Technical field
The utility model relates to a kind of motor accessory, and in particular, it relates to a kind of brush motor rotor.
Background technology
There is in the market a kind of brush motor, it includes rotating shaft, winding, commutator and impeller, the impeller of motor adopts single-sided impeller, this single-sided impeller exists a lot of inconvenience: although the first monolithic blade wheel structure is simple, but because blade is thin, easily lose in the process of electric machine rotation; The second, blade one side, wind-force is little, can not effectively discharge the heat of motor internal, affects the normal operation of motor.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of brush motor rotor, the impeller of this brush motor rotor can be stable be arranged in rotating shaft, and impeller can produce the wind-force more strengthening, the heat producing while effectively discharging rotating shaft work, this blade strength is high, is difficult for losing, make rotor in a good operational environment, guarantee effective work of motor.
For achieving the above object, the utility model provides following technical scheme: a kind of brush motor rotor, comprise impeller, rotating shaft, commutator, commutator is arranged on rotating shaft one end, impeller is arranged on the other end of the relative commutator of rotating shaft, impeller comprises installation portion in the form of annular discs and is arranged on the installation portion blade in symmetrical both ends of the surface each other, the center of installation portion is provided with shaft hole, blade is circumferential setting and is in staggered distribution successively along shaft hole, shaft hole is wholely set the keyway towards the shaft hole center of circle, and rotating shaft is provided with the key coordinating with keyway.
By adopting technique scheme, the key that the keyway on shaft hole is provided with rotating shaft coordinates, and makes like this impeller to be stably arranged in rotating shaft, in the time that rotating shaft is worked, makes impeller be difficult for running and flies, and guarantees the normal work of impeller; Blade is fixed on installation portion, and installation portion has been shared the impulsive force of blade, has improved the intensity of blade, makes the blade can be because of stressed large and damaged in rotation process; Blade is circumferential setting and is in staggered distribution successively along shaft hole, make to produce and form passage between blade and blade, thereby the air-flow that blade produces refluxes effectively between blade, and energy efficiently radiates heat; The opposite ends of impeller installation portion is provided with blade, in the time that rotating shaft is rotated, and the blade working of impeller installation portion both sides, can produce the wind-force more strengthening, the heat producing while effectively discharging rotating shaft work, makes rotor in a good operational environment, guarantees effective work of motor.
The utility model is further set to: the installation portion of described impeller is provided with air vent hole, and described air vent hole is distributed between each blade.
By adopting technique scheme, the installation portion of impeller is provided with air vent hole, and in the time of the blade working at installation portion two ends, the air-flow that blade produces can carry out by air vent hole the mutual conversion of air-flow, can avoid the obstruction of impeller generation heat.
The utility model is further set to: the cross section of described blade is fan annular.
By adopting technique scheme, blade profile is fan annular, and the blade of fan ring section can produce a thrust to air at rotation process, and by the lasting rotation of impeller blade, air is constantly promoted by blade, forms wind; The blade of fan ring section makes in the time that impeller is worked, and blade receives the stressed of wind can be even, thereby the life-span of blade is lengthened.
The utility model is further set to: described rotating shaft is threaded with commutator.
By adopting technique scheme, external screw thread in rotating shaft makes rotating shaft closely be connected with commutator after being threaded with the internal thread of commutator, be threaded and manufacture and use simple, connect reliable, easy to use, versatility is good, detachable and reuse, commutator is threaded with rotating shaft, in the time that commutator breaks down, can directly spin down individual inspiration and change timely from rotating shaft.
