1,193,738. Universal joints. BORG-WAR. NER CORP. 23 Aug., 1968 [14 Sept., 1967], No. 40398/68. Heading F2U. A universal joint with means for compensating for wear of the rubbing surfaces comprises a tang 13 on one shaft received in a slot 35 having walls 33, 34 diverging towards a face 36 in a bushing 17 which is received in a cylindrical socket 14 provided on the other shaft. A wedge block 18 is mounted in the slot 35 and a spring 19 between the block and the base 36 of the slot urges the bushing against the socket and urges the tang against the wall 33 of the slot. The parts of the bushing adjacent the confluence of the side walls and base of the slot are relatively thin and provide some flexibility facilitating expanding of the bushing into snug engagement with the socket. The bushing and wedge block are preferably formed of selflubricating plastics material, such as a polyamide filled with carbon black. Other plastics are also suggested. |
