齿轮范成仪教学仪器的改进

Improvement of the Teaching Instrument of Gear Meshing Machine

齿轮范成仪具有演示渐开线齿廓的形成过程功能,操作简便快捷。通过实验,学生可以掌握渐开线产生根切和避免根切的方法以及刀具变位对齿形的变化及对齿轮各参数的影响。

The gear meshing machine has function of demonstrating the forming process of involute tooth profile,which is easy to operate.By experiment,students can master the ways of involute’s generating root cutting and avoiding root cutting and the effect of cutting tool deflection to the gear’s change and gear’s parameters.
