Abstract

The invention relates to mechanical engineering and can be used in various areas of the national economy for the transmission of rotation with the conversion of speed and moment. The aim of the invention is to increase the QPS and the durability of the wave transmission. This is achieved by improving the working conditions of the rolling bodies in the wave generator when, when the input shaft 2 rotates, the cam 6 deforms the flexible wheel 4 through the hollow disks 7. In this case, the disks 7 are separated by separators 9 and are at a certain distance from each other. in the longitudinal and in the circumferential directions. 2 Il.

The invention relates to a machine construction and can be used in various areas of the national economy for transmitting rotation with pre- formation of speed and moment.

The aim of the invention is to increase the efficiency and durability of wave transmission by improving the working conditions of rolling bodies in a wave generator. Yu

FIG. 1 shows a wave transmission, a longitudinal section J in FIG. 2 —a transverse section A-A in FIG. one.

The wave transmission includes a housing 1, an input 2 and an output 3 shafts, a flexible wheel 4 connected to the output shaft 3 and a rigid wheel 5 fixed to the housing 1 fixed to the input shaft 2 is a cam 6, the outer surface of which is up to the disk of the waves at a certain distance from each other reduces the area of the rubbing surfaces, improves the working conditions of the rolling bodies, and, consequently, increases the efficiency and durability of the wave transmission.

roller for longitudinal rows of narrow hollow disks 7 having central holes. The discs 7 are outside covered by a flexible ring 8, inserted inside the flexible wheel 4. Between the discs 7 there are separators 9, made in the form of flat gaskets with projections 10. The projections 10 are located on the ends of the separator 9, interact with the central openings of the discs 7 and serve keeping them at a certain distance from each other, which is determined by the kinematics of the wave transmission.

The axial fixation of the flexible ring 8 is carried out by means of a ring 11, which is installed with the possibility of interaction with the disks 7. Wave transmission works as follows.  When the input shaft 2 rotates, the cam 6 associated with it rotates, which through the disks 7 deforms the flexible ring 8 and the flexible wheel 4. Due to the deformation and engagement with the rigid wheel 5, the flexible wheel 4 receives a slow rotation and informs its output shaft 3 in the direction opposite to the direction of rotation of the input shaft 2. Thus, by keeping 20 25 Invention Formula A wave gear, comprising a housing, flexible and rigid wheels, input and output shafts, a cam wave generator with hollow discs arranged in rows along the transmission axis, differing from. by that. due to the improvement of the working conditions of rolling bodies in the wave generator, the disks of the latter are separated by separators in the form of flat gaskets with Yu Compiled C, Kotelnikov.
