Abstract
La présente invention concerne une bague de court-circuitage (1) destinée à une cage de court-circuitage d'une machine électrique. La bague de court-circuitage (1) comprend au moins un évidement, de préférence plusieurs évidements, pour loger au moins une tige de cage (3), de préférence plusieurs tiges de cage, la bague de court-circuitage (1) étant formée pour recevoir une extrémité de la tige de cage (3). Un creux ayant un contour (4, 5, 6, 7, 8, 9) est formé de manière contiguë à au moins un évidement à une extrémité axiale avant (12) de la bague de court-circuitage (1). La présente invention concerne en outre un procédé de connexion d'une bague de court-circuitage (1) de ce genre à au moins une tige de cage (3), de préférence à plusieurs tiges de cage, pour la fabrication d'une cage de court-circuitage.
