Abstract
The utility model relates to an asynchronous motor, in particular to a cooling structure of the asynchronous motor, specifically an air-cooled asynchronous motor. The utility model aims to solve the problem that the cooling structure of a traditional air-cooled asynchronous motor is not reasonable enough, specifically the problems that the structure of a cooling system is not even in cooling, low in cooling efficiency or complicated in structure and difficult in manufacturing. The air-cooled asynchronous motor comprises a motor base, a fan and a fan cover, wherein the outer surface of the motor base is fixedly provided with an axial radiating fin; the fan is arranged at the end part of a revolving shaft of the motor; and the fan cover covers the fan and is fixedly connected with an end cover of the motor. The air-cooled asynchronous motor also comprises an outer fan cover fixedly arranged on the outer surface of the motor base; the outer fan cover covers the radiating fin to form a motor external air flue together with the radiating fin; and the air flue is communicated with the air outlet of the fan cover. A gap between the outer fan cover and the fan cover is sealed by a sealing strip. The air-cooled asynchronous motor is reasonable in design and simple in structure.
Description
Technical field
The utility model relates to asynchronous motor, and particularly the cooling structure of asynchronous motor is specially a kind of air-cooled type asynchronous motor.
Background technology
The cooling system of normal asynchronous adopts air as coolant (abbreviation air cooling) usually; Comprise self cooling, he fans cooling system structures such as cold to fan cold-peace certainly; By cooling air flow direction can be divided into axially again, radially hybrid, wherein cold to fan certainly with radial-axial, axial ventilation formula cooling system structure is the most commonly used.
Common cold from fanning, axial ventilation formula Induction Motor Structure is as shown in Figure 1, its cooling system structure mainly comprises support 3, be fixed in axial cooling fin 1 on the support outer surface, be installed in the fan 7 of roller end and be installed in fan 7 outsides and be fixed on the fan housing 5 on end cap 6 cylindricals.In running, cooling air sucks from fan housing 5 inlets, behind passing through fan 7 rotating boostings, blows out the fin 1 of cool motors support 3 outer surfaces from fan housing 5 outlets.But the shortcoming that exists is following: after 1, cooling air blows out from the fan housing outlet, do not blow over fin surface fully, quite a few is lost in the ambient air, makes cooling effectiveness low; 2, when fin is longer, cooling air can't blow to whole fin surface, causes the motor cooling inhomogeneous.
The closed Induction Motor Structure in the outer air channel of band is as shown in Figure 2, and its cooling system structure mainly comprises support 3, fan housing 5 and fan 7, wherein, is furnished with air duct 9 in the support 3.In running, cooling air sucks from fan housing 5 inlets, behind passing through fan 7 rotating boostings, blows out from fan housing 5 outlets, gets into the air duct of arranging in the support 39, and motor is cooled off.Though this kind cooling system structure has effectively been avoided the loss of cooling air quantity; Guaranteed axial Homogeneouslly-radiating; But the shortcoming that exists is following: because motor bed-plate 3 is a foundry goods with end cap 6, particularly support 3 has increased the manufacturing process difficulty because the existence of air duct 9 causes its complex structure; Percent defective is high during fabrication to cause it, makes the motor manufacturing cost increase.
Therefore, be necessary to invent a kind of air-cooled type asynchronous motor with novel cooling structure.
Summary of the invention
The utility model is in order to solve the very not rational problem of existing air-cooled type asynchronous motor cooling structure; Be specially that the cooling system structure inhomogeneous cooling is even, cooling effectiveness low or complex structure, make the problem of difficulty, a kind of air-cooled type asynchronous motor with novel cooling structure is provided.
The utility model is to adopt following technical scheme to realize: a kind of air-cooled type asynchronous motor; Comprise that outer surface is fixed with the support of axial cooling fin, is installed in fan, the fan housing of motor rotary shaft end; Said fan housing covers fan and is connected fixing with End cover for motor; Also comprise the outer fan housing that is fixed on the support outer surface, said outer fan housing covers fin and forms motor external air channel, the air outlet UNICOM of said air channel and fan housing with fin.
During work, cooling air sucks from the air intake vent of fan housing, behind the passing through fan rotating boosting, blows out from the air outlet of fan housing, gets into the air channel of outer fan housing and fin formation, and then cold sink, reaches the purpose of cool motors.
The utility model is reasonable in design, simple in structure, efficiently solves that existing motor cooling system configuration inhomogeneous cooling is even, cooling effectiveness is low or complex structure, makes the problem of difficulty.

Among the figure, 1-fin, the outer fan housing of 2-, 3-support, 4-sealing strip, 5-fan housing, 6-end cap, 7-fan, 8-air channel, 9-air duct, 10-screw.
Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing.
Like Fig. 3, shown in 4, a kind of air-cooled type asynchronous motor comprises support 3; Outer surface at support 3 directly is cast with axial fin 1; Fan 7 is installed in the shaft of motor end, and the outside of fan 7 is equipped with fan housing 5, and fan housing 5 covers fan 7 and is connected fixing with screw with the cylindrical of End cover for motor 6; Outer fan housing 2 usefulness screws 10 are installed in the outer surface of support 3; Can freely dismantle, outer fan housing 2 covers fin 1 and forms motor external air channel 8, the air outlet UNICOM of said air channel 8 and fan housing 5 with fin 1.Be lost in the extraneous air in order farthest to reduce cooling air quantity, improved the cooling effectiveness of cooling system, the gap between outer fan housing 2 and the fan housing 5 is with sealing strip 4 sealings.
During concrete work, cooling air sucks from the air intake vent of fan housing 5, behind passing through fan 7 rotating boostings, blows out from the air outlet of fan housing 5, gets into the air channel 8 of outer fan housing 2 and fin 1 formation, and then cold sink 1.Based on said process, because sealing between outer fan housing 2 and the fan housing 5, cooling air gets into the 8 pairs of fin 1 in air channel and cools off, and cooling air is not lost in the extraneous air and goes, and has improved cooling effectiveness; No matter fin 1 axial length what, cooling air can be blown over the surface of fin 1 fully, and motor is cooled off equably; Support 3 needn't specific placement air channel 8, has reduced the manufacturing process difficulty of support 3, has improved the rate of finished products of support 3, thereby has reduced the manufacturing cost of motor.
