Abstract

A hydraulic vibration generation device is provided. The device includes a manifold member having an inner volume, a fluid inlet orifice and a fluid outlet orifice. The device further includes a vibration generating member having a channel grooved drive and an off-center weight, and bearing retaining plates. The inner volume receives the vibration generating member within the inner volume. The bearing retaining plate that retain bearings operate to retain the vibration generating member within the inner volume in response to coupling the bearing retaining plate to the manifold member wherein two bearings on opposing ends of the vibration generating member are retained within recesses of the bearing retaining plates. The vibration generating member rotates and generates vibration in response to hydraulic fluid flowing into the manifold member through the inlet orifice and out of the manifold member through the outlet orifice.
