摘要： 在分析多种类似弧齿圆柱齿轮的几何形状参数与加工方法后，提出理想的弧齿圆柱齿轮的几何形状参数，分析弧齿齿轮副齿面的啮合特征，并通过对齿面方程和啮合线方程的图形化直观地表达两齿面的啮合状态，得到弧齿圆柱齿轮理想几何参数是：弧齿圆柱齿轮凸齿面与凹齿面弧线半径必须相等，在轮齿的不同径向截面上分度圆处的周向齿厚相等、周向槽宽相等、压力角相等.在此基础上，提出渐开线弧齿圆柱齿轮的加工方法与平行连杆式加工装置.

Abstract: This paper put forward ideal geometry parameters of arch cylindrical gear based on analyzing the geometry parameters and process methods of similar arch cylindrical gears. It analyzed the mesh characteristics of two tooth surfaces of gear pair. By graphical representation of the toothsurface equation and the mesh line expression，it demonstrated the mesh state of two teeth surfaces with graph, which can verify the feasibility of the gear’s geometry parameters. It can be concluded that the radius of concave surface and convex surface of the tooth must be equal in the gear, the tooth thickness is equal to the slot width on the different radial section of the gear teeth and the pressure angle at the reference circle must be equal. Based on it, the processing method of the involute arch cylindrical gear and the parallel rod gear processing device, were put forward.
