Abstract
The utility model discloses a ventilation structure of a slip ring cover of a winding motor. A blade is arranged on the inner side of an air inlet on the front side of a housing and is driven by a motor shaft; an outer air deflector is arranged on the upper part of the housing; a plurality of air passages are constructed on the lower part of the outer air deflector through a bent inner guide plate and a straight inner guide plate; outlets of the air passages are respectively located on the upper part of each group of slip rings and the upper part of the winding; and an air outlet is arranged at the bottom of the housing. Under the conditions that the manufacturing cost is not increased and the safety and reliability of the motor are ensured, cooling air is introduced to the upper part of the slip ring cover and blown toward the slip ring directly through the fluid design, and therefore, the cooling effect of the slip ring can be greatly improved, carbon dust accumulation caused by axial ventilation is reduced to the maximum extent, the reliability of a slip ring brush yoke system is effectively improved, the cost is saved for enterprises selecting the motor with a protection level of IP23, and the hidden trouble for use is eliminated.
Description
Technical field
The utility model relates to technical field of motors, especially the slip ring cover aeration structure of coiling electric motor.
Background technology
Coiling electric motor slip ring problem is the chronic disease of a headache of puzzlement electromechanics trade and industrial and mining enterprises, and its main cause is not ventilated not smooth from slip ring, and toner discharge is ineffective, local carbon distribution short circuit, blows out, and has directly influenced the operation of whole production streamline.Slip ring is broadly divided into two types according to its degree of protection: the first kind is that the environment of plant is more abominable; The many environment of dust such as powder, coal check and correction; This type of environment is selected the higher slip ring aeration structure of degree of protection usually for use, and the independently slip ring cooling air duct that has been hedged off from the outer world is with the slip ring fault of avoiding the environment foreign material to bring; This type of slip ring cools off often complex structure, and maintenance and manufacturing cost are higher; Second type is that the environment of plant is better, and dusts such as coal, powder are few, and this type of environment is selected the lower slip ring aeration structure of degree of protection usually for use, and the slip ring chamber and the external world directly carry out heat exchange, and this type of slip ring is simple in structure, and maintenance and manufacturing cost are lower.And during this type of design of electrical motor, tend to because motor producer according to the axial ventilation thinking, has some setbacks and cause carbon dust to be discharged, carbon dust stops up, and brings the slip ring fault thus.
It is the cooling effect that improves slip ring that producer is also arranged at present, adopts the way that adds cooling blower on the slip ring cover, through cooling blower to the slip ring air blast; Slip ring cover is made octahedron, and two cooling blowers are contained on octahedral two sides, and the wind that blower fan produces directly blows to slip ring can improve the slip ring cooling; This kind forces the structure of cooling, and not only cost is higher; In case and the power supply source of blower fan breaks down, and then must influence the cooling of slip ring, thereby influence the operation of whole motor.
The utility model content
The applicant is the deficiency that overcomes above-mentioned slip ring cooling system; Take into full account environment operating mode enterprise machine operation characteristic preferably, work out a kind of slip ring cover aeration structure of coiling electric motor rational in infrastructure, the little wind speed of windage is high; Good cooling results, and be difficult for the accumulation carbon dust.
The technical scheme that the utility model adopted is following:
A kind of slip ring cover aeration structure of coiling electric motor; Be provided with fan blade in air inlet inboard, the front side of case; Fan blade drives through motor shaft; Wind deflector outside case top is provided with, some wind paths are constructed through baffler in bending and straight interior baffler in the wind deflector bottom outside, and its wind path outlet lays respectively at respectively organizes slip ring and winding top; Be provided with air outlet in the case bottom.
It is further characterized in that: spray anti-arc magnetic painting layer at said case surface of internal cavity.
The beneficial effect of the utility model is following:
The utility model is through technological innovation, and technical process is simple, safety, and action effect is obvious; In the situation that does not increase manufacturing cost; And guarantee under the condition of motor safety property and reliability, through fluid design cooling air is caused that slip ring end shield top directly brushes to slip ring again, can improve the slip ring cooling effect greatly; Reduce the carbon dust accumulation that axial ventilation brings to greatest extent; Effectively improve slip ring brush holder system reliability, make environmental condition preferably factory and enterprise when selecting degree of protection to be the motor of IP23, provide cost savings, also got rid of use hidden danger simultaneously.
Description of drawings
Fig. 1 looks sketch map for the master of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 1; The utility model is provided with fan blade 2 in air inlet inboard, the front side of case 6; Fan blade 2 drives through motor shaft 8; Wind deflector 5 outside case 6 tops are provided with, some wind paths are constructed through baffler in bending 3 and straight interior baffler 4 in wind deflector 5 bottoms outside, and its wind path outlet lays respectively at respectively organizes slip ring 9 and winding top; And baffler 3 has less collection air port with the tip designs of straight interior baffler 4 in the bending.Be provided with air outlet in case 6 bottoms.Air inlet is equipped with air intake web plate 1, and air outlet is installed air-out web plate 7 and outlet housing.At the anti-arc magnetic of case 6 surface of internal cavity spraying one deck painting layer.
During real work, cooling air gets into case 6 from the air intake web plate of air inlet 1, is divided into two-way by baffler 3 and 4 in streamlined in the slip ring cover through fan blade 2, wind deflector 5 and case 6 sealings outside and blows to the slip ring surface from top to bottom, is discharged by air-out web plate 7 again.Fan blade 2 is contained in case 6 front portions, with motor shaft 8 with changeing, and interior baffler 3 becomes a less collection air port with 4 tip designs, the distinguished and admirable slip ring surface that directly blows to, thereby to guarantee providing enough blast to take away the carbon dust of carbon brush wearing and tearing generation.The fairing design can effectively reduce windage, improves wind speed.And at the anti-arc magnetic paint of case 6 surface of internal cavity spraying one deck, make surface of internal cavity very smooth, effectively prevented carbon dust adhering at inner chamber.Final toner can directly be discharged from the air-out web plate 7 of case 6 bottoms, stops up for preventing web plate, only needs periodic cleaning air-out web plate 7 to get final product; Outlet housing is a hemispherical dome formula structure, helps the smooth discharge of wind-guiding and carbon dust.
The utility model can replace band fully and force the wind path structure of blower fan to the slip ring air blast; A cover low-tension supply and the relevant control system of forcing the supporting increase of cooling blower because of increase have been eliminated; And the existence of cooling blower has increased extra unreliable factor, and the utility model provides power through the fan blade with motor coaxle, has the identical life-span with motor; Basically independent inefficacy can not take place, thereby improved the reliability of complete machine.
More than describing is the explanation to the utility model; Be not the qualification to utility model, the utility model institute restricted portion is referring to claim, under the situation of the utility model spirit; The utility model can be done any type of modification; For example fan is placed tail end, between bearing and slip ring, form similar cooling air duct structure.
