Problems solved by technology

The stamping riveting process will cause damage to the motor end cover, thereby reducing the service life of the end cover
[0003] The motor end cover and the casing are clearance fit or interference fit. The clearance fit cannot eliminate the concentricity, and the pressing force is too large, which makes it difficult to assemble, resulting in serious deformation of the front and rear of the end cover and the casing.
Transition fit, either loose or tight, is difficult to achieve the desired effect

Abstract

The invention belongs to the motor manufacturing technology field, and especially relates to a motor. The motor comprises a housing. A carbon brush holder mechanism, a commutator, a stator and a rotor are arranged in the housing. The rotor comprises a rotating shaft arranged in the housing. A rotor chip is arranged outside the rotating shaft. The rotor is provided with coils, and the coils are connected with the carbon brush holder mechanism through the commutator. A sawtooth structure is adopted to be in interference fit with the housing, thereby eliminating a gap between an end cap and the housing, and ensuring that the front and the rear of the end cap and the housing will not deform seriously. The inner rim and the outer rim of a cylindrical end cap bearing clamp are bent inwardly at the same time, and the circumference of the inner rim is evenly provided with multiple grooves, so that elastic deformation occurs during insertion, assembling is easy, and locking is firm. Therefore, the motor has a simple structure, is convenient to implement, and helps to prolong the service life of the end cap.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a motor. Background technique [0002] In the existing motor end cover structure, the end cover and the bearing are riveted together by stamping. The stamping riveting process will cause damage to the motor end cover, thereby reducing the service life of the end cover. [0003] The motor end cover and the casing are clearance fit or interference fit. The clearance fit cannot eliminate the concentricity, and the pressing force is too large, which makes it difficult to assemble, resulting in serious deformation of the front and rear of the end cover and the casing. Transition fit, either loose or tight, is difficult to achieve the desired effect. [0004] Therefore, it is of great significance to study and design a motor end cover structure that is simple in structure, convenient to implement, and has a long service life. Contents of the invention [00...
