Description
Technical field
The utility model is a kind of carbon brush structure of carbon brush motor, and particularly a kind of interchangeable carbon brush structure of carbon brush motor belongs to the carbon brush component technology field of motor.
Background technology
The carbon brush motor mainly commutates to direct current with carbon brush and commutator, thereby motor can be turned round continuously, because of carbon brush and commutator have certain friction, and the motor running certain hour, carbon brush can at first wear and tear, and causes motor life to stop.Conventional carbon brush for motor structure has following several mode usually:
First kind of mode: carbon brush is connected with terminal by brush holder, and is fixed on (shown in Fig. 1-1,1-2) on the support.This mode is fit to low current, low-power motor.Its advantage is simple in structure, and cost is lower.Shortcoming is that to bear electric current little, and overload capacity is little, and when big electric current, brush holder loses elastic force or fracture owing to current density is easy to generate the annealing phenomenon greatly; Life-span is short, and carbon brush is not interchangeable, has ground the back motor and has promptly scrapped.
The second way: carbon brush by brush box with brush box bottom board simultaneously riveted and fixed on support,, and produce elastic force (shown in Fig. 2-1,2-2,2-3) by torsion spring.This mode is fit to high electric current, large capacity motor.Its advantage is a Stability Analysis of Structures, the motor excellent in durability.Shortcoming is that carbon brush is not interchangeable, has ground the back motor and has promptly scrapped the cost height.
The utility model content
The purpose of this utility model is in the above-mentioned prior art, it is little that the carbon brush structure of carbon brush motor bears electric current, overload capacity is little or carbon brush is not interchangeable, having ground the back motor promptly scraps, defect of high cost, a kind of interchangeable carbon brush structure of carbon brush motor is provided, can have reached the purpose that the structure assembling is simple and reliable, overload capacity strong, carbon brush can provide for simple replacement of.
The technical scheme taked of the utility model is to achieve these goals: a kind of interchangeable carbon brush structure of carbon brush motor, comprise brush box, carbon brush, snail shape spring and support, also comprise brush box bottom board, described brush box bottom board and brush box, carbon brush, the fixing assembling of snail shape spring carbon brush component in aggregates; Described brush box bottom board comprises fit structure A, C, E, and fit structure A is a kind of square orifice structure, and fit structure C is a kind of chamfering structure, and fit structure E is a kind of convex structure; Described support comprises fit structure B, D, F, fit structure B is a kind of back-off structure, fit structure D is a kind of draw-in groove structure, fit structure F is a kind of platform structure, carbon brush component cooperates with fit structure F's with fit structure D, fit structure E with fit structure B, fit structure C by fit structure A, removably is connected one with support.
Described brush box bottom board bottom is arranged with 2 rectangle hole slotted eyes of symmetry mutually in parallel, and brush box one end is inserted in the rectangle hole slotted eye, is connected with the riveted joint of rectangle hole slotted eye; Described carbon brush is inserted in the brush box; Described snail shape spring is connected with the brush box bottom board close-fitting by the buckle structure on the brush box bottom board.
The front end of the fit structure B of described support is a back-off portion, and back-off portion buckles into the fit structure A of brush box bottom board, and in promptly a kind of square orifice structure, the inner edge of withholding limit and a kind of square orifice structure of back-off portion front end fits tightly.
The fit structure A of described brush box bottom board, promptly a kind of square orifice structure portion that stretches out is a structure of right angle tyoe on the brush box bottom board.
Compared with prior art, the beneficial effects of the utility model are:
(1) do brush box, brush box bottom board, carbon brush and snail shape spring as a whole, but ease of assembly and dismounting, realized the commutativity of carbon brush, when motor running to end-of-life, promptly carbon brush grind, then a need be removed terminal button point, the brush box bottom board structural entity is taken out, can continue to use new brush box bottom board structural group being installed on the support motor, prolong the useful life of motor greatly, reach energy-conservation effect;
(2) the back-off mode is easy to assembly simple, when needing to change after carbon brush grind, needs only brush box bottom board according to the F shown in Figure 83 to exerting all one's strength slightly, make the right-angle structure on the brush box bottom board produce certain elastic deformation, the close-fitting arrangement uncouples can be need not any equipment, reduce production cost;
(3) the utility model has adopted a kind of back-off to connect design, the assurance brush box bottom board can easily be tipped support in, after fastening, the design that relies on a kind of socket connection to be connected with a kind of close-fitting, brush box bottom board and support can be linked closely and can not get loose, still guarantee the fastness of motor bracket assembly, so can guarantee the normal use of motor; And the high electric current of motor, powerful characteristics have been inherited.
