FIELD: machine building.

SUBSTANCE: rotary-vane coupling comprises a rotor with one or more blades rigidly fixed at the rotor, a driven flange with the contact maker axis, a contact maker rotating under the action of the blades around the geometrical axis being eccentric in respect to the rotor axis, a lock ring. The rotor is fitted by a driving flange with the blades being mounted on its side surface. The lock ring can travel along the rotor rotation axis and form a working cage between the internal surface of the lock ring, external radial surface of the contact maker, side internal surfaces of the driven and driving flanges.

EFFECT: transmission of rotary motion or torque from the shaft to the part mounted loose on it.
