ABSTRACT:
A high capacity universal joint has a larger cross with larger bearings surfaces. The cross has a heavier main body with four legs, the diameters of which are larger than those of a standard cross used with yokes of a given size. The cross can also have longer trunnions to provide larger bearing surfaces. The yokes have two arms with bores and with locating surfaces adjacent the bores. The cups for races can be deeper and extend beyond outer surfaces of the arms with the cups having recessed locating surfaces in coplanar relationship with the yoke locating surfaces and held in position by machine screws. Closed ends of the cups have lubricating fittings with standpipes extending into recesses in the ends of the trunnions. Two rows of bearings separated by an annular ring are located between the trunnions and the cups, and seals in the open ends of the cups urge the bearings toward the closed ends thereof.
