TORSIONAL DISCONNECTING SPRING Russian patent published in 2012 - IPC F16H55/36 F16D7/02 

FIELD: machine building.

SUBSTANCE: torsional disconnecting coupling includes sleeve, pulley and friction element. The latter is located between sleeve surface and pulley surface; at that, friction element is engaged due to friction with pulley surface or sleeve surface. At that, friction element transmits torque moment between the sleeve and pulley so that angular displacement appears between sleeve and pulley during transmission of torque moment.

EFFECT: reduction or elimination of hazardous effects of torsional vibrations on belt drives.
