Abstract

L'invention concerne une unité d'entraînement électrique (10), notamment un moteur électrique (11) avec une boîte de vitesses (12), dont l'arbre d'entraînement (15) est monté solidaire en rotation côté boîte de vitesses dans un roulement à billes (16) sur le carter (14) de la boîte de vitesses, qui est fixé en direction axiale d'une part sur un épaulement de butée (18a) de l'alésage de palier (18) et d'autre part par au moins une partie de blocage dans l'alésage de palier. Afin d'obtenir une fixation de palier économique et facile à monter, il est proposé de fixer le roulement à billes (16) en direction axiale au moyen d'au moins une goupille d'ajustement (22) servant de pièce de blocage qui traverse l'alésage de palier (18) en forme de corde et qui est fixée dans le carter (14) de la boîte de vitesses, au moins un élément élastique (21) étant placé sur une face du roulement à billes (16) afin de compenser les tolérances.
