The invention relates to the field of General engineering, namely to the means for transmitting motion converting speed based on the mechanism of swing (precancerous) washer, and can be used in drives of machines and mechanisms of the widest destination.

Known converters speed, called and classified in different ways, but based on the same principle gear with swash plate (see SU 1414976, 653458, EN 2145016 and US 3525890; 3640154; 4281566; 4841809; 5562560). The transmitting node such converters contains three segments. One of the links is swinging washer end with a ring gear that is engaged with the Central end a toothed wheel, which is the second component of the transmission. The precession of the washer causes the generator of waves that run at different patents in different ways. Swinging washer associated with the third link mechanism for transmitting rotation between the non-axial shafts.

Some of these drawbacks are eliminated converters speed of nutation or precisionenemy systems torque transmission engagement with the Cam links through rolling elements (US 4715249; 4563915; SU 1427115). In the patent US 4715249 on the outer circumference of the tilting washer attached freely rotatable on the axles of the rollers. The rollers cooperate with periodic Cam elements on turned to swing the puck ends of the two parts. One of the parts connected to the frame, the other with the driven shaft. Part of the rollers is in contact with a fixed part, and the rollers at the opposite side of the tilting washer are in contact with the Cam elements of the driven shaft. In this Converter, compared with the timing of transmitting nodes, the reduced friction between the teeth, but still in simultaneous engagement involves only a few elements that agrimi surfaces, what causes the wear, noise and unwanted reciprocating acceleration.

This disadvantage is eliminated in patents US 4620456 and US 5443428. The transmitting node such converters includes an intermediate speed tilting washer which is provided with at least one Cam surface in the form of a trochoidal raceway, siteplease through the chain of balls with trochoidal path on the second part transmitting node.

In the patent US 4620456 side surface of the tilting washer made in the field, and the raceway is made at the intersection of the side and end surface or end surface of the tilting washer. At the opposite end of the tilting washer in the case of single-stage Converter is made holes, siteplease through the second chain of balls with holes in the third part. The second and third parts are connected with a PTO shaft or housing of the transducer, respectively. For fixing the angular position of the balls relative to each other when passing them simultaneously protrusions or depressions on the mating tracks between the mating surfaces introduced thin-walled cage in the holes which are placed balls.

In dehst asnam number of teeth, mating with hypotrochoidal tracks on Cabinet and output details.

Washer wobbles relative to the center of precession, which is the center of symmetry of the system, and chains of balls are numerouse movement, because their plane is offset from the center of precession. Balls make an oscillating movement in the axial and in the radial direction, that is, when the mechanism is changing the offset angle siteplease parts for high-speed mechanisms leads to vibration, and are caused by problems: noise and wear. In addition, the raceway on EPI - and hypotrochoidal curves is complicated to manufacture. Realizing this, the authors proposed to make all the details of the transmission mechanism of plastic material, on which the raceway complex shape can be produced by stamping. It is obvious that such transfer is not suitable for power mechanisms, and can only be used for instruments, watches and similar products.

In the patent 5443428 described are more difficult to calculate and manufacture of profiled Cam surface in the form of multiple spherical located wavy protrusions and depressions designed to eliminate slippage of the balls. Balls here with the STI, undoubtedly indispensable in applications that require high accuracy, smooth operation, for example in the field of space technology, but because of the high manufacturing cost of little use in power drives for mass application and manufacturing.

Nutation component in the movement of the balls is fixed in the Converter speed patent US 1748907. The Converter contains accommodated in the housing, the transmitting node with the swash plate, means for excitation of the precession of the washer and the shaft. The transmitting node contains two covering one another coaxial parts Cam profiled in azimuth elements on the mating side surfaces. The mating side surfaces of the parts made in the form of a spherical zone. Tilting the washer is on the outside, and a Cam shaped surface is made on the inner side surface in the form of spaced along the azimuth of the hole. The inner part is made with a closed periodically curved along the axis of the raceway on its outer side surface. The holes are the balls that are in constant engagement with the raceway. Chain of balls is located in the Equatorial region of the mating slno the same point symmetry of the transmitting node, and engagement will be carried out at a constant angular offset siteplease details.

Means for initiating swinging movement of the washers is an inclined shaft, one end of which by means of a ball clutch is installed in the center of the cage and the other end eccentrically offset from the axis of rotation and mounted with ball coupling on the shaft rotation. The transmitting node is placed in the housing, and the tilting washer is connected with the housing, gear for preventing rotation of the washer. The shaft is connected with the inner part of the sending node. In this Converter are significant friction losses when the slippage of the balls relative to the holes on swinging the puck.

Known Converter speed in patent EP 0048593, which reduced sliding friction balls. On the concept of the transmitting node of the Converter closest to the offer, so we choose it for the prototype. The transmitting node consists of covering each other's cage and swinging washer with side mating surfaces made on the field. These spherical surfaces in the Equatorial region made periodic raceway. They can be Meridiano sphere. In engagement with both raceways are body rolling - balls. The transmitting node, the input shaft and the PTO is installed in the housing. Input shaft provided with a means for excitation of the precession of the washer. Tilting the washer is connected with the PTO or with the body node, transmitting the rotation of the tilting washer regardless of its swinging motion. Accordingly, the holder of the transmitting node is connected directly with the body or with the PTO. The transmitting node is counterbalanced by weight, the rolling body in the process, only precess at that eliminates vibration and related noise and beats. Engaged at the same time there is a large number of rolling elements, which increases the load capacity of the transmission ceteris paribus.

However, a number of advantages node disappear in the Converter speed due to an unfortunate design decisions of other nodes. The patent describes two mechanisms that cause the precession of the washer. First, it is the bracket on the input shaft, an inclined neck which the bearings planted Cup-shaped swinging puck. The neck is inclined at an angle of about 30 degrees to the axis of the transducer. This system is not symmetric relative to the center of precession, and the eve of the Cam, acting on the end of a swinging washer through the bearing. It also breaks the symmetry of the system, in addition, the load is transferred at the same time not more than half of the balls. As host transmission of rotation in the patent is either the CV joint or the second stage is similar to the transmission. The hinge or the second stage of the transfer performing in the same tilting the washer on the opposite side.

In the prototype presents a variant of the Converter, in which the swinging both covering each other washers. This reduces the angle of each of the washers to the axis of the Converter and improve the working conditions of the node transmitting rotation between the non-axial shafts. The mechanism that causes the precession of washers made in the form of two angled spacers on the opposite slope, unbalanced and very bulky, which limits the speed and increases the size of the device as a whole.

In addition, the prototype, as each of the above converters speed with swash plate has a fixed housing, which in each particular design involves quite specific detail, the transmitting node has an internal volume bounded by the body. The Converter with the property increases the size of the device as a whole.

Thus, the object of the invention is the creation on the basis of the transmitting node with the swash plate is universal, simple and convenient for installation in a variety of machines and mechanisms Converter speed.

The technical result of the invention is that the size of the Converter speed is determined mainly by the dimensions of the transmitting node, and all of the additional mechanisms and components fit into these dimensions while retaining all the advantages of the transmitting node, described in the prototype.

Additional technical result is the expansion of the range of new versions of the two-stage converters.

Another technical effect is to reduce the requirements to the form and precision of the raceways for the two-stage Converter with minimal slippage of the balls.

In addition, some variants of the transducer extend its functionality. For example, variants of the Converter with two swinging washers allow you to create a differential converters speed with two inputs and two outputs.

To achieve the technical result of the transformation is s, means for excitation of the precession of the swing washer, PTO and more link associated with the swash plate by the node transmitting rotation between the non-axial shafts. Lateral mating surfaces of the cage and swinging washer made in the form of a spherical zone in the Equatorial region on which the holder and tilting the washer is made closed wavy curved in the axial direction of the raceway with the chain of balls between them. Unlike the prototype, the means for excitation of precession and the additional element is a casing coaxial with each other and the holder of the transmitting node and all clips are connected to each other by means of bearings. The Converter speed in this design is to provide a compact mechanism of the three clips in the form of bearing. If one of the magazines of the Converter when planting it on the workplace secure in the stationary case, you will get an inverter with one input and one output. If one of the magazines to make an additional input, i.e., to associate it with a rotating shaft, the inverter on the output shaft will have a speed dependent on the speed ratio at its inputs.

Node before the in the prototype, the hinge of equal angular speeds. We also proposed mechanisms crosses, the flexible rods or hinges, or bevel gears.

As in the prototype, the transmission of rotation from swinging washer can perform the second step is similar to the transmission. The second step can be implemented both on the same tilting the washer (coaxial layout steps), and an additional clip (serial arrangement of steps).

In the Converter with a serial arrangement of steps additionally introduced the clip is installed with the possibility of precession relative to its center of symmetry, and on its lateral surface is also made periodic wavy curved raceway. This clip serves as a swash plate of the second stage Converter. To do this, coaxial with it installed ferrule of the second transmitting node with periodic raceway surface facing the tilting of the washer, and the second chain of rolling elements. Swinging washer first and second stage of the Converter associated with the node transmitting rotation between parallel shafts. Means for excitation of the precession of both swinging washers ensures their si on the one swinging the puck in patents US 4620456, 5443428, chains of balls both stages are involved in the precession about a point lying in the plane of the chain of balls, and their motion is not notijoya component. This greatly simplifies requirements for the form and accuracy of the raceways for zero slippage balls.

The node transmitting rotation between parallel shafts can be performed by any of the known schemes. Well suited for these purposes the mechanism with parallel cranks. The most preferable from the viewpoint of reducing the friction loss is the mechanism of parallel cranks with ball coupling, as for example in the patents US 4829851 or US 4643047. The same site can be done in the form of a shaft with which each of the swinging washers connected by a crosspiece. For latest designs developed an original mechanism of excitation of the precession of the washers. His cage with the annular protrusion is located between the two stages of the Converter. The clip is made with two oblique parallel cranks, on which bearings are planted swinging washer. The annular protrusion protrudes outside of the casing of the Converter and its outer crown is made as an element of the worm gear, bevel gear, or F. the ptx2">

Ferrule means for excitation of the precession of the swing washer in any of the above converters can be designed as an oblique crank shaft, which bearing planted swinging puck. This scheme is known for converters with swash plate. To the center of precession of the swing washer coincided with the center of the sphere, the bearing must be seated in an oblique crank with eccentric offset and to achieve precise alignment of these points is difficult. We developed the original design of the means for excitation of precession that most closely fits the concept of building a Converter in the form of a bearing of the gearbox. The clip is relatively swinging washer on the side opposite its periodic raceway. On facing to each other surfaces of the cage and swinging washer made closed annular groove and a protrusion mating with each other so that between the lip and the wall of the groove on one side of the washer and between the opposite side of the protrusion and the opposite wall of the groove at the opposite side of the tilting washer introduced two rolling elements. Unlike the prototype, where the precession becauseeach of time involved all the balls at the same time. The system is completely symmetrical relative to the center of precession and fully balanced weight.

Two-stage Converter can be, as in the prototype, implemented on the same tilting the washer with a coaxial arrangement of steps. On the side of the tilting washer on the opposite side from the periodic raceways of the first stage performed the second periodic raceway. On the side of extra clips, addressed to the second periodic raceway swinging washer also made periodic raceway. Between the raceways extra clips and swinging the puck entered the second chain of rolling elements. In the two-stage coaxial Converter speed to excite precession swinging washer can be used all of the above means, since some of them use a second side surface of the tilting washer, which in this case is occupied by the second transmitting node. For this Converter designed in which the holder means for excitation of precession is formed by two hollow shafts imposed on the bearings between the inner and outer hoops preobrazovatele on both the crank shaft through the bearings. In the second embodiment, the hollow shafts equipped with mechanical Cams interacting with the ends of the tilting washer through the bearings. Two opposite end of the Cam to ensure transmission of the load in both half-periods.

The present invention allows to improve also the option of a Converter, in which both covering each other clips are swinging washers. The Converter speed as the prototype contains a tool to excite precession washers, shaft and the transmitting node with two swinging washers with periodically curved raceways on the lateral mating surfaces and balls between them. With each of the washers mechanisms of transmission of rotation between the non-axial shafts linked introduced additional links, one of which is directly connected with the PTO. Unlike the prototype additional links made in the form of clips, and means for excitation of the precession of the swing washers made in the form of two interconnected coaxial hollow shafts, one of which is located outside the outer swinging washer, and the second is inside the interior swinging washer. In each pair the hollow shaft - swing the puck on their bresenham so, between the ledge and the wall of the groove on one side of the washer and between the opposite side of the protrusion and the opposite wall of the groove at the opposite side of the washer put two rolling elements. Rolling elements in each pair are positioned so that washers have opposite tilt and sway in antiphase, i.e., undergo vibrational motion towards each other.

The same result can be achieved, if addressed to the tilting washers surfaces interconnected hollow shafts to perform angled cranks with the opposite slope, interacting with swinging washers through the bearings.

There is one more variant of the Converter with two swinging washers. It means to excite precession is made in the form of two hollow shafts as described above, but the shafts are not connected with each other. In this case, the Converter has two inputs and additional functionality. In case of equal phase and velocity of precession of the swing washers (i.e., two input velocities) at the output of the mechanism will receive a zero speed. In the opposite direction of the input speeds or in opposite phase precession mechanism will work as the transformation of the additional link will have two inputs and two outputs with different speed ratio on them.

Thus, the proposed Converter speed are arranged in the form of a bearing Assembly of the clips without a fixed housing in which some of the clips becomes stationary when planting Converter speed to his workplace.

The invention is illustrated in graphic materials, where Fig.1, 2 and 3 shows longitudinal sections of different design options of the Converter speed made according to the invention. The diagram in Fig.4 illustrates the interaction of the beads with periodic raceways. In Fig. 5, 6 and 7 shows a longitudinal section of different embodiments of two-stage Converter with a serial arrangement of steps on two swinging washers, and Fig.8 and 9 with a coaxial arrangement of steps on one swinging the puck. In Fig.10 and 11 presents the options of the Converter speed on the basis of the transmitting node with two oscillating in antiphase washers. In Fig. 12 is a schematic diagram of the differential Converter with two independent inputs and two outputs. It should be noted that all types of structures is a first node of the inverter formed by the ferrule 1, inside of the tilting washer 2. The mating inner side surface 3 of the casing 1 and the outer side surface 4 washers 2 made in the form of a spherical zone with the center of the sphere (point C) in the center of symmetry of the casing 1 and washer 2. Swinging washer 2 installed with the possibility of precession about a point C. On the mating surfaces 3 and 4 is performed periodic Cam elements in the form of a wavy bent in the axial direction of closed raceways 5 and 6 with different number of periods. With both raceways in constant contact bulbs 7 are placed in the nests of thin-walled separator 8. The separator is located between the surfaces 3 and 4 and repeats the same form, i.e., also is a spherical zone. Nests of the separator 8 is formed through-hole. Here it should be noted that the separator is not a necessary element for transmitting nodes with a high gear ratio and high precision manufacturing raceways. In other cases, it serves to prevent angular movement of the balls relative to each other and not involved in the transfer of loads.

To simplify the manufacture of wavy-curved track 5 on the inner poverny the side surface of the casing 1, as well as the inner side surface of the tilting washer 2 may be made in the form of a hexagon for the possibility of their connection with the known, leading or stationary pressurized link. Washer 2 can be made to precessional in a variety of ways. It is important only to the swinging movement of the washers was independent of its rotation. When one wave precession washer 2 (see Fig. 4) gear profile 12 formed curved raceway 6, presses the balls 7. If the tilting washer 2 fixed against rotation, the balls 7, trying a toothed profile 12, will move through the angle corresponding to the period of the raceway 6. In his obytnom the movement of the balls are pressed on the timing profile 13 and rotate it together with the yoke 1 by an angle corresponding to the period of the raceways 5. Since each ball 7 has one touch point with toothed profiles 12 and 13, for both of them it will roll without slipping, and the rotation is transmitted by the pressure of the Cam ball 7 on the profiled Cam surface of the casing 1.

When the fixed yoke 1 on the appropriate angle will rotate the tilting washer 2. Thin separator 8 during operation of the transmitting node will swing and dramatic to to keep the balls at a certain angular distance from each other during the passage of the point E (see Fig.4), the points of coincidence of the peaks or troughs of the toothed profiles 12 and 13. It should be noted that the transmitting node swinging washer 2 may be located outside the casing 1, and the corresponding curved raceways will be located on the inner side surface of the tilting washer 2 and the outer side surface of the casing 1.

Tilting the washer 2 is additionally introduced link - clip 14 node transmitting rotation between the non-axial shafts. In Fig. 1 this unit is designed in the form of two conical gear wheels 15 and 16. Gears 15 and 16 do not interfere with the washer 2 to swing, but at the same time transmit its rotational movement of the ferrule 14. Gear, undoubtedly, affects the characteristics of the transducer, but this deterioration is not as significant, because the gearing is applied already on the low side of the Converter.

In Fig. 2, the node transmitting rotation between the swash plate 2 and an additional clip 14 is in the form of a cross (or universal joint) 17. In Fig.3 the same node represents a system of flexible rods or levers 18. All possible variants of violencei swinging washer 2 in Fig.1 represents a shaft holder 19, coaxial transmitting node and located on the side of the tilting washer 2 opposite to its working-side surface 4 with the raceway 6. Recourse to bobble the puck surface of the holder 19 is made annular ledge 20, and on the corresponding surface of the washer 2 ring closed groove 21. Between the lip 20 and the wall of the groove 21 is a ball 22. On the diametrically opposite side of the tilting washer similar to the bulb 22 is inserted between the other side of the ledge 20 and the opposite wall of the groove 21. In the washer 2 is inclined with respect to the shaft 19. When the shaft 19, the balls 22 are moved circumferentially displace the tilt washer in azimuth, i.e., washer wobbles relative to the center of precession With coincident with its center of symmetry, but does not rotate. PTO in the Converter can be as ferrule 1 of the transmitting node and the yoke 14, connected with the swash plate.

Bearings 23, 24 and 25 all nodes of the Converter are connected in a single unit, resembling a bearing with three rings: an outer race 1, the intermediate 14 and 19 internal. In the case of the gear ring 19 is input, one of the clips 1 or 14 fixed in the housing, and the other is the output gear BL the source, the speed across the cage will depend on the speed ratio on the differential inputs of the Converter.

Means for excitation of the precession of the swing washer 2 in the Converter of Fig. 3 is executed as described above, only on the shaft 19 is made no protrusion and the groove 26, and on the surface of the tilting washer made the ledge 27. Between the lip and groove put two balls 22.

Means for excitation of the precession of Fig.2 is a yoke 19 with an oblique crank 28. Swinging washer 2 planted in oblique crank shaft by means of bearings 29.

In a two-stage Converter with a serial arrangement of steps (Fig. 5, 6, 7) optional element is a second swinging washer 30, and the precession of the washers synchronous. Swinging washer connected between a node for transmitting rotation between the non-axial shafts. In Fig.5 and 6, this node is a parallel crank with ball link. This mechanism is performed on the end facing to each other surfaces of the washers 2 and 30 holes 31 and 32 and the balls 33. The axis of the holes evenly spaced around the circumference of each of the washers, and the diameters of the holes is larger than the diameter of the balls 33 on Velich is to a and B. When the precession of the spacers beads 33, trying holes 31 and 32 allow the washers 2 and 30 to move, but do not allow them to rotate relative to each other. Washers do relative to each other plane-parallel movement, but rotate together. That is, the rotation of one of the washers will cause rotation of the other. In Fig.7, the rotation of the washer 2 washer 30 is transmitted to the common shaft 34 along the axis of the transducer. On the shaft 34 by means of cross-pieces 35 and 36 secured both swinging washer.

On the side of the tilting washer 30 is made periodically curved along the axis of the transducer, the raceway 37. Together with the raceway 38 turned on the washer 30 and a side surface of the additional clip 39 and the balls 40, it forms the second transmitting node, similar to the first, but perhaps with a different gear ratio. For fixing the angular position of the balls 40 when passing them at the same time the peaks and troughs of the periodic raceways 37 and 38 is a thin separator 41, the holes which are located balls 40.

Means for excitation of the precession of the second swinging washer 30 in Fig.5 is an oblique crank 42 on a common shaft 19. For synchronous precession of the washers 2 and 30 crooked scythe is hydrated shaft 42 by means of bearings 43.

The means of excitation of the precession of the washers in the Converter of Fig.6 are the same as in Fig.3, there is a yoke 19 with the groove 26. Recourse to the shaft 19 of the side surfaces of the washers 2 and 30 is made annular projections 27. The tabs 27 mates with the groove 26 by means of two balls 22, which are located diametrically opposite each other between the wall of the groove 26 and lip 27. To ensure the slope of the washers 2 and 30, the balls 22 are located between the opposite walls of the groove 26 and the annular ledge 27.

For the two-stage Converter with posledovatelnyi location of the transmitting nodes, we developed an original mechanism of excitation of the precession of the washers.

The Converter speed with such a mechanism is shown in Fig. 7. It contains a shaft holder 44 with the ring 45 located between the stages of the Converter. The ring 45 protrudes outside of the outer casing 1 and 39. The yoke 44 is made with two oblique cranks 46 and 47, on which the bearings 48 and 49 are planted swinging washer. This design is intended for transmitting rotation between intersecting shafts. The outer crown ring 45 is performed as part of the worm, bevel gear or friction gear. On Le PTO can be produced simultaneously from the clamps 1 and 39, therefore, the Converter is very effective as a reducer of the rear axle of the vehicle. Figures 23 and 24, as in the previous figures are denoted by the bearings connecting the transducer elements with each other.

Two-stage Converter with a serial arrangement of steps is as follows. Assume that the fixed ferrule 1 of the transmitting node of the first stage. When the shaft 19 or 44 with angular velocity1swinging washer 2 starts precessional with the same speed and, acting on the balls 7, causes them to our teams on the stationary raceway 5 on the holder 1 with speed2depending on the number of periods of the raceway. Ubcatnoe movement of the balls 2, in turn, will cause rotation of the washer 2 relative to the chains of balls, which depends on the number of periods raceways 6 a swinging washer 2. Relative to the stationary casing 1 (relative to the body) washer 2 will rotate with angular velocity3which is a function of the number of periods of the raceway 5 on the holder 1 and 6 on the plate 2. Balls 33 parallel crank or clip 34 with cross pieces 35 and 36, this rotation is transmitted to the washer 30, which simultaneously with the rotation precessive with angular and track 38 on the yoke 39, will cause rotation of the latter relative to the washer 30 by an angle determined by the ratio of the periods of raceways 37 and 38. The total rotation of the slave holder 39 will depend on the1,2,3and, ultimately, will be determined by the number of periods of all four raceways for swinging the washers and clips of transmitting nodes in both stages. The center of precession of the chain of balls 7 is point a and the center of precession of the chain of balls 40 - point, which coincide with the centers of symmetry of the respective washers. That is, the precession of every chain of balls is about a point lying in the plane of the chain, which greatly simplifies requirements for the periodic profile raceway.

In the scheme of two-stage Converter of Fig.8, 9 both stages are implemented on the one swinging the washer 2. To do this, on its side surface opposite the working surface with periodic raceway 6, made periodic raceway 52. The raceway 52 is one of the interacting parts of the second stage Converter. Another link is the raceway 53, fulfilled on the side of extra clips 54. Raceways 53 and 54 are Obadiah thin separator 56.

In the Converter of Fig.8 shaft for excitation of precession is made in the form of two polumbaum 64 and 65, entered between clips 1 and 54 of the transmitting nodes of the first and second stages to the opposite ends, and installed between carriers with bearings 66, 67, 68, 69. Both polumbaum 64 and 65 are made with oblique cranks 70 and 71. On them by means of bearings 72 carried by a rocking washer 2. The input link of the Converter can be either polumbaum 64 or 65.

Means for excitation of precession in the Converter of Fig. 12 differs from the previous one only by the fact that polyamoury 64 and 65 made of the same face Cams 73 and 74. End Cams affect the tilting washer 2 through the bearings 75.

Two-stage Converter with one swash plate works as follows. The rotation of the input shaft 64 causes the precession of the swing washer 2 relative to its center of symmetry of the point D. the Rotation of the input shaft is not transmitted swinging the puck, because it is connected to a shaft bearings 72 or 75. The swinging movement of the washer 2 causes pressure on the balls 7 from the side of the zigzag curved raceways 6. If the clip 1 to fix still, the balls 7, trying a stationary periodic activities is to promote washer 2 raceway 6 rotates relative to the chain of rolling elements 7 by an angle defined number of periods of the raceway 6. The total rotation of the washer 2 relative to the stationary casing will depend on the ratio of the periods of tracks 5 and 6. At the second stage of the Converter washer 2 in addition to the rotation precessive with the rotational speed of the input shaft. This movement of the washer with balls 40 that interacts with the raceways 37 and 38, is transferred to the yoke 39 of the transmitting node of the second stage with a gear ratio determined by the ratio of the periods of raceways 37 and 38. Thus, the total gear ratio of the Converter is determined by the ratio of the number of periods of the raceways of both steps.

Refer to the converters in Fig.10, 11 and 12 in which both of the shroud 76 and 77 of the sending node is configured to precession and are swinging washers. On facing to each other of the side surfaces of the clamps in the form of a spherical zone made periodic elements in the form of curved raceways 78 and 79. In this transmitting node when the total angle between the washers are equal , the angle of each washer to the axis OO1is /2. That is, the precession angle of each of the spacers is reduced by two times, which creates more favorable conditions for the operation of the mechanism, who is from each other, i.e. precess at out of phase. This precession provides a mechanism that represent two hollow shaft 80 and 81, connected by a cover 82. The shaft 80 is located outside the transmitting node and the shaft 81 is inside. On the side facing each other, the surfaces of the shaft 80 and the washer 76 is made closed annular groove 83 and the annular protrusion 84. A similar groove 85 and the protrusion 86 is made to face each other, the surfaces of the other pair of shaft 81, the swinging washer 77. Between the wall of the groove 83 and the annular projection 84 on one side of the washer 76 and between the opposing wall of the groove 83 and the opposite side of the protrusion 84 on the diametrically opposite side of the washer put two balls 87. Similarly, between the groove 85 and the tab 86 introduced two ball 88, the balls 87 and 88 are located relative to each other so that they provide the opposite slope of the washers 76 and 77. Washers 76 and 77 are connected with the sleeves 89 and 90 nodes transmit rotation between the non-axial shafts. In Fig.10 is a system of levers or flexible rods 91 and 92, and Fig.11 and 12, these sites are made in the form of bevel gears 93 and 94.
