摘要/Abstract

摘要： 针对实际生产中圆柱齿轮的高速齿廓倒棱需求，提出了连续切削的滚切倒棱新方法，完成了滚切倒棱刀具廓形设计。首先参考圆柱齿轮滚齿加工运动，建立刀具与齿轮的初始位置关系及刀具安装位姿坐标系，并通过倒棱参数与所建的安装位姿坐标系计算刀具安装位姿参数；其次根据倒棱运动及刀具安装位姿，建立空间运动坐标系并推导坐标系间的变换关系，通过连续求解刀具前刀面与齿轮倒棱目标廓形的接触点，提出刀具廓形计算方法；最后选取某型号的圆柱斜齿轮为倒棱对象，利用切削仿真软件完成齿轮及滚切倒棱刀具的三维建模，通过编写仿真运动程序实现倒棱切削仿真，在此基础上利用倒棱机床进行加工实验。仿真及实验结果表明，所设计的倒棱刀具能够满足圆柱齿轮的高效齿廓倒棱需求，也验证了刀具廓形计算方法的正确性。

Abstract: Aiming at the high-speed tooth profile chamfering requirements of cylindrical gears in actual productions, a new method of continuous cutting hobbing motion chamfering was proposed, and the profile design of the hobbing motion chamfering tools was completed. First, referring to the hobbing motion of cylindrical gears, the initial position relationship between the tool and the gear and the tool installation pose coordinate system were established, and the tool installation pose parameters were calculated through the chamfering parameters and the established installation pose coordinate system. Secondly, according to the chamfering motion and tool installation pose, a spatial motion coordinate system and derive the transformation relationship between the coordinate systems, and a tool profile calculation method was established by continuously solving the contact point between the tool rake face and the gear chamfering target profiles. Finally, a certain type of cylindrical helical gear was selected as the chamfering object. The three-dimensional modeling of the gears and the hobbing motion chamfering tools was completed by the cutting simulation software, and the chamfering cutting simulation was realized by writing the simulation motion program, the processing experiments were performed by chamfering machine. The simulation and experimental results show that the designed chamfering tool may meet the requirements of efficient tooth profile chamfering of cylindrical gears, and the correctness of the tool profile calculation method is also verifies.

Key words: cylindrical gear, tooth profile chamfering, tool profile, cutting simulation
