Jixie chuandong, 2015 研究了弧齿锥齿轮小轮机床加工参数反求的算法实现问题。推导了变性法加工的弧齿锥齿轮小轮齿面方程,建立了理论齿面向目标齿面逼近的最小二乘法优化模型,采用基于置信域策略的Levenberg-Larquardt迭代算法反求小轮的机床加工参数,并与广义逆矩阵法、截断奇异值分解法进行了比较。以小轮的某种修形齿面为例,3种算法识别的齿面与目标齿面的残余偏差平法和分别为1.472 3×10-3 mm2、8.296 9×10-4 mm2、1.499 3×10-5 mm2。结果表明,相对于前两种识别算法 ...

Jixie chuandong, 1999 利用齿轮共轭原理建立了设计延伸外摆线锥齿轮的数学模型，以 Ｋ Ｌ Ｉ Ｎ Ｇ Ｅ Ｌ Ｎ Ｂ Ｅ Ｒ Ｇ 齿制的齿轮为例编制了程序来求解齿廓外形；还分析了迭代计算小齿轮齿面不收敛的原因，并求解了不发生根切的齿高变位系数，从而为齿高变位系数的选取提供了更广的范围。
