ABSTRACT:
An adjustable hydraulic speed drive for controllably maintaining output torque and variable output speed is disclosed. The drive utilizes a rotating group of pistons in radially arranged bores in a portion of an input shaft. A supply of controlled fluid is provided to the bores by way of passageways in an output shaft communicating with said bores. A portion of the output shaft supports a cam ring in spaced relation to said bores and roller ends on said pistons engage said cam ring by centrifugal force upon rotation of the input shaft so that the pistons move responsive to the cam ring contours, said impart movement to the cam ring and output shaft by controlling the pressure level and/or flow rate of the fluid exiting from said bores.
