Philadelphia Gear’s Synchrotorque® line of hydroviscous clutches operates on the principle of shearing an oil film to transmit torque. This hydroviscous effect transmits torque in proportion to a variable clamping force. For unrestrained loads, the higher the clamping force, the faster the output speed. The input drive plates function as the driver. The output friction discs are faced with a suitably grooved resilient material and act as a driven member.
Precisely controlled clamping pressure between input drive plates and output friction discs allows virtually infinite speed control right up to 100% of input speed. This simple phenomenon, based on established hydrodynamic bearing principles, is the basis for controlled torque transmission in the Synchrotorque hydroviscous clutch.
