Differential gearing has drive device with two intermediate members supporting an output part which undergoes a first movement when intermediate members are moved in same direction and a second superimposed movement when they are driven

摘要

the differential gearing has a drive device (38,46) and two intermediate members (10,12) and output part (14) supported on same through inclined faces (21, 22). When the intermediate members are moved in the same direction the output part carries out a first movement and when the intermediate members are driven at different speeds a second movement is superimposed on the first. The intermediate members have in relation to their direction of movement engagement faces set side by side and driven in the same direction and at different speed by the drive device.
