  • Lock ring segments biased into locked position while retained in position with an exterior profile
    Patent number: 10760363
    Abstract: Ratchet locking segments permit one direction relative movement and then prevent reverse movement to hold a set position of a tool. The segments are axially supported in a surrounding housing using an exterior profile on each segment meshing with a conforming profile on the outer housing. The meshing is loose to allow the segments the ability to move radially while supported axially. Biasing of opposed ratcheting segments toward each other is provided by a spring or springs at opposed axial ends of each segment or within the exterior profile between the axial ends. The end biasing can be done with coiled springs or bent tabs that store potential energy when assembled or with wave springs between the segment outer profile and a surrounding outer housing.
