| 摘要 |
This spider for a universal joint includes a central body (2) intended to be connected to a shaft and from which several arms (3) project, a roller (5) mounted so that it can roll and slide on each arm (3) by means of a ring of needles (4), and a member (8) for retaining each roller (5) on its arm (3). The arm (3) includes a hollowed peripheral raceway (12) in which the needles (4) run. The retaining member includes a collar (8) mounted at the end of the arm and spaced away from the needles (4), which collar has, on the outside, over at least most of its periphery, a rim (18) for positive retention of the roller.
