Rotation is transmitted to cage 1 which has slots in which inserts (teeth) 2 can slide in the axial direction. The outer ends of semiaxles A and B are connected to the driven links of the mechanism. Keyed to their inner ends and facing each other are cam disks 3 having profiled lobes on their inner (working) surfaces. The number of cam lobes on disks 3 and the number of inserts 2 are selected so that when cage 1 rotates, inserts 2 bear against the corresponding lobes of cam disks 3, rotating them together with their semiaxles. If equal torque loads are applied to semiaxles A and B, their speeds are equal and the same as that of cage 1. If one semiaxle is slowed down by higher load torque, inserts 2 are pushed by the lobes of the cam disk on this semiaxle toward the other disk and, by bearing against the corresponding lobes, increase the speed of the other semiaxle. If cage 1 is held stationary and one semiaxle is rotated, the other semiaxle rotates in the opposite direction.
