INA bearings vibration analysis of causes to loss

INA bearings factors mainly refer to installation and adjustment, maintenance, maintenance, repairs and other compliance with technical requirements.
　　Loss of bearings for various reasons, all design and manufacturing process factors are associated with loss of INA bearings, bad judgment to analysis. But in normal circumstances, generally can be used from both factors and internal factors to consider and analyse.
Loss INA bearings using factors mainly refer to installation and adjustment, maintenance, maintenance, repairs and other compliance with technical requirements. Installation conditions is one of the leading factors in the use factor, bearings package is often caused by installing is not the right state of change between the various parts of the bearings, INA bearings under abnormal functioning and loss. Depending on the bearings of the installation, use, maintenance, maintenance technical requirements, the load borne by the bearings in operation, speed, temperature, vibration, noise monitoring and checks and lubrication conditions, abnormal findings immediately find the cause to adjust, bring it back to normal. In addition, analysis of the grease quality and atmosphere surrounding media, testing is also important.
　　According to INA bearings technical requirements for the installation, use, maintenance, maintenance, INA bearings in the operation to take the load, speed, temperature, vibration, noise monitoring and checks and lubrication conditions, abnormal findings immediately find the cause to adjust, bring it back to normal. Installation conditions is one of the leading factors in the use factor, bearings package is often caused by installing is not the right state of change between the various parts of the bearings, bearings an abnormal state operation and early ending life of internal factors mainly refer to structural design, manufacturing processes and materials quality factors determining the quality of bearings three.
　　1) bearings design parameters: include bearings rolling element number, ring wall thickness and clearance.
　　2) bearings parts manufacturing errors: including the raceways and rolling elements of surface roughness, crossing the line and the circle of difference. A large number of experimental studies have shown that, effect of waviness on bearings vibration dominate, and relatively little effect of surface roughness and roundness.
　　3) bearings operating conditions: bearings in operation process, load, speed, three for INA bearings lubrication conditions most vibration.
　　4) INA bearings installation parameters: bearings and shafts and housings matching bias, installation and other factors also have an impact on the vibration of the bearings.
