ABSTRACT:
A brake for a hydraulic device of the type in which a train of driving or driven shafts includes at least one shaft adapted for orbital and rotational motion. One or more frictional braking members are fixedly secured to the rotating and orbiting shaft, and are adapted to be frictionally engaged by a fixed member to apply a braking torque to the shaft. A preferred embodiment discloses a particularly advantageous manner in which such a braking device is applied to a hydraulic motor wherein the orbital and rotational motion of the driven shaft which is braked is provided by a gerotor gearset.
