Motor shell with high sealing performance

Abstract

The utility model discloses a motor casing with high sealing performance, which belongs to the technical field of motor casings and comprises a cylindrical casing, a front end plate is arranged at the front end of the cylindrical casing, a rear cover seat and a closed cylinder are connected to the rear end of the cylindrical casing through bolts, the closed cylinder is detachably mounted on the front end plate, a sealing ring and a sealing performance monitoring ring are mounted in the closed cylinder, and the sealing performance monitoring ring is arranged on the outer side of the closed cylinder. The sealing ring is used for monitoring whether the sealing performance of the sealing ring fails or not and comprises a rubber ring body, and a plurality of inclined water blocking rings are arranged on the inner wall of the rubber ring body. According to the technical scheme, during installation, the motor output shaft is attached to the inclined water blocking ring, the inclined water blocking ring inclines and deforms outwards under the extrusion effect, multiple water blocking defense lines are formed, and the anti-seepage performance of the connecting position of the motor output shaft and the motor shell is remarkably improved; the sealing performance monitoring ring can monitor the condition in time and remind maintenance workers of failure of the sealing performance at the joint through color change, and the maintenance workers are warned to pay attention to timely maintenance.
