ABSTRACT:
A universal joint with lubricating means is provided. Heretofore, universal joints with lubricating provisions have had central lubricating fittings in the cross, with the fittings communicating with the bearing cups through lubricating passages in the cross body and trunnions. The lubricating passages reduce the cross section of the trunnions which have broken at the base in certain heavy duty applications. The new universal joint has lubricant fittings in the bearing cups and eliminates the lubricating passages in the cross. Each bearing cup has an opening with an outer surface contoured to receive the nozzle of a lubricating gun or tool. A one-way valve is located at the inner surface of the bearing cup which allows lubricant to enter the cup through the opening and keeps out contaminants.
