AI Technical Summary
Technical Problem
The sealing ring deforms due to the complex environment during long-term use, resulting in a decrease in the waterproof performance of the motor.
Method used
The design employs a guide rod and a return spring to ensure precise installation of the sealing ring. The elastic deformation of the return spring provides continuous contact pressure, compensating for the reduction in sealing force caused by aging, wear, and thermal expansion and contraction of the sealing ring.
Benefits of technology
It improves the effective lifespan of the sealing mechanism, maintains the long-term stability of the sealing effect, and prevents external moisture and dust from entering.

Abstract
The application discloses a waterproof sealed aluminum shell and belongs to the technical field of motor waterproof sealing. The waterproof sealed aluminum shell comprises a shell body and a rotor arranged in the shell body. A shaft rod is arranged on the rotor. A bearing is arranged at the rear end of the shaft rod. A rear end cover for assembling the shaft is arranged at the rear end of the shell body. A sealing mechanism and a rear bearing cover connected with the sealing mechanism are arranged on the outer side of the rear end cover. The shaft rod penetrates the bearing, the rear end cover, the sealing mechanism and the rear bearing cover in sequence. A fan blade is sleeved with one end of the shaft rod. A fan cover is arranged at the tail end of the shell body. The guide rod and the sealing ring are arranged in the waterproof cylinder shell. The guide rod ensures the accurate installation position of the sealing ring and limits the displacement direction of the sealing ring in the limiting groove. The reset spring is sleeved with the guide rod. The sealing ring is continuously pressed close to the rear bearing cover. The sealing force attenuation caused by aging and abrasion of the sealing ring is compensated. The effective service life of the sealing mechanism is improved.
