摘　　要：本文着重论述继双曲面导辊副和圆锥导辊副开发出的第三代导辊副即圆柱圆锥导辊副的运动设计、几何设计和调整精度的计算与控制；通过理论分析和生产实践证明，采用合理的超精研工艺规范，用第三代导辊副定位支承并输送被超精研出的直圆柱，所得外径表面的几何精度 (包括宏观与微观 )和物理机械性能均比用第二代导辊副 (圆锥导辊副 )超精研出的还要高，成效更为显著。In this paper the motion design,the geometry design,the calculation and the control of regulation accuracy for the third era guide rollerpair,namely,cylinder－ tapered guide rollerpair developed following the hyperboloid guide rollerpair and the tapered guide rollerpair are discussed emphatically.Through the theoritical analyses and the production practice it is proved that adopting the rational superfinishing technology criterion,appllying the third era guide roller pair to locate,bear and transfer the geometry accuracy(containing the macroscopic and the microcosmic)and the physics－ mechanics performances of the gained outer diameter surface all are higher than the superfinishing out by the second era guide roller pair (the tapered guilde rollerpair).The effects are more remarkable.
