Abstract
The utility model belongs to the motor field, a there is brush motor end cover structure, a there is brush motor end cover structure, including metal end cap, brush box die cavity and brush box, the brush box die cavity set up to be in on the metal end cap inner wall, the brush box inserts mould plastics in the brush box die cavity. Beneficial effect: through the brush box of moulding plastics of inserts on metal end cap, realize the product structure and simplify that the just crowded assembly and disassembling be convenient for improves work efficiency, reduction in production cost, the part uses total type to reduce simultaneously, reduces material cost, and metal end cap's rigidity is better than plastic end cover, and the during operation vibration is little to motor noise is little, long service life.
Description
Technical field
The utility model belongs to machine field, particularly relates to a kind of end cover structure being applicable to treadmill permanent-magnet DC brush motor.
Background technology
Major part electric motor end cap is all adopt multiple part to assemble at present, is generally divided into three kinds, and one holds composition for metal end and tubulose brush, and tubulose brush is held by screw fastening on end cap, is then fixed on brush box by welding by connection line; Another kind be metal end and wiring board, brush holder, base plate junctor etc. composition, wiring board by screw fastening on end cap; One is also had to be integrated injection structure. Wherein adopting first two end cap composition proposal because of its structure comparison complexity, assembling is difficult, and part price is higher; Integrated injection molding structure scheme, structure is simple, easy to assembly, but because its material is plastics, part integral rigidity is not enough, vibration when motor runs, can be produced, plastic end cover easily produces resonance, vibration affects the contact of carbon brush and reverser, and loose contact produces spark, thus affects product noise and life-span, and plastic end cover is easily damaged when falling, and causes quality product hidden danger.
Practical novel content
The purpose of this utility model overcomes prior art to there is integrated injection molding end cover structure rigidity deficiency, affects the defect in product noise and life-span, it is provided that a kind of brush motor end cover structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of brush motor end cover structure, comprise metal end, brush cell type chamber and brush box, described brush cell type chamber is arranged on described metal end inwall, and described brush box insert injection moulding is in described brush cell type chamber.
As preferably, described brush cell type cavity wall being provided with the anti-skidding post of protrusion, described brush box sidewall forms after insert injection moulding the locating slot mated mutually with described anti-skidding post. Being designed by anti-skid structure, form the locating slot mated mutually with described anti-skidding post in injection moulding process on brush box, anti-skidding post is wrapped by injectable plastic material, thus increases the sticking power of brush box and metal end, reaches skidproof effect.
Further, described anti-skidding post is axial arranged along described metal end.
As preferably, described brush box material is thermosetting resin. This material is high temperature resistant, and material under high temperature distortion is little, is not easily out of shape, and this material price is relatively cheap.
Useful effect: by insert injection moulding brush box on metal end, it is achieved product structure simplifies, is convenient to just squeeze assembling and disassemble, it is to increase working efficiency, reduces production cost, and part uses total class to reduce simultaneously, reduces material cost; And the rigidity of metal end builds than plastic end, vibrate little during work, thus motor noise is little, it may also be useful to the life-span is long.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model brush motor end cover structure schematic perspective view;
Fig. 2 is brush motor end cover structure explosive view.
Wherein: 1, metal end, 11. brush cell type chambeies, 12. anti-skidding post, 2. brush boxes, 21. locating slots.
Embodiment
Embodiment 1
As illustrated in fig. 1 and 2, a kind of brush motor end cover structure, comprise metal end 1 and to brush box 2, brush cell type chamber 11 it is provided with in described metal end 1, the anti-skidding post 12 that at least one pair of protrudes it is provided with in described brush cell type chamber 11, described anti-skidding post 12 is arranged along the axis of described metal end 1, and described brush box 2 insert injection moulding is in the brush cell type chamber 11 of metal end 1.
Wherein said brush box 2 material is thermosetting resin. This material is high temperature resistant, and material under high temperature distortion is little, is not easily out of shape, and this material price is relatively cheap.
At metal end 1 embedded component injection moulding brush box 2 in the application, structure is simple, and vibrates little during machine operation, thus motor noise is little, it may also be useful to the life-span is long. Forming the locating slot 21 mated with described anti-skidding post 12 phase in injection moulding process on brush box 2, anti-skidding post 12 is wrapped by injectable plastic material, thus increases the sticking power of brush box 2 with metal end 1, reaches skidproof effect, connects more firm.
It is to be understood that specific embodiment described above is only for explaining the utility model, and it is not used in restriction the utility model. Apparent change or the variation extended out by spirit of the present utility model are still among protection domain of the present utility model.
