CN203243160U - A motor end cover containing a shrinkage cavity - Google Patents

Abstract

The utility model discloses a motor end cover containing a shrinkage cavity. The motor end cover comprises a motor end cover body. A brush carrier plate assembly is disposed on the bottom of the motor end cover body. A bearing hole is disposed on the center of the brush carrier plate assembly and is a shrinkage cavity matched with a spherical oil-containing bearing. The motor end cover and the oil-containing bearing are pressed at one time through a shrinkage structure. Therefore, overcoming all defects of dispersedly-assembled independent components of an original motor end cover and an original oil-containing bearing, the motor end cover saves a lot of components, greatly decreases the cost of components and production assembly. In addition, the motor end cover completely achieves product facilitation and performance flexibility of the oil-containing bearing, and substantially increases the precision and the integral quality of the product.

Description

A kind of electric motor end cap with the harmomegathus hole

Technical field

The utility model relates to technical field of motors, especially a kind of electric motor end cap with the harmomegathus hole.

Background technology

Original motor end cap, spherical oiliness bearing (armature spindle matches), malthoid circle, spring bearer plate all are each independent parts, by secondary, three times, grab the seal frock and finish and press-fit oiliness bearing, its shortcoming is the process by each multiple tracks technique, the tooling device of multiple tracks technique and operation employee's operation assembling have been increased, caused the cost of tooling device investment to increase and multiple tracks technique in make mistakes, go out the raising of time relative risk and the raising of operating cost, the consistency of quality also is difficult to ensure simultaneously, therefore this kind infrastructure cost is large, of poor quality.

The utility model content

The technical problems to be solved in the utility model is: in order to solve the assembly problem between the existing electric motor end cap and spherical oiliness bearing in the above-mentioned background technology, provide a kind of electric motor end cap with the harmomegathus hole.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric motor end cap with the harmomegathus hole, comprise the electric motor end cap body, the body lower end is provided with brush rack plate, the central authorities of described brush rack plate are provided with a dead eye, and described dead eye is the harmomegathus hole that matches with spherical oiliness bearing.

The beneficial effects of the utility model are, the electric motor end cap that the utility model relates to and oiliness bearing once are pressed into by the expanding-contracting type structure, whole shortcomings that original motor end cap, each independent parts dispersion of oiliness bearing assemble have been overcome, thereby many parts have been reduced, and the earth has reduced parts cost and production and assembly cost, carried out the product summary fully, oiliness bearing performance flexibility has improved the precision of product and the advantages such as significant lifting of product total quality.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is harmomegathus pore structure schematic diagram in the utility model.

1. bodies among the figure, 2. brush rack plate assembly, 3. harmomegathus hole.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

The embodiment of a kind of electric motor end cap with the harmomegathus hole of the utility model as shown in Figure 1, comprise the electric motor end cap body, the body lower end is provided with the brush rack plate assembly, the central authorities of described brush rack plate assembly are provided with a dead eye, described dead eye is the harmomegathus hole that matches with spherical oiliness bearing, the electric motor end cap that the utility model relates to and oiliness bearing once are pressed into by the expanding-contracting type structure, overcome the original motor end cap, whole shortcomings that each independent parts dispersion of oiliness bearing assembles, thereby many parts have been reduced, and the earth has reduced parts cost and production and assembly cost, carried out the product summary fully, oiliness bearing performance flexibility has improved the precision of product and the advantages such as significant lifting of product total quality.

Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.

Claims (1)
