Abstract
A kind of wound motor collector ring aeration structure, mainly include sleeve, brushgear, slip ring, sleeve hot jacket is installed on rotor axis of electric, slip ring is axial arranged along sleeve and integrally mounted with hub insulation, brushgear is installed on bearing (ball) cover, fan is installed on the flange of sleeve (1) bottom so that slip ring and brushgear are respectively positioned on the side of fan, then are installed on bearing (ball) cover by collector shell；Air outlet is arranged on bottom collector shell, and air inlet is arranged on the collector shell side with fan homonymy.Described air outlet is in immediately below slip ring.Fan be to be mounted directly to collector ring sleeve lower end by the present invention, one has not only saved axially mounted size but also can be directly sucked in cooling air from collector ring, cooling air is directly blown onto on slip ring, significantly reduces slip ring temperature, measure slip ring temperature time properly functioning and be only about 60 DEG C；Reduce windage loss simultaneously.Two can suitably strengthen outer diameter fan size, increase ventilation.
Description
Technical field
The invention belongs to technical field of motor manufacture, ventilate in being specifically related to the collector ring of winding-type three-phase asynchronous motor knot
Structure.
Background technology
Winding-type three-phase asynchronous motor is assembled with collector ring at non-shaft stretching end, and its effect is will by slip ring and brushgear
Rotor current is drawn out in rotor junction box, rotor current is received by rotor junction box water resistance starting cabinet again and realizes electricity
The soft start of machine.Owing to common collector ring Design of ventilation is collector ring first to cool down fan hot jacket to rotor main shaft, then
Installing collector machine (as shown in Figure 2) again, fan dimension so can be made too small, in collector ring, wind path circulation is not smooth, and first makes
Becoming collector ring slip ring temperature too high, when motor runs, slip ring temperature reaches about 105 DEG C；Second carbon dust should not get rid of collector ring
Outward, often result in the generation of short circuit " blowing out " accident between slip ring, make insulation breakdown between slip ring and sleeve, make collector ring scrap.
This type of fault generation motor accounts for the 50% of same model motor, each fault cause the user direct economic loss about 8000 yuan,
Cause the user to stop production about 1 time-of-week, the biggest economic loss of cause the user simultaneously.So solving wound motor collector ring
Ventilation and heat problem is the most urgent problem.
Summary of the invention
The present invention provides a kind of wound motor collector ring aeration structure, thoroughly changes former collector ring draft type, solves current collection
Ring is in operation, and slip ring temperature is too high, carbon dust is difficult to discharge the problem outside collector shell.
For achieving the above object, the present invention adopts the technical scheme that:
A kind of wound motor collector ring aeration structure, mainly includes that sleeve, brushgear, slip ring, sleeve hot jacket are installed on electricity
On machine rotor axle, slip ring is axial arranged along sleeve and integrally mounted with hub insulation, and brushgear is installed on bearing (ball) cover,
Fan is installed on the flange of sleeve (1) bottom so that slip ring and brushgear are respectively positioned on the side of fan, then by collector shell
It is installed on bearing (ball) cover；Air outlet is arranged on bottom collector shell, and air inlet is arranged on the collector shell side with fan homonymy
Face.
Described air outlet is in immediately below slip ring.
Fan be to be mounted directly to collector ring sleeve lower end by the present invention, one not only saved axially mounted size and also can
To be directly sucked in cooling air outside collector ring, cooling air is directly blown onto on slip ring, significantly reduces slip ring temperature, just
Measure slip ring temperature when often running and be only about 60 DEG C；Reduce windage loss simultaneously.Two can suitably strengthen outer diameter fan
Size, increases ventilation.
Hot-air after heat exchange is directly discharged collector shell below slip ring by the present invention, the most also takes away brush and rubs
The carbon dust produced after wiping, it is to avoid carbon dust deposition in collector ring, uses the wound motor of the present invention, basic between slip ring
Be short-circuited " blowing out " accident never again, improves the reliability service of wound motor collector ring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is structure and the circulation wind path schematic diagram of prior art.
Detailed description of the invention
1 the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of wound motor collector ring aeration structure, including collector shell 3, sleeve 1, brushgear
4, slip ring 2, observation window 5, fan 6, air inlet 7, air outlet 8, bearing (ball) cover 9.
First insulation will be used between slip ring 2 and sleeve 1 to separate, between slip ring and slip ring, uses insulation blanket stud axial restraint,
Sleeve 1 and slip ring 2 are fixed into an entirety, convenient installation or removal；Then sleeve 1 hot jacket is installed on rotor axis of electric.
Brushgear 4 is installed on bearing (ball) cover 9, and regulates brush standing screw and make brush-center line just to slip ring 2 centrage.By wind
Air outlet 8 closing on the flange bottom sleeve 1, is first installed to bottom collector shell 3 with bolt by fan 6, and air inlet 10 is arranged
In collector shell 3 side with fan 6 homonymy；Make the cold wind come in from air inlet 10 enter collector shell 3 top, then divide
Dissipating and enter between each slip ring 2, after cooling slip ring 2 and brushgear 4, hot blast is discharged from air outlet 8.Collector shell 3 is installed again arrive
On bearing (ball) cover 9, wind deflector and air inlet 7 are finally installed on collector shell 3 collector shell 3.After rotor rotates, band
Dynamic collector ring sleeve rotates together with slip ring, and together with fan and sleeve are put together on by bolt, sleeve also drives fan to rotate, shape
Becoming to circulate wind path as shown by the arrows in Figure 1, the heat making slip ring produce in running is discharged to current collection below collector ring
Outside ring cover.
Described air outlet 8 is in immediately below slip ring 2.Hot blast can take away brush and slip ring operation when discharging time, friction produces
Carbon dust.
Claims (2)
