Koyo deep groove ball bearing vibration fault diagnosis of operation maintenance method

Koyo bearing temperature slowly rising operation, usually. 1 - 2 hours, in order to reach a steady state. The normal temperature of deep groove ball bearings due to mechanical, thermal, speed and load of the heat capacity of each are not identical. If the lubrication, the appropriate equipment, the temperature of the bearing can be rapid rise, there will be unusually high temperature, when necessary to stop operation, take the necessary preventive measures. Based on lots of testing data, lists the various mechanical work, in the average temperature of the bearing outer ring, for your reference. Through the lubrication, due to the temperature, speed, load, environment, the numerical approximation of the temperature range in the table. Koyo bearings will be removed when check, use first method such as photography appearance record. In addition, imported bearing to confirm the amount of residual lubricant and lubricant sampling, and then wash the deep groove ball bearings. A, bearing cleaning divided into rough washing and fine washing, bearing can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil deep groove ball bearings, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. In order to judge removed koyo bearing can be reused, Germany bearing to inspect the dimension precision, rotating accuracy, internal clearance as well as the matching surface, raceway surface, cage and seal rings etc. Bearing vibration in the operation to identify the inspection, bearing vibration of deep groove ball bearing is very sensitive to damage such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement. Through the use of special bearing vibration zhangs gauge ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values for koyo bearing conditions of use or sensor installation position and different, so you need to analyze the measurement value of each machine in advance after comparison judgment standard. Koyo bearings of the main causes of vibration fault of friction and mechanical two aspects. Sometimes a single friction problem, and sometimes a single mechanical problems, sometimes are two factors work together. Single friction or mechanical causes vibration is easy to determine, two factors work together to produce vibration problem is difficult to analysis. Vibration is relatively easy to distinguish between the friction and mechanical factors, in deep groove ball bearing a halt moment, disappear immediately, if the vibration is friction problems; If vibration slowly disappeared, it is caused by mechanical factors. If is two factors work together, you can observe what power instantaneous fault disappeared, what reason is still at work.
