How to detect FAG one-way bearing vibration increase service life

Of vibration testing cycle is too long, start degradation information may not capture the one-way bearing, cycle set too short, and child and cost increases the detection work. So according to the structure characteristics of bearing and transmission way, speed, power and fault mode, reasonable selected vibration testing cycle. When FAG bearings in phase and stable operation, testing cycle can be longer; When there is defect and bearing failure, should shorten the testing period. When determining bearing testing cycle, shall abide by the following principles; A new bearing installation or mass after repair of one-way bearing early operation, shorter cycle ( If tests once a day) , after being bearing into stable operation, testing period may be extended appropriately. B test cycle should be fixed as far as possible. C to tally full-time bearing test stand, most FAG bearing test cycle can generally be classified as 7 to 14 days; For close to or higher than 3000 RPM high speed bearing, should at least test 1 times a week. D of workshop level bearing test, the test cycle can generally be classified as 1 times a day or once per class. E the measured vibration value is close to or more than the standard bearing alarm, to shorten the testing period. If the measured vibration value close to or more than the bearing down, shall promptly arrange maintenance downtime. If does not stop for production reasons, to strengthen the detection, testing cycle can be shortened to 1 day or less. To make FAG bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. Inspect, clean one-way bearings will be removed, with photography method such as first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, bearing cleaning divided into rough washing and fine washing, 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 bearing, 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. After cleaning, immediately on the FAG bearing coating anticorrosive oil or antirust grease. 2, examination and judgment to judge removed a one-way bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc. About the test results that can be used by bearing the judgement or master of bearing. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, FAG bearings shall not be used again, must be replaced. 1) One-way bearing fracture and defect of the parts. 2) The raceway surface material on the surface of the rolling strip.
