FIELD: machine building.SUBSTANCE: invention relates to machine building, particularly, to high-speed mechanical drives. Planetary gear includes eccentric shaft, two satellites with external teeth in internal engagement with fixed central wheel, disk is rigidly connected with driven shaft by ties, rollers with spherical surfaces, arranged in holes of satellites and disk at an angle to axis of the transmission and two fixed on camshaft counterweights with centers of gravity shifted in the side opposite eccentricities of camshaft. Wherein counterweights' mass, distance between them and their centers of gravity shift relative to the axis are selected in a way that inertial forces and moments affecting them, satellites and eccentric shaft are mutually balanced.EFFECT: reduced vibration of the planetary gear is obtained.1 cl, 3 dwg |
