Abstract
The method permits mass-producing axially retained tripod joints having high rigidity and a given prestressing force which is reproducible from one joint to another. According to this method, after having clipped a resiliently yieldable attachment onto a tulip-shaped element of the joint while the joint is in its assembled position, the value of the gap between the shoulder of a thrust member and a bearing surface of a hub carrying the trunnions is determined for the position of the joint in which the hub and tulip-shaped member are in alignment and the thrust member is axially shifted away from the hub and there is introduced in the gap produced between the thrust member and the hub a shim the thickness of which is chosen to be slightly larger than the gap.
Claims4
A method for axially prestressing a homokinetic joint comprising a first tulip element for rigidly connecting to one of two shafts to be interconnected and defining raceways, a second element for rigidly connecting to the other of said shafts and comprising a hub and trunnions extending from the hub, the hub defining an axial bore and a radial bearing surface, rollers respectively rotatively and slidably mounted on the trunnions and received in the raceways of the first element, an axial retaining device comprising at least one thrust member slidably mounted in the axial bore of the hub, said thrust member comprising a radial shoulder in facing relation to the radial bearing surface of the hub, and a resiliently yieldable attachment fixed to an end of the tulip element, said method comprising, clipping the resiliently yieldable attachment onto the tulip element while the joint is in an assembled position, then determining for a position of alignment of said first and second elements the size of a gap between the shoulder of the thrust member and the bearing surface of the hub, axially shifting the thrust member away from the hub, and introducing between the thrust member and the hub a shim having a thickness which is so chosen as to be slightly larger than said gap, thereby providing an axial prestress between said thrust member and said hub and thus between said first and second elements.
