Deep groove ball bearing early failure reason

At present more mature detection system in practical application are the following. （ 1) Lateral bearing pulse vibration device bearing fatigue wear ( Or fatigue spalling) To produce vibration, the receiver will mechanical pulse signal is converted to electrical signals and amplification. When the pulse number is beyond the normal range reaches mutation, immediately report to the police, bearing stop using it. （ 2) Bearing temperature alarm device, surface wear or fatigue can make poor lubrication bearing surface heat, when the temperature of the heating to a certain limit, the alarm, and stop running bearing. （ 3) Periodically bearing in the operation of the state at the time, or monitor for defects is development trend. （ 4) Ferrographic diagnosis method of timing extraction work bearing grease samples, iron spectrometer is used to inspect the grinding grain number, size and shape characteristic, can find out the degree of fatigue and wear and tear, found signs of bearing failure. Prediction, prevention of premature failure of the bearing of the way the service life of bearing in the important mechanical equipment is an important indicator, to understand and master the working state of the bearing, prediction, prevention of premature failure of the bearing is necessary. Usually has the following main way. （ 1) The use of advanced technology, improve the bearing life and reliability. Including the reform of structure optimization design, processing technology, material selection and refined, high efficient degree of lubrication, fine assembly and installation, and so on. ( 2) Strengthen bearing products quality inspection and supervision, to ensure the quality of bearing products meet the requirements of relevant standards or design. （ 3) To strengthen the monitoring and diagnosis of bearing working condition, early detection is unusual, adopt preventive measures to prevent sudden accidents may cause great losses. 2. Fault diagnosis test system of modern bearing fault diagnosis technology, and precision of testing system and monitoring means together.
