The impact of imports bearing life may be many factors that may result from factors and internal friction sound has been further instructions, use. The main factors used to adjust the installation, use and maintenance, maintenance and meet the technical requirements. According to imports bearing installation, use, maintenance, maintenance of technical requirements for the operation TIMKEN bearing contact load, speed, lubrication condition monitoring and inspection, found that the abnormal direct cause of the adjustment back to normal.
Installation conditions, one of the factors for bearing is often caused by incorrect installation package state changes between the various parts of the loading capacity, TIMKEN the bearing operating temperature the abnormal state of the primary factors, vibration, noise, progressive, raw material quality improved. The proportion of raw material quality factor in the analysis of bearing failure has decreased significantly, but it is still one of the main factors bearing failure.
1, strictly wire raw material inspection to prevent containing martensite, decarburization, surface roughness, surface stripes and raw materials to enter the drawing processing defects such as cleft; or pretreated, materials with improved performance after processing.
2, prevent and improve workpiece bad microstructure defects, such as coarse lamellar pearlite, mesh ferrite body.
3, Strictly control the quality of bearing steel wire metallurgy, to prevent contains non-metallic inclusions, folding defects blank into the machining process, to avoid the wire parts to brittle fracture failure.
4, Raw materials inspection found that the segregation of the wire, the preliminary heat treatment to eliminate defects and improve the organization, such as normalizing treatment under protective atmosphere, reduce segregation hazards.
