Title
(EN) LASER WELDING OF BALANCE WEIGHTS TO DRIVESHAFTS
(FR) SOUDAGE AU LASER DE MASSES D'ÉQUILIBRAGE POUR DES ARBRES DE TRANSMISSION
Abstract
(EN)
Described herein are driveshafts (102) with balance weights (104) welded thereon and methods of manufacturing the same. The paint (112) is removed from the driveshaft (102) before the balance weight (104) is welded thereon. The paint removal and welding can be incorporated into the balancing process and equipment (210). The invention also relates to driveshaft balancing equipment (210) incorporating one of or both of paint removal capabilities (250) or welding capabilities (260).
(FR)
L'invention se rapporte à des arbres de transmission (102) sur lesquels sont soudées des masses d'équilibrage (104) et à leurs procédés de fabrication. La peinture (112) est enlevée de l'arbre de transmission (102) avant que la masse d'équilibrage (104) ne soit soudée sur ce dernier. L'enlèvement de la peinture et le soudage peuvent être incorporés dans le processus d'équilibrage et l'équipement d'équilibrage (210). L'invention se rapporte également à un équipement d'équilibrage d'un arbre de transmission (210) incorporant des capacités d'enlèvement de la peinture (250) et/ou des capacités de soudage (260).
