Abstract
The utility model discloses a motor rear cover, comprising a cover-shaped body surrounded by a bottom surface and a vertical wall, wherein two brushing frame are relatively arranged in the cavity of the body; the brushing frame is a cuboid element, and a horizontal through hole is arranged at the center of the brushing frame; the rear end face of the cuboid element is connected with the inner side of the body vertical wall; a plurality of inclined reinforced ribs are arranged at the interval of the body vertical wall and the bottom inner side; the cuboid element, the reinforced ribs and the body is the element with one-shot molding of BMC material. The motor rear cover has the advantages of light weight, manpower saving, steady structure, long service life and mass production.
Description
Technical field
The utility model relates to a kind of back end cover for motor, relates to more specifically a kind ofly brushing frame and body is the back end cover for motor of integrated member.
Background technology
Back end cover for motor of the prior art, it generally is and covers shape, mostly by making by metal materials such as aluminium, be provided with some brush frames in this end cap inside, the brush frame is after split is made, to be fixed on the end cap by connectors such as screws, and its both sides generally also are provided with two insulation brush holder assist location, this brush holder also is after split is made, to be fixed on the end cap by connector.In actual manufacture process, at first need to cast out the end cap blank, and then through after the manufacturing procedures such as cutting, polishing, boring, the brush frame that in advance make again and brush holder etc., manually be installed on the end cap through streamline, the manual calibration precision is finished finished product at last then.Therefore, the end cap of this structure, exist that parts are many, processed complex, assembling is loaded down with trivial details, recruitment is many, error is big, cost is high, and installation personnel is had higher shortcomings such as specification requirement, is metal because of the finished product material in addition, its weight is heavier, and overall process is by manual operation, and brush frame and brush holder location exist gap and error, influences the motor running quality during use easily, be easy to generate vibrations and noise, and can not adapt to the standardization batch production requirement.
The utility model content
In order to solve the existing existing above-mentioned deficiency of back end cover for motor, the purpose of this utility model is that it is an integral body that a kind of body, brush frame are provided, with the plastic injection-moulded back end cover for motor that forms.
The utility model for achieving the above object, the technical scheme that is adopted is:
A kind of back end cover for motor, it comprises a lid shape body that is surrounded by bottom surface and wall, is relatively set with two brush frames in this body cavity, described brush frame is the cuboid member that the middle part is provided with a horizontal through hole; The rear end face of this cuboid member is connected with described body wall inboard, and its lower surface is connected with the inboard of described body bottom surface; And this cuboid member and body are one-time formed one plastic cement member;
The through hole at described brush frame middle part penetrated described body wall simultaneously;
The upper surface of described body is a plane; Its middle part, bottom surface is provided with some through holes; Its wall is provided with some grooves, and wherein a groove is connected with described brush frame through hole;
Described body wall and inboard, bottom surface are interval with a plurality of oblique deep floors;
Described body, brush frame and deep floor are the one-time formed members of a BMC material.
Advantage of the present utility model is: because the utility model manufactures an integrated member with body, the several parts of brush frame, saved artificial assembling link, thereby human resources have been saved, and use the injection mo(u)lding of BMC material, the productivity ratio height, can produce in batches, BMC is a kind of novel moulding compound, has good electric property, mechanical performance, thermal endurance, chemical resistance adapts to various moulding processs again, easily processing and manufacturing, can satisfy arc-extinguish chamber material performance demands aspect pitch-durable performance and mechanical strength, be highly suitable in the arc-extinguish chamber and use.The BMC moulding compound is applied to electric motor end cap, alleviated product weight, strengthened the stability and the useful life of motor.
