Reversible type stepless variable wedge tightening entity type power transmission

摘要

(57) Abstract As for the power transmission (30), it possesses the plural reversible wedge tightening elements (34) which are provided with inner race (40), outer ring (38) and inner race and outer ring. This device (30) makes the transmission of force continual with inner race and outer ring possible. This device (30) furthermore inner race (40) to stepless variable position person in charge stopping can do vis-a-vis outer ring (38). This device (30) in order to control the surface stress with wedge tightening action and the wedge tightening element and the race/lace contact area of the wedge tightening element, being provided at least in one race/lace, has had surakatsupu (36) of complicated form. The power transmission (30) and, is reversible system.
