FIELD: machine building.

SUBSTANCE: gear with end teeth consists of case, of driving shaft and of driven shaft with drum arranged in case so, that driving shaft with its one end is inserted in coaxial blind orifice of driven shaft forming united rotation axis, of two pairs of cam disks with end teeth, of two pair of driven rings with end teeth and of two pairs of carriers with pins. Two pairs of cam disks are arranged in a cavity of the drum of the driven shaft and are secured on the driving shaft forming an internal circular cam slot with each pair. Two pairs of rings are arranged on internal side of the drum of the driven shaft forming an external circular cam slot with each pair. In the case of each carrier there is made a slot, side walls of which are arranged at angle to axis of the pins. Walls of the slot of each carrier contact side walls of the case of another carrier and function as guides for set off of carriers one relative to another. Pins of each pair of carriers are located in circular cam slots of a corresponding pair of the driving cam disks and corresponding pair of the driven rings designed to interact with internal surface of the said slots.

EFFECT: vibration damping of driving and driven shafts and uniform rotation of driven shaft.
