Abstract
A motor of shaft cooling type is prepared as setting hollow portion at internal of motor shaft to form hollow motor shaft, sealing blade end of motor shaft to sealed end and setting another end of motor shaft to be hollow end, arranging one or multiple through hole at fixing position of blade and motor shaft, connecting said through hole to hollow portion of motor shaft and air guiding space of blade for making air at hollow portion of motor shaft flow continuously so as to achieve purpose of heat radiation.
Description
One. technical field
The present invention relates to a kind of motor.
Two. background technology
Motor in the market because in use the high speed rotating of motor internal can make that the motor feels hot, thereby need cool off motor.Usual way is to adopt the fan blade heat radiation, though reach the purpose of heat radiation, but the effect of heat radiation is unsatisfactory, generally the motor feels hot is to produce from motor internal, and the sealing of motor also is very important, because the sealing of motor has influenced the heat radiation of motor again, make the heat of motor internal be difficult for shedding, thereby the inner heat problem of people when seeking a kind of sealing that can keep motor always and can solve machine operation again, to improve the operating efficiency of motor, prolong the useful life of motor bearings.
Three. summary of the invention
The objective of the invention is to: design a kind of novel motor, make motor the time be easy to heat radiation, reach and make the automatic good cooling effect of motor, the purpose that prolongs the useful life of motor in work.
The present invention adopts following structure to realize above-mentioned purpose: a kind of shaft cool electric machine, comprise stator, rotor, motor housing, bearing, fan blade, motor shaft inside is provided with hollow position, form the core motor axle, be positioned at motor shaft one end hollow position sealing the becoming sealed end of fan blade one end, motor shaft other end hollow position is a hollow end, in fan blade and motor shaft bearing, be provided with one or more through holes, through hole is communicated with the wind-guiding space of motor shaft hollow position and fan blade, the wind-guiding space is between fan blade, and hollow position is used to hole and hollow end all; The motor shaft hollow end is provided with screen pack; The motor shaft sealed end that is positioned at fan blade one end adopts the sealed screw sealing.
Adopt as above structure, well solved the heat dissipation problem in the machine operation, when machine operation, because the centrifugal force of fan blade, constantly enter the hollow end of motor shaft along with the cool breeze of motor shaft electric rotating machine outside, enter into wind-guiding space between the fan blade through the hollow position of motor shaft from through hole, the continuous rotation of fan blade makes the hot blast in wind-guiding space be discharged to outside the motor again, because the outer cold wind of motor can flow into by the hollow position of motor shaft in the motor, can take out of outside the motor shaft by the rotation of fan blade again simultaneously, thereby can with in the motor by bearing, stator, the heat of generations such as rotor is discharged to outside the motor, has well solved the heat dissipation problem of motor internal.
Motor constantly flows the air at motor shaft hollow core place at work by its internal structure, reaches the purpose of heat radiation; Because the centrifugal action of fan blade, when motor rotation, the air of motor and motor shaft hollow position is constantly understood by the centrifugal force sucking-off of fan blade, thereby reaches desirable heat radiation purpose.
Four. description of drawings
The generalized section of Fig. 1 motor
The A-A of Fig. 2 Fig. 1 cuts open
Five. embodiment
As shown in the figure, shaft cool electric machine comprises: motor housing 7, spindle 8, rotor 9, bearing 12, fan blade 2, core motor axle 6, fan housing 1, screen pack 11.
Motor shaft inside is provided with hollow position 5, form core motor axle 6, motor shaft 6 one end hollow positions 5 sealings that are positioned at fan blade 2 one ends become sealed end 4, motor shaft 6 other end hollow positions are hollow end 10, in fan blade 2 and motor shaft 6 bearings, are provided with one or more through holes 3, in the present embodiment two through holes 3, through hole 3 is communicated with the wind-guiding space 13 of motor shaft 6 hollow positions 5 and fan blade 2, and wind-guiding space 13 is between fan blade 2, and hollow position 5 is used to hole 3 and hollow end 10 all; Motor shaft 6 hollow end 10 are provided with screen pack 11; The sealed end 4 that is positioned at the motor shaft 6 of fan blade 2 one ends adopts the sealed screw sealing.
When motor rotation, spindle 8, rotor 9, bearing 12 can produce a large amount of heats, the part of these heats is taken out of motor by extraneous air by the rotation of fan blade 2, after some air that is then entered from motor shaft 6 hollow end 10 screen packs 11 by the outside flows through hollow shaft hollow position 5, also taken to outside the motor from the wind-guiding space 13 that through hole 3 flows between the fan blade 2 by fan blade 2, make motor obtain cooling internally, thereby reach the purpose of quick heat radiating.
The screen pack 11 at hollow end 10 places of motor shaft 6 can prevent the foreign material in the motor shaft outer air to enter the hollow position 5 of motor shaft.
