Abstract
The utility model relates to an electric tool technical field especially relates to the cooling motor commutator fan in the electric hammer, including the motor, be equipped with the motor commutator on the motor, motor commutator below is equipped with little fan. Compared with the prior art, the utility model discloses a take the motor commutator of fan, the department increases a little fan at motor rotor commutator, and in the time of motor work, little fan also starts provides the amount of wind, produces high temperature to friction between commutator in the work and the carbon brush subassembly effectively and lowers the temperature, can also blow away the carbon dust that the friction of commutator and carbon brush subassembly produced, avoid appearing the carbon dust and pile up and burn out the phenomenon of motor to the extension motor life -span.
Description
Technical field
The utility model relates to electric tool technical field, particularly relates to the cooling motor commutator fan in electric hammer.
Background technology
The motor commutator place that Present Domestic is sold is not with small fan, brings friction aggravation between commutator and carbon brush and produce high temperature when Yin Mada runs up; If continuous firing, the high temperature produced can not get the life-span that effective cooling certainly will affect motor.
Therefore, be badly in need of providing a kind of cooling motor commutator fan, to solve the deficiencies in the prior art.
Utility model content
With Given this, the utility model provides a kind of cooling motor commutator fan for the deficiencies in the prior art, a small fan is increased at motor commutator place, while motor operations, small fan also starts provides air quantity, effectively produces high temperature to friction between the motor commutator in work and carbon brush component and lowers the temperature; Motor commutator and the fricative carbon dust of carbon brush component can also be blown away, avoid occurring that carbon dust is piled up and burns out the phenomenon of motor, thus extend motor life.
For achieving the above object, the utility model adopts following technical scheme:
Cooling motor commutator fan, comprises motor, and described motor is provided with motor commutator, is provided with small fan below described motor commutator.
More preferably, described small fan is press-fitted in described motor commutator place.
More preferably, the rotating shaft of described small fan and described motor is interference fit.
More preferably, described small fan comprises ring-type small fan body, and the one side of described ring-type small fan body is provided with some flabellums, and described flabellum is towards described motor commutator.
More preferably, described small fan is formed by plastic-injection.
More preferably, be provided with bearing below described small fan, the rotating shaft of described bearing and described motor is interference fit.
More preferably, described motor is located in described motor chassis, and the both sides of described motor commutator are provided with carbon brush component.
The utility model discloses cooling motor commutator fan, comprise motor, described motor is provided with motor commutator, is provided with small fan below described motor commutator.Compared with prior art, cooling motor commutator fan of the present utility model, increase a small fan at motor commutator place, while motor operations, small fan also starts provides air quantity, effectively produces high temperature to friction between the motor commutator in work and carbon brush and lowers the temperature; Motor commutator and the fricative carbon dust of carbon brush can also be blown away, avoid occurring that carbon dust is piled up and burns out the phenomenon of motor, thus extend motor life.
Accompanying drawing explanation
Fig. 1 is the exploded view of cooling motor commutator fan of the present utility model.
Fig. 2 is the overall diagram of cooling motor commutator fan of the present utility model.
Embodiment
Be further described the utility model below in conjunction with embodiment, this is preferred embodiment of the present utility model.
Embodiment 1
As shown in accompanying drawing 1-2, cooling motor commutator fan, comprises motor 1, and described motor 1 is provided with motor commutator 2, is provided with small fan 3 below described motor commutator 2.Increase a small fan 3 at motor commutator 2 place, while motor 1 works, small fan 3 also starts provides air quantity, effectively produces high temperature to friction between the motor commutator 2 in work and carbon brush component 6 and lowers the temperature; Motor commutator 2 and the fricative carbon dust of carbon brush component 6 can also be blown away, avoid occurring that carbon dust is piled up and burns out the phenomenon of motor 1, thus extend motor 1 life-span.
More preferably, described small fan 3 is press-fitted in described motor commutator 2 place.
More preferably, described small fan 3 is interference fit with the rotating shaft 11 of described motor 1.
