Title (EN) CROSS FOR A UNIVERSAL JOINT
(FR) CROISILLON POUR CARDAN
Abstract:
(EN) A cross (1) for a universal joint has axial recesses (11a) in the ends of the arms (2a). In the outer part of each of these recesses (11a) there is pressed-in a reinforcing plug (13a). By these means, each arm receives a modified elasticity which leads to a more uniform load on the bearing, with which the arm is intended to interact. This leads to improved bearing life.
(FR) Un croisillon (1) destiné à un cardan comporte des évidements axiaux (11a) situés dans les extrémités des bras (2a). Dans la partie extérieure de chacun de ces évidements (11a), on fait entrer par pression une cheville de renforcement (13a). Grâce a ces moyens, chaque bras est doté d'une élasticité modifiée permettant d'obtenir une charge plus uniforme sur le support avec lequel le bras est destiné à agir mutuellement. Cet agencement permet de prolonger la durée de vie du support.
