提出一种基于螺旋线映射的斜齿轮法面齿廓曲线求解新算法,消除了传统当量齿轮替代算法的原理性误差;提供了程序的开发实例。采用该算法生成的渐开线齿廓在齿轮量规和齿轮刀具的设计上得到应用。 A new algorithm based on helix mapping for helical gear profile curve is proposed, which eliminates the principle error of traditional equivalent gear replacement algorithm and provides an example of program development. The involute tooth profile generated by this algorithm is used in the design of gear gauge and gear cutter.
