高速电主轴轴承接触特性仿真研究
Research on Simulation of Contact Characteristics of High Speed Electric Spindle Bearings
摘要
Abstract
Bearings are the core rotating components of high-speed electric spindles.Accurately analyzing and predicting the contact characteristics and lifespan of high-speed electric spindle bearings is the key to ensuring the reliable and stable operation of high-speed electric spindles.To this end,the contact characteristics of high-speed electric spindle angular contact ball bearings are studied and simulated.Considering the high-speed and ultra high speed operating conditions of the electric spindle,a three-dimensional geometric model,mechanical model,force model and finite element analysis model of high-speed electric spindle angular contact ball bearings are established.A static simulation analysis is conducted on the equivalent stress,contact stress,and radial deformation of angular contact ball bearings under load and constraints.The results show that the overall deformation of the contact area between the inner ring and the rolling element is relatively small.The contact stress of the inner ring of the bearing is greater than that of the outer ring,and the overall lifespan of the outer ring is higher than that of the inner ring.The lifespan of the non-contact area between the rolling element and the inner and outer rings is higher than that of its contact area,which can meet practical usage requirements,and obtaining the contact characteristics of angular contact ball bearings has important theoretical significance and engineering application value for further research on extending the fatigue life of angular contact ball bearings.关键词
