Compared with prior art, the utility model has the following advantages:
(1) material saving, economize part, lightweight:
Traditional metal end and brush basin are integrated, therefore eliminate brush cone material;
Because this integrated (afterwards) end cap have employed the good plastic material of rigidity, its central authorities have a cylindrical hole can be fixed together with the axle of motor (static), axle is connected with bearing inner race, and drives armature running by bearing outer ring, thus eliminates front end housing;
Three Kong Zhu of this electric device periphery are fixed together by screw (preferably high and low tooth) and mounting bracket, can save three gussets and three nuts, three screws of conventional motors;
The material supporting the spill guide rail of brush is the own material of integrated end cap, thus eliminates the brush carrier material (copper) of traditional structure;
The direct ground connection of negative pole, save an electric capacity, and filter effect is suitable than traditional π shape filter circuit;
The direct butt-joint of lead-out wire of brush and inductance, electric capacity, ground strip, power supply connects together, and eliminates brace.
(2) manufacturing procedure is few, dimensional accuracy is higher, save space and axial distance:
Brush basin, brush carrier, brace, inductance folder, front end housing are not installed, thus there is the advantage that manufacturing procedure is few, cumulative limit is little, dimensional accuracy is easier to guarantee, also save space and axial distance simultaneously, make the motor that is assembled into less than general motor volume, more flat.
(3) reliability is high, the life-span is long:
Electric device of the present utility model, eliminates brush basin, front end housing, brush carrier etc., is conducive to the heat radiation of brush and motor internal; Brush is showed naked, between the bottom surface of brush and end cap, leave enough gaps, the possibility by carbon dust blocked of brush in brush carrier can be avoided; Brush front end contacts with commutator, and its rear end is subject to the elastic force coming from stage clip, and the plane that brush two groove at side surfaces are embedded in spill guide rail can make relative sliding, brush and lead rail axis good to contacting, the reliable and stable work of brush can be guaranteed; Brush is had ready conditions suitably increases length to improve life-span and increasing power further; Thus product reliability is high, long service life.
(4) the stage clip diameter of traditional structure is equally large, and for preventing stage clip from deviating from brush carrier, plastics brush carrier need increase thrust plate in this way, not only adds operation, and have impact on the use length of brush; Copper brush carrier in this way, increase after brush carrier installs stage clip and close the door operations such as (material) bending, when this process operations not at that time, likely make brush carrier be out of shape, thus also need to increase and detect operation.
And stage clip of the present utility model, be made up of large footpath standing part and path working portion two parts, participate in the stage clip of working portion be positioned at guide rail under deep-slotted chip breaker, standing part is arranged in the open slot of guide rail, prevent stage clip from departing from deep-slotted chip breaker, because stage clip contact is reliable, thus it stablely forces in brush.Not only with low cost, simple for structure, and operation is few, reliability is high.
(5) left and right of gland is equipped with hole ear, adopts partially softer plastics, is conducive to strutting lug, thus covers on the boss of integrated end cap easily, and being provided with a more than half circular hole in the middle of it, is for the ease of accurately locating with more than half cylinder of end cap.
