Rolling bearing, if can choose not wrong to use correctly, can be used for a long time;
The correct selection and correct use of conditions, damage status to stripping.
On the other hand, there are any early damage and yield to the early damage of use;
As the cause of the early damage, using smooth on thinking is not enough, the error of the foreign invasion, which have a bearing device and axis deflection of precision, on the shaft and bearing box, insufficient information seminars, etc.
To say the reason have overlapping the condition of the match.
Rolling bearing fault phenomenon common performance for two kinds, one is the high temperature through the bearing assembly parts, bearing noise during operation.
1, high bearing temperature through, when the host is running gear bearing parts allowed to have a certain temperature, when the hands touch the host shell, should not feel hot as normal, indicate the bearing temperature conversely through high.
Bearing temperature through high reason: smooth oil quality will not agree with the request or metamorphosis, smooth oil stick through high;
Host assembly too tight,
Lack of clearance)
: bearing assembly too tight;
Bearing race on or inside the shell on the axle load is too large;
Or broken roller bearing adhere to rack etc.
2, bearing noise rolling bearing in the work permit have subtle sound operation, if too much noise or abnormal noise or sound hitched ring, indicates there was something wrong with bearing.
The cause of the rolling bearing noise compared complex, one is the bearing inner and outer appearance and wear.
And this kind of wear and tear, damaged bearing and shell, bearing and shaft matching relations, incur axis deviation from the correct position, bearing load are running to produce sound.
When the bearing fatigue, its appearance metal flake;
Also can produce sound make bearing radial clearance increases.
In addition, the lack of bearing is smooth, dry friction, and bearing broken etc all make abnormal noise.
Bearing wear loose after kuang, adhere to the looseness damage, also can produce sound.
In addition to the wrong way,
1)
Change bearing, check for new bearing stop seriously, and the diameter of axle and bearing hole and the rotor to stop careful check;
（
2)
Assembly and disassembly bearings, strict execution repair technology, serious operation, to prevent improper installation of the bearing damage;
（
3)
Fuel oil change in time, ensure the bearing working condition has been in good condition;
（
4)
Check carefully during operation, found hidden trouble trouble, eliminate in a timely manner.
