【摘要】：圆锥滚子的无心贯穿式超精研过程中存在滚子与导辊之间的滑动现象,会影响加工质量,造成导辊磨损。分析导辊与滚子之间的周向滑动,建立了两者之间几何滑动模型并进行因素影响分析,得到纯滚动点最优位置方程。结果表明:纯滚动点在最优位置时几何滑动最小;导辊转速和半径越大,几何滑动越大,在不影响加工效率的情况下,应选择较小的导辊转速进行导辊设计和滚子加工;滚子锥角越大几何滑动越大,应加强对大锥角圆锥滚子超精滑动的控制。
[Abstract]:There is a slip between roller and guide roller in the centerless superfinishing process of cone roller, which will affect the processing quality and cause the wear of guide roller. The circumferential slip between guide roller and roller is analyzed. The geometric sliding model between them is established and the influence of factors is analyzed, and the optimal position equation of pure rolling point is obtained. The results show that the geometric sliding of pure rolling point is the smallest at the optimal position, and the larger the speed and radius of guide roller, the larger the geometric slip. Under the condition that the machining efficiency is not affected, the design of guide roller and roller machining should be carried out by selecting smaller guide roller speed, and the bigger the cone angle of roller is, the bigger the geometric sliding is, the better the control of super fine sliding of cone roller with large cone angle should be strengthened.
