How to choose reasonable rolling sunthai bearing clearance? - bearing knowledge

by：Waxing 2020-06-08

Clearance is whether sunthai bearing can work normally one of the important factors. Choose appropriate sunthai bearing clearance, can make the rational distribution of load between the rolling element; To limit shaft ( Or shell) The axial and radial displacement to ensure the accuracy of the axis of rotation; Make sunthai bearing can work normally under the required temperature; Can reduce sunthai bearing vibration and noise at work, etc. , thus, sunthai bearing clearance of sunthai bearing life, temperature rise, vibration and noise has a great influence. When choosing sunthai bearing clearance, should be considered in addition to sunthai bearing working conditions ( Such as load, speed, temperature, etc. ) And the use of performance requirements of sunthai bearing ( Such as friction torque, vibration and noise, rotating accuracy, etc. ) Sunthai bearing and range of the shaft and the shell lead to clearance decreased; Sunthai bearing work, lead to difference between inner and outer ring clearance decreased; Shaft and the shell of the manufacturing material clearance decrease or increase caused by the different expansion coefficient. Use experience has shown that for sunthai ball bearing is the most suitable work clearance approximate to zero; For roller bearing sunthai optimum working condition should maintain a small amount of clearance. In the required supporting rigid good parts ( Such as spindle) , also can have certain numerical preloaded. 【 The bearing network]
