Abstract

The utility model discloses a motor slip ring cover, which comprises a fixing end and a cover body covered outside a brush carrier, wherein the fixing end and the cover body are integrally welded; the cover body is made of a thin steel plate. According to the motor slip ring cover, the original casting slip ring cover is canceled; the overall structure of the motor slip ring cover is simplified and adjusted under the condition that the service performance of the motor slip ring cover is guaranteed, the motor slip ring cover is made of the thin steel plate except for the fixing end, and the fixing end is designed on an end cover or a fan housing; and meanwhile, the brush carrier can be preferentially mounted and adjusted, and then the slip ring cover is mounted, so that the time for assembling the whole slip ring structure is shortened by 1/3 in an assembling process, the material cost is saved by 1/3, and a fastening structure of the motor slip ring cover is reinforced.

Description

A kind of motor sliding ring cover

Technical field

The utility model relates to a kind of slip ring motor, relates in particular to a kind of slip ring cover of slip ring motor.

Background technology

At present, slip ring motor slip ring cover structure is used foundry goods aggregate erection structure usually.There is following problem in such mounting structure in manufacturing, assembling link and actual motion:

1, needs prior mfg. moulding die in the manufacture process,, also directly had influence on the production cycle of motor except the manufacturing expense of mould;

2, the whole weight of foundry goods slip ring cover lays particular stress on, and is assemblied in the load-bearing that has increased stiff end on the motor, has also increased the whole quality of motor; The operating vibration of motor also increases to some extent;

3, the foundry goods slip ring cover for alleviating its weight, has reduced the volume of slip ring cover in actual use to a certain extent.Therefore, the intracavity space of slip ring cover reduces thereupon, has directly had influence on the assembly space of motor sliding ring, and inconvenience has also increased the man-hour of slip ring assembling when installing, and has directly influenced the production efficiency of motor.

The utility model content

The purpose of the utility model is to provide a kind of motor sliding ring cover, and it has the characteristics simple, that cost is low, in light weight and efficiency of assembling is high of making, the problem that exists with the slip ring cover that solves slip ring motor in the prior art.

For reaching this purpose, the utility model adopts following technical scheme:

A kind of motor sliding ring cover, it comprises the cover body that stiff end is outer with covering on brush holder, and said stiff end and cover body are welded as a whole, and wherein, said cover body is processed by sheet metal.

Especially, said steel-sheet thickness is 3 ㎜.

Especially, said cover body is by a sheet metal punch forming.

Especially, said cover body is welded by the polylith sheet metal.

Especially, said stiff end is fixed on the electric motor end cap through set bolt.

The beneficial effect of the utility model does; Compared with prior art said motor sliding ring cover has been cancelled original foundry goods slip ring cover, because overall structure has been done to simplify adjustment under the situation that guarantees serviceability, except that stiff end, all adopts sheet metal to process; And with stiff end design on end cap or fan housing; Satisfy installation, adjustment that the brush holder assembling can be preferential simultaneously, carry out the installation of slip ring cover again, make whole slip ring structure time spent in the assembly process process shorten 1/3rd; Practiced thrift 1/3rd on the material cost; The fastening structure of motor sliding ring cover has obtained reinforcement simultaneously.

Description of drawings

Fig. 1 is the structural representation of the motor sliding ring that provides of the utility model embodiment 1.

Embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment.

See also shown in Figure 1ly, Fig. 1 is the structural representation of the motor sliding ring that provides of the utility model embodiment 1.

In the present embodiment; A kind of motor sliding ring cover comprises stiff end 1 and cover body 2, and said stiff end 1 is welded as a whole with cover body 2, and said stiff end 1 is fixed on the electric motor end cap 4 through set bolt 3; Said cover body 2 covers on outside the brush holder 5; By thickness is that 3 ㎜ sheet metals are processed, and said stiff end 1 weight of bearing whole slip ring cover because of needs, and its steel plate thickness is greater than the thickness of cover body 2 steel plates.

Said cover body 2 can be one-body molded through punching press by a sheet metal, also can will be welded by the polylith sheet metal simultaneously.

Said stiff end 1 also can be fixed on the motor fan housing as required, only need satisfy installation, adjustment that brush holder 5 assemblings can be preferential, and the installation of carrying out slip ring cover again gets final product.

Above embodiment has just set forth the basic principle and the characteristic of the utility model; The utility model is not limited by above-mentioned example; Can change with the change of the installation site of the processing mode of cover body and stiff end; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various variations and change, and these variations and change all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.

Claims
