diametral pitch

径节

可使用单锋刀具配合具有齿轮轮廓形状的样板(Template)导引下制造齿轮.齿轮创制法所使用的刀具形状并不等於齿间隙的形状.它是利用相同的径节(Diametral pitch)的两渐开线齿轮,不论其齿数的多少皆可互相啮合的原理,

shaping

成形

3、在渐开线圆柱齿轮类型会话框中,选择普通齿轮(General Gear)、直齿轮(Straight Gear)、内齿轮(Internal Gear),在加工(machining)中选成形(shaping). 单击确定,显示渐开线圆柱齿轮参数会话框. 4、选择标准齿轮(Standard Gear)标签,

dedendum circle

圆

基圆(Basic Circle):绘制渐开线齿形时作为基础之圆. 齿根圆(Dedendum Circle):通过齿根之圆. 节距(Pitch):相邻两齿间相对应点的弧线距离. 法向节距(Normal Pitch):渐开线齿轮沿特定断面的同一垂线所测得的节距.
