摘　　要：通过数字和理论分析，提出了零级直圆柱体贯穿式无心超精研圆锥导辊副的运动分析和设计方法。工艺试验和生产实践均证明，采用合理的超精研工艺规范，用圆锥导辊副定位支承并输送被超精研直圆柱体，超精研出的直圆柱面几何精度和表面层物理机械性能，均高于双曲面导辊副超精研，成效显著。附图7幅。Through mathematical and theoretical analysis, motion analysis and design method of tapered guide roller pair for through - feed centerless superfinishing for zero grade straight cylinders are proposed. Technological test and productive practice showed that if adopting reasonable superfinishing technological norm and using tapered guide roller pair to position, support and convey straight cylinders to be superfinished, the surface geometrical accuracy and surface layer physical and mechanical properties of superfinished straight cylinders are higher than that with hyperboloidal guide roller pair for superfinishing and ed results are obtained.
