摘要： 双盘直槽（double-disc and linear-groove， DDLG）研磨方法是以1个平端面研磨盘和1个具有多条直沟槽的研磨盘为对磨研具，对圆柱滚子的滚动面进行精密加工的新方法。在加工过程中，圆柱滚子沿直沟槽连续供料，在2个研磨盘的摩擦力矩驱动下连续自转。研磨盘材料的选择是搭建双盘直槽研磨设备的基础。为了确定适用于双盘直槽研磨方法的研磨盘材料组合，基于摩擦磨损实验展开相关研究。首先，基于摩擦原理，分析了圆柱滚子的运动状态和研磨盘材料的摩擦特性对研磨效果的影响，并确定了研磨盘材料摩擦系数的筛选条件。然后，通过销-盘摩擦磨损实验测试了铸铁、45钢、黄铜、聚四氟乙烯（polytetrafluoroethylene， PTFE）、有机玻璃（polymethyl methacrylate， PMMA）、125%铸铁基固结磨料和125%树脂基固结磨料等多种备选材料在研磨条件下的摩擦系数、耐磨性和排屑性能。最后，搭建了双盘直槽研磨试验台，通过观察圆柱滚子的自转情况来验证基于摩擦磨损实验的研具选材方法的合理性。通过摩擦磨损实验测得，铸铁和45钢的滑动摩擦系数大，磨削效率高，但耐磨性差，适合用作大去除量场合的上研磨盘材料；有机玻璃的滑动摩擦系数大，耐磨性好，磨削效率高，适合用作小去除量场合的上研磨盘材料；聚四氟乙烯的滑动摩擦系数小，耐磨性好，可用作下研磨盘直沟槽材料；固结磨料的滑动摩擦系数变化大且易堵塞，不适合用作研磨盘材料。研究结果可为双盘直槽研磨设备的设计提供可行的研具选材依据。
Abstract: Double-disc and linear-groove (DDLG) lapping method is a new method of precision machining the rolling surface of cylinder roller by using a flat-end lapping disc and a lapping disc with several linear grooves as lapping tools. During the machining process, cylinder rollers are fed continuously along the linear groove and continuously rotate driven by the friction torque of two lapping discs. The selection of lapping disc material is the basis for the construction of double-disc and linear-groove lapping equipment. In order to determine the material combination of the lapping disc that is suitable for the double-disc and linear-groove lapping method, relevant researches are carried out based on the friction and wear experiment. Firstly, based on the friction principle, the influence of the movement state of the cylinder roller and the friction characteristics of the lapping disc material on the lapping effect was analyzed, and the screening conditions for the friction coefficient of the lapping disc material were determined. Secondly, the friction coefficient, wear resistance and chip removal performance of various materials, such as cast iron, 45 steel, brass, polytetrafluoroethylene (PTFE), polymethyl methacrylate (PMMA), 125% cast iron-based consolidated abrasive and 125% resin-based consolidated abrasive were tested by friction and wear experiments under lapping conditions. Finally, a double-disc and linear-groove lapping test bench was built to verify the rationality of the material selection method based on the friction and wear experiment by observing the rotation of the cylinder roller. The results of friction and wear experiments showed that the cast iron and 45 steel had large sliding friction coefficients and high lapping efficiency, but its wear resistance was poor, which were suitable for the upper lapping disc material for large removal occasions; plexiglass had a large sliding friction coefficient, good wear resistance and high lapping efficiency, which was suitable for the upper lapping disc material for small removal occasions; PTFE had a small sliding friction coefficient and good wear resistance, which was suitable for the straight groove material of lower lapping disc; the sliding friction coefficient of consolidated abrasive varied greatly and it was easy to block, so it was not suitable for the lapping disc material. The research results can provide a feasible material selection basis for the design of double-disc and linear-groove lapping equipment.
