In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides a seal structure of motor, includes end cover, bearing and motor shaft, the motor shaft passes in proper order end cover and bearing, still includes seal assembly, the shaft hole has been seted up on one of them side of end cover, seal assembly sets up in the shaft hole, just the motor shaft passes seal assembly.
Through installing seal assembly in the shaft hole, not only strengthened the structural strength of end cover, still promoted the sealing performance of motor, and still be convenient for seal assembly's installation, change and maintenance.
Preferably, in the above-mentioned sealing structure of a motor, the sealing assembly includes an oil seal and a sealing ring, and the oil seal and the sealing ring are sequentially disposed in the shaft hole.
The sealing performance of the motor shaft can be further enhanced by the cooperation of the oil seal and the sealing ring.
Preferably, in the sealing structure of a motor, a first mounting groove and a second mounting groove are formed in the shaft hole, the oil seal is arranged in the first mounting groove, and the sealing ring is arranged in the second mounting groove.
The arrangement of the first mounting groove and the second mounting groove enables the installation of the oil seal and the sealing ring to be more stable, and the maintenance is convenient.
Preferably, the sealing structure of a motor further includes a sealing ring base, the sealing ring base is disposed in the second mounting groove, and the sealing ring is disposed on the sealing ring base.
The setting of sealing washer base is convenient for the installation of sealing washer.
Preferably, the sealing structure of a motor further comprises a clamp spring, wherein the clamp spring is arranged on the outer side of the sealing ring.
The arrangement of the clamp spring enables the installation of the sealing ring to be more stable.
Preferably, in the sealing structure of a motor, a mounting groove is further formed in one side, facing away from the shaft hole, of the end cover, and the bearing is arranged in the mounting groove.
The installation groove is convenient for the installation, maintenance and replacement of the bearing, and the bearing can be operated more stably.
