Description
Technical field
The present invention relates to traction electric machine dust control technology, specially a kind of dust-proof dress of high-power locomotive AC traction electric motor bearing
Put.
Background technology
Prototype machine is a kind of High-power AC drives locomotive traction motor, and the type of cooling is forced ventilation, driving end axle
Hold and be lubricated using gear case oil.Because motor bearings can form negative pressure when rotating at a high speed in bearing chamber, cause to lubricate
Oil overflows at the labyrinth of seal ring, and the lubricating oil of spilling can not only pollute motor internal, and gear box lubricating oil can be caused big
Amount is lost in, and in order to prevent the generation of case above, is devised when designing traction motor bearings cell structure in driving end bearing chamber
Passage, the air pressure in bearing chamber is set to keep balance.
The locomotive operation of prototype machine is in the operating mode that dust is more, circuit air ambient is severe such as coal fortune, ore, operation one
After the section time, there are some bearing faults, the analysis found that, bearing lubrication oily pollution is to cause the important original of bearing burnt
Therefore one.And dust impurities are exactly based on the circulating oil path that passage enters motor transmission end bearing, cause bearing oil
Quality by serious destruction, and then directly affect transmission end bearing working environment.
As shown in figure 4, motor driving end lubricating system is the gear box lubricating oil that gear wheel rotation takes up in gear-box, fly
Splash to dynamo oil oil collection box, supply bearing lubrication, unnecessary lubricating oil, which is returned from motor oil leak hole, in oil collection box stays back gear
Case, so as to realize the oil circulation of transmission end bearing.The motor is forced ventilation methods for cooling, and cooling wind enters from non-transmision end
Enter, by rotor ventilation road, flowed out from the air outlet of driving end end cap.But this structure has the disadvantage that：Passage is tight
The air outlet of driving end end cap is suffered, and the two is mutually communicated in motor internal, dust, the impurity of cooling wind carrying can be logical
Stomata director's time deposits, and a little enters bearing chamber, takes care of the pence and bearing lubrication environment is polluted.Therefore one is needed
The dust guard of kind of bearing chamber passage improves the running environment of motor bearings, improves the product of motor bearing lubrication oil in operation
Matter.
The content of the invention
The present invention is led to solve the impurity such as the dust in the existing cooling wind of current prototype machine easily by traction electric machine
Stomata enters transmission end bearing circulating oil path technical problem, there is provided a kind of dust-proof dress of high-power locomotive AC traction electric motor bearing
Put.
The present invention is realized using following technical scheme：A kind of dust-proof dress of high-power locomotive AC traction electric motor bearing
Put, the motor of passage is provided with suitable for inside cap and driving end end cap；The dust guard includes being located at passage
It is used to isolate the interior cramp of passage and air outlet with motor air outlet intersection and is located at the outer cramp in passage exit；
Passage exit is surrounded and is provided with opening in side directed downwardly by the outer cramp.
Transmission end bearing circulating oil path is entered by traction electric machine passage to prevent from cooling down the impurity such as the dust in wind,
Install dust guard on driving end end cap additional, directly reduce the probability that external dust impurity enters motor cycle oil circuit.
Structure of the present invention is not under conditions of the casting of original bearing with end cover room and processing structure is changed, by increasing
Widget, interior cramp keep apart passage and air outlet, prevent the dust in cold wind from accumulating at passage, and outer cramp can be with
Prevent the dust of outside motor from entering bearing circulating oil path by passage, both can reach original structure functional requirement, and solved biography again
The dust pollution question that moved end bearing is subject to.Whole device is simple in construction, and has very outstanding dust-proof effect.
Brief description of the drawings
Fig. 1 is provided with the external structure schematic diagram of the motor bearing cover of passage.

1- non-transmision end end caps, 2- stators, 3- rotors, 4- inside caps, 5- driving end end caps, 6- passages, 7- bearings
Accumulator, 8- grease oil boxs, 9- air outlets, cramp in 10-, the outer cramps of 11-.
Embodiment
A kind of high-power locomotive AC traction electric motor bearing dustproof device, suitable for inside cap 4 and driving end end cap 5
It is provided with the motor of passage 6；The dust guard is logical for isolating with the intersection of motor air outlet 9 including being located at passage 6
The interior cramp 10 of stomata 6 and air outlet 9 and the outer cramp 11 for being located at the exit of passage 6；The outer cramp 11 is by passage 6
Exit surrounds and is provided with opening in side directed downwardly.
The outer cramp 11 is welded on the outside of driving end end cap 5 by gusset；Interior cramp 10 is welded on passage 6 and air-out
On mouth intersection；Gap after interior cramp 10 and outer cramp 11 welding is smeared with silicon rubber to be sealed.
Passage dust guard is made up of interior cramp, outer cramp and driving end end cap air outlet part muscle, the gap of postwelding
Smeared and sealed with silicon rubber.As shown in figure 1, due to there are 6 air outlets on the end cap of motor A ends, it is divided into 2 groups, respectively positioned at end cap
Upper left side and lower right, be close to each air outlet is passage；Dust impurities are recessed as cooling wind is easily deposited in passage
At groove, hence into bearing chamber.Present invention improves over passage wind path, by the dust guard mouth of pipe（I.e. outer cramp）It is opening down,
Cooling wind can not be directly poured into walking sector-style, even if into dust-proof pipeline, made using Action of Gravity Field in the pipeline of outer cramp
Dust storm dust oneself drops, and reduces the possibility that sand grains enters in gross blow hole, reduces motor and gear case oil is dirty by foreign matter
The probability of dye.Substantially in a tubular form, side directed downwardly is provided with opening to outer cramp 11, for divulging information, while can effectively prevent dust
Entrance.The ventilation diagram of motor after improvement is as shown in Figure 3.
My company uses the technology, has transformed the platform of motor more than 500 run more than 2 years, after after running 1 year to rectification
Motor operation situation be tracked, and to rectify and improve rear gear box lubricating oil oily situation analyze, the motor after rectification
5000 kilometers of oiliness inspection situations are substantially better than oil before transformation.Verify that Renovation of Dust is effective, work well.
