The invention relates to a method for mounting the rotor (22) of an external rotor motor (20) on a bearing support tube (70) and in a predetermined axial position relative thereto, said rotor (22) comprising a rotor bell (24) and a rotor shaft (28). The inventive method comprises the following steps: a) starting from the rotor bell (28), a compression spring (48), a lock washer (50) and a bearing system with a plurality of antifriction bearings (52, 60) is mounted on the rotor shaft (28), the inner raceways (56, 64) of the antifriction bearings being displaceably mounted on the rotor shaft (28) so as to slide within a predetermined range; b) the rotor (24) with the elements mounted thereon is pressed into the bearing support tube (70) by means of a compression force (K), whereby the compression spring (48) is compressed to such an extent that the rotor bell presses the lock washer (50) into the bearing support tube (70); c) the compression force (K) is removed and the rotor shaft (28) is displaced by means of the compression spring (48) in the inner raceways (56, 64) of the bearings (52, 60) to such an extent that the rotor (24) assumes the predetermined axial position relative to the bearing support tube (70).

La présente invention concerne un procédé pour monter le rotor (22) d'un moteur à induit extérieur (20) sur un tube support de palier (70) et dans une position axiale prédéfinie par rapport à celui-ci. Le rotor (22) présente une cloche de rotor (24) et un arbre de rotor (28). Le procédé consiste, a) en commençant avec la cloche de rotor (24), à appliquer sur l'arbre de rotor (28) un ressort de pression (48), une rondelle de sécurité (50) et un ensemble de palier présentant une pluralité de paliers à roulement (52, 60), les bagues intérieures (56, 64) des paliers à roulement pouvant glisser sur l'arbre de rotor (28) sur un domaine prédéfini, b) à enfoncer le rotor (24) avec les éléments qui y sont fixés dans le tube support de palier (70) au moyen d'une force d'enfoncement (K), le ressort de pression (48) étant conjointement comprimé, de façon que la cloche de rotor enfonce la rondelle de sécurité (50) dans le tube support de palier (70), c) à supprimer la force d'enfoncement (K), puis à déplacer l'arbre de rotor (28) dans les bagues intérieures (56, 64) des paliers (52, 60), de façon que le rotor (24) adopte la position axiale prédéfinie par rapport au tube support de palier (70).
