Jixie chuandong, 1991 文中研制成展成直齿及斜齿锥齿轮传动的计算机模拟软件。计算机模拟和切齿试验表明,现在广泛采用的切齿调整计算法,得到的齿面接触区很差:接触迹线几乎与分度锥母线平行,由齿的一端啮入,另一端啮出,大部分时间由齿的两端传动;在滚动检验机上略加载,扩展后的接触区是沿齿长方向的一条狭长的接触带,齿的上半部和下半部大部分不能参加啮合。调整滚比或横向移动刨刀,只能沿齿高方向或沿齿长方向移动这条接触带的位置,改变不了其形状和宽度。引入轮位修正之后,接触迹线的走向沿着齿高方向,而且还可以控制接触区的长度,得到比较理想的接触区。

Jixie chuandong, 1992 采用有限元混合法推导了求解复杂空间啮合轮齿应力场分析的有关公式,证明了在只有转动刚体位移的空间接触问题模型中刚体位移影响矩阵[Fu]和整体平衡矩阵[Q]互为转置;提出了多轮齿对同时接触时的计算方法,大大减少了分析计算量;建立了轮齿应力与齿面几何学及载荷之间的直接联系;最后将一对准双曲面齿轮副的计算结果与相关的实验结果进行了对比,两者是吻合的。本文的研究成果虽是针对螺旋锥齿轮而得到的,但它同样是分析其它复杂空间啮合齿轮副强度特性的非常有用的新方法。

Shiyou jixie, 2015 为了提高研磨性硬地层的破岩效率，设计了2种锥顶尺寸分别是5.5和.0 mm的新型锥形PDC齿。这种锥形PDC齿采用“犁削”破岩方式，比常规PDC复合片“切削”破岩方式更具攻击性。为了验证这种锥形PDC齿破岩效率，采用锥形PDC齿和PDC复合片制造了3种类型、5种型号直径为100 mm的试验钻头，在室内完成了花岗岩和硬砂岩2种岩样在5种钻压（10、15、20、25和30 kN）、2种转速（49和101 r/min）情况下的破岩试验。试验结果表明 ...
