Electric motor actuator and shaft-hub connection

摘要

The actuator has a drive shaft drive-technically arranged downstream to a drive motor. The shaft is associated to a two-piece shaft-hub-connection arrangement (3) for transmitting a drive moment. The arrangement exhibits a locking ring (5) attached on a base ring (4). The base ring is attached on the drive shaft for transmitting the drive moment. The transmission of the drive moment requires a radial frictional connection between the drive shaft and the base ring. The locking ring secures the radial frictional connection by the non radial form-stable base ring. An independent claim is also included for a method for assembling a shaft-hub-connection arrangement.
