WAVE-TYPE PLANETARY FRICTION REDUCTION GEAR Russian patent published in 2004 - IPC

FIELD: mechanical engineering+ADs- wave-type planetary friction variable-speed drives. SUBSTANCE: proposed planetary friction variable-speed drive includes external tubular housing 1, internal cylindrical housings 2 and 3 with running surfaces 12 directed towards internal surface of external housing. Axle 6 of drive, load-bearing axle 7 with flange 19, load-bearing pins 15 located in pairs on end surfaces of internal housings 2 and 3 and on flange 19, three unbalanced masses located on axles 5 in internal housings 2 and turned through angle of 180 deg. relative to each other+ADs- drive is also provided with splined joints 9 for connection of axles of drive and internal housings. Rotation from axle 6 is transmitted to all axles 5 with unbalanced masses 16 and17 which form centrifugal forces transmitted to internal housings 2 and 3 whose running surfaces 12 are pressed to radial bores 13 of external housing. EFFECT: enhanced reliability and efficiency. 3 dwg
