Patent

CA 2156546

An integrally cast bearing adapter arrangement is provided in the pedestal of a railcar truck side frame, which side frame is cast with a pedestal jaw having a roof, and vertical walls of a first and second leg which roof and walls operate as a bearing adapter to receive a bearing assembly for an axle end without introducing the manufacturing and assembly tolerances from discrete component assemblies, thereby avoiding the lateral displacement associated with the added tolerances and operating to minimize angular displacement between each mated axle and side frame.

L'invention concerne un adaptateur de palier moulé pour la plaque de garde d'un châssis latéral de bogie, lequel châssis latéral est moulé avec une mâchoire de plaque de garde comprenant un toit, et des parois verticales d'une première et d'une deuxième patte, le toit et les parois jouant le rôle d'adaptateur de palier permettant de recevoir un palier destiné à l'extrémité d'un essieu sans introduire les tolérances de fabrication et d'assemblage de composants distincts, ce qui permet d'éviter le déplacement latéral associé aux tolérances supplémentaires et de minimiser le déplacement angulaire entre chaque essieu et châssis latéral accouplés.
