Abstract
This spider assembly comprises a spider which comprises a hub intended to be connected to a shaft and from which there project several arms (3). Each arm comprises a cylindrical runway surface (12), a roller (5) mounted to rotate and slide on each arm via a ring of needles (4), and a split elastic ring (8) for retaining the ring of needles and the roller on the arm. The ring is axially fixed by snap-fitting onto the arm, the width of the split in the ring after mounting being zero or very much smaller than the diameter of the needles. The ring comprises, on its interior face (16), both a needle-retaining surface (20) that is flared towards the free end of the arm and delimits the space in which the needles run, and a roller-retaining surface (22) that is flared towards the free end of the arm. The flared roller-retaining surface is more or less in the continuation of the flared needle-retaining surface (20).
