Abstract

The utility model relates to a motor pinion stand comprising a pinion stand body. An outer periphery of the pinion stand body is provided with an inwardly-bent annular-shaped edge, which is tightly assembled with an internal side of a motor lower housing. The height of the edge is in a range from 1mm to 5mm, and the height of the edge is 2mm. The motor pinion stand is advantageous in that the material costs can be reduced, the noises during the operation of the motor can be reduced, and at the same time, the quality of the product assembled with the motor lower housing can be improved.

Description

Motor gear seat

Technical field

The utility model relates to a kind of motor component, relates in particular to a kind of motor gear seat.

Background technology

At present, the mode that known motor gear seat is combined with electric machine casing is: in the outer rim of pinion stand, protrude two or three cattle horn shape supports, what pinion stand outer rim and motor lower casing adopted is loose fit, the coil of electric machine casing inside is withstood in pinion stand bottom, and cattle horn shape cantilever tip is withstood the upper cover of electric machine casing and fixed.There is following problem in this structure: the one, and the waste material that processing cattle horn shape support produces is more, has increased material cost; The 2nd, the loose fit form that pinion stand and motor lower casing adopt, during motor operation, the noise of generation is larger.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of motor gear seat is provided, and the noise while having reduced material cost and motor operation, has also improved the product quality with the assembling of motor lower casing simultaneously.

In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of motor gear seat, comprises pinion stand body, and the outer rim of described pinion stand body is provided with for the edge of inwardly digging with motor lower casing internal diameter close fit.

For the improvement of technique scheme, described edge be shaped as ring-type.

For the further improvement of technique scheme, the height at described edge is 1 ~ 5mm.

For the further improvement of technique scheme, the height at described edge is 2mm.

Implement the utility model embodiment, there is following beneficial effect:

(1) reduce the waste of material, thereby reduced production cost;

(2) owing to changing the loose fit form of motor gear seat and motor lower casing into close fit form, thereby reduced the noise in motor operation course;

(3) promoted the product quality of motor gear seat and the assembling of motor lower casing.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:

The structural representation of a kind of motor gear seat that Fig. 1 provides for the utility model embodiment;

The A-A face cutaway view of a kind of motor gear seat that Fig. 2 provides for the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.

Embodiment:

As depicted in figs. 1 and 2, motor gear seat described in the utility model, comprise pinion stand body 1, outer rim at described pinion stand body 1 is provided with the edge 2 of inwardly digging, described edge 2 is for the internal diameter close fit with motor lower casing, in assembling process, only need utilize tool that pinion stand body 1 is pressed into described motor lower house and can complete combining closely of the two, this assembling process is simple to operate, quick.

On described pinion stand body 1, process the simple to operate of edge 2, can not waste material, thereby greatly save production cost simultaneously.

Described edge 2 be shaped as annular, further improved the tightness coordinating and the product quality of described pinion stand body 1 and electric machine casing.Wherein the height at this edge 2 is 1 ~ 5mm, conventionally adopts 2mm the most general.The height at described edge 2 is by the size dimension of motor lower casing, to be adjusted completely, according to reality is required, determines.

The technical scheme above the utility model embodiment being provided is described in detail, applied specific case herein the principle of the utility model embodiment and execution mode are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.

Claims (4)

1. a motor gear seat, comprises pinion stand body (1), it is characterized in that:

The outer rim of described pinion stand body (1) is provided with for the edge of inwardly digging (2) with motor lower casing internal diameter close fit.

2. motor gear seat according to claim 1, is characterized in that:

Described edge (2) be shaped as ring-type.

3. motor gear seat according to claim 1, is characterized in that:
