Title
(EN) HOLLOW-SHAFT ELECTRIC MOTOR
(FR) MOTEUR ÉLECTRIQUE À ARBRE CREUX
(ZH) 一种空心轴电机
Abstract
(EN) The present invention provides a hollow-shaft electric motor, comprising a rotor (1), a stator (6), a housing (7), and a hollow shaft (3); the stator (6) is sleeved outside the rotor (1) and fixed in the housing (7); the rotor (1) is sleeved outside the hollow shaft (3) and fixedly connected to the hollow shaft (3); at least one end of the hollow shaft (3) is detachably connected to a connecting member (2) used for connecting to a load device. In the present invention, the hollow shaft is connected to the load device by means of the connecting member rather than directly connecting the hollow shaft to the load device, thus wear on the hollow shaft is prevented; since the connecting member and the hollow shaft are connected by means of a detachable connection, after the connecting member wears out, one must simply remove the connecting member and replace it with a new one; disassembly and maintenance are convenient, reducing maintenance costs.
(FR) La présente invention concerne un moteur électrique à arbre creux, comprenant un rotor (1), un stator (6), un boîtier (7), et un arbre creux (3) ; le stator (6) est emmanché à l'extérieur du rotor (1) et fixé dans le boîtier (7) ; le rotor (1) est emmanché à l'extérieur de l'arbre creux (3) et relié à demeure à l'arbre creux (3) ; au moins une extrémité de l'arbre creux (3) est reliée de façon détachable à un élément de liaison (2) utilisé pour être relié à un dispositif de charge. Dans la présente invention, l'arbre creux est relié au dispositif de charge au moyen de l'élément de liaison plutôt que de relier directement l'arbre creux au dispositif de charge, ainsi l'usure sur l'arbre creux est évitée ; étant donné que l'élément de liaison et l'arbre creux sont reliés au moyen d'une liaison détachable, après que l'élément de liaison s'est usé, on doit simplement retirer l'élément de liaison et le remplacer par un nouveau ; le démontage et l'entretien sont pratiques, réduisant les coûts d'entretien.
(ZH) 本发明提供了一种空心轴电机,其包括转子(1)、定子(6)、外壳(7)和空心轴(3),定子(6)套在转子(1)外,并固定在外壳(7)内,转子(1)套在空心轴(3)外,并与空心轴(3)固定连接,空心轴(3)的至少一端可拆卸地连接有用于连接负载设备的连接件(2)。本发明将空心轴通过连接件与负载设备连接,而不直接将空心轴与负载设备连接,能避免空心轴发生磨损,由于连接件与空心轴通过可拆卸连接的方式连接,在连接件发生磨损后,将连接件拆卸下来更换一个新的连接件即可,拆装、维修方便,降低维修成本。
