How to eliminate needle roller bearing fault

Jiaxing bearing manufacturing co. , LTD. , eliminate needle roller bearing fault methods: one, the vibration diagnosis technology needle bearing element surface fatigue spalling, indentation, or the local corrosion, needle roller bearing will appear in the operation of the periodic pulse signal. The periodic signal can be installed on the bearing seat of sensors ( Type speed or acceleration) To receive, and through the analysis of the vibration signal to diagnose the faults of needle bearing. Features: vibration diagnosis technology widely used; Can realize on-line monitoring; Diagnosis, diagnosis theory has been mature. Application: apply is especially suitable for needle roller bearing fault in rotating machinery monitoring. Second, the needle roller bearing wear particle iron spectrum diagnosis technology and its working conditions are closely linked. With wear particles in lubricating oil by a strong magnetic field, under the action of strong magnetic field, grinding grain on precipitation in iron spectrum according to certain rules, can be made on the ferrographic microscope ferrographic pieces in qualitative observation and quantitative instrument testing, on the basis of judging the working condition of needle bearing. Characteristic: the machine without disintegration; Low investment and good effect; Needle roller bearing can be discovered early fatigue failure; Can do wear mechanism research. Application range: applicable to oil lubrication of the needle roller bearing fault diagnosis, with grease lubrication needle roller bearing is more difficult. Three, good lubrication performance of the oil film resistor diagnostic technique of needle roller bearing, due to the effect of oil film, there is a lot of resistance between inner and outer ring. Therefore, by measuring the resistance of the needle roller bearing inner and outer ring, can judge the needle roller bearing exception. Features: can use the same criteria for different working conditions. The surface spalling, indentation and crack the diagnosis of abnormal effect is poor. Application range: applicable to the axis of rotation exposed. Sources: the list /? 3 _1. 超文本标记语言
