Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to an assembly structure for a motor box body and a box cover. Background Art

[0002] As the core equipment in modern industry, the operation stability and service life of the motor are of great significance to industrial production. As the key part of the motor reducer, the design and manufacturing quality of the motor case cover assembly structure directly affect the overall performance of the motor. The traditional motor case cover assembly structure is usually fixed by bolting or welding, but these methods have many shortcomings. Bolted connections require additional fasteners and installation space, and are easily affected by vibration and temperature changes, resulting in loose connections or failure. The welding method is difficult to ensure the sealing and reliability of the connection, and is difficult to operate during maintenance and replacement.

[0003] Therefore, it is necessary to design a new motor case cover assembly structure to solve the above problems and improve the running stability and service life of the motor. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an assembly structure for a motor case cover.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: an assembly structure for a motor case cover, comprising: a case and a cover, one end of the cover is inserted into the case, hooks are equidistantly installed on the cover, the hooks are arranged on the outer wall of the connection between the cover and the case, a limiting ring and a retaining ring are fixedly arranged on the case, the limiting ring and the retaining ring are arranged on the outer side of the connection between the case and the cover, a groove is provided inside the limiting ring and the retaining ring corresponding to the hook, the hook can be inserted into the groove from the connecting end of the case, a hoop groove is formed between the limiting ring and the retaining ring, a clamp is installed in the hoop groove, and the clamp is used to clamp the protrusion of the hook to fix it.

[0006] As a preferred solution of the utility model, the limiting ring is provided with an open groove, and the open groove is used for removing the clamp.

[0007] As a preferred solution of the utility model, the hooks and slots are correspondingly arranged in eight groups.

[0008] As a preferred solution of the utility model, the assembly structure is formed by injection molding.

[0009] As a preferred solution of the present utility model, the clamp 7 is an elastic throat clamp with a diameter of 2.50 mm.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0011] The utility model realizes a quick and stable connection between the motor case and the case cover by adopting an assembly method of hooks and slots, thereby reducing the difficulty and cost of assembly. At the same time, the fixing effect of the clamp further enhances the stability and reliability of the connection, effectively preventing the loosening or failure of the connection caused by vibration and temperature changes. In addition, the open groove design on the limit ring makes the disassembly operation more convenient and improves the maintenance efficiency. The utility model improves the operating stability and service life of the motor, reduces the maintenance cost, and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
