COUPLING Russian patent published in 2009 - IPC F16D17/00 F16D13/00 

FIELD: machine building.

SUBSTANCE: coupling consists of eccentric (1) rigidly connected with drive shaft (2) and of driven cylinder fixture (5) with cavity. Eccentric (1) is assembled with a gap in the aperture of bushing (3) installed on drive shaft (2); bushing (3) is located with a gap in the cavity of fixture (5). The axis of the aperture of bushing (3) is set off relative to the axis of the bushing (3) and to the axis of drive shaft (2). A recess is cut in the end of bushing (3) from the side of the interior end surface of fixture (5); spring (4) installed in the said recess facilitates alignment of bushing (3) with shaft (2) of a motor.

EFFECT: simplification of design, increased service life of coupling and facilitating transfer of torque at direct and reverse motor rotation.
