IKO bearing friction vibration failure analysis

Friction is mainly refers to the abnormal vibration of rolling bearing vibration, in general friction vibration likely to occur in large ball bearing, especially with grease lubrication grease lubrication performance not good when are more likely to happen. The generation of rolling bearing friction vibration often have a direct bearing and lubricating oil properties. When the lubricant performance is bad or not clean, is prone to friction vibration, but also related to rolling bearing outer raceway machining quality, if the use of special precision machining method, can better control the friction vibration. Rolling bearing vibration is basically caused by the vibration of the bearing ring, and bearing structure, stiffness, manufacturing accuracy, installation and usage and other factors. If the roll rolling bearing inner ring road have larger radial ripple, which ring rotates the bearing outer ring to produce radial vibration. Waves of bearing inner ring will not only cause the radial vibration of outer ring, but also will cause the axial vibration of outer ring, bearing when the axial load can make the bearing inner and outer ring of the axial relative position changes, so the inner ring rotates the bearing outer ring, produce the axial vibration sieve mouth at work, for high-speed rotating bearing, caused by the vibration frequency of corrugated, likely to equal the vibrator shaft rotational frequency, which produce resonance. IKO bearings, the main task of the failure analysis is based on a lot of background material, analyze data and failure forms, find out the main factors of rolling bearing failure, so that the improvement measures are put forward, lengthen spherical roller bearing, avoid premature failure of the bearing of the sudden. IKO bearing vibration of rolling bearing failure effect is very significant. For example, peeling, indentation, rust, crack and wear will be reflected in the bearing vibration test so through the use of special bearing vibration measurement device ( Frequency analyzer and vibration meter, etc. ) Can measure the size of the vibration through the frequency distribution can be concluded that the details of the abnormal vibration measured values due to the use of spherical roller bearing premise or sensor installation position and different therefore require prior to each machine measurement value judgment dimension after analysis and comparison.
