First, some device in using TIMKEN bearing of when on its itself of tour gap problem requirements of special strictly, if tour gap had large, even slightly a points large words, on will easy makes device of parts wear, so had to by reduces tour gap to solution this problem, but with of of another problem and appears has, that is tour gap too small words, thermal of problem, thermal if improper, on will is easy led to internal temperature rise eventually cause bearing overheating and burn!
Second may be too much load (preload). Excessive speed. Clearance is too small. Water or other foreign bodies penetrated. If none of the above two cases is the poor accuracy of the shaft, housing, the deflection of the shaft. See here, I think everyone would like to know the way to solve it, first of all, to research on lubricant and lubrication method, selected for TIMKEN deep groove ball bearing lubricant, and its usage and selection of the correct bearing. Research to meet and bearing clearance and preload, and improved sealing device. Check the accuracy of the shaft and housing. Of course, if you are next to the experts, his actions follow you best!
1 and bearing cleaning
When removing bearings under repair, the first recorded appearance of deep groove ball bearing, confirm that the residual amount of lubricant, after sampling check of lubricant, wash the bearing. As a cleaning agent, general use gasoline, kerosene.
Removed bearing cleaning, cleaning rough and fine finishing and washing, respectively in the container, put a metal mesh bottom, bearing no direct contact with containers of dirt. Coarse cleaning, if the bearings with filth rotate will damage bearing rolling surface, should pay attention to. In cleaning crude oil, using the brush cleared of grease, sticky, away, turn to finish washing.
Precision wash, deep groove ball bearings is in cleaning oil, rotate and carefully cleaned. In addition, cleaning oil should always be kept clean.
2, bearing maintenance and judgment
Used to determine whether the bearing can be removed, and then, to check after bearing wash, carefully check the Raceway surface, rolling surface, the status of the mating surfaces, cage wear, bearing clearance increases and there's no falling damage, abnormal size precision. Non-separation-ball bearing, inner ring with one hand supporting level, rotating outer ring to confirm fluency.
Separation-bearing tapered roller bearings, rolling element and the Raceway in the outer ring can be respectively checked.
Larger bearings cannot rotate, check rolling, rolling road, cage, wall surface appearance, bearing the importance of as high as possible shall be carefully inspected.
