Title (EN) VACUUM PUMP
(FR) POMPE À VIDE
(JA) 真空ポンプ
Abstract:
(EN) The vacuum pump according to one embodiment of the present invention is provided with a first unit and a second unit. The first unit has a rotor core, a first rotating shaft, which supports the rotor core, and which extends in one axis direction, and a pump housing that houses the first rotating shaft therein. The second unit has a cylindrical member, a stator core, a motor housing, a seal ring, and a regulation member. The cylindrical member has an open end section and a closed end section, and houses the rotor core therein. The stator core is disposed around the cylindrical member. The motor housing houses the cylindrical member and the stator core therein, and is connected to the pump housing. The seal ring is disposed between the cylindrical member and the motor housing. The regulation member is attached to the motor housing, and faces, in the one axis direction, the open end section of the cylindrical member.
(FR) La pompe à vide selon un mode de réalisation de la présente invention est pourvue d’une première unité et d’une seconde unité. La première unité a un noyau de rotor, un premier arbre rotatif, qui soutient le noyau de rotor, et qui s'étend dans une direction d'axe, et un carter de pompe qui loge le premier arbre rotatif en son sein. La seconde unité a un élément cylindrique, un noyau de stator, un carter de moteur, une bague d'étanchéité et un élément de régulation. L'élément cylindrique a une section d'extrémité ouverte et une section d'extrémité fermée, et loge le noyau de rotor en son sein. Le noyau de stator est disposé autour de l'élément cylindrique. Le carter de moteur loge l'élément cylindrique et le noyau de stator en son sein, et est relié au carter de pompe. La bague d'étanchéité est disposée entre l'élément cylindrique et le carter de moteur. L'élément de régulation est fixé au carter de moteur, et fait face, dans la direction d'axe, à la section d'extrémité ouverte de l'élément cylindrique.
(JA) 本発明の一形態に係る真空ポンプは、第１のユニットと、第２のユニットとを具備する。第１のユニットは、ロータコアと、ロータコアを支持し一軸方向に延びる第１の回転軸と、第１の回転軸を収容するポンプハウジングと、を有する。第２のユニットは、円筒部材と、ステータコアと、モータハウジングと、シールリングと、規制部材とを有する。円筒部材は、開口端部と閉塞端部とを有し、ロータコアを収容する。ステータコアは、円筒部材の周囲に配置される。モータハウジングは、円筒部材とステータコアとを収容し、ポンプハウジングに結合される。シールリングは、円筒部材とモータハウジングとの間に配置される。規制部材は、モータハウジングに取り付けられ、円筒部材の開口端部と上記一軸方向に対向する。
