  • Clutch/damper
    Patent number: 4888539
    Abstract: A clutch/damper for isolating and absorbing vibration induced reactive torques from adversely affecting a motor drive system. A friction plate variably engages a gear coupled to the drive motor and to a load mass to permit normal drive in the absence of excessive reactive torque forces and to allow the motor to continue to drive against a slipping load in the presence of excessive reactive torque forces. Feedback is employed in the drive system to compensate for the small errors induced by the slippage.
