一问题的提出 用测量齿轮公法线长度来控制齿轮的齿厚是一种简单易行的方法。无论内、外齿轮或斜齿轮,都可以藉助于一把普通的卡尺(或公法线百分尺)准确地控制齿轮的齿厚。为了便于测量,要求量具的卡脚应接触于轮齿的中部。接触点的位置取决于测量时的跨测齿数(对内齿轮是齿沟 One of the problems raised is that it is a simple and easy way to control the gear tooth thickness by measuring the normal length of the gear. Both internal and external gears or helical gears can be used to accurately control gear tooth thicknesses with the aid of an ordinary caliper (or common-law scale). In order to facilitate the measurement, the caliper of the measuring tool should be in contact with the middle of the gear teeth. The position of the contact point depends on the number of spans measured during the measurement (on the internal gear is the groove
