Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor housing structure convenient for oil injection. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. They are widely used in various equipment and systems, from household appliances such as refrigerators and washing machines to industrial machinery and automobiles. The working principle of a motor is based on the law of electromagnetic induction. When an electric current passes through a conductor, a magnetic field is generated, and this magnetic field interacts with a fixed magnetic field to generate torque, driving the motor to rotate.

[0003] Motor oil injection is an important step in the maintenance process. It refers to the process of adding lubricating oil or grease to the bearings or other components that need lubrication inside the motor. Proper lubrication can reduce friction, reduce wear, improve efficiency, and ultimately extend the service life of the motor.

[0004] After the existing motors run for a certain period of time, it is necessary to inject oil to lubricate the bearings on the rotating shafts inside the motors; however, both ends of the rotating shafts of the existing motors are sealed by a front end cover and a rear end cover, and bolts are used for fixation. When injecting oil, it is necessary to remove the front end cover and the rear end cover of the motor, and after the oil injection is completed, the front end cover and the rear end cover need to be reinstalled. The oil injection process is relatively complicated and also affects the oil injection efficiency. Therefore, in order to solve the above technical problems, this application proposes a motor housing structure convenient for oil injection. Content of the Utility Model
