中文摘要：

为解决锥形摆线啮合副软齿面的切削加工和硬齿面的磨削加工，提出用指锥刀具／磨具直接形成零件轴向锥形，而零件断面摆线或圆弧齿通过展成方式形成的“指锥包络”切削／磨削加工方法。以锥形摆线轮的大端作为基准，推导锥形摆线轮和锥形圆弧内齿轮切削／磨削过程中的刀具／磨具中心轨迹方程。针对理论推导的刀具／磨具中心轨迹方程，运用Pro／Engineer软件，对啮合副零件的切削／磨削加工过程进行了运动仿真，验证理论推导的正确性和加工方法的可行性。在理论推导及加工仿真的基础上，进一步完成样机的试制。在ZC1066H三坐标测量机上，对样机的锥形啮合副零件进行加工精度测量，测得锥形摆线轮断面周节累积误差为0．035mm，圆弧内齿轮断面周节累积误差为0．014mm，测量结果表明该加工方法切实可行，且具有较高的精度。

英文摘要：

For solving the cutting problem of gear flank and the grinding of the hardened profile of the conic cycloidal meshing elements, a new cutting/grinding method called ＂finger cone enveloping＂ is put forward, that is, the axis direction cone of the gear is shaped by finger conic curer or grinder, and cycloid or arc profile is formed by enveloping. Setting the bigger end of conic cycloidal gear as datum plane, the cutter/grinder center paths are developed. Cutting and grinding processes are simulated with Pro/Engineer software, which verify the correctness of theory deduction and feasibility of machining. On the basis of theory deduction and machining simulation, prototypes of the gears are produced. The machining precision of the conic meshing parts for prototypes of the gears is measured with three-dimension measuring machine of ZC1066H, and conic cycloidal gear accumulative pitch error is 0.035 mm and conic-arc-inner gear is 0.014 mm. Gear error measuring results demonstrate that the method of ＂finger cone enveloping＂ not only is feasible but also has fairly high precision.
