Abstract
The utility model discloses a kind of impeller body assembly, including integrally formed bottom plate and base sleeve, bearing is provided in the base sleeve, described bearing one end is provided with hole for injecting glue.The impeller body assembly of the structure in rotation process, can improve balance and stability.
Description
Technical field
The utility model is related to electronic water pump fields, and in particular to a kind of impeller body assembly.
Background technology
At present new energy vehicle electric drive cooling end grade field mostly use brushless electronic water pump provided for cooling cycle it is dynamic
Power, brushless water pump have many advantages, such as long lifespan, efficient.Current electronic water pump impeller body assembly, including bottom plate, setting are the bottom of at
The base sleeve of plate side and the bearing being arranged in base sleeve, the bottom plate and base sleeve integrated injection molding, bearing are fixed with base sleeve
Bearing is mounted in fixing axle by connection, you can so that impeller body assembly is relatively fixed shaft rotation dynamic.
In the prior art, easily relatively rotate between bearing and base sleeve, to influence impeller body assembly balance and
Stability.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of impeller body assembly, in rotation process, balance can be improved
And stability.
The utility model is solved the above problems by following technological means：A kind of impeller body assembly, including it is integrally formed
Bottom plate and base sleeve are provided with bearing in the base sleeve, and described bearing one end is provided with hole for injecting glue.
Further, described bearing one end is symmetrical arranged about bearing centre there are two hole for injecting glue, and the hole for injecting glue runs through axis
Hold wall.
Further, the bearing outer wall, which is inlayed, is provided with multiple memorial alloy bodies, and base sleeve inner wall corresponds to each memorial alloy
The position of body is both provided with groove.
The beneficial effects of the utility model：The impeller body assembly of the utility model, including integrally formed bottom plate and base sleeve,
Bearing is provided in the base sleeve, described bearing one end is provided with hole for injecting glue.The impeller body assembly of the structure, in rotation process,
Balance and stability can be improved.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the sectional view of the utility model；
Fig. 2 is the structural schematic diagram of bearing；
Fig. 3 is the dimensional structure diagram of the utility model.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing.As shown in Figs. 1-3：A kind of impeller body assembly, packet
Integrally formed bottom plate 1 and base sleeve 2 are included, bearing 3 is provided in the base sleeve, described bearing one end is provided with hole for injecting glue 4, specifically
, described bearing one end is symmetrical arranged about bearing centre there are two hole for injecting glue, and the hole for injecting glue runs through bearing wall, and bearing is by oxygen
Change zirconium or peek is made.Viscose glue is injected into hole for injecting glue, bearing is made to be bonded together with base sleeve, effectively reduces bearing and base
The probability to relatively rotate between set, to effectively increase the balance and stability of the rotation of impeller body assembly.
It being further improved as to above-mentioned technical proposal, the bearing outer wall, which is inlayed, is provided with multiple memorial alloy bodies 5,
The position that base sleeve inner wall corresponds to each memorial alloy body is both provided with groove 6.In assembling process, outside memorial alloy body and bearing
Wall combines to form smooth cylindrical type outer wall, convenient for bearing is smoothly packed into base sleeve, in impeller body assembly rotation process, and axis
The frictional heat between fixing axle is held, makes memorial alloy body is heated to deform upon, the formation of memorial alloy body is caught in convex in groove
It rises, further avoids bearing and rotated relative to base sleeve, when impeller body assembly stops operating, the cooling of memorial alloy body restores shape
Memory, such bearing are no different with existing bearing.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
