WAVE TRANSMISSION Russian patent published in 2020 - IPC F16H1/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to wave transmissions. Wave transmission comprises rigid and flexible gear wheels, wave generator for bending of flexible wheel with formation of its engagement sections with rigid wheel in positions, which are separated in circumferential direction, and to move engagement sections in circumferential direction, and non-clamping area formed in part of each of engagement sections in direction of tooth line. Flexible and rigid wheels are straight-toothed cylindrical gear wheels or helical cylindrical gear wheels having one tooth line. Wave generator comprises a wave bearing for supporting a flexible wheel with its radially inner side, and the non-clamping area is an area having such a width in the direction of the tooth line, which includes a wave generator support centre for supporting the flexible wheel. Uncoupling area is set in the direction of the tooth line by the section on which the internal teeth of the rigid wheel are not made, and the flexible wheel has a rib formed on the section facing the section on which the internal teeth are not made, and external teeth formed on both sides of rib in direction of tooth line, wherein rib has thickness exceeding thickness of rim of external teeth root base.

EFFECT: improved operational characteristics of transmission.
