Abstract
Small wells cut into the upper interior surface of the head plate collect oil that is sprayed forcefully upward by the rotating gears and eccentric weights and channels that oil through a throughbore across the width of the head plate, routing the oil into a hose or bored channel at each end of the throughbore, with oil in the hoses or bored channels flowing through bearing access ports into the bearings on the rotating eccentric weights. A separate oil collection well, throughbore and hose arrangement is provided for each of the eccentric weight and gear sets and may be provided for pinion gears connected to hydraulic drive motors.
