【 HRB bearing knowledge 】 The classic bearing fault development and stage

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. A change, the process of bearing fault bearing fault development law is not according to the linear degradation, but changes according to the index law. Second, bearing fault development phase 1, the initial stage of low noise is normal; Low temperature is normal; To use ultrasonic vibration peak energy, acoustic emission measurement, a defect bearing outer ring; Low vibration amount is small, no discrete bearing failure frequency peak; Low residual life is more than 10%. 2, the second stage low noise slightly increased; Low temperature is normal; Ultrasonic, acoustic emission, vibration peak energy have large increase, a defect bearing outer ring; Low vibration amount increased slightly ( The total vibration acceleration and vibration velocity) ； Low spectrum of a logarithmic scale can clearly see the bearing fault frequency, linear scale spectrum. It's rare to see, on the horizontal noise increased significantly; Low residual life 5%. 3, the third stage low noise can be heard; Low temperature slightly higher; Very high ultrasonic, acoustic emission, vibration peak energy, bearing outer ring with reason; Low total vibration acceleration and vibration velocity has a big increase; Low on the spectrum of the linear calibration clear bearing failure frequency and its harmonics and sideband; Low vibration spectrum noise obviously improve the horizon; Low residual life is less than 1%. 4, the fourth stage of low noise intensity change; Low temperature increased significantly; Ultrasonic, acoustic emission, vibration peak energy increases rapidly, then gradually decreases, and the bearing outer ring is in fault state before damage; Low amount of vibration velocity and vibration displacement quantity increased obviously, the total vibration acceleration decreased; Low low vibration peak of the dominance of bearing failure frequency, vibration noise in the buccal spectrum horizon is very high; Low residual life less than 0. 2%.
