Description

Technical Field

[0001] The utility model specifically relates to the technical field of sealed motors, in particular to a protective sealed motor. Background Art

[0002] Electric machinery (commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines; while the motor box is a box used to fix the motor.

[0003] At present, when traditional motors are assembled and sealed, they are simply matched with rubber gaskets. After long-term use, the gaskets will age, harden and crack. In this way, the rubber gaskets cannot effectively achieve the sealing effect at the motor connection, causing the motor to leak internally in different usage scenarios.

[0004] After searching, Chinese patent publication number CN202222640323.X discloses a motor sealing structure and a motor; including a front end cover and an output shaft passing through the front end cover, an outer end surface of the front end cover is provided with an embedding groove, the embedding groove is coaxially arranged with the output shaft, a skeleton oil seal is provided in the embedding groove, and the outer periphery of the skeleton oil seal is tightly pressed against the inner wall of the embedding groove;

[0005] When the structure in the above patent is used to seal the motor, the inner wall of the skeleton oil seal is pressed against the outer periphery of the output shaft and the outer periphery of the skeleton oil seal is pressed against the casing to form a motor sealing structure. The structure in the above patent can only achieve the sealing between the output shaft and the casing, and cannot effectively achieve the sealing of the entire motor. When the motor leaks from the edge connection position of the casing during long-term use, it will also affect the operation of the motor.

[0006] In view of the above situation, we provide a protective sealed motor. In this device, a first plug-in ring and a second plug-in ring are respectively provided at both ends of the shell, and the first plug-in ring cooperates with the second slot opened on the second sealing cover, and the second plug-in ring fits with the slot on the first sealing cover, and then the rear end cover and the front end cover are matched by a screw to fix the sealing shell. The rotor is installed by the bearing and the bearing mounting seat inside the second sealing cover, and is equipped with a rubber sealing ring. In this way, during long-term use, the sealing of the inside of the sealing shell can be effectively guaranteed to prevent external moisture from penetrating into the shell. Utility Model Content
