CN-224204829-U - Motor stator sealing structure

Abstract

The utility model discloses a motor stator sealing structure which comprises a stator body, wherein a sealing cylinder is inserted into an inner hole of the stator body in a fitting mode, and the sealing cylinder and the stator body are encapsulated into a whole. In the motor stator sealing structure, the sealing cylinder is arranged in the inner hole of the stator body, so that the motor stator and the inside of the cavity can be effectively isolated, and a sealing mode is formed. At this time, the sealing of the motor stator is completed by the sealing cylinder, and the pouring sealant only plays a role in supporting and bonding the sealing cylinder, so that even if fine air holes exist during pouring, sealing failure can not be caused. And moreover, the sealing cylinder and the motor stator are integrally formed, so that the space occupation can be saved, and the whole volume of the equipment is reduced.

Description

Motor stator sealing structure Technical Field The present disclosure relates to motor structures, and particularly to a motor stator sealing structure. Background In the prior art, the sealing of the motor stator mainly adopts a pouring sealant form. Such a motor stator sealing method cannot achieve an effective stator seal because of problems such as easy cracking, fine air holes, and easy reaction with a medium. Particularly under the condition of high pressure or vacuum, the sealing form of the pouring sealant is extremely easy to lose efficacy, thereby influencing the normal production and use of the motor. Disclosure of utility model The utility model provides a motor stator sealing structure aiming at the defects of the prior art. The motor stator sealing structure comprises a stator body, wherein a sealing cylinder is inserted into an inner hole of the stator body in a fitting mode, and the sealing cylinder and the stator body are encapsulated into a whole. In the motor stator sealing structure, the sealing cylinder comprises a cylinder body, and an inward extending cylinder edge and an outward extending cylinder edge which extend inwards are respectively integrally formed at two ends of the cylinder body. In the motor stator sealing structure, the outer side wall of the cylinder body is provided with the axial positioning step which is correspondingly matched with the inner hole of the stator body. In the motor stator sealing structure, the end sealing ring groove is formed in the end face of the extension cylinder edge, and the end elastic sealing ring is arranged in the end sealing ring groove. In the motor stator sealing structure, the outer edge of the extension cylinder is provided with an outer edge sealing ring groove, and an outer edge elastic sealing ring is arranged in the outer edge sealing ring groove. In the motor stator sealing structure, the inner edge of the outer extension cylinder edge is provided with the inner edge sealing ring groove, and the inner edge sealing ring groove is internally provided with the inner edge elastic sealing ring. In the motor stator sealing structure, the end face of the inner extension tube edge is provided with the end sealing ring groove, and the end elastic sealing ring is arranged in the end sealing ring groove. In the motor stator sealing structure, the inner edge of the inner extension tube edge is provided with an inner edge sealing ring groove, and an inner edge elastic sealing ring is arranged in the inner edge sealing ring groove. In the motor stator sealing structure, the outer edge of the inner extension tube edge is provided with an outer edge sealing ring groove, and an outer edge elastic sealing ring is arranged in the outer edge sealing ring groove. In the motor stator sealing structure, the sealing cylinder is arranged in the inner hole of the stator body, so that the motor stator and the inside of the cavity can be effectively isolated, and a sealing mode is formed. At this time, the sealing of the motor stator is completed by the sealing cylinder, and the pouring sealant only plays a role in supporting and bonding the sealing cylinder, so that even if fine air holes exist during pouring, sealing failure can not be caused. And moreover, the sealing cylinder and the motor stator are integrally formed, so that the space occupation can be saved, and the whole volume of the equipment is reduced.
