In addition, when the external load on the bearing and does not rotate, due to external vibration can cause the bearing inner ring raceway indentation, over time will lead to the raceway flaking, peeling debris is more harmful to the bearing, in order to prevent these incidents occurrence in the daily work, effective methods can be used to eliminate the vibration source and vibration, maintain good lubrication, the bearing can be applied to the initial light load, the rolling body in good contact with the roll, to improve the ability of seismic also with the hole in the instal?With the gap effect, the gap between the shaft and the shaft is too large, the relative movement between the two, one with the shaft section of the gap increasing excessive wear, leading to bearing failure: two of the bearing cracks, impact accuracy of movement. These causes of premature backing bearings failures are detrimental to our actual work, so study how to avoid premature bearing failure and prolong life is very practical value.
2 How to avoid premature bearing failure
To prevent premature bearing failure is the most effective way to avoid the above analysis of these factors contribute to a variety of factors and conditions: First, the bearing should be selected prior to use, taking into account the size of the noise, the size of the rigid, bearing radial fissures size, the size of rotational torque. Choice of lubricant, according to the bearing of the work environment, the type of lubricant in use produce different media noise. Such as grease lubrication oil lubrication noisy than the more well-lubricated bearings is to extend the life of the first condition. Use lubricated properly, can improve the accuracy of the smooth movement, but also can play a vibration absorbing buffer, reducing wear and tear effect. However, in the actual work which, bearing and lubrication quarter pollution is inevitable. The most common is the use of the protective cover can not completely prevent the relative movement of dust and stolen intrusion. However, the relative movement of inner and outer rings can not completely prevent contamination of the bearing, if the bearing is contaminatedlation misalignment will cause bearing failure.
