Abstract
The invention discloses a radiating device of a vertical motor, and relates to the field of motors. The radiating device is characterized in that an air channel (7) is arranged between an inner base ring (5) and an outer base ring (6) of a base (1) of the radiating device, the wall of the outer base ring (6) at the lower end of the air channel (7) is communicated with an air inlet hole (8), and the upper end of the air channel (7) is communicated with a through hole (9) of an upper end cover. The radiating device has the advantages that large quantities of required air sources can flow into the air inlet hole in the wall of the outer base ring during running and can flow into a centrifugal fan from the air channel of the base and the through hole of the upper end cover, and accordingly the surfaces of the vertical motor can be effectively cooled.
Description
Technical field
Patent of the present invention relates to machine field, especially a kind of vertical type motor heat abstractor.
Background technology
Existing heat abstractor generally adopts common centrifugal blower to carry out cooling to motor, and common centrifugal fan noise is large, vibration is large, volume is large, air quantity is little, blast is low, can not adapt to the development of modern industry completely.Its defect have following some:
A. the drive motors of common centrifugal blower is installed in spiral case single shaft in 90 °, single flange cantilever type, what matched is again common serial motors, noise is large, vibration is large, particularly powerful centrifugal blower, due to motor own wt, there is a lot of centrifugal blower in use deformed damaged, cause great fame to lose and economic loss to enterprise.
What c. the drive motors of common centrifugal blower was matched is common serial motors, and its rotating speed is generally about 2900r/min, and air quantity is little, blast is low, the high heat that variable frequency high-speed motor produces cannot be taken away, and effectively forces cooling to high-speed electric expreess locomotive.
Summary of the invention
The object of this invention is to provide a kind of structure simple, between the support inner ring and outer ring of motor, be provided with the vertical type motor heat abstractor in air channel.
Employing technical scheme of the present invention, comprises the support of vertical machine, is respectively fitted with upper end cover and bottom end cover at the upper and lower end of its support; The rotating shaft of vertical machine through the impeller assembling centrifugal blower after upper end cover centre bore, and is engaged with locking nut at axle stretch end external screw thread; Be provided with air channel between the support inner ring of support described in it and support outer ring, the support collar wall of lower end, air channel communicates with fresh air inlet, upper end communicates with the through hole of upper end cover.
The present invention arranges air channel by means of support inner ring and support outer ring, a large amount of wind regime enters from the enterprising air holes of support collar wall, the wheel speed of centrifugal blower is high, and the Wind Volume produced, high blast directly carry out pressure cooling to motor, and effetive zone is walked motor and additionally to be generated heat produced heat; Adopt shaft extension at right angle setting mode upwards, the axial force of impeller and rotor is formed holding, and reduces the features such as axial force about 70%.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is sectional structure schematic diagram of the present invention.
In figure: 1-support 2-locking nut 3-impeller 4-centrifugal blower 5-support inner ring
7-air channel, 6-support outer ring 8-fresh air inlet 9-through hole.
Embodiment
See Fig. 1, comprise the support 1 of vertical machine, be respectively fitted with upper end cover and bottom end cover at the upper and lower end of its support 1; The rotating shaft of vertical machine through the impeller 3 assembling centrifugal blower 4 after upper end cover centre bore, and is engaged with locking nut 2 at axle stretch end external screw thread; Be provided with air channel 7 between the support inner ring 5 of support 1 described in it and support outer ring 6, support outer ring 6 wall of lower end, air channel 7 communicates with fresh air inlet 8, upper end communicates with the through hole 9 of upper end cover.
A large amount of wind regimes required when the present invention runs all enter from lower end, vertical machine support outer ring 6 fresh air inlet 8, and enter centrifugal blower 4 by support air channel 7 and upper end cover through hole 9, the surface temperature of vertical motor carries out effective cooling.
Claims (1)
1. a vertical type motor heat abstractor, the upper and lower end comprising the support (1) of vertical machine is respectively fitted with upper end cover and bottom end cover; The rotating shaft of vertical machine through the impeller (3) assembling centrifugal blower (4) after upper end cover centre bore, and is engaged with locking nut (2) at axle stretch end external screw thread; It is characterized in that being provided with air channel (7) between the support inner ring (5) of described support (1) and support outer ring (6), support outer ring (6) wall of air channel (7) lower end communicates with fresh air inlet (8), upper end communicates with the through hole (9) of upper end cover.
