Description
Technical field
A kind of motor shaft end of this utility model gap dust guard, is related to the dust guard device use on a kind of motor,
Belong to motor device field.Particularly to a kind of, motor shaft end gap is carried out with dust-proof, the device of raising motor service life.
Background technology
The working environment of motor is often relatively more severe, and the in the air around motor contains a lot of solid particles and dust,
These dusts not only can block the air vent of motor after entering motor, so that motor cannot be radiated, also can be to two on motor shaft
Bearing impacts, once bearing damage can cause stator mutually to grind heating with rotor, and then burns out coil, so that motor cannot be made
With so having to motor is carried out dust-proof, existing motor is dust-proof mostly only to be installed filter screen additional to the cooling air inlet of motor and enter
Row is dust-proof, but dust also can enter from motor shaft end gap, motor is caused damage, so having to motor shaft end gap
Carry out dust-proof, existing dust-proof device is carried out to motor using sealing shell although the anti-dust performance of this method very well, but
It is not only to involve great expense, and operating cost is also very high, be not easy to promote the use of, and adopt rubber seal that motor shaft end is stitched
Gap carries out dust-proof method, and after a protracted use, the rotation of motor shaft can cause to rubber seal to wear and tear, dust-proof effect
Can worse and worse.
Content of the invention
In order to improve above-mentioned situation, a kind of motor shaft end of this utility model gap dust guard provide a kind of to motor shaft
End gap carries out dust-proof, the device of raising motor service life.Structure is simple, convenient use.
A kind of motor shaft end of this utility model gap dust guard is realized in：A kind of motor shaft end of this utility model
Gap dust guard by electric machine casing, palm fiber brush, retainer ring, dust-proof gasket ring, mounting ring, internal helical blades, motor shaft, sleeve and
Fixing bolt forms, and retainer ring is placed on electric machine casing, and sleeve is placed in the middle part of retainer ring, and mounting ring is placed on sleeve outer wall,
Dust-proof cushion ring set is placed on sleeve outer wall, and is located between mounting ring and retainer ring, and mounting ring uniformly has three installing holes,
Three installing holes are uniformly had on retainer ring, and corresponds with three installing holes in mounting ring, the installing hole in mounting ring
And the installing hole in retainer ring between, fixed using fixing bolt, palm fiber brush is placed on one end of sleeve lining, internal helical blades
It is placed in sleeve lining.
During use, only electric machine casing need to be arranged on existing motor, motor shaft is passed from sleeve, and and palm fiber brush
Contact, motor rotates, the palm fiber brush spin friction of motor shaft and sleeve lining produces electrostatic, under the absorption of electrostatic, enter
Dust in motor shaft end gap is adsorbed, and dust is collected in sleeve, and adsorbs on motor shaft, and motor shaft rotarily drives
The dust synchronous rotary of absorption on motor shaft, dust rotates, the internal helical blades of sleeve lining is extruded simultaneously, due to making
The firmly relation with counteracting force, internal helical blades promote dust to move along the space between internal helical blades, and dust is finally from interior
Motor shaft gap is discharged in space between helical blade, as long as keeping internal helical blades direction of rotation and the rotation direction of motor shaft
It is contrary, you can play the dust-proof of motor shaft end gap well, reach and motor shaft end gap is carried out with dust-proof, raising motor
The purpose of service life.
Beneficial effect.
First, structure is simple, convenient and practical.
2nd, with low cost it is easy to promote.
3rd, the service life of motor can be improved.
Brief description
Accompanying drawing 1 is a kind of structural representation of motor shaft end of this utility model gap dust guard.
In accompanying drawing
Wherein part is：Electric machine casing（1）, palm fiber brush（2）, retainer ring（3）, dust-proof gasket ring（4）, mounting ring（5）, interior spiral shell
Vane piece（6）, motor shaft（7）, sleeve（8）, fixing bolt（9）.
Specific embodiment：
When a kind of motor shaft end of this utility model gap dust guard is achieved in that use, only need to be by electric machine casing
（1）It is arranged on existing motor, by motor shaft（7）From sleeve（8）Pass, and and palm fiber brush（2）Contact, motor rotates,
Motor shaft（7）And sleeve（8）The palm fiber brush of inwall（2）Spin friction produces electrostatic, under the absorption of electrostatic, enters into motor shaft
（7）Dust in the gap of end is adsorbed, and dust is collected at sleeve（8）Interior, and adsorb in motor shaft（7）On, motor shaft（7）Rotation
Drive motor axle（7）The dust synchronous rotary of upper absorption, dust rotates, simultaneously to sleeve（8）The internal helical blades of inwall（6）Enter
Row extruding, due to the relation of active force and counteracting force, internal helical blades（6）Promote dust along internal helical blades（6）Between sky
Gap moves, and dust is finally from internal helical blades（6）Between space discharge motor shaft（7）Gap, as long as keep internal helical blades
（6）Direction of rotation and motor shaft（7）Rotation direction be contrary, you can play motor shaft well（7）Hold the dust-proof of gap,
Reach to motor shaft（7）End gap carries out dust-proof, the purpose of raising motor service life.
