ABSTRACT:
The present invention broadly comprises an assembly for incrementally changing an axially fixable position, including an annular gripping element with at least one deformation segment, a glide push ring axially displaceable along a pilot element, and a wedge push ring axially displaceable along the pilot element. The gripping element is in contact with a circumference of the pilot element and the deformable segments are circumferentially deformable in response to a change in a gripping element diameter. The glide ring incrementally urges the gripping element in a first direction along the pilot element. The gripping element axially fixes responsive to force applied by the wedge ring in a second direction, opposite the first direction, along the pilot element. A surface between gripping element inner and outer circumferences forms a fixed angle with the pilot element despite changes in the inner or outer circumferences.
