At present, the end cap of existing electric rotating machine and brush holder assemblies device on market, as shown in Figure 1, embed in the radial circumference of end cap by uniform for 2 brush tubes, 2 brushes are placed in 2 brush tubes respectively, the outer face of brush, by the pressure of spring, makes brush shorten along the direction CONTACT WITH FRICTION of commutator, and the lead-out wire of motor is from the sagittal plane outlet of end cap; But there is many deficiencies in this kind of structure:
One, along with after the wearing and tearing of brush shorten, the pressure of its spring to brush diminishes gradually, and the contact friction force of brush and commutator is also diminished gradually, causes motor spark to become large gradually, and noise becomes large, and motor performance is unstable;
Two, end cap embeds brush tubes diametrically, then the thickness of end cap must be greater than the external diameter of brush tubes, and therefore the amount of end cap non-ferrous metal used strengthens, and causes raw-material waste; Further, the through hole required precision of end cap being installed brush tubes is high, must adopt Vehicle Processing, add processing cost;
Three, lead-out wire is from the sagittal plane outlet of end cap, easily causes the external insulation skin damaged in collision of lead-out wire, causes motor electric leakage, open circuit, and the problem such as do not operate.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of electric rotating machine end cap and brush holder assemblies device are provided, to cause because wear of brush diminishes that motor spark is large, noise large, the problem of unstable properties to solve contact friction force between the brush of original end cap and brush holder assemblies device and commutator, and lead-out wire is by the sagittal plane outlet of end cap, easy damaged in collision causes motor electric leakage, open circuit, out-of-operation problem.
The object of the invention is to be achieved through the following technical solutions:
A kind of electric rotating machine end cap and brush holder assemblies device, comprise end cap and brush box, described end cap is provided with outlet guard ring, and end face is fixedly connected with mounting panel, described mounting panel is symmetrically arranged with a pair brush box, described brush box is by the transverse slat a of the envelope longitudinally arranged and envelope both sides, transverse slat b is formed, described envelope longitudinally has the through hole for placing brush, described brush slides and is arranged in the through hole of envelope, the transverse slat a of envelope side is installed with disc spring, and symmetry has two disc spring stroke grooves on envelope, the end of brush is pressed in one end of the disconnected transverse slat a of described disc spring, the inner face of described brush contacts with commutator, its outer face is connected with the transverse slat b of envelope opposite side by wire, brush is also connected with lead-out wire, described lead-out wire is through the outlet guard ring in end cap, by the axial end outlet of end cap.
Further, described end cap is provided with boss, described boss matches with the draw-in groove on mounting panel, and mounting panel is fixedly connected with end cap by screw.
Further, described mounting panel and brush box are riveted.
Preferably, described mounting panel is epoxy plate, while keeping flexibility, provide intensity.
Further, the end face of described end cap has a breach, the bore of the upper/lower terminal of described breach is less than the bore in the middle of breach, and described outlet guard ring matches with breach, is arranged in the breach of end cap.
Preferably, described outlet guard ring is can open and close type, is made up of nylon or plastics, assembling front opening, and after lead-out wire being loaded outlet guard ring, fastening hasp, puts into end cap after closed.
Preferably, the end face of the disconnected mounting panel of described end cap is provided with non-through shrinkage pool, to alleviate the weight of end cap self, saves material.
Beneficial effect of the present invention is, described electric rotating machine end cap and brush holder assemblies device make the contact friction force of brush and commutator remain unchanged, and have the characteristic of good anti-brush chattering, stabling current can be provided not easily to produce electric spark again to rotor winding, electric noise, reduce wear, thus improve operational reliability and the useful life of motor; And ending cover thickness is light, thin, the non-through shrinkage pool of the outer surface setting of end cap, plays the effect alleviating end cap deadweight, the consumption of the non-ferrous metal saved greatly, cost-saving; In addition, use outlet guard ring, make lead-out wire from the axial end outlet of end cap, well protect wire, structure is simple, safe and reliable.
