SKF deep groove ball bearings are common failure handling and noise elimination method

In General, if the proper use of SKF bearings, you can use up to reach fatigue life. But there will be accidents injury prematurely, cannot use situation. This early injury, and fatigue life of a relative, is referred to as the quality limits of failures or accidents. Installed, used, lubrication of origin does not note that foreign objects from external intrusion, axis, case study on thermal effect of insufficient, and so on.
　　The first bearing manufacturing-related noise: including noise and vibrato here, when the SKF bearing rotating due to vibration of cage and cage and rolling elements impact will produce sound. sound cyclical. vibrato has certain frequencies of sound, is due to the larger on the Raceway surface waviness causes arising from vibration. This is the most common problem, we need to pay more attention in the future can.
　　Second using improper caused of noise: for various SKF bearing are exists. Dang bearing roll road surface or scroll body surface was touch injury, and pressure pit, and rust, then on will produced has must cycle of noise and vibration. Dang bearing in running in the has dust intrusion Shi on will produced dirt real noise. this noise is cyclical of, also also accompanied by vibration, its sound size does not fixed, Shi sometimes no.
　　Third inherent noise: roll road sound and various bearing and scroll friction sound is rolling bearing inherent of sound, roll road sound is by scroll body and roll road contact Shi of elastic characteristics produced of, dang deep ditch ball bearing rotating Shi, scroll body in roll road Shang scroll and issued of a continuous and sleek of sound; does not normal of scroll friction sound can issued "creak, and creak" like does not comfortable of metal friction exception sound, lubrication good Shi does not issued such of sound. so in general situation Xia not problem, only noise increases zhihou only needed attention.
　　About SKF bearing damage such as: roller bearing rings, ribs cards hurt, may consider as reasons, lack of lubricant, inappropriate, for oil discharge structure of defects, the intrusion of foreign bodies, misalignment, shaft deflection of deep groove ball bearings are too large, will also have these reasons coincide.
　　Therefore, only investigation SKF bearing damage, it is difficult to know the real causes of injury. However, if you know the conditions of used machinery, used for bearings, deep groove ball bearings around the structure, understand the situation before and after the accident, combined with the bearing damage and several reasons why visits, you can prevent the recurrence of similar accidents.
