一、前言渐开线齿轮公法测量跨越齿数计算公式有许多种形式,最早的要算马格公司的近似公式了。后人不断对跨齿数公式进行改进,逐步地提高了公式的合理程度,但仍然还没有达到精确阶段。以至于:仅就为工程界所采用的也不下三、四种形式。其中笔者认为
I. INTRODUCTION There are many kinds of formulas for measuring the number of teeth crossed by involute gears in public law. The earliest formulas to approximate the number of teeth are the approximate formula of the company. Future generations continue to improve the cross-tooth number formula, and gradually improve the reasonableness of the formula, but still not reached the precise stage. As a result: only for the engineering industry nor the use of the next three or four forms. Which I think
