Embodiment Construction

[0047] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0048] like figure 1 As shown, a segmented motor stator housing based on a mechanical model according to the present invention includes a stator 4 and a housing 1 . The casing 1 is designed in blocks instead of a traditional integral structure, and includes a left half shell 11 and a right half shell 12 . like figure 2 As shown, one end of the left half-shell 11 is provided with a bolt fixing seat A13, and the other end is provided with a bolt fixing seat B14. The bolt fixing seat A13 and the bolt fixing seat B14 are mirror images corresponding to each other. The left half-shell 11 has an integrated structure and is used for matching installation. Equally, one end of right half-shell 12 is provided with bolt fixing seat C15, and t...

Abstract

The invention relates to a segment type motor stator housing based on a mechanical model and an assembling design method thereof, thus solving the problems that an existing shrinkage fit technology has inconveniences in stator and housing installations; one end of the left half housing is provided with a bolt fixed seat A, the other end is provided with a bolt fixed seat B, and A and B are in mirror arrangement; one end of the right half housing is provided with a bolt fixed seat C, the other end is provided with a bolt fixed seat D, and C and D are in mirror arrangement; the left and right half housings are matched so as to clamp the outer side of the stator, and are in mirror arraignment; a left bolt is arranged on the bolt fixed seats A and C; a right bolt is arranged on the bolt fixed seats B and D. The segment type motor housing design is realized; the bolts can fix and mount the left and right half housings, thus greatly simplifying the motor stator housing assembling process.

Description

technical field [0001] The invention relates to the technical field of motor stator housings, in particular to a mechanical model-based segmented motor stator housing and an assembly design method thereof. Background technique [0002] With the rapid development of the electric vehicle industry, related technologies are also constantly improving. As the core component of electric vehicles, permanent magnet synchronous motors directly determine the performance of electric vehicles. At present, the permanent magnet synchronous motor stator and shell in the field of new energy vehicles are mainly assembled through the shrink-fit process, that is, the motor shell is heated to expand the shell and the inner diameter, and then the stator is installed. , the inner diameter of the housing decreases rapidly, and the interference between the stator and the housing is used to ensure that the relative displacement does not occur between the two. [0003] Adopting this kind of assembly ...
