ABSTRACT:
A power operated chuck in which an actuator, such as a fluid pressure actuator, causes clamping or unclamping movements of the jaws in dependence on the position of a control member, in which the power for operation of the actuator is derived from rotation of the chuck on a shaft of a machine tool, the power source being housed within the chuck which is thus self contained and does not require a separate power source. In the embodiment described the power source is in the form of a plurality of fluid pressure pumps worked by a swash plate as the chuck rotates. Fluid pressure built up by the pumps is stored in a fluid pressure reservoir and used to drive the actuator.
