Bearing these stages in the life cycle is very important to obtain maximum service life of the bearing. Through the implementation of correct maintenance and use of the right tools, you can significantly extend the life of the bearing, increase factory productivity and production efficiency.
Including temperature, noise, speed and vibration measuring instruments during the run, using basic condition monitoring tools detect bearing status on a regular basis is important, such as temperature, vibration, and noise measurement. Regular testing can identify potential failure, helping to prevent unexpected downtime. Therefore, you can schedule a maintenance plan in line with the production plan, improve productivity and production efficiency.
Fatigue failure was a failure of the bearing surface forms, mainly for fatigue crack initiation and extension and fracture process, under the alternating load failures arising from the long-term effects of metals. Cracks in two ways:
1: from surface Shang see, this is, bearing in scroll contact process in the, due to in work surface of plastic deformation and strain hardened surface of contact stress cyclical changes by caused of external load of role, and finally in small crack from development of within surface, in both Zhijian of surface crack of formed, due to work surface of lobby doors wedged into lubricant, open of forces, severe combat in wall Shang, forced crack forward advance;
2: from the surface, again under pressure, surface contact, initially in exposed places on the surface of certain depth of cracks on cracking, surface direction and point of view, to a certain depth, from behind the surface of the contact surface, and beyond the surface, corrosion and eventually split, leaving a Ma Hang.
