Title:
駆動アクチュエータ
Document Type and Number:
Japanese Patent JP6836335
Kind Code:
B2
Abstract:
An actuator drive, for blinds, roller shutters and the like, has a drive motor (11) and a centrifugal brake (9). A rotational disk (4) is coupled to a drive shaft (7) of the drive motor (11) via a shaft flange (5). Two centrifugal shoes (2) are smoothly guided in the rotational disk (4). In the unpowered state, brake shoes (8) of the centrifugal shoes (2) engage, frictionally or in a positive-locking way on an outer surface of a friction ring (3) fixed to the motor housing (14). Upon starting of the drive motor (11), the brake shoes (8) release the friction ring. The radial displacement of the brake shoes (8) is maintained until the drive motor (11) comes to a stop, wherein the brake shoes (8) are drawn radially inward by spring elements (6) and function again as a locking mechanism. The spring elements (6) are pretensioned such that the brake shoes (8) effect a sufficient retaining torque.
