Locomotive vehicle monitoring devices running stocks (
Shaft)
Know how much?

29 when I when a flight attendant, the shaft is not very cold.
At that time, I think this thing all useless, useful, it is also used when I was in on-site parking down touch temperature?
In maintenance when the electrician, I have huge vexed this stuff, because every time repair the shaft must be under the car, put the dirty clothes.
Later, I don't care who in charge of the shaft shall be reported to the technical work, to gradually realize the importance of this gadget.
So, I think it is necessary to popularize the three philosophical questions about shaft quote: shaft to quote?
What's the use?
How does it work?
Shaft is what, what's the use?
Shaft to the locomotive safe running stocks is the one of the most important security equipment.
The locomotive go line department is no small matter, is just an accident, function advanced shaft can courses over the basic guarantee of safety.
All possible shadow to the axis of the quote before, basic and comedian bicycle, except the bell ringing, which is ringing, which is full of false alarms.
But, now in the market mainstream Tang Zhi, shipping shaft basic did not false positives, not only can monitor temperature, also can be used to detect the abnormal vibration.
You can say that, as long as the call the police, the locomotive is running stocks have a problem.
How do you use the shaft to quote?
When the shaft to vibration alarm, you will always hear someone say: this is a false alarm, I get touched, normal temperature.
原谅我吗?
Vibration alarm can you touch them false positives?
？
？
Or when the temperature of the shaft to report to the police, you will hear someone say: this is a false alarm, I get touched, normal temperature (
However, touched the wrong points)
。
Axis usage is very simple: (
1)
SS4B and HXD1 models: each axis has 6 monitoring points and monitoring points to realize two functions: monitoring temperature and vibration monitoring.
Vibration monitoring is the wheel on the rail every week, there will be vibration, that's the cut kaka's voice.
Suppose axle box bearings have shed, the vibration spectrum there is a difference between (
We are listening with ears listen to not to come out)
Vibration analysis is to analyze the spectrum.
Each axis, a total of 6 monitoring points and numbered sequentially driven wheel of the gear end begins to calculate case,
Not from the driver side!
！
！
Not only part of the flight attendants is not clear, part of the maintenance staff also don't know)
。
1 point for axle box bearing and on the pulley tread;
2 points for the traction motor bearings and gear;
3 points for holding shaft bearing;
4 points for holding shaft bearing;
5 points for traction motor free end bearing;
6 for the axle box bearings and there pulley tread.
（
2)
SS4G models: each axis has 6 monitoring points and the order number from the driver side.
Why and SS4B different?
Because, SS4B is unilateral straight tooth, SS4G is bilateral helical.
（
3)
DF4B models: each axis has 6 monitoring points and numbered sequentially driven wheel of the gear end begins to calculate case.
71 on behalf of the main generator;
Before 72 on behalf of the ventilator;
After 73 on behalf of the ventilator.
The shaft to call the police, what should I do?
Because of space factors, after, I will write a shaft to alarm processing method separately.
PS1: type HXD1 locomotive Tang Zhi shaft quote if made in vice the driver side separately on the console panel machine shows axle temperature, according to the 'clear alarm' button to view its axle temperature.
Figure 1 for type HXD1 machine axle to vice machine PS2: shaft is not everything, direction of the inspection have to check,
A shaft to monitor can't cover all running stocks;
The second is abrupt fault;
3 it is technology also has a blind spot)
。
But, we can do nothing without shaft to!
