摘要：

单件冷轧成形的圆锥滚子轴承套圈存在锥度大、翘曲严重的问题，为了提高圆锥滚子轴承外圈的冷轧成形精度，采用理论分析、有限元模拟与实验验证相结合的方法，研究冷轧外圈成形工艺中的毛坯设计与优化方法，设计合理的冷轧毛坯。研究揭示了圆锥外圈单件冷轧过程中的套圈塑性变形与几何形状的演化规律，验证了毛坯设计的合理性与可行性，指出毛坯横截面积沿轴向的分布对套圈冷轧成形精度有着重要影响。同时，分析了轧制过程中作用于芯轴的轴向力的变化情况，指出轧制初期芯轴承受的轴向力较小，随着变形量增加，承受的轧制力增加，在轧制后期承受的轴向力达到最大。

For the problems of exceeding taper angel and serious warping degree existing in the single cold rolled outer ring of conical roller bearing, in order to improve its rolling accuracy, the methods of blank design and optimization in cold rolling process of outer ring were studied by the integrated application of theoretical analysis, finite element simulation and experiment verification, and the reasonable blank of cold rolling was designed. The evolution of plastic deformation and geometrical shape during the cold rolling process of single conical roller bearing outer ring was investigated to verify the reasonability and feasibility of the blank design. The results show that the horizontal crosssectional area distribution of blank along the axial direction has an important influence on the cold rolling precise of outer ring. Meanwhile, the axial force acting on the shaft during the rolling process was analyzed. The result presents that the axial force is lower at the initial stage of rolling process, and the axial force increases with the increasing of plastic deformation degree and reaches the maximum value at the final stage of rolling process.
