Two, end cap embeds brush tubes diametrically, and then the thickness of end cap must be greater than the external diameter of brush tubes, so the amount of the used non-ferrous metal of end cap strengthens, and causes raw-material waste; And the through hole required precision that brush tubes is installed on the end cap is high, must adopt Vehicle Processing, has increased processing cost;
Three, lead-out wire causes the external insulation skin damaged in collision of lead-out wire easily from the sagittal plane outlet of end cap, causes motor electric leakage, opens circuit, and problem such as do not turn round.
The utility model content
The purpose of the utility model is to the problems referred to above; Provide a kind of electric rotating machine with end cap and brush holder assemblies device; Because of diminishing, wear of brush causes with contact friction force between the brush that solves original end cap and brush holder assemblies device and the commutator that motor spark is big, noise big, the problem of unstable properties; And lead-out wire is by the sagittal plane outlet of end cap, and damaged in collision causes that motor leaks electricity, opens circuit, out-of-operation problem easily.
The purpose of the utility model is to realize through following technical scheme:
A kind of electric rotating machine comprises end cap and brush box with end cap and brush holder assemblies device, and said end cap is provided with the outlet guard ring; And be fixedly connected with mounting panel on the end face, be symmetrically arranged with the pair of electrical brush box on the said mounting panel, said brush box is made up of the envelope of vertical setting and transverse slat a, the transverse slat b of envelope both sides; Said envelope vertically has the through hole that is used to place brush; Said brush slides and is arranged in the through hole of envelope, be installed with disc spring on the transverse slat a of envelope one side, and symmetry has two disc spring stroke grooves on the envelope; The end of the disconnected transverse slat a of said disc spring presses the end of brush; The inner face of said brush contacts with commutator, and its outer face is connected with the transverse slat b of envelope opposite side through lead, also is connected with lead-out wire on the brush; Said lead-out wire passes the outlet guard ring in the end cap, by the axial end outlet of end cap.
Further, said end cap is provided with boss, and said boss matches with draw-in groove on the mounting panel, and mounting panel is fixedly connected with end cap through screw.
Further, said mounting panel and brush box riveted joint.
Preferably, said mounting panel is an epoxy plate, and intensity is provided when keeping flexible.
Further, have a breach on the end face of said end cap, the bore of the upper/lower terminal of said breach is less than the bore in the middle of the breach, and said outlet guard ring matches with breach, is arranged in the breach of end cap.
Preferably, but said outlet guard ring is an open and close type, is processed by nylon or plastics, and the assembling front opening is packed lead-out wire behind the outlet guard ring into, and the fastening hasp is put into end cap after the closure.
Preferably, the end face of the disconnected mounting panel of said end cap is provided with non-through shrinkage pool, to alleviate the weight of end cap self, saves material.
The beneficial effect of the utility model does; Said electric rotating machine makes the contact friction force of brush and commutator remain unchanged with end cap and brush holder assemblies device; And the characteristic that good anti-brush chattering is arranged can provide stabling current to be difficult for producing electric spark, electric noise again to the rotor winding; Reduce wear, thus the operational reliability and the useful life of improving motor; And ending cover thickness is light, thin, and the non-through shrinkage pool that the outer surface of end cap is provided with plays the effect that alleviates the end cap deadweight, and the consumption of the non-ferrous metal of practicing thrift is greatly practiced thrift cost; In addition, use the outlet guard ring, make lead-out wire, well protected lead from the axial end outlet of end cap, simple in structure, safe and reliable.
