The utility model discloses a stator and casing fixed knot construct and newly increase the keyway on stator core and casing, thereby the keyway intussuseption is filled epoxy and is formed the epoxy key, has strengthened the cooperation between casing and the stator core, is applicable to and solves the untight problem of stator core and casing cooperation.
Description
Technical Field
The utility model belongs to the technical field of the motor, concretely relates to stator and casing fixed knot construct based on irritate epoxy.
Background
In the stator assembly of the motor, the embedded wire stator and the shell are assembled in a shrink fit mode, and occasionally, a product with small interference occurs in the production process. Stator module is difficult to inspect after the hot jacket is accomplished whether the magnitude of interference is enough, and the defective work receives the magnetic force influence of magnet steel in the rotor at motor moving in-process, can appear beating the phenomenon of changeing between rule stator and the casing, and the rule stator module that the rule stator appears beating the commentaries on classics can be unable to be used, needs to change the rule stator.
Disclosure of Invention
The utility model aims to solve the technical problem that not enough provide a stator and casing fixed knot construct based on irritate epoxy to above-mentioned prior art, this stator and casing fixed knot construct based on irritate epoxy increase the keyway on stator core and casing newly, thereby the keyway intussuseption is filled epoxy and is formed the epoxy key, has strengthened the cooperation between casing and the stator core, is applicable to and solves the untight problem of stator core and casing cooperation.
In order to realize the technical purpose, the utility model discloses the technical scheme who takes does:
the utility model provides a stator and casing fixed knot construct based on irritate epoxy, includes rule stator and casing, the rule stator includes stator core and coil, thereby the winding inslot of stator core has the coil to form the rule stator, stator core's outside cover is equipped with the casing, the inner wall of casing is equipped with a plurality of keyways along axial extension, stator core's outer disc is equipped with a plurality of keyways along axial extension, all fill in all keyways around the coil and have the epoxy.
As a further improved technical scheme of the utility model, the casing is established in stator core's outside through hot jacket mode cover.
As a further improved technical scheme of the utility model, the coil adopts copper line coil.
The utility model has the advantages that: the utility model discloses a newly-increased epoxy key on stator core and casing strengthens the cooperation between casing and the stator core. The structure is not changed greatly, and the stator core and the shell are not tightly matched.

Detailed Description
The following further description of the embodiments of the present invention is made with reference to the accompanying fig. 1:
in the design of a high-speed permanent magnet motor, the embedded wire stator and the shell cannot rotate, so the embedded wire stator is matched with the shell in an interference fit mode, and in order to enable the shell to be matched with the embedded wire stator more firmly, a certain number of key grooves are additionally arranged on the shell and the embedded wire stator, and epoxy is filled in the key grooves to form epoxy keys. The method comprises the following specific steps:
the utility model provides a stator and casing fixed knot construct based on irritate epoxy, includes rule stator and casing 3, as shown in figure 1, the rule stator includes stator core 1 and coil 2, casing 3 overlaps through the shrink fit mode and establishes the outside at stator core 1. A certain number of winding grooves are formed in the inner diameter of the stator core 1, and a certain number of axially extending key grooves 5 are formed in the outer diameter (i.e., the outer circumferential surface). A coil 2 is wound in a winding slot of the stator core 1 to form a wired stator. A certain number of key grooves 5 extending along the axial direction are processed on the inner diameter of the position where the stator core 1 is assembled on the shell 3; the surroundings of the coil 2 and all the keyways 5 are filled with epoxy 4, and the keyways 5 are filled with epoxy 4 to form epoxy keys.
The copper wire coil 2 is wound in the winding groove to form a coil inserting stator, the coil inserting stator is assembled in the shell 3 in a shrink fit mode, and the coil inserting stator is packaged into an integral structure through epoxy filling. The keyways 5 processed on the stator core 1 and the shell 3 allow epoxy to flow in when epoxy is poured, so that an epoxy key is formed, and the matching between the stator core 1 and the shell 3 is further enhanced.
Firstly, winding a coil 2 in a winding groove of a stator core 1, then heating a shell 3, assembling the stator core 1 in the shell 3 before cooling after heating, and finally pouring epoxy into the stator, wherein the epoxy can enter a key groove 5 of the stator core 1 and the shell 3 to form an epoxy key.
In this embodiment, epoxy keys are additionally added to the stator core 1 and the housing 3 to enhance the fit between the housing 3 and the stator core 1. The structure is not changed greatly, the newly added steps and the processes are simple, and the stator core assembling method is suitable for solving the problem that the stator core 1 and the shell 3 are not tightly matched.
The protection scope of the present invention includes but is not limited to the above embodiments, the protection scope of the present invention is subject to the claims, and any replacement, deformation, and improvement that can be easily conceived by those skilled in the art made by the present technology all fall into the protection scope of the present invention.
