Motion transmitting device with epicyclic reduction gearing, epicyclic reduction gearing and manipulating arm

Abstract

A device for transmitting motion between a motor (8, 8a) and a mobile element, comprising an epicyclic reduction gearing with a first sun wheel (2.1) and a second sun wheel (2.2), coaxial to each other and connected by transmission means to at least one first planet wheel (3.1) and a second planet wheel (3.2) respectively, which are carried coaxially to each other by a planet carrier (5) mounted to pivot eccentrically around the axis of the sun wheels, characterized in that the transmission means comprise flexible transmission elements (6a, 7a) wound respectively around the first sun wheel and the first planet wheel, and around the second sun wheel and the second planet wheel. Epicyclic reduction gearing and manipulation arm comprising such a device.
