(57) Abstract:

The invention relates to lubrication systems, in particular hybrid lubrication system with auxiliary pumping oil for use in the Assembly of the transmission. Hybrid engine lubricant applied on the main gear and includes the oil-sump, made at the same time with the body of the main gearbox. Variable oil level in maslootzhimnye is a specified distance between the surface of the oil and the bottom of the housing. The radial protrusion located between the cylindrical portion and a narrowed section of the side wall of the housing, forms in conjunction with the nozzle passage channel. The passage directs peripheral flow of oil accumulated on the bottom of the housing, mbloomstein with a higher oil level. End surface of the annular plate satellitedata rotating relative to the side wall of the housing, exerts a viscous oil pumping effect, indicating to the oil ring and the centrifugal speed causes the oil to move through the channels through to allow the channel to a higher level. 8 C.p. f-crystals, 8 ill.

The invention relates to lubrication systems and, in castnia which enables viscous discharge of oil from the bottom region of the main gear in mbloomstein.

The lubrication system is a vital functional subsystem, which is coupled with the transmission. Effective work gear sets and bearings require lubrication. The role of lubrication is to reduce friction in the nodes of the transmission, the heat from the friction nodes and the removal of metallic wear products. Typical variants lubrication system transmission helicopters is shown schematically in Fig. 1A, 1B.

In Fig. 1A schematically shows an engine lubrication 110 with built-in maslootdelenija type used on helicopters BLACK HAWKR(name of BLACK HAWK is a registered trademark of the division of Sikorsky aircraft company United technologies Corporation). In the system 110 lubrication oil is supplied to the left and right input modules and modules of the drive units 102, 103 (the diagram shows only one input module 102 and the drive module units 103). The composition of the input modules 102, transmitting torque from the power plant to the main gear 104 that is fixed to the motor shafts, the input gears, clutch, output shafts and their bearings and couplings. The main gear 104 has an upper portion 104U, which placed second gear stage with their the a priori level, transmitting torque to the shaft of the main rotor of the helicopter.

In the lubrication system 110 with built-in maslootdelenija are: mbloomstein 112, located in the bottom region of the lower part. 104L main gearbox 104, several auxiliary waste oil channels 114 reporting between the top and bottom of the main gear 104U, 104L, as well as several major waste oil channels 116, indicating the lower portion 104L of the main gearbox 104 with maslootdelenija 112.

In addition, the lubrication system 110 with built-in maslootdelenija includes right and left pumps 118, each pump 118 has a suction stage 118A and forcing step 118B (the diagram shows the stages 118A, 118B only one oil pump 118), pipelines 120 connecting each of the input modules 102 and modules of the drive units 103 with maslootdelenija 112, pipelines 122 connecting mbloomstein 112 with the heat sink 124 (designed to cool oil, pipelines 126 connecting the radiator 124 oil manifold 128, and the pipes 130, 132, connecting the oil collector 128 with the upper part 104U main gearbox 104 and the right and left input modules 102. The pipes 130, 132 end oil Fortuna in the input modules 102, the right and left drive modules units 103, and the main gear 104.

The oil contained in maslootzhimnye 112, served right and left pumping stages 118B oil pumps 118 pipeline 122 in the heat sink 124, where it is cooled. The cooled oil is supplied through pipelines 126 in the oil reservoir 128 and pipeline 130, 132 on the nozzle, providing lubrication of the rubbing surfaces, as described in the previous paragraph. The right and left pumping stage 118A oil pumps 118 are used for oil return from left and right input modules 102 and modules of the drive units 103 through pipelines 120 in mbloomstein 112.

In the case of the main gearbox 104 oil flows into mbloomstein 112 by gravity. Oil from the upper portion 104U flows into the lower portion 104L of the main gearbox 104 for supporting the waste channel 114, and from there to mbloomstein 112 on the main waste oil channels 116. Likewise flows into mbloomstein 112 on the main waste oil channels 116 and the oil spray in the lower portion 104L of the main gearbox.

In Fig. 1B schematically shows the lubrication system 111 with the court maslootdelenija. The design of this lubrication system 111 generally similar design to the spines. Mbloomstein 113 in the lubrication system 111 with the court maslootdelenija is usually not within the lower portion 104L of the main gearbox 104, and taken out from the main gearbox, which allows to optimize the design maslootdelenija 113 so as to make it less susceptible to changes in the spatial position of the helicopter in flight. Instead of an oil pump 118, available in the lubrication system 110 with built-in maslootdelenija, in the lubrication system 111 with the court maslootdelenija installed two oil pump 119, each of which has a pumping speed 119A, 119B and delivery stage 119C. An extraction step 119A are designed for pumping oil from the left and right input modules 102 and modules of the drive units 103 through pipelines 120 in mbloomstein 113. An extraction step 119B are designed for pumping oil accumulating in the bottom region of the lower portion 104L of the main gear 104 through the passage 117 through pipelines 121 in mbloomstein 113. The operation of the pumping stages 119C lubrication system 111 with the court maslootdelenija similar intake levels 118B lubrication system 110 with built-in maslootdelenija.

Both types of lubrication systems 110, 111 with built-in maslootdelenija and with dignity lubrication system 110 with built-in maslootdelenija is its design provides a gravity oil from the main gear 104 in mbloomstein 112, eliminating the need for additional pumping stages 119 and accordingly piping 121, typical lubrication system 111 with the court maslootdelenija. In the lubrication system 111 with the court maslootdelenija additional equipment significantly increases the incremental weight system. In addition, installation of additional equipment decreases the reliability of the entire lubrication system 111 with the court maslootdelenija.

On the other hand, placing maslootdelenija 112 lubrication system 110 within the main gearbox makes the lubrication system 110 is quite sensitive to changes in the spatial position of the helicopter in flight, which can cause sharp fluctuations in AC oil level in maslootzhimnye 112. At any time during the operation of the lubrication system 110 transmission in maslootzhimnye is about 30-50% of the total volume of oil and the remaining 50-70% of oil volume allocated to the other elements of the lubrication system. For normal operation of the pumps 118 requires that the height of the oil column (i.e., the distance between the passage of the pump 118 and a variable level of oil in maslootzhimnye 112) activate under maslootdelenija 112, spatial evolution of the helicopter in flight can cause aperiodic oscillation of AC oil level, leading to reduction of the oil column at the entrance to the pump below the minimum, which, in turn, leads to the ingestion of air pump that violates the mode of operation and, accordingly, the action of the entire subsystem. To compensate for changes in the spatial position of the design subsystem 110 lubrication with integrated maslootdelenija can be recycled under the capacity of the excessive amount of oil, which allows to lower the sensitivity of the lubrication system to the adverse effects of changes in the spatial position of the helicopter. This approach, however, carries with it additional costs and increase the weight of the system, caused by excess oil, as well as increased capacity maslootdelenija, i.e. its height.

The lack of engine lubrication 110 with built-in maslootdelenija is a large separation of its elements in height. Mbloomstein 112 and the pumps 118 in the design of this subsystem 110 lubrication with integrated maslootdelenija can be below the level of the ceiling of the cabin, which reduces its volume.

In the international application WO-A-88/00665 opisanku gear wheel (54), consisting of parts of the body (54B, 54C) forming a camera gears (63, 65) the corresponding forms, which are the elements of the gear and a few cavities collect oil(56, 58, 60, 62), made in parts of the body. Inside of the housing parts (54B, 54C) also performed channels(64, 66, 68, 70), telling between a camera gears (63, 65) the appropriate form and the cavity of the oil collecting(56, 58, 60, 62). Channels (64, 66, 68, 70) are located at the periphery of the cameras gears (63, 65) the appropriate form and is directed tangentially relative to the corresponding elements of the gearing. Channels (64, 66, 68, 70) are tapered profile, which not only prevents the reverse flow of oil in camera gear wheels (63, 65) the appropriate form, but also creates a positive pressure gradient moving through the channels of the flow of oil.

The centrifugal force produced by the rotation of the gear elements in the cells gears (63, 65) the appropriate form, results in the movement of the oil, causing it to flow through the appropriate channels (64, 66, 68, 70) in the corresponding cavity of the liquid collection(56, 62, 58, 60). The oral fluid collection (56, 62, 58, 60) are connected with each other through channels (76, 78, 80a, 82a, 80b, 82b) to prevent the elements of the gearing, flows through the channels (76, 78, 80a, 82a, 80b, 82b) of the cavities of the liquid collection (56, 62, 58) into the cavity of the collection fluid (60). The pump (100) pumps out the oil fed into the cavity fluid collection (60) for distillation through a box of gears.

There is a need for a lubrication system, which would combine the positive qualities of lubrication systems with built-in maslootdelenija and lubrication systems made by maslootdelenija. In particular, in such a system, lubrication mbloomstein were to reduce the spacing elements of the system height, as in the lubrication system with the court maslootdelenija. Such a lubrication system should be relatively stable to changes in the spatial position and should not take the useful volume of the cabin of the helicopter. In this case, the lubrication system should (which is typical lubrication system with integrated maslootdelenija) to have a minimum number of stages pumping and grease that would determine the minimum system weight and increased reliability of the system as a whole.

The present invention was the creation of hybrid lubrication system with auxiliary pumping oil for the main gear transmission whose design is optimized by this integration with the CA gearbox in mbloomstein.

The invention is a hybrid engine lubrication Autonomous pumping oil, in which the construction of the lower part of the main gearbox changed so that the housing is jointly hosting the planetary gear stage has on the oil collecting on the bottom of the housing, forcing the action, informing him about the ring and the centrifugal speed, which contributes to the flow of oil from the bottom of the gear case in mbloomstein.

According to the invention in a hybrid subsystem lubrication Autonomous pumping oil mbloomstein made as one piece with the lower part of the housing, which makes the oil in maslootzhimnye quite resistant to changes in the spatial position of the system, and a variable level of oil in maslootzhimnye is located at a predetermined height relative to the bottom of the housing.

In self-cleaning hybrid engine lubricant according to the invention the amount of oil in maslootzhimnye less than the amount of oil in the lubrication system with integrated maslootdelenija, which reduces the total weight of the lubrication system.

These and other features according to the invention are achieved in a self-cleaning hybrid engine lubrication (with independent pumping oil) for main is part formed by a bottom wall and side wall. Hybrid lubrication system with auxiliary pumping oil includes mbloomstein, made of one piece with the bottom part of the main gearbox. In maslootzhimnye is oil, the surface of which forms a variable level, and mbloomstein is located so that this variable oil level at a predetermined height from maslosborny pump lubrication system.

The design of the side wall of the lower shell main gearbox changed so that it has a cylindrical section, characterized by a first predetermined radius, the transition area adjacent to the aforementioned cylindrical section, and the narrowed area, characterized by a second predetermined radius. The first specified radius exceeds the second predetermined radius of this magnitude that characterizes radially directed protrusion located between the cylindrical and narrow areas. In place of the protrusion is located between the cylindrical and narrow plots, made the passage nozzle channel, the inner and outer walls which are oriented at a tangent respectively to the thin plastic and cylindrical portions of the side wall. In the design of hybrid lubrication system with AV. From the input end of the nozzle channel is the passage, and the outlet end to allow the channel displayed in mbloomstein thus, referred to the output end of the above AC oil level in maslootzhimnye.

The planetary system of gears, located in the lower part of the main gear includes an annular plate satellitedata, the end surface of which has a specified radius. During operation of the planetary system of gears annular plate satellitedata rotates. End surface of the annular plate satellitedata together with cylindrical and narrow sections of the side wall of a modified construction forms two channels: a primary and narrowed, with a view of the first and second radial gaps. On the annular plate satellitedata installed reflective plate is separated from the bottom of the main gear of the third gap.

The rotation of the reflective plate relative to the bottom wall of the casing main gearbox causes the oil in the movement, i.e., has a viscosity pumping effect. This effect is expressed in the message of the oil ring and the centrifugal speed, resulting Mac satellitedata relative to the side wall of the modified design has a viscous pumping action on the oil, located in the main and Suzanna channels, causing it to move in these channels. Almost all the oil, the current through the main channel, is given in the passage nozzle channel and then through to allow the channel to mbloomstein.

During operation of the planetary gears in the main gearbox housing can be deposited metallic particles - products of wear of the contacting pairs of elements of the gearbox. The first gap (radial) and the third gap (vertical) between the plate satellitedata and the housing main gearbox have dimensions that provide the ability to move these products wear on the third gap and the main channel so that in the end these metal particles appeared in the flow of oil from the housing main gearbox in mbloomstein. In this embodiment, the hybrid lubrication system with auxiliary pumping oil first radial gap and the third vertical clearance of approximately 0,97 see

The second gap has a radial dimension that locks the movement of oil through the narrowed channel, resulting in almost all the oil moving in the main channel is given out through the nozzle passage channel. In the present embodiment, and.

The present invention, its features and advantages in more detail in the following detailed description set forth with reference to the attached drawings, in which:

In the drawings, identical to the Ki with independent pumping oil (GSS) 10, made according to the invention. In the present embodiment, SCA 10 is functionally connected with the bottom part 104L of the main gear 104 of the helicopter and has the same characteristics as the above-mentioned lubrication systems with built-in maslootdelenija and with the court maslootdelenija. In particular, the GSS 10 contains mbloomstein 12, described in more detail below, is located so that a variable level of oil in maslootzhimnye 12 was above the oil level at the bottom of the housing lower portion 104L of the main gearbox 104 (as in the lubrication system with the court maslootdelenija). This placement of maslootdelenija 12 weakens the effects of changes in spatial position on a variable level of oil in maslootzhimnye 12, i.e., similarly to the arrangement of the lubrication system with the court maslootdelenija 111. The oil, after passing through the spray nozzles, channels and drains holes in the main gearbox housing 104 (see, for example, position 114 in Fig. 2, 3), is collected at the bottom of the housing lower portion 104L of the main gearbox 104 (similar to lubrication systems with integrated and made by maslootdelenija). However, as further explained below, the GSS 10 there is no separate suction of the oil pump of predictor 104. Instead, the design of the inner surface of the housing lower portion 104L of the main gearbox 104 is changed so that the interaction of the walls of the shell 104 redesigned and placed it third gear stage provided on the viscous oil pumping effect that moves the oil collecting on the bottom of the casing lower portion 104L of the main gearbox 104, mbloomstein 12. This eliminates the need for additional pumping stage 119B available in the lubrication system with the court maslootdelenija 111, i.e. in the GSS 10, made according to the invention, includes a minimum number of pumps, like the lubrication system 110 with built-in maslootdelenija.

As can be seen in Fig. 2, the GSS contains 10 separate pumping stage 118A for each of the input modules 102 and modules of the drive units 103 (this is true for lubrication systems with integrated maslootdelenija, and with the court maslootdelenija), designed for pumping oil from these modules in mbloomstein and appropriate pumping speed 118B, recirculating oil from maslootdelenija 12 back to the right and left input modules 102, right and left modules drive units 103 and main gearbox. Dstruction and functional performance similar to corresponding elements of the lubrication system with integrated maslootdelenija 110 and with the court maslootdelenija 111, above.

In this embodiment, the GSS 10 partially integrated with the bottom part 104L of the main gear 104 helicopter S-92TMHELIBUSTMdeveloped by the company Sikorsky aircraft S-92 HELIBUS are trademarks division of Sikorsky aircraft company United technologies Corporation). In particular, mbloomstein 12 REG 10 shown in Fig. 3-5 and 7, is made along with the bottom part 104L of the main gear 104 helicopter S-92TMHELIBUSTMand consists of the upper chamber 12UCand lower chambers 12LCseparated by an intermediate wall 121, as shown in particular in Fig. 3 (see also Fig. 7). In Fig. 3 shows the drain 14, through which the oil flows from the housing upper portion 104U main gearbox 104 in mbloomstein 12. When the main gear 104 is installed on the helicopter, mbloomstein 12 is located between the front part of the rectangular cutout in the airframe of the helicopter, in which is installed the main gear 104, and the lower cylindrical portion 104L of the main gearbox 104 (see Fig. 5). AC oil level in maslootzhimnye indicated in Fig. 3 position 16, more than a few inches of the level of the bottom wall of the casing bottom is oven bottom wall approximately 13 cm (this difference in the levels indicated in Fig. 3 by the symbol N).

In accordance with Fig. 3-5 internal construction of the body lower portion 104L of the main gearbox 104 helicopter S-92TMHELIBUSTMpresents a bottom wall 18 and side wall of the modified structure 20. The design of the side wall 20 is changed so that the side wall 20 together with the third gear stage played the role of an Autonomous pump pumping oil from maslootdelenija, pumping the oil accumulated on the bottom 18 of the housing lower portion 104L of the main gearbox 104, mbloomstein 12. As can be seen in Fig. 4, 5, the side wall of the modified structure 20 is made (e.g., molded, is processed by means of metallovedenie) so that almost the whole of its circumference is a cylindrical section 22, characterized by a given radius R22. Thus, the shape of the side wall 20 is almost cylindrical. In addition to the cylindrical section 22 of the side wall 20 has a transition section 24 adjacent to one end of a cylindrical section 22, and the narrowed section 26, characterized by a given radius R26and adjacent to the transition area 24. The analysis of Fig. 4, 5 shows that a given radius R22is greater than the given radius R26, i.e., R22> R26. Radial is th wall redesigned 20, forms a passage 28 of the nozzle channel having approximately rectangular cross-sectional shape, i.e., the inner and outer wall bounding the passage 28 of the nozzle channel is oriented at a tangent respectively to the thin plastic and cylindrical portions 26, 22. The passage 28 of the nozzle channel is intended for the peripheral direction of the flow of oil accumulated on the bottom 18 of the housing main gearbox 104 helicopter S-92TMHELIBUSTMin mbloomstein 12.

In accordance with Fig. 5, 7 REG 10 also includes to allow the channel 60 having an input end as described above maslosborny 28 and an output end 64 (see also Fig. 2). On Solovay channel 60 oil from maslosborny 28 hits mbloomstein 12. The output end of the nozzle 64 of the channel 60 is located in the upper chamber 12UCabove the intermediate wall 12I, separating the upper and lower chambers 12UC, 12LCmaslootdelenija 12, i.e., the output end is located above the variable oil level 16 in maslootzhimnye 12. This arrangement of the output end of the nozzle 64 of the channel 60 does not allow the pressure oil flowing from the upper portion 104U main gearbox 104 in mbloomstein 12, to resist viscosity magnetan the th wall 12I of maslootdelenija 12. Through the hole 72 passes the output end of the nozzle 64 of the channel 60. Even in Fig. 5 shows the outlet 76 through which the pumping speed 118B two pumps 118 communicate with the cavity maslootdelenija 12 and the upper housing 104U gear. In maslootzhimnye detector installed shavings in the oil 78, watching the metal wear products in maslootzhimnye 12. The passage of the pump 75 is located at the bottom of maslootdelenija 12 in the vertical Central plane of the helicopter (line O). With this arrangement, maslosborny 75 vibrations AC oil level 16 on the passage 75, due to the roll of the helicopter, minimum. The value of the variable oil level H for greater accuracy would be measured from the location of maslosborny pump 75, but in this case, the level of maslosborny 75 almost equal to the level of bottom wall 18 of housing of the main gear box 104. The passage 75 of the pump communicates with the detector chips in oil 78 and the outlet of the pump 76 through pipe 77.

In the housing lower portion 104L of the main gearbox 104 is a third gear stage of the transmission of the helicopter. The third gear stage main gear 104 helicopter S-92T is ovcoy satellites, containing leading Central gear wheel 30, the set of N primary satellites 32, driven by a Central gear wheel 30, a set of secondary satellites 34, satellite shaft that serves as a support for a respective one other of the primary and secondary satellites 32, 34, the stationary annular gear wheel 38, consisting in engagement with the secondary satellites 34, and the node satellitedata 40 mounted for rotation together with the satellite shafts 36 and outputs power from the planetary system of gears with multilevel stepped arrangement of the satellites on the shaft of the main rotor of the helicopter. This device is described in more detail in international application PCT/US95/05413 on "Planetary system of gears with multilevel stepped arrangement of satellites for improved transmission of the helicopter. The set of N primary satellites 32 consists of a set of N/2 upper primary satellites 32U and population N/2 lower primary satellites 32L, located on two levels in a stepwise procedure, in which each upper primary satellite 32U overlaps the profiles directly coterminous with the lower primary satellites 32L.

From the point of view of the present invention, the camping part of the site satellitedata 40 and shown in Fig. 3 in General and in Fig. 6 - in more detail. Plate satellitedata 42 has a specified outside diameter D42the control slot for the installation of satellite shafts 36 and the end surface 46. The end surface 46 together with the side wall of the modified structure 20 forms in the lower portion 104L of the main gearbox 104 channels of movement of the oil, as described next. The end surface 46, cooperating with the side wall of the housing of the modified structure 20, a 10 SCAC pumping viscous force, which moves the oil collecting on the bottom 18 of the housing lower portion 104L of the main gearbox 104, mbloomstein 12.

The end surface 46 of the annular plate satellitedata 42 together with the side wall of the modified structure 20 forms a main channel in the first gap 50 defined width or radial extent (see Fig. C). The diameter D42the annular plate satellitedata 42 is made chiefly with regard to design and functional requirements of a planetary system of gears with multilevel stepped arrangement of the satellites. Therefore, for the given width of the first gap 50, is equal to R22- D42/2, changed design bnia the width of the first gap 50 is equal to about 0,97 see

The width of the first gap 50 is selected based on design requirements of the gearbox, which consists in the fact that metal wear products that appear when the third gear stage, which is accommodated in the housing main gearbox 104, for example, due to chipping surfaces of bearings, gear teeth, and so on, were removed by the flow of oil pumped out of the casing main gearbox 104 in mbloomstein 12. Therefore, the width of the first gap 50 should ensure the passage of these products wear in the main channel. The second requirement gearbox, specifying the width of the first gap 50, is that the pumping viscous force of nature, created interactive side wall of the modified structure 20 and the annular plate satellitedata 42, must inform the oil flow rate sufficient to transfer the metal particle - wear products from the bottom of the main gear 104 in mbloomstein 12. For this version of the invention the speed of rotation of the end surface 46 of the annular plate satellitedata 42 is approximately 7.7 m/s Empirically it was found that the width of the first gap 50, approximately equal to 0.97 cm, sufficient to transfer ktorej stage.

The end surface 46 of the annular plate satellitedata 42 together with the narrowed section 26 of the side wall of the modified structure 20 forms a constricted channel in the form of the second gap 52 defined width or radial extent (see Fig. 5). This means that the width of the second gap 52 is equal to R26- D42/2. In this embodiment of the invention the width of the second gap 52 is equal to about 0.08 to see the Width of the narrowed channel, i.e., the size of the second gap 52 is selected based on design requirements of the gearbox, which consists in the fact that almost all the oil, which acts viscous pumping power was taken out of the main gear 104 in the peripheral flow through the passage 28 of the nozzle channel 60. Thus, through the narrowed channel, or the second gap 52, passes the minimum amount of oil. Practically it is provided with a large ratio of the width of the cross sections of the channel maslosborny 28, i.e., R22- D42/2, and contracted channel 52. For this version of the invention, this ratio is approximately equal to 0.89/0,08 11+.

On the annular plate satellitedata 42, as shown in Fig. 3, has the reflective plate 80 so that the plate 80 is separated vertical tzora 54 is determined based on the same design requirements, which have been discussed in relation to the first gap 50. The reflective plate 80 is designed to pass underneath the oil and metal wear products energy of rotation of the plate satellitedata 42, driving them to the action of centrifugal force to the periphery and forming a flow moving in the main channel. In this peripheral flow moves oil with wear products passing through the planetary gear, i.e. located at the upper surface of the reflective plate 80, as well as oil products wear, gathered between the reflective plate 80 and the bottom wall 18 of housing of the main gear box 104. On the bottom surface of the reflective plate 80 can be applied grooves that facilitate dispersal of the oil from under the plate satellitedata 42 to the periphery.

In addition to the centrifugal force by rotating the reflective plate 80 on the metal particles of wear products and oil passing through the planetary gear, they are touched by a viscous pumping power. This power is derived from: (i) the interaction between the lower surface of the rotatable reflective plate 80 with the bottom wall 18 of the main gearbox 104 and (ii) interaction of the end poverty viscous pumping power: (i) dispersing accumulated on the bottom 18 of the housing main gearbox 104 oil to the periphery, in the main channel (or the first gap 50); (ii) removes the oil from the main channel through the passage 28 of the nozzle channel (practical studies have shown that 65% of the resulting oil flow created by the interaction of the rotating reflective plate 80 and the bottom wall 18 of housing of the main gear box 104). Viscous pumping force acts on the fluid located between the fixed element, i.e., bottom wall 18 and side wall of the modified structure 20, and a moving element, i.e., respectively, the reflective plate 80 and plate satellitedata 42. The fluid layer adjacent to the stationary element, it will be almost stationary, while the fluid layer adjacent to the moving element, will move at a speed approaching the speed of a moving element, i.e. the speed of a moving element is transmitted to the bordering layer of fluid by the forces of viscous friction. The symbol R denotes in Fig. 4, 5 direction of rotation of the reflective plate 80 and the annular plate satellitedata 42. Viscous pumping force caused by rotation of the reflective plate 80 and plate satellitedata 42, according to the oil ring and the centrifugal speed t and moves along the main channel, limited lateral wall of the modified structure 20 and plate satellitedata 42.

According to the Bernoulli law, approving the conservation of moments of momentum in the fluid flow, the viscous energy discharge generates a given volumetric flow of oil through the primary channel with the width of the first gap 50. According to the Bernoulli law in the field of maslosborny 28 nozzle channel set volume flow is approximately constant. Since the beginning of the narrowed section 26 of the side walls of the tapered channel comprising the second gap 52, and allow the channel in the form of maslosborny 28 are integral with channel, almost all of the set volume flow generated by the viscous force of the discharge will be discharged through the passage 28 of the nozzle channel. Thus, the pumping power of the viscous nature arising from the interaction of: (i) a bottom wall 18 and the reflective plate 80 and (ii) the side wall of the modified structure 20 and the end surface 46 of the annular plate satellitedata 42, causes the oil to move out of the main gear 104 through the passage 28 and to allow the channel 60. Theory of viscous discharge shows that GSS 10, made according nastojashem, when pumping from the housing lower portion 104L of the main gear 104 in mbloomstein 12. The pumps 118 REG 10 have dimensions that provide the performance of the oil supply in the main gearbox 104, equal to 54.5 l/min Of these 54,5 l/min to about 25 l/min is served either flows by gravity to the bottom 18 of the housing main gearbox 104. Taking into account the above data it becomes obvious that the viscous injection, used in the GSS 10, made according to the present invention is quite effective pumping oil from the bottom 18 of the main gear 104 in mbloomstein 12.

Although GSS 10, made according to the present invention, considered in relation to structural and functional characteristics of the main gearbox of the helicopter S-92TMHELIBUSTMfor professionals it should be clear that describes the GSS does not limit the object of the invention the framework of the considered variants of its implementation.
