摘　　要：圆锥滚子轴承的修型技术是使用带凸度的滚子以避免或降低滚动体和内外圈接触引起的边界应力集中。采用ANSYS软件对圆锥滚子不同凸度下的应力情况进行分析。分析结果表明,在一定的条件下带凸度的圆锥滚子轴承可以最大限度的降低滚动体和内外圈接触引起的边界应力集中。Modification techniques of the tapered roller bearings used the convex rollers can avoid or reduce the border contact stress concentration occurred between rollers and inner, outer ring raceways. Analysis is carried in the stress condition of different tapered rollers convexity with the ANSYS.The results show that the border contact stress concentration occurred between rollers and inner, outer ring raceways of tapered roller bearings with the convexity can be reduced maximumly under certain conditions.
