This kind of gear transmission box is not a torque transmission part, that is, it is a non-loading part. At the same time, it should be pointed out that adding a gear transmission box will make the points that apply force to the ball more deviate from the axis passing through the center of the ball, thus making the distribution of force even worse. uniform

Embodiment Construction
[0031] figure 1 , the transmission in 3 and 4 consists of three bushings, Figure 5 and 6 The four components of , the relative positions of the intersecting surfaces are different, Figure 12 The transmission device consists of five bushings. In all the above-mentioned figures, 1 represents the wave generator bearing, 2 is the rolling element-ball, 3, 4, 5 and 6-the bearing of other transmission devices. The sockets are arranged relative to each other such that each socket is conjugate to its two adjacent sockets ( figure 1 , Socket 1 of 3, 4 is conjugated with sockets 3 and 4; Figure 5 and 6 The sleeve 1 is body conjugated with sleeves 4 and 5). In addition, at least two sockets are conjugated along their intersecting faces ( figure 1 sockets 1 and 4, image 3 Examples 3 and 4, and all examples in other figures). Therefore, all sockets (examples) are tangent to each other around a circle. Along this circle, examples 1, 3, 4, 5 and 6 all have circumferential groove...

The inventive differential rotation speed transducer can be used for drives of general use machines and mechanisms. Said transducer relates to gears provided with intermediate members and comprises a wave generator and a transferring unit which is embodied in the form of coaxial cases (1, 3, 4,5) mated to each other around a circle. Clutch surfaces are embodied in the form of periodical roller ways interacting with a chain of balls (2) on each clip along the trace of said circle. The case (1) is linked to the generator and embodied in such a way that it affects rolling bodies in the direction selected from any directions on the plane of the axial section of the transducer. The unit comprising four cases is used for transferring increased power. Spaced in azimuth grooves are embodied on two cases which are oppositely disposed with respect to the chain of balls and mechanically connected to each other. Said unit being provided with greater number of cases, the additional links having other gearing ratios occur. A thin-wall separator provided with through grooves for displacing the rolling bodies can be introduced between the mating surfaces of the cases. Said separator is embodied in the form of an rotation surface provided with one or two reinforcing ribs and a swell arranged in the space between roller ways. The case of the generator can be embodied in a coaxial form with respect to other cases and mounted in such a way that it is precessional. In order to extend the range of gearing ratios, the roller way disposed on the side surface of the case is embodied in the form of a closed groove zigzagging in an axial direction.
Description
technical field [0001] The invention relates to a transmission device for speed conversion and can be used for general machinery and the drive of such machinery. The transmission works on the principle of wave gear transmission through an intermediate component. Background technique [0002] Wave gears are well known (see "Transmissions and Electric Machines - Transmissions for General Engineering". References L.S. Boyko, A.Z. Visockyi and other authors. - M: Mashinostroyenie (Machine Manufacturing), 1984, pp. 22-29; RU№2019760). In a nutshell, the gear consists of three basic components: a fixed gear, a moving gear and a wave generator. The wave gear has a high transmission ratio (up to 1:350 in one stroke), but its efficiency is low due to energy loss due to friction generated by the deformation of the driving wheel and the meshing of the teeth. [0003] Energy losses due to friction between meshing teeth and deformation of the drive wheel are eliminated by means of wav...
