ABSTRACT:
A rotary actuator apparatus provides compound rotation at its output in two planes perpendicular to one another. This compound rotation is utilized in positioning a workpiece or in positioning a rock drill on the boom of a vehicle. A rotary rack and pinion actuator has an output pinion shaft rotatably mounted in an external housing and a piston driven rack in a cylinder at right angles to the output shaft housing. This cylinder is welded to the output shaft housing so that the cylinder can transmit rotational torque to the output shaft housing.
