ABSTRACT:
A hydraulically driven rotary vibrator that includes a motor body and a pair of opposed housings. Each housing includes a shaft, and an eccentric weight that are journalled by a pair of anti-friction bearings. The shaft of each housing extends a selected distance beyond a first end of the housing. A gear is attached to the extending end of the shaft. The gears associated with each of the housings are aligned and meshed with each other interior of the motor plate. The gears and their associated shafts are rotated when a hydraulic fluid is introduced into a motor chamber formed in the motor plate. The eccentric weights may be selectively phased for producing a determined vibratory output.
