Motor, sealing ring for same and air conditioner provided with same

Abstract

The invention discloses a motor, a sealing ring for the motor and an air conditioner provided with the motor. The motor comprises a shell body, a rotation shaft, at least one sealing ring and a waterproof cover, wherein a cavity is formed inside the shell body in a limited mode, open end ports are formed in the two ends of the shell body respectively, the rotation shaft penetrates through the end ports in the two ends of the shell body, the sealing ring is arranged on one end port of the shell body, seals the corresponding end of the shell body and is annular, a water-blocking plate extending inwards in the radial direction is arranged on the inner wall face of the sealing ring and is provided with a receding hole where the rotation shaft is not located, the waterproof cover is arranged on the rotation shaft in a sleeved mode and located inside the sealing ring, and the radial dimension of the waterproof cover is larger than the radial dimension of the receding hole. According to the motor, the waterproof cover can be installed between the inner wall face of the sealing ring and the outer wall face of the rotation shaft, so that the motor is more compact in overall structure, is convenient to assemble, meets various requirements of users, and has a good waterproof effect.

Description

technical field [0001] The present invention relates to the technical field of motors, and more specifically, to a motor, a sealing ring for the motor and an air conditioner with the motor. Background technique [0002] The existing waterproof structure of the motor adopts the method of adding a waterproof cover and other components on the motor end cover and the rotor shaft. For the motor installed with the anti-vibration rubber ring, due to the compact structure, the existing structure cannot meet the requirements. The existing technology provides a new type of waterproof structure for motors. The waterproof cover is arranged outside the motor end cover and cooperates with the end cover. For customer loads, the installation structure of vibration damping rings at both ends cannot meet the requirements of use, and the waterproof effect is limited. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least ...

AI Technical Summary

Problems solved by technology

[0002] The existing motor waterproof structure adopts the method of adding waterproof cover and other components on the motor end cover and rotor shaft. For the motor installed with anti-vibration rubber ring, the existing structure cannot meet the requirements due to its compact structure.

The existing technology provides a new type of waterproof structure for motors. The waterproof cover is arranged outside the motor end cover and cooperates with the end cover. For customer loads, the installation structure of vibration damping rings at both ends cannot meet the requirements of use, and the waterproof effect is limited.
