| Abstract: | Hybrid ceramic ball bearing is one of the main bearings which are used to support the high-speed motorized spindle,the operation condition of which may affect the reliability of the motorized spindle directly.Therefore,it is necessary to choose the appropriate hybrid ceramic ball bearing.This paper elaborates the basis of the hybrid ceramic ball bearing’s selection,including how to choose the type and size,and the validation for limit speed,mainly derives the estimation formula of ceramic ball and outer ring’s lifetime of hybrid ceramic ball bearing,and the formula of its lifetime correction coefficient under different reliability requirements.And then get the basic rated dynamic load of ceramic ball and outer ring,put forward the requirements which the selected ceramic ball bearing should accord with. |
