MOTOR WITH BRAKE, AND ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2017/164400
Kind Code:
A1
Abstract:
As a brake for holding the rotation direction position of an output shaft (13) when a motor (1) is stopped, a reverse input blocking clutch (11) is used having a structure whereby when the motor (1) is rotated, a cam receiver (12) rotates as an integrated unit with a motor shaft (3), and by eccentric rotation of an eccentric cam (14) fitted so as to be relatively rotatable in an eccentric hole (12c) of the cam receiver (12), an output shaft (13) rotates as an integrated unit with the eccentric cam (14), and when the motor (1) is in a stopped state, even when reverse input torque is applied to the output shaft (13), the eccentric rotation by the output shaft (13) around an eccentric axis line (O2) is regulated and locked by a brake housing (15), thus holding the rotation direction position of the output shaft (13).
