Abstract
The invention discloses a kind of commutator cooling devices, including insulating washer, the insulating washer increases a circle fan structure along its outer circumference surface, the fan structure includes multiple fans and heat emission hole, multiple fans are distributed on the outer circumference surface of insulating washer, and heat emission hole is formed between adjacent fans, and the outer side edges of multiple fans are connected to form a circle, the top surface of the blade of fan is cambered surface, bottom surface is wavy surface, passes through fillet surface transition between the top and bottom of blade.The top surface of the blade of fan is set as cambered surface by the present invention, bottom surface is set as wavy surface, there is shrinkage phenomenon in this way, cambered surface can sponge the deformation of a part, the wavy surface of bottom surface again can be promptly so that fan be resetted simultaneously, generate the effect similar to spring, so that the blade of fan is promptly resetted when generating deformation, so as to effectively improve barrier properties of the fan for ash bits.
Description
Technical field
The present invention relates to commutator fields, and in particular to a kind of commutator cooling device.
Background technology
Rotor rotates in stator, and in the prior art, rotor one end is equipped with commutator, and the rotor other end is equipped with fan,
Although the setting of fan can reduce the temperature of stator interior, the temperature of commutator end is still very high, and part ash bits corrode electricity
Machine commutator and line packet surface reduce service life, therefore a circle wind can be added on its outer ring on some commutators now
Fan structure cools down, and stop grey bits.But due to the variation of temperature thereon so that the blade of fan often can be because of shrinkage
Reason cause gap occur between blade, so as to reduce for ash bits barrier properties.
Invention content
Blade can be effectively prevent the commutator in gap occur in order to solve the above technical problem, the present invention provides a kind of
Cooling device.
In order to achieve the above object, technical scheme is as follows：
A kind of commutator cooling device, including insulating washer, which increases a circle fan along its outer circumference surface
Structure, the fan structure include multiple fans and heat emission hole, and multiple fans are distributed on the outer circumference surface of insulating washer, adjacent wind
Heat emission hole is formed between fan, the outer side edges of multiple fans are connected to form a circle, and the top surface of the blade of fan is cambered surface, bottom
Face is wavy surface, passes through fillet surface transition between the top and bottom of blade.
Commutator cooling device provided by the present invention, is set as arc by the top surface of the blade of fan in the prior art
Face, bottom surface are set as wavy surface, and cause between the top and bottom of fan through fillet surface transition, show in this way there is shrinkage
As cambered surface can sponge the deformation of a part, while the wavy surface of bottom surface can promptly so that fan is resetted again, produce
The raw effect similar to spring, fillet surface can cause the effect of top and bottom to combine, can thus make again
The blade for obtaining fan is promptly resetted when generating deformation, so as to effectively improve barrier properties of the fan for ash bits.
Based on the above technical solution, the present invention can also improve as follows：
As a preferred option, above-mentioned two fillet surfaces positioned at fan both sides are arranged in parallel.
Using the above preferred scheme, the length of entire blade can be expanded so that for deformation reset effect more preferably.
As a preferred option, it is provided with square through-pipe between the two neighboring wave unit of above-mentioned bottom surface.
Using the above preferred scheme, the limiting operation to bottom surface deformation can be formed, ensures the stability of structure.
Description of the drawings

Fig. 2 is the structure diagram of blade involved in a kind of commutator cooling device of the invention.
Wherein：1. 23. bottom surface of insulating washer 2. fan, 21. blade, 22. top surface, 231. wave unit, 232. side is led to
24. fillet surface of pipe, 3. heat emission hole 4. encloses.
Specific embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figs. 1-2, in a kind of some of embodiments of commutator cooling device of the present invention, including insulation
Washer 1, the insulating washer 1 increase a circle fan structure along its outer circumference surface, which includes multiple fans 2 and heat dissipation
Hole 3, multiple fans 2 are distributed on the outer circumference surface of insulating washer 1, and heat emission hole 3 is formed between adjacent fans 2, multiple fans 2
Outer side edges are connected to form a circle 4, and the top surface 22 of the blade 21 of fan 2 is cambered surface, bottom surface 23 is wavy surface, blade 21
Pass through 24 transition of fillet surface between top surface 22 and bottom surface 23.The commutator cooling device that the present embodiment is provided, in the prior art
The top surface of the middle blade by fan is set as cambered surface, bottom surface is set as wavy surface, and to lead between the top and bottom of fan
Fillet surface transition is crossed, shrinkage phenomenon is occurring in this way, cambered surface can sponge the deformation of a part, while the wavy surface of bottom surface
Again can be promptly so that fan be resetted, generation is similar to the effect of spring, and fillet surface can cause top and bottom again
Effect combine, the blade of fan can thus be caused promptly to be resetted when generating deformation, so as to effectively
Improve barrier properties of the fan for ash bits.
In order to further optimize the implementation result of the present invention, as shown in Figs. 1-2, cooled down in a kind of commutator of the present invention
In other embodiments of device, on the basis of the above, above-mentioned two fillet surfaces 24 positioned at 2 both sides of fan are flat
Row setting.Using the scheme of the embodiment, the length of entire blade can be expanded so that for deformation reset effect more
It is good.
In order to further optimize the implementation result of the present invention, as shown in Figs. 1-2, cooled down in a kind of commutator of the present invention
In other embodiments of device, on the basis of the above, the two neighboring wave unit 231 of above-mentioned bottom surface 23 it
Between be provided with square through-pipe 232.Using the scheme of the embodiment, the limiting operation to bottom surface deformation can be formed, ensures structure
Stability.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
