PLANETARY CYCLOID REDUCTION GEAR Russian patent published in 2000 - IPC

FIELD: machine engineering, namely gear transmissions. SUBSTANCE: planetary cycloid reduction gear includes stationary and movable central gear wheels, satellite with separator movably mounted onto eccentric of input shaft. Stationary central gear wheel is formed of toothed sectors with different angular pitches. Satellite is in the form of precision elastically deformed welded polished spring turns placed in strictly oriented recesses of separator along its periphery in such a way that outer portion of turns engages with central gear wheels with possibility of changing angular pitch in range of one tooth or part of one tooth. EFFECT: enhanced loading capacity, accuracy, efficiency, increased useful life period of reduction gear at noiseless operation of it. 4 cl, 3 dwg
