Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, those skilled in the art is made to become apparent from
How ground understanding puts into practice the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
As shown in Figure 1, a kind of fixed structure for disk type electric machine stator, the fixed structure be used for by stator winding disk with
Electric machine casing is fixedly connected, and difference with the prior art is, stator winding disk, motor casing are equipped in the electric machine casing
Resin layer is equipped between body and stator winding disk；Electric machine casing includes lateral surface and medial surface, is deposited between lateral surface and medial surface
In cavity, medial surface is equipped with the embedding hole being recessed inwardly, and when to embedding, resin directly pours into winding disk and electricity in embedding hole
Casing body forms an entirety, and the resin layer formed after embedding can firmly combine closely electric machine casing and stator winding disk, this
In resin layer it is unfixed only with face layer, i.e., the medial surface of resin layer is fixed with lateral surface and connected object, more using depth
Enter method to be fixed, it refers to forming the hold-down bars for being deeply connected inner using connected object surface groove to go deep into method just
Connection method, since the utility model uses both modes simultaneously, linking is better.
Specifically, polymer matrix composites imbed in shrinkage pool, and entire winding disk and the resin base for coating winding disk are compound
Material forms the entirety of gear-like, and the entirety is fitted closely with motor housing, effectively prevent motor stator whole outside motor
It skids and rotates around axis in shell, to improve electric machine structure intensity.
In one embodiment, the embedding hole is cylindrical recess hole, and embedding hole is one group two-by-two and is evenly distributed on
The surface of medial surface, each group of embedding hole are arranged in parallel in the surface of medial surface up and down, and each group of embedding hole can be flat here
Row setting, or further strengthen firmness, prevent from being damaged because of high-speed rotation when using, can make each group
Two embedding holes between shape in an angle, included angle be 5-15 degree；The depth in embedding hole be medial surface and lateral surface it
Between distance 1/3-1/2, can guarantee certain deep-going in this way, improve the fastness of combination.
When embedding, this patent is before stator winding disk is placed in embedding tooling and motor housing, first in tooling resin
The medial surface of contact surface and electric machine casing is laid with glass fibre prepreg or glass mat, then embedding, is formed after curing in this way
Polymer matrix composites clad, corrosion resistance is strong, and structural strength is high, effectively prevent simple resin embedding layer to crack, hits
It smashes and splits.
Meanwhile embedding uses vacuum encapsulation, and motor housing and embedding tooling one are assembled, and is laid with glass fiber, fiber
Felt or resin-base glass fibre prepreg, put stator winding disk, re-lay another layer of glass fiber, fibrofelt or tree
Aliphatic radical glass fibre prepreg, assembly embedding tooling two.Fluid sealant etc. is pasted, closed chamber is formed.Vacuum extractor is opened, at one section
Between, reach predetermined vacuum degree.Close vacuum extractor, open resin glue-feeder, until resin fills entire closed chamber, close into
Jiao Kou.Heating is until resin solidification.Tooling is removed, part post-processes.
