ABSTRACT

A self-locking drive, usable in a linear actuator, includes a housing and a
drive shaft for outputting a driving force. An endcap is provided at an end
portion of the housing. A self-locking mechanism configured to apply a
self-locking force to the drive shaft is provided in the endcap. The
self-locking mechanism includes a friction seat sleeved over the drive shaft
and rotatable synchronously with the drive shaft, and a friction ring mounted
in the endcap and secured to the endcap. The friction seat is
interference-fitted with the friction ring to enable two-way self-locking to
the drive shaft.
