摘　　要：目前对最优圆锥滚子球基面半径的探讨,以固定内圈挡边倾角为前提,忽视了接触点位置的限制。正确的做法应是以固定接触点位置为前提,圆锥滚子球基面半径与挡边倾角相匹配情况下进行分析。基于此,以圆锥滚子轴承30310X2B为例,分别设置前提条件接触位置在1/3和1/2时,滚子球基面半径R取0.95ρ和0.85ρ,并计算出匹配的挡边倾角值。以ANSYS workbench对四种情况进行应力分析,探讨了不同接触位置下不同球基面半径的接触情况。At present,the discussion on the optimum radius of tapered roller sphere base surface is based on fixing the inclination angle of inner ring flange,ignoring the restriction of contact point position.The correct analysis method should be based on the fixed contact point position and the matching of the spherical base surface radius of tapered roller with the inclination angle of the retaining edge.Based on this,taking tapered roller bearing 30310X2B as an example,when the precondition contact positions are set at 1/3 and 1/2 respectively,the radius R of the roller spherical base surface is 0.95ρand 0.85ρ,and the matching retaining edge inclination angle is calculated.ANSYS workbench is used to analyze the stress in four cases.The contact conditions of different spherical base radius at different contact positions are discussed.
