新型非对称齿轮滚刀设计理论与方法

Theory and method of hob design for a new-style asymmetric gear

从齿轮啮合和滚刀设计的基本原理出发,提出了非对称渐开线圆柱齿轮滚刀的设计方法,推导了相应的计算公式,给出了计算实例,实现了非对称齿轮滚刀的参数化实体模型.根据齿轮加工原理,分别用面向对象的Visual Basic和Autolisp语言对非对称齿轮范成加工进行参数化编程,模拟仿真了非对称齿轮加工的包络过程.

Based on the principle of gear mesh and hob designing, a method to design an asymmetric involute spur gear was provided and the calculation formula was deducted. The parameter solid model was set up using a calculation example. On the base of the principle of gear manufacture, parametric programs programmed with Visual Basic software and Autolisp program were separately introduced to simulate the envelope process of asymmetric gear manufacture. The result shows this method provides a foundation for new-style asymmetric gear manufacture and experimental study .
