| 摘 要： | 圆锥滚子轴承的套圈是重要的承栽部件，对轴承的性能有着重要的影响。成对冷辗扩生产不仅能抵消因不对称变形产生的轴向力、提高制件精度、延长芯辊寿命，还能提高生产效率。通过对成对冷辗扩过程中圆锥套圈变形过程分析与受力分析，推导出圆锥套圈成对冷辗扩成型时咬入条件、锻透条件、冷辗扩力的计算方法，毛坯设计方法及模具设计方法，并对圆锥轴承329／32（ISO355系列2BD）圆锥套圈成对冷辗扩进行试验验证，

| Abstract: | Taper roller bearing race, a very important load-bearing component, has significant affection on the property of the bearing. Twinning cold ring rolling can not only counterbalance axial force of asymmetry deformation, increase accuracy and prolong life of idle roller, but also be more productive. Through the deformation process analysis and loading analysis, the bite condition, plastic penetration condition, calculation method of rolling force, stock design method and tolling design method of twinning cold ring rolling were deduced. The taper race of bear 329/32(2BD of ISO355 serials) was twinning cold rolled for experiment confirmation. |
