Reversible, infinitely variable wedging element, force transfer device

摘要

A force transfer device 30 includes an inner race 40 and an outer race 38 and a plurality of reversible wedging elements 34 located between the inner and outer races. This device 30 allows for continuous force transfer between the inner and outer race. This device 30 further allows for locking the inner race 40 relative to the outer race 38 in infinitely varying positions. The device 30 includes scallops on at least one race which scallops are of complex shape in order to manage wedging of the wedging elements and surface stresses between the wedging elements and the race contact surfaces. The device 30 is also reversible.
