Abstract
The invention relates to the motor dustproof technique, in particular to a dustproof device for an alternating current traction motor bearing of a high-power locomotive and solves the technical problem in a current original motor that impurities such as dust in cooling air are easy to enter a transmission end bearing circulation circuit from a traction motor ventilation hole. The dustproof device for the alternating current traction motor bearing of the high-power locomotive is applicable to motors with ventilation holes in inner bearing covers and transmission end covers; the dustproof device comprises an inner cramp and an outer cramp, the inner cramp is arranged at the junction of a ventilation hole and a motor air outlet and used for isolating the ventilation hole and the air outlet, and the outer cramp is arranged at the exit of the ventilation hole; the exit of the ventilation hole is surrounded by the outer cramp, and an opening is formed in a downward side of the outer cramp. According to the dustproof device for the alternating current traction motor bearing of the high-power locomotive, the original structure function requirement can be met, and the problem that the transmission end bearing is polluted by the dust is solved. The structure of the whole device is simple, and the device has an excellent dustproof effect.
Description
Technical field
The present invention relates to traction electric machine dust control technology, be specially a kind of high-power locomotive AC traction electric motor bearing dustproof device.
Background technology
Prototype machine is a kind of High-power AC drives locomotive traction motor, and the type of cooling is forced ventilation, and driving end bearing uses gear case oil to be lubricated.Because negative pressure can be formed during motor bearings high speed rotating in bearing chamber, lubricating oil is caused to overflow at the labyrinth of seal ring, the lubricating oil overflowed not only can pollute motor internal, and gear box lubricating oil can be caused to run off in a large number, in order to prevent the generation of case above, devise passage when designing traction electric machine bearing chamber structure at driving end bearing chamber, make the air pressure in bearing chamber keep balance.
The locomotive operation of prototype machine, in operating modes that dust is more, circuit air ambient is severe such as coal fortune, Ores, after running a period of time, occurs in that some bearing faults, the analysis found that, it is one of major reason causing bearing burnt that bearing oil pollutes.And dust impurities is exactly based on passage and enters into the circulating oil path of motor-driven end bearing, cause the quality of bearing oil by serious destruction, and then directly affect the working environment of driving end bearing.
As shown in Figure 4, motor-driven end lubricating system is that gear wheel rotates the gear box lubricating oil taken up in gear-box, splashes to dynamo oil oil collection box, supplies bearing lubrication, lubricating oil unnecessary in oil collection box returns and stays back gear-box from motor oil leak hole, thus realizes the oil circulation of driving end bearing.This motor is forced ventilation methods for cooling, and cooling wind enters from non-transmision end, by rotor ventilation road, flows out from the air outlet of driving end end cap.But this structure has a disadvantage in that the air outlet of passage adjacent driving end end cap, and the two is mutually communicated at motor internal, dust, impurity that cooling wind carries can deposit at passage for a long time, and a little enters into bearing chamber, takes care of the pence and pollutes bearing lubricant environment.It is thus desirable to the dust guard of a kind of bearing chamber passage improves the running environment of motor bearings, improve the quality of motor bearing lubrication oil in running.
Summary of the invention
The present invention solves that the impurity such as the dust in the cooling wind that current prototype machine exists enter driving end bearing circulating oil path technical problem easily by traction electric machine passage, it is provided that a kind of high-power locomotive AC traction electric motor bearing dustproof device.
The present invention realizes by the following technical solutions: a kind of high-power locomotive AC traction electric motor bearing dustproof device, it is adaptable to inside cap and driving end end cap are provided with the motor of passage；Described dust guard includes being located at passage and motor air outlet intersection for isolating the interior cramp of passage and air outlet and being located at the outer cramp in passage exit；The encirclement of passage exit and the side down are provided with opening by described outer cramp.
For preventing the impurity such as the dust cooling down in wind from entering driving end bearing circulating oil path by traction electric machine passage, driving end end cap installs additional dust guard, directly reduces external dust impurity and enter the probability of motor cycle oil circuit.
Present configuration is under conditions of the casting not changing original bearing with end cover room and processing structure, by increasing some widgets, passage and air outlet are kept apart by interior cramp, prevent the dust in cold wind from accumulating at passage, outer cramp is possible to prevent the dust of outside motor to be entered bearing circulating oil path by passage, both can reach original structure functional requirement, solve again the dust pollution question that driving end bearing is subject to.Whole apparatus structure is simple, and has the most outstanding dust-proof effect.

Detailed description of the invention
A kind of high-power locomotive AC traction electric motor bearing dustproof device, it is adaptable to inside cap 4 and driving end end cap 5 are provided with the motor of passage 6；Described dust guard includes being located at passage 6 with motor air outlet 9 intersection for isolating the interior cramp 10 of passage 6 and air outlet 9 and being located at the outer cramp 11 in passage 6 exit；The encirclement of passage 6 exit and the side down are provided with opening by described outer cramp 11.
Described outer cramp 11 is welded on outside driving end end cap 5 by gusset；Interior cramp 10 is welded on passage 6 and air outlet intersection；Sealing smeared by gap silicone rubber after interior cramp 10 and outer cramp 11 welding.
Passage dust guard is made up of interior cramp, outer cramp and driving end end cap air outlet part muscle, and sealing smeared by the gap silicone rubber of postwelding.As it is shown in figure 1, owing to having 6 air outlets on motor A end end cap, be divided into 2 groups, lay respectively at end cap upper left side and lower right, be close to each air outlet is passage；Dust impurities is easily deposited in passage groove, hence into bearing chamber along with cooling wind.Present invention improves over passage wind path, by opening down for the dust guard mouth of pipe (outer cramp), make cooling wind and walk sector-style and cannot directly pour into, even if entering dust-proof pipeline, dust storm dust is made oneself to drop in utilizing the pipeline of action of gravity cramp outside, reduce sand grains and enter the probability in gross blow hole, the probability that minimizing motor and gear case oil are polluted by foreign matter.The most in a tubular form, side down is provided with opening to outer cramp 11, is used for ventilating, and can effectively prevent the entrance of dust simultaneously.The ventilation diagram of the motor after improvement is as shown in Figure 3.
My company uses this technology, transform motor more than 500 platform run more than 2 years, after running 1 year, the motor ruuning situation after rectification is tracked, and the oily situation of rectification rear gear box lubricating oil is analyzed, 5000 kilometers of oiliness inspection situations of the motor after rectification are substantially better than oil before transformation.Checking Renovation of Dust is effective, respond well.
