FRICTION LOCK ASSEMBLY AND RETAINING RING FOR WELLHEAD

A locking assembly and a retaining ring for retaining the locking assembly within a bore of a wellhead component are provided. In one embodiment, a system includes an inner component disposed within a bore of a wellhead component and a locking assembly disposed within the bore to secure the inner component within the bore. The locking assembly includes a lock ring that extends into a recess in a wall of the bore of the wellhead component and an actuator radially disposed between the inner component and the lock ring. The system also includes a retaining ring that limits movement of the actuator along the inner component and maintains the actuator between the inner component and the lock ring to retain the lock ring within the recess. The actuator and the retaining ring have mating tapered surfaces that inhibit movement of the actuator out of engagement with the lock ring.
