- bearing TIMKEN bearing anti-rust and maintenance knowledge

In order to prolong the service life of TIMKEN bearings, use process should pay attention to the bearing rust. Methods of rust of TIMKEN bearings are: 1) Surface cleaning: cleaning must be based on the nature of the TIMKEN bearing and the conditions at that time, select the appropriate method. There are usually used solvent cleaning, chemical cleaning and mechanical cleaning. 2) Surface available filter after dry clean dry compressed air blow dry, or in 120 ~ 170 ℃ dryer for drying, dry clean gauze TIMKEN bearing is also available. The method of coating anticorrosive oil: 1) Soak method: TIMKEN bearing by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil. The temperature of the oil film thickness can be controlled by anti-rust oil or viscosity to achieve. 2) Brush method: used for soaking or spraying TIMKEN bearing or not apply special shapes of TIMKEN bearings, brush should not only pay attention do not produce rust-proof oil accumulation, also should pay attention to prevent leakage. 3) Spray method: some large TIMKEN bearing cannot be oiled by soaking method, generally about 0. 7 mpa pressure filtering compressed air spraying where clean air. Spray method used solvent XiShiXing rust-proof oil or thin layer of anti-rust oil, but must use perfect fire protection and labor protection measures. The influence of the purity of the bearing of TIMKEN bearing life is quite large, the company has the specialized test, the result is the difference for several times or even dozens of times. The higher the purity of the TIMKEN bearing, the longer the life and others test showed that different cleanliness of lubricating oil had a great influence on the ball bearing life. So, to improve the purity of the lubricating oil can prolong bearing's life, in addition, if the lubricating oil containing dirt particles control under 10 um, bearing life is growing into 7 times. ( 1) Influence on vibration test center test results show that: cleanliness seriously affecting bearing vibration level, especially the vibration of the high frequency band. High cleanliness of low vibration velocity values, especially in high frequency band. ( 2) Dust from the noise impact on bearing grease for noise test, the influence of proof dust, the more the greater the noise. ( 3) Affect the performance of lubrication TIMKEN bearing cleanliness, not only affect the formation of lubricating film, still can cause the deterioration of the grease and accelerate its ageing, thus affecting the grease lubrication performance degradation.
