Plate Clutch

A clutch is a mechanical apparatus designed to transmit power, usually motion too, from one component (the driving member) to another (the driven member) when engaged, but can be disconnected. Clutches are employed where controlled transmission of power or motion is necessary, either in terms of amount or time duration. For example, clutches in electric screwdrivers regulate torque by using a clutch mechanism, while automobile clutches control the transfer of engine power to wheels. In simple applications, clutches facilitate connection and disconnection between two rotating shafts (drive shafts or line shafts). One shaft is usually connected to a motor or power source (the driving member), whereas the other shaft (the driven member) delivers output power for work. In a torque-controlled drill, for instance, one shaft is powered by a motor and the other drives a drill chuck. The clutch links these two shafts to enable them to spin at the same speed when locked together (engaged), spin at different speeds while still connected (slipping), or not spin at all when disconnected (disengaged).
