Abstract
The utility model discloses a motor rear cover assembly, including the motor rear end cap with install the insulation board in the motor rear end cap, on the insulation board installation carbon brush spare, its characterized in that: the brush box of carbon brush spare has the extension design, and the drum wall of motor rear end cap is seted up the breach and is exposed by brush box and insulation board part, and the insulation board is equipped with the direction that the direction sand grip is used for the carbon brush in the brush box with the surface of brush box contact, the brush box forms by sheet metal is folding, and a power plug of fin shape is rolled over to its tip. The utility model discloses greatly made things convenient for the installation of carbon brush spare to dismantle, carbon brush job stabilization improves carbon brush life.
Description
Technical field
This utility model relates to a kind of motor, is specifically related to a kind of motor rear cover assembly.
Background technology
Motor has bonnet, the rear case component of motor includes back end cover for motor and the insulation board being arranged in back end cover for motor, carbon brush part is installed on insulation board, generally, the barrel of back end cover for motor is the cylindrical shape closed, carbon brush part is only in the cylinder interior cavity installation settings of back end cover for motor, shortcoming is: the installing/dismounting of first inconvenient carbon brush part, secondly because be limited to the barrel sizes of back end cover for motor, the length of carbon brush is the most severely limited, and carbon brush in use can constantly wear and tear, so the wearing-in period of carbon brush is shorter, therefore service life is the shortest；It addition, carbon brush easily rocks in brush box, it is unfavorable for the working stability of carbon brush.Further, back end cover for motor generally uses casting aluminium material, and cost is high.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of installing/dismounting greatly facilitating carbon brush part, carbon brush working stability, improves the motor rear cover assembly in carbon brush service life.
To this end, this utility model uses following scheme to realize:
Motor rear cover assembly, including back end cover for motor and the insulation board being arranged in back end cover for motor, carbon brush part is installed on insulation board, it is characterized in that: the brush box of carbon brush part has extension design, the cylindrical wall of back end cover for motor is offered breach and is exposed by brush box and insulation board local, and the surface that insulation board contacts with brush box is provided with the guiding guiding raised line carbon brush in brush box.
Brush box is folded by sheet metal and is formed, and its end folds the attaching plug of fin shape.
Back end cover for motor uses plastic material.
After using technique scheme, this utility model realize Advantageous Effects be: 1. the cylindrical wall of back end cover for motor offer breach by brush box and insulation board local expose, so installing/dismounting of carbon brush part just can be carried out outside back end cover for motor, the most greatly facilitates the installing/dismounting of carbon brush part；2. exposing due to brush box, brush box can carry out extension design, and therefore carbon brush can also lengthen accordingly, and the wearing-in period of carbon brush is elongated, improves service life；3. the guiding raised line design on insulation board surface, serves the effect of guiding to the head of carbon brush, reduces carbon brush rocking in brush box, and therefore carbon brush work becomes more stable；4. brush box is folded by sheet metal and is formed, and its end folds the attaching plug of fin shape, so can be realized the electrical connection of carbon brush and external wire by inserting mode, facilitate the installing/dismounting of carbon brush part；5. back end cover for motor uses plastic material, can be substantially reduced cost.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, motor rear cover assembly of the present utility model, including back end cover for motor 1 and the insulation board 2 being arranged in back end cover for motor 1, back end cover for motor 1 uses plastic material, carbon brush part is installed on insulation board 2, the brush box 4 of carbon brush part has extension design, and the cylindrical wall of back end cover for motor 1 offers breach 3 allows brush box 4 and insulation board 2 local expose, and the surface that insulation board 2 contacts with brush box 4 is provided with the guiding guiding the raised line 6 carbon brush in brush box 4；Brush box 4 is folded by sheet metal and is formed, and its end folds the attaching plug 5 of fin shape.
