many customers in the warranty on bearings and repair always grasp the timing is not accurate, today linqing hai bearing manufacturing co., the current information will be in the focus of experts to tell you about how to determine the timing of repair, so that in the most critical moment to save the bearing life.
first, determine the best time to repair the bearings
3056 bearing state to work to repair what is better, damage patterns and characteristics which to judge from the bearing. use the most amount of damage to small and medium sized bearings, usually fatigue and excessive wear rings or rolling elements based. when the 3056 bearing rolling surface into the third stage wear, or pitting and spalling, the 3056 bearing will soon become invalid, then the destruction of the raceway surface has been very serious, very difficult to repair, or have lost repair value.
however, bearing in 3056 prior to the above stage, relatively minor wear and fatigue may occur only in the depth of the lower surface of the rolling surface layer several microns to tens of microns, and therefore at this time machine bearing repair, you can use a small price to obtain more good repair effect. in summary, the repair of the rolling bearing when the bearing has worked with for a long period of time, has been fully utilized, but before the damage is repaired enter the most appropriate.
second, bearing repair method for determining the timing of the report
bearing specific method for determining whether it should repair, that bearing has been close to full use and specific method for determining damage appears as follows:
1) the use of bearing working condition monitoring equipment
spm spectrometer or use such as iron or i-id-1 bearing working condition monitoring equipment to determine when the bearing operating status and the decision should be bearing repair, which is the most convenient and more reliable method.
for example, when using the hd-1 type instrument, when the pointer approaching the danger zone from the warning area, and in the improved lubrication and other measures taken did not return a pointer, it can ascertain the bearing itself is the problem, then you can take advantage of not yet entered the danger zone when the bearing repair. exactly how far away from the danger zone begin to repair, by experience adjustments.
with such equipment, can take advantage of the bearing potential, bearing repair promptly and avoid failure, it is safe and economical.
2) the use of simple tools to monitor
in no case have the above instrument, the operator can hand-held tools such as rod or wrench conflict closest to the bearing shell machine parts, listening ear ashamed by the tool came running bearings sound on tools, of course, can also be modified using a medical stethoscope ʱ??
normal bearing operation sound should be uniform, smooth sound without harsh without the normal operation of the bearing, there are a variety of intermittent sound, impact or harsh sound. first used the normal bearing operation sound, then can take to determine the normal bearing operation sound, followed by the accumulated practical experience, we can further analyze what kind of unusual sounds correspond to what kind of bearing on irregularities. many bearing abnormal sound categories, it is difficult to explain in words, mainly by accumulation of experience.
