1,188,398. Universal joints. QUINTON HAZELL Ltd. 2 Dec., 1968 [12, Dec., 1967], No. 56357/67. Heading F2U A sleeve, intended for, a universal joint, is made, of a hard material and has a, cylindrical. bore 58, Fig. 1, for mounting on a spider arm 48 and a circumferential surface comprising an annular groove 66 Between the ends of a frustoconical formation whereby the bridge 68 of a U-bolt is received in the annular groove to clamp the sleeve in a complementary seat 30 in a yoke joint. The drive is transmitted through a spider 38, having lubricant passages 86 and arms having cylindrical portions 48 which form the inner race rings for needleroller bearing units 50. The latter have outer race rings 55 which engage shoulders 60 in the sleeves 42. A sealing ring 62 prevents lubricant loss. The outer race rings 55 or the needle roller may be omitted so that the cylindrical portions or the needle rollers can engage the sleeve bores either directly or via a plain bush. The end wall 56 may be separated from the cylindrical wall 55 or omitted entirely and the outer end of the sleeve closed By a wall (90), Fig. 3 (not shown). In a modification an end wall 56 can abut a circlip (92), Fig. 4 (not shown,) in the sleeve bore. In further modifications the sleeves are split longitudinally and have either an external longitudinal rib which locates the half-portion in its yoke or have complementary ribs and grooves, flanges and recesses or spigots and sockets formed in identical half-portions. The sleeves may be of steel or of a sintered material which includes iron, copper or carbon or of acetal resin.
