WIPO Patent Application WO/2019/059298
Kind Code:
A1
Abstract:
An electric actuator 1 is provided with: an electric motor unit 4; a stationary member 6; a speed reducer 5 which transmits the rotation of the electric motor unit; an input rotating body 2 into which a driving force is input from outside; and an output rotating body 3 which is coupled to the speed reducer 5 and is capable of rotating relative to the input rotating body 2. The speed reducer 5 is provided with an internal gear 16 which performs an eccentric rotating motion relative to a center O of the output rotating body 3, and a support member 15 which is driven in rotation by the electric motor unit 4 and supports the internal gear 16. The support member 15 is supported by a pair of rolling bearings 17, 18, and a preload is applied to the pair of rolling bearings 17, 18.
