ABSTRACT:
A lubrication passageway for a universal joint which has a pair of yokes. The yokes are pivotally connected to one another and each has an axis of rotation. An annular groove is formed in an arm of one of the yokes in a plane which is spaced apart from the axis of rotation of the yoke and perpendicular to an imaginary line which is normal to the axis. A first passageway provides lubricant to the side of the groove which is distal from the centering apparatus. A second passageway provides lubricant from the side of the groove proximate to the centering apparatus to the centering apparatus. The annular groove acts as a check valve to prevent lubricant from flowing out of the centering apparatus when the joint is rotating. A sustem for lubricating a centering plate and bearings for the universal joint is also disclosed.
