WAVE GEAR TRAIN Russian patent published in 1999 - IPC

FIELD: machine elements; drives of articles in aeronautical engineering and rocketry. SUBSTANCE: the following components are coaxially mounted in housing of wave gear train: input shaft and hollow output shaft, rigid wheel, wave generator, flexible and rigid wheels and torque-limiting clutch. Wave generator is mounted on output shaft in bearings and is connected with input shaft through intermediate gear train consisting of "n" (n=1,2, etc.) satellites whose axles are immovable relative to output shaft. Flexible wheel is connected with housing and is thrown into engagement with rigid wheel. bearings of output shaft are arranged in housing on different sides from wave generator. Output shaft is provided with "n" cuts for satellites. Axles of satellites are secured on output shaft. Rigid wheel is mounted on output shaft for rotation about it. Torque-limiting clutch members are made in form of output shaft and rigid wheel. EFFECT: enhanced reliability of protection of output shaft against overload without increase of overall dimensions. 1 dwg
