摘要：The geometric error of bearing elements mainly includes diameter size error of rollers and geometric form er-ror of ring raceway which is described in Fourier series.The contact between roller and raceway is treated as nonlinear springs,and the mechanical model is built.The contact load of each roller is solved by using Newton-Raphson algo-rithm.The analysis results show that the variation of load distribution is related to form and error value of raceway when the error of raceway is existed;the variation rate of maximum contact load of roller is about 481.6 N/μm when the error of single roller is existed;the number of loaded rollers will change when the error of many rollers is existed,if the roller are reduced from the middle to the both sides,the number of loaded rollers is reduced and vice versa.
