Motor casing

Abstract

The case is related to case, case cover, and first skidresisting lobes. Room for housing fixer and rotor is formed in the cylindrical case including an opening part on side. The case cover in plated surface shape covers the opening part on side of the case body. Mutual staggered arranged multiple first skidresisting lobes are made on the plated surface of the case cover along peripheral direction with certain distance. Based on the said structure, sliding between the case cover and case body will not be generated. Fast and handy machining and assembling reduces manufacturing cost.

Description

technical field [0001] The invention relates to a casing of a motor in the electrical field, in particular to a casing of a motor capable of simple and quick processing and assembly. Background technique [0002] Please refer to Fig. 1 to Fig. 3, Fig. 1 is a practical structure diagram of the existing motor casing, Fig. 2 is a front view of the case cover in Fig. 1, and Fig. 3 is a cross-sectional view of Fig. 2 . As shown in the figure, a general motor is composed of the following parts: a housing space with a fixer 11 and a rotor 13 is formed inside; a rotatable rotor 13 located inside the fixer 11 and centered on the rotating shaft 15 is housed and installed; Around the holder 11 and the rotor 13, a casing 21 supporting the two parts can be accommodated. [0003] The above-mentioned casing 21 is composed of the following parts: a casing main body 22 with cylindrical shape on both sides and forming a storage space inside; a casing cover that covers the opening areas on bo...

AI Technical Summary

Problems solved by technology

[0007] However, in conventional motor casings, since each casing cover is made by die-casting aluminum, not only the manufacturing time is long, but also the cost is high.

In addition, the outer diameter surface of the insertion portion 26 inserted into the casing body 22 around the casing cover 23 and the joint portion 24 of the two openings of the casing body 22 into which the insertion portion 26 is inserted need to be machined. Processing time and energy, but also greatly increase the overall production cost

[0008] Since the insertion part 26 of each case cover 23 and the inner diameter surface of the case main body 22 are in full contact along the peripheral direction, depending on the insertion direction and position, there may be installation problems such as difficulty in insertion or severe deviation after installation.

[0009] This shows that above-mentioned existing motor casing still has many defectives, and needs to be further improved urgently
