Arrangement of two elements which undergo alternating relative motion and its application of slidable homokinetic joints

摘要

A row arrangement of needles (17) maintained in a plate (18) is interposed between a raceway (13) and a slide or bush (14) which itself cooperates with a trunnion (11). The needles have a diameter which progressively increases from the center of the row to the end needles so as to achieve a self-centering of the plate.
