| Abstract: | The author of this article has systematically made researches on various factors wich affect the bending fatigue stress on the tooth root of the driving gear in the increasing speed gearing in a helicopter,and derived the formulas for calculating the bdeding fatigue stress on the tooth root of the driving gear in the increasing speed gearing which is subjected to the actual loads including the sliding friction between teeth.It has been proved by researches that the effect of the sliding friction between teeth on the bending fatigue strength of the tooth root of the driving gear in the increasing speed gearing should not be neglected. |

| Keywords: | the increasing speed gearing in a Helicopter the sliding friction between teeth the bending fatigue stress |
