Abstract
The utility model provides a wire winding type motor collecting ring ventilation structure, it is main includes sleeve, brush device, sliding ring, sleeve hot jacket is installed in electric motor rotor epaxially, and the sliding ring is along the telescopic axle to arranging and install an organic whole become with the hub insulation that on brush device installed bearing end plate, the fan was installed on the flange of sleeve (1) bottom for sliding ring and brush device all are located the side of fan, install bearing end plate with the collecting ring cover again on, the air outlet sets up in collecting ring cover bottom, and the air intake setting is in the cover of the collecting ring with fan homonymy side. The air outlet is in under the sliding ring. The utility model discloses with fan direct mount to collecting ring sleeve lower extreme, one has not only practiced thrift the axial installation size but also can follow the collecting ring and directly has inhaleed outward cooling air, directly blow to the sliding ring with cooling air on, reduced the sliding ring temperature effectively, measurement sliding ring temperature only is 60 DEG C of left and right sides during normal operating, wind resistance loss has been reduced simultaneously. Two can suitably increase fan outer diameter, increase the air volume.
Description
Technical field
This utility model belongs to technical field of motor manufacture, is specifically related in the collector ring of winding-type three-phase asynchronous motor
Aeration structure.
Background technology
Winding-type three-phase asynchronous motor is assembled with collector ring at non-shaft stretching end, and its effect is to be filled by slip ring and brush
Put and rotor current is drawn out in rotor junction box, rotor current is received by rotor junction box water resistance starting cabinet again and comes real
The soft start of existing motor.Owing to common collector ring Design of ventilation is collector ring first to cool down fan hot jacket to rotor main shaft,
Installing collector machine (as shown in Figure 2) the most again, fan dimension so can be made too small, in collector ring, wind path circulation is not smooth, the
One causes collector ring slip ring temperature too high, and when motor runs, slip ring temperature reaches about 105 DEG C；Second carbon dust should not get rid of current collection
Outside ring, 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 report
Useless.This type of fault generation motor accounts for the 50% of same model motor, each 8000 yuan of left sides of fault cause the user direct economic loss
The right side, cause user to stop production about 1 time-of-week simultaneously, the biggest economic loss of cause the user.So solving wound motor collection
Electricity ring ventilation and heat problem is the most urgent problem.
Utility model content
This utility model provides a kind of wound motor collector ring aeration structure, thoroughly changes former collector ring draft type,
Solve collector ring and be in operation that slip ring temperature is too high, carbon dust is difficult to discharge the problem outside collector shell.
For achieving the above object, this utility model adopts the technical scheme that:
A kind of wound motor collector ring aeration structure, mainly includes sleeve, brushgear, slip ring, and sleeve hot jacket is installed
On rotor axis of electric, slip ring is axial arranged along sleeve and integrally mounted with hub insulation, and brushgear is installed to bearing end
Covering, 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 will collection
Electricity ring cover is installed on bearing (ball) cover；Air outlet is arranged on bottom collector shell, and air inlet is arranged on and the current collection of fan homonymy
Ring cover side.
Described air outlet is in immediately below slip ring.
Fan be to be mounted directly to collector ring sleeve lower end by this utility model, one not only saved axially mounted size and
And cooling air can be directly sucked in from collector ring, cooling air is directly blown onto on slip ring, significantly reduces slip ring temperature
Degree, measures slip ring temperature and is only about 60 DEG C time properly functioning；Reduce windage loss simultaneously.Two can suitably add big fan
Outside dimension, increases ventilation.
Hot-air after heat exchange is directly discharged collector shell below slip ring by this utility model, the most also band leakage of electricity
The carbon dust produced after brush friction, it is to avoid carbon dust deposition in collector ring, uses wound motor of the present utility model, slip ring
Between be short-circuited the most never again " blowing out " accident, improve the reliability service of wound motor collector ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structure and the circulation wind path schematic diagram of prior art.
Detailed description of the invention
1 pair of this utility model further illustrates 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)
1. a wound motor collector ring aeration structure, mainly includes that sleeve, brushgear, slip ring, sleeve hot jacket are installed on
On rotor axis of electric, slip ring is axial arranged along sleeve and integrally mounted with hub insulation, and brushgear is installed to bearing (ball) cover
