一、引言計算齒輪强度的公式,形式繁多,不下數十餘种。各國的工廠在設計齒輪時,往往引用本廠自己的賽料。在这些资料中,公式常常是經验的,其物理意义不太明確,而由实驗得來的各項修正係數倒起着主要的作用。在一定的條件下,熟練地運用这些資料,也可以得到令人滿意的结果:但是从幫助设计者理解与掌握齒輪强度計算的意义与实質、启示並指導設計者來改進齒輪的設計这一观點看來,是不够令人满意的。為此,筆者不揣淺陋,收集了 I. INTRODUCTION The formula for calculating the strength of gears has many forms and no less than several dozen kinds. Countries in the design of gear factory, often quoted our own factory material. Of these materials, the formulas are often empirical and their physical meaning is less clear, and the experimental correction factors play a major role. Under certain conditions, skilled use of these data can also be satisfactory results: but to help designers understand and grasp the meaning and essence of gear strength calculation, enlighten and guide designers to improve the gear design From the point of view, it is not satisfactory enough. To this end, I do not guess humble, collected
