First, determine the best time to repair bearing

Rolling into the repair work to which state is better ,bearing type ,quantity,level, concentration of production on the whole development of the industy have a significant bearing from the bearing of these laws and characteristics to determine the damage .Use the most damage to small and medium sized bearings,usually rings or rolling fatigue and excessive wear based. When the wear of the bearing rolling surface into the third stage,or pitting and spalling has occurred, then the bearings will quickly become invalid,then the damage to the raceway surface is very serious,very difficult to repair ,repair,or have lost value.

But bearing in the stage before the relatively minor wear,rolling fatigue only in the surface layer under the surface of a few microns to a few microns in depth can occur, and therefore at this time machine will be bearing repair,you can get better with small price repair effect.By mechanical means so that the surface layer of metal plastic deformation in short ,the period of repair of rollong bearings when the bearing had worked for a long period of time,has been fully utilized,and in the damege is repaired prior to entering the entering the most appropriate.

Second, bearing repair method to determine

Bearings shall be the concrete repair service whether judgment method, namely bearing has been make full use of and the concret destruction is near judgment method is as follows:

1) use of bearings working condition monitoring instruments

Using such as iron spectrometer is SPM or the I-or ID-1 type bearings rolling bearing the friction torque according to bearing diameter calculating work condition monitoring instruments to judge the working state of the bearing and decided to bearing when should be effectively, this is the most convenient and reliable method.

For example when use HD-type 1 instrument, when the pointer close to the danger zone by warning, and take measures to improve the lubrication pointer did not return after, it can be judged is bearing itself, right now but has not yet come into the danger area while, bearing effectively. How far away from danger spots on earth began to repair service, can adjust by experience.

To use this instrument, INA double row angular contact ball bearing size specification table can make full use of bearing work potential, timely report will bearing, and can avoid the problem, is safe and economic.

2) use simple tools to monitor

With these instruments in the occasions, the operator can hold round rods or wrench and tools of the most close to bearing conflict machine shell parts, will be ashamed to tools listening ears by the tools of sound from running bearings, and of course use medical stethoscope modification can also.

 
The normal running bearings sound should be even, stable not harsh voice, not the normal running bearings is sound with various kinds of intermittent, imperial deep groove ball bearing R... 1600.. RLS.. RMS.. Closed series impact or harsh voice. First have to get used to the normal running bearings sound, then can hold judgment is not normal running bearings of sound, and then through the practice of the accumulation of experience, and further analysis of what not corresponding to the normal voice what kind of bearing not normal phenomenon. Bearing not normal voice categories many, but difficult to talk, mainly depending on the accumulation of experience.
