Abstract
The utility model discloses a carbon brush assembly structure which comprises an end cover and carbon brushes. A shaft hole is reserved in the center of the end cover. Carbon brush holding grooves are symmetrically reserved at two ends of the shaft hole. The carbon brush holding grooves are integrally formed with the end cover. Openings of the carbon brush holding grooves face the shaft hole directly. Each carbon brush holding groove comprises a first end and a second end away from the shaft hole. A carbon brush spring and a carbon brush are sequentially and movably disposed in each carbon brush holding groove from the second end to the first end. Each carbon brush is contacted with a commutator of a rotor through pressing of each carbon brush spring. Due to the fact that the carbon brush holding grooves are reserved inside the end cover, the carbon brushes are directly mounted in the carbon brush holding grooves, and the carbon brushes are tightly pressed to contact with the commutators, operation safety of a motor is enhanced, the carbon brush assembly structure is simple in structure and convenient to mount, part number is reduced, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of assembly structure, relates in particular to a kind of carbon brush assembly structure.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, and it is widely used in many electric equipments as a kind of sliding contact part.The material of carbon brush mainly contains electrographite, soaks fat graphite, metallic graphite carbon.In brush motor, the traditional mounting means of carbon brush is mounted in the brush box, contacts with commutator through the spring compression carbon brush, and the conducting electric current makes machine operation.Carbon brush assembly structure as shown in Figure 1, carbon brush 13 are installed in brush box 12 in the brush carrier 14 after being mounted in the brush box 12 again, and brush carrier 14 is normally processed with insulating material, isolate with the end cap 11 of metal, form insulation; After another kind of carbon brush assembly structure as shown in Figure 2, carbon brush 23 are mounted in the brush box 22, be installed on the brush holder 24 that epoxy plate or other insulating material process, form insulation with end cap 21.The assembly structure of above-mentioned two kinds of carbon brush, not only poor reliability, and complex structure is installed loaded down with trivial detailsly, has strengthened production cost virtually.
The utility model content
The purpose of the utility model is a kind of carbon brush assembly structure to be provided to the problems referred to above, solving traditional carbon brush assembly structure poor reliability, complex structure, install loaded down with trivial details, the characteristics that production cost is high.
The purpose of the utility model is to realize through following technical scheme:
A kind of carbon brush assembly structure comprises end cap and carbon brush, and said end cap center has axis hole; The two ends that its inside is positioned at axis hole are symmetrically arranged with the carbon brush holding tank; Said carbon brush holding tank and end cap are formed in one, and its opening is over against axis hole, and the carbon brush holding tank comprises first end and away from the second end of axis hole; Its interior slip successively by the second end to first end is provided with brush holder spring and carbon brush, and said carbon brush contacts with epitrochanterian commutator through the brush holder spring overhead.
Further, said end cap is processed by insulating material.
Preferably, said insulating material is plastics.
Further, be provided with installing hole in the said end cap.
Further, be positioned at carbon brush holding tank the second end side on the said end cap and have out wire casing.
The beneficial effect of the utility model does; Said carbon brush assembly structure directly is installed on carbon brush in the inner carbon brush holding tank of end cap at end cap set inside carbon brush holding tank, compresses carbon brush through brush holder spring and contacts with commutator; Not only strengthened the fail safe of motor operation; And simple in structure, easy for installation, reduce number of parts, thereby reduced production cost.
