相邻两轮齿同侧齿廓间的齿距t与圆周率π的比值(m＝t/π)﹐以毫米为单位。模数是模数制轮齿的一个最基本参数。模数越大﹐轮齿越高也越厚﹐如果齿轮的齿数一定﹐则轮的径向尺寸也越大。模数系列标準是根据设计﹑製造和检验等要求制订的。对於具有非直齿的齿轮﹐模数有法向模数mn﹑端面模数ms与轴向模数mx的区别﹐它们都是以各自的齿距(法向齿距﹑端面齿距与轴向齿距)与圆周率的比值﹐也都以毫米为单位。对於锥齿轮﹐模数有大端模数me﹑平均模数mm和小端模数m1之分。对於刀具﹐则有相应的刀具模数mo等。标準模数的应用很广。在公制的齿轮传动﹑蜗杆传动﹑同步齿形带传动和棘轮﹑齿轮联轴器﹑花键等零件中﹐标準模数都是一项最基本的参数。它对上述零件的设计﹑製造﹑维修等都起著基本参数的作用(见圆柱齿轮传动﹑蜗杆传动等)。
