Abstract
The utility model discloses a commutator cooling device comprising an insulating gasket. A fan structure is arranged along the outer circumferential surface of the insulating gasket and comprises multiple fans and heat-dissipating holes. The multiple fans are uniformly distributed on the outer circumferential surface of the insulating gasket. The heat-dissipating holes are formed between adjacent fans. The outer sides of the multiple fans are integrally connected to form a loop. Based on the original insulating gasket, the fan structure is arranged on the outer circumferential surface of the insulating gasket and is reinforced. Air cooling is generated by the fans so as to decrease temperature of the surface of the commutator. Further, an effect of preventing a part of dust from corroding the commutator of a motor and a solenoid surface is achieved and the service life of the commutator is prolonged.
Description
Technical field
The utility model relates to a kind of commutator cooling device.
Background technology
Rotor rotates in stator, and in prior art, commutator is equipped with in rotor one end, the rotor other end is provided with fan, although the setting of fan can reduce the temperature of stator interior, the temperature of commutator end is still very high, part ash bits corrode engine commutator and line bag surface, have reduced useful life.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
For addressing the above problem, the utility model provides a kind of commutator cooling device, can reduce the temperature rise of commutator portion.
The technical solution adopted in the utility model is:
A kind of commutator cooling device, comprise insulating washer, this insulating washer has increased by a circle fan structure along its outer circumference surface, this fan structure comprises multiple fans and louvre, multiple fans are distributed on the outer circumference surface of insulating washer, between adjacent fans, form louvre, the outer side edges integrated connection of multiple fans forms a circle.
Described fan is tilting flabellum, the inclined angle alpha of each tilting flabellum, 3 °≤α≤10 °.
The beneficial effects of the utility model: utilize former insulating washer for basis, a circle fan structure strengthening have been increased in its outer ring, produce air-cooled by fan, reduce the temperature of commutator face, also play in addition the effect that stop portions ash bits corrode engine commutator and line bag surface, extended useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the rotor schematic diagram that the utility model commutator cooling device is housed.
Wherein: 1, insulating washer, 2, fan, 3, louvre, 4, circle, 5, rotor, 6, commutator, 7, brush, 8, brush carrier, 9, fan blade.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to protection range of the present utility model.
As shown in Figure 1, a kind of commutator cooling device of the present utility model, comprise insulating washer 1, this insulating washer 1 has increased by a circle fan structure along its outer circumference surface, this fan structure comprises multiple fans 2 and louvre 3, multiple fans 2 are distributed on the outer circumference surface of insulating washer 1, form louvre 3 between adjacent fans 2, and the outer side edges integrated connection of multiple fans 2 forms a circle 4.
Fan 2 is tilting flabellum, and the inclined angle alpha of each tilting flabellum is 5 °.
Shown in Fig. 2, rotor 5 one end are commutator 6, in commutator 6 sides, commutator cooling device are installed, and commutator 6 upper and lowers are brush 7, and brush 7 is placed in brush carrier 8, are original fan blade 9 away from commutator 6 sides.Original fan blade 9 can reduce the temperature in stator, but can not directly reduce the temperature of commutator 6 sides.
Increase separately the words of fan structure in commutator 6 sides, waste material, utilize now former insulating washer 1 for basis, a circle fan structure strengthening have been increased in its outer ring, this structure has not only retained the function of original increase creepage distance, produces air-cooledly by fan 2, has reduced the temperature on commutator 6 surfaces, also play in addition the effect that stop portions ash bits corrode engine commutator and line bag surface, extended useful life.
Claims (2)
