transport engineering; muscular drives. SUBSTANCE: proposed muscular drive has planetary gear train with carrier 3 and two planet pinions 6 arranged in housing 1. Carrier 3 is made in form of chain drive sprocket and is provided with eccentric projections 5, one on each end face surface. Projections 5 are spaced through 180°. Planet pinions 6 are fitted on eccentric projections 5 and are provided with one support tenon 8 on each and face surface to transmit muscular effort and are mechanically coupled with two stationary central gears 7 with internal teeth. Distance from support tenon 8 to eccentric projection 5 and from eccentric projection 5 to axis of rotation of carrier are equal to each other comprising quarter of the length of working stroke of support tenon 8. Proposed invention makes it possible to displace support tenons 8 along straight line. EFFECT: improved convenience of usage. 1 dwg
