齿轮传动由于其结构紧凑,传动效率高,工作可靠,承载能力大等优点而获得广泛应用。随着齿轮传动向高速、重载方向的发展,在齿轮设计计算中,强度计算仍是核心问题。因而齿轮传动强度计算的理论和方法,仍是目前各国有关研究部门进行探求的内容非常广泛的课题。我们知道,齿轮的失效形式是确定其设计准则的客观依据。因此,现今齿轮传动的 Gear drive due to its compact structure, transmission efficiency, reliable, large carrying capacity and other advantages and has been widely used. With the gear transmission to high-speed, heavy-load direction of development, in the gear design calculation, the strength calculation is still the core issue. Therefore, the theory and method of calculating the strength of gear transmission are still a very wide range of subjects that are currently being explored by relevant research departments in various countries. We know that the failure of gear form is an objective basis to determine its design criteria. So now gear drive
