Title (EN) ROTOR FOR BUILT-IN MOTOR
(FR) ROTOR POUR MOTEUR INCORPORE
Abstract:
(EN) A rotor for a built-in motor which permits a core to be easily removed from the shaft. It comprises a shaft (1) having a stepped portion (11); a sleeve (2) having a hollow portion (21) that is arranged to cover the stepped portion (11) and having a hydraulic pressure supply hole (22) communicating with the hollow portion (21), the sleeve (2) being fitted to the shaft (1) that has the stepped portion (11); and a core (3) fitted onto the sleeve (2).
(FR) Un rotor pour un moteur incorporé permet d'enlever aisément le noyau de l'arbre. Ce rotor comprend un arbre (1) ayant une partie échelonnée (11); un manchon (2) a une partie creuse (21) qui recouvre la partie échelonnée (11) et un orifice d'alimentation en pression hydraulique (2) en communication avec la partie creuse (21), le manchon (2) étant adapté à l'arbre (1) ayant la partie échelonnée. Un noyau (3) est adapté sur le manchon (2).
