Abstract

The finite element model of NJP3226X1 cylindrical roller bearings was established by ABAQUS software, and the contact stress distribution of three kinds of modification curve(linear, circular-arc, logarithmic) were compared. The results showed that the maximal contact stress of logarithmic modified roller is the minimum, its stress distribute uniformly, and obvious stress concentration phenomenon does not exist, next is circular-arc modified roller, which stress at the two ends is too small and the stress in the middle is large, linear roller has the highest contact stress, and there is an obvious stresses concentration phenomenon at both ends. Through the analysis of the contact stress distribution of the logarithmic shaped roller under different repair quantities, the reasonable repair quantities are obtained.
