PCT No. PCT/GB85/00058 Sec. 371 Date Sep. 18, 1985 Sec. 102(e) Date Sep. 18, 1985 PCT Filed Feb. 14, 1985 PCT Pub. No. WO85/03680 PCT Pub. Date Aug. 29, 1985.A sealed pivot joint suitable for joining together the adjacent links of an endless belt, for example, a tank track. The joint has a bearing (10) rotatable on a pin (8), and an elastic sleeve (20) whose extremities are in sealed relationship to the pin and bearing thereby preventing the ingress of abrasive material into, and the egress of lubricant from, the bearing surface (12). The sleeve is maintained in circumferential tension by tensioning members (14, 16, 18) between the sleeve and the pin which act to prevent wrinkling of the sleeve when the pin and bearing are rotated relative to one another thereby reducing abrasive wear on the outer surface of the sleeve. |
