Document Type and Number:
WIPO Patent Application WO/2023/042613
Kind Code:
A1
Abstract:
An electric actuator 1 comprises: an electric motor 4 having a stator 41 and a rotor 42; a motor axis 51 provided on the inner diameter side of the rotor 42 and rotating integrally with the rotor 42; decelerators 5a, 5b disposed on the inner diameter side of the motor axis 51 and decelerating the rotation of the motor axis 51 to transmit the rotation; and a lubrication flow path F through which a lubricant passing through the decelerators 5a, 5b flows. The motor axis 51 partitions a space in which the electric motor 4 is disposed and a space in which the lubrication flow path F is disposed in the axial direction across the entire these spaces.
