Designing special tooling for machining interal gear on gear hobbing machine

在滚齿机上设计专用工装加工内齿轮

At present, traditional processes of hob are radial relief grinding in general, when we adopt this process, it will cause tooth flanks distortion, reduce hob proper tooth profile, and be lead to hob accuracy lower, which restricts gear hobbing level further seriously.

目前滚刀一般采用径向铲磨方式进行精加工，由于径向铲磨会造成齿侧面畸变，减小齿形合格长度，导致滚刀精度寿命低，径向铲磨工艺严重制约着滚齿加工水平的进一步提高。

To reduce the index error caused by gearing chain of the gear hobbing machine, a mathematical model for compensating error is established, a program for compensating error is designed, and an algorithm for compensation is chosen.

针对滚齿机传动链分度的误差，提出了误差补偿的数学模型；设计了滚齿机传动误差补偿方案；

The manual programming method of gear hobbing, which uses manpower to carry on processing procedure, computing, compiling programmings, inputing programmings, checking programmings and so on, usually leads to huge calculating work, high error rate and low efficiency.

齿轮加工采用手工编程需人工进行工艺处理、数值计算、编写程序、输入和校验程序等步骤，其计算量大，出错率高且编程效率低。

The paper, based on analyzing the errors in clamps for gear hobbing machine and gear slotting machine when positioning and tool-setting, proposes to use several important gearing tolerances to limit the errors in clamp when positioning and tool-setting.

重点分析常用的加工齿轮的滚齿机和插齿机夹具在机床上定位和对刀误差，并用常用的几个重要的齿轮公差来限定机床夹具的定位和对刀误差。

By establishing gear hobbing mathematic model, the forward some reference standard based on experiment.
