the clamping sleeve 5, with a Central threaded hole 6 for fastening vibroisolating object 7 to the insulator, the conical bearing 8 is mounted on the coupling sleeve 5, the cover 9, round nut 10, the elastic washer (or elastic washer) 11, the base 12 is installed on the housing 1, attached to it by screws 13 and the elastic washers 14.

Tapered elastic sleeve 3 (see Fig. 1) made of Mr material low density, the value of which is determined from the condition of the absence of introduction of plastic into each other of coils of material in the manufacture of bushings pressed, or a small amount of such implementation, for example, with density γ=0,1÷0.15 g/cm3and the required density of the material of the elastic bushings γ=0,2÷0,3 g/cm3created by radial and axial tightness created in the sleeve 3 during Assembly of insulator proposed method (see below). The dimensions of the elastic bushings 3 are determined so that when the simultaneous action attributable to the vibration absorber force G weight of the object and the valid operation forces training is a result of periodic dynamic overload, dynamic loading processes of insulator would have been on the "tails" of 15 field progesterone loops (see Fig. 3), or hysteresis loop, the bounding box hinges valid when the amplitude of the periodic load would have a small "tails" that are valid reducing UFH of insulator, and when a large shock load it would be permissible loading progesterone elements of insulator on loops with "tails" 15.

The radial cross section of the elastic bushings 3 (see Fig. 1) is a hexagon with sides of skew-symmetric about its main diagonal, and rounded tops. Vertical sides of the hexagon are formed cylindrical portions of the inner and outer surfaces of the elastic bushing 3, which they with radial preload rely on the cylindrical wall 16 of the housing 1 and the cylindrical part 17 of the clamping sleeve 5, the sloping sides of the hexagon with a smaller angle to the vertical axis of insulator are formed of free tapered surfaces of the collet and inclined sides of the hexagon with a large angle to the vertical axis of insulator are formed tapered portions of the surfaces of the sleeves, which they with axial preload rely on the conical bearing surface of the housing 1, the supports 8 and the cover 9. The outer diameter of the conical support surfaces of these parts a few millimeters larger outer diameters response supporting the conical surfaces of the elastic bushings 3, and the height of the cylindrical portions of the surfaces of the elastic bushings in the assembled state is selected such that when the elastic deformation of the bushings in the radial direction of the bulk of the wire material of the bushing is subjected to compressive deformation.

Cylindrical wall 16 of the housing 1 acts on both sides of its conical base 4 at the height of the sleeve 3 in the free state. On the coupling sleeve 5 is made of the flange 18, the end of which rests against the conical bearing 8, and the thickness of the flange 18 is less than the depth of the bore 19 in the conical bearing 8. So vibrotherapy object 7 is based on prop 8. The outer diameter of the conical bearing 8 on two turns of the insulator in the radial direction smaller than the inner diameter of cylindrical wall 16 of the housing 1, and the diameter of the inner bore of the base 4 of the housing 1 at two radial stroke larger than the diameter of the smooth cylindrical part 17 of the clamping sleeve 5. Conical cap 9 mounted on the smooth cylindrical part 17 of the clamping sleeve 5 and is centered on it, and its outer diameter equal to the outer diameter of the conical bearing 8.

The desired axial preload of the elastic bushings 3 created by tightening all the nuts 11, screw on the threaded end of the coupling sleeve 5, which has one, two or more connected in series elastic washer 10, the number of which is determined from the condition, is the total deformation of the elastic washers must be equal to or slightly larger than the total allowable shrinkage of the elastic bushings 3 and total permissible residual axial tension, in which the vibration absorber is still working.

The value created in the elastic bushings 3 axial preload is controlled by the dimension H (see Fig. 1) between the flat end face 20 of the cover 9 and the flat belt 21, is made on the outer surface of the conical bearing 8.

Vibrotherapy object 7 is attached to the insulator by means of a screw 22 screwed into the clamping sleeve, and the elastic washer 23.

Sharp edges of the cylindrical wall 16 and a conical base 4 of the housing 1, the cover 9, the conical bearing 8 and the junction of the casing wall with its base rounded radii.

On the support surface of the flange 2 of the housing 1 is made centering flange 24 whose inside diameter equal to the inner diameter of the wall 16 of the housing 1 and the outer - its outside diameter, and base 12 is made annular groove, which includes the flange and the base 12 is centered on its outside diameter.

If the coefficient of friction between the support surface of the support 8 and the upper elastic sleeve 3 is too large, between them install steel conical spacer (not shown), either on this reference surface 8 is applied solid lubricant.

It is also proposed vibration absorber, WBGU large payload (not shown), wherein the elastic sleeve is made of successive pressing of the workpiece in radiation is lnyh and axial directions, while the degree of deformation of the workpiece at each of these operations - phase extrusion, are selected in such a way that the plane of coils of the main mass of coils in the volume of the sleeve is inclined to the vertical axis of insulator angles φ lying in the range of 45°≤φ≤α, where α is the angle equal to half the cone angle of the elastic sleeve.

In addition, it is proposed vibration absorber, WBGU large carrying capacity (see Fig. 4), characterized in that its elastic sleeve 25 is made with a flat horizontal support surface, and the tilt angles of the planes of the coils to the vertical axis of each sleeve from the main mass of coils of material bushings little different from 45°. Bearing 26, the base 27 of the housing 28 and the cover 29 are also made with a flat horizontal support surface.

Guide hollow cylinder 39, the inner surface of which consists of an upper cylindrical part 40 with the bore diameter equal to the outer diameter of the elastic sleeve 3 in its free state, the conical portion 41, fluidly coupled to the cylindrical portion 40, with a small cone angle and a smaller diameter equal to the inner diameter of the wall 16 of the housing 1, and the lower cylindrical part 42 with this diameter, mounted on the housing 1 with the alignment on the outside of the Ergneti wall 16 of the housing. Insert the elastic sleeve 3 with the support 8, the clamping sleeve 5 and technological rod 38 in the guide cylinder 39. Mounted on the support 8, the punch 43 to the cylindrical portion 44, is equal to the outside diameter of the bearing, with a length that enables the installation of the elastic sleeve 3 in the housing 1 of the insulator, so that the average of the cylindrical part 45 with a diameter equal to the diameter of the hole of the upper part of the cylinder 39, the plug 43 is sent to it when creating radial tension in the elastic sleeve 3. Axial force applied to the punch 43, pushing the elastic sleeve 3 so that it sat on the base 4 of the housing 1 of the insulator and the plug 43 the upper end of the cylindrical part 46 bear against spacer spacer 47, mounted on the end of the guide cylinder 39 or directly in the face.

Therefore, when creating the radial preload (in mm) required to ensure the work UGE duplex upregulating it stops at loading of insulator permissible radial loads, does not create excessive friction UGE on the wall of the housing and the smooth cylindrical portion of the coupling sleeves prevent slippage of the material UGE regarding these components under cyclic loading of insulator in the direction of its vertical axis.

When creating axial preload radial tension in the UGE will increase mainly due to the availability of cones in UGE. But this increase is small due to the small angles NWO is adnych cones and, if necessary, the amount of radial preload created the first can be selected taking into account the increase in the creation of axial tension.

SUBSTANCE: vibration absorber comprises two tapered resilient bushes from wire non-woven web of rubber-metal material. Small concentric collars are made on the casing, cap and flange of a central bush and are used to align the tapered bushes and provide for radial preloading. Axial preloading in the tapered bushes is created by tightening the lower slotted nut up to the stop of the cap against the coupler screw collar and of the face of the central bush against the cap. The vibration absorber casing is fitted by a flange by which the vibration absorber is connected to a base plate. A unit with its vibration to be absorbed is mounted on the cap and fixed by a washer, the second slotted nut and a split pin. When free, the outer diameter of the tapered bushes is equal to the inner diameter of pilot collars of the casing, cap and flange of the central bush. Diameter of the centre opening of the tapered bushes is equal to the outer diameter of the inner pilot collars of the cap and flange of the central bush. When free, the cone angle of the tapered bushes is determined according to the formula. The height of pilot collars is chosen so that alignment of bushes as per the collars is provided immediately before the creation of preloads on contact surfaces of tapered bushes when they are free.

EFFECT: simplification of assembly procedure for a vibration absorber without its performance characteristics being deteriorated.
