Comparative Analysis of Transmission Error between Straight Bevel Gear and Zero Bevel Gear

锥齿轮是航空传动系统中必不可少的部件,直齿锥齿轮和零度弧齿锥齿轮由于传动的相似性,在诸多应用中可以互换,但由于齿形的不同,其传动性能仍存在较大差异。本文分别构建直齿和零度弧齿锥齿轮的精确几何模型,并基于有限元进行准静态接触分析,对比分析2种类型齿轮传递误差的差异,并采用不同的载荷以及安装误差工况,分析直齿和零度弧齿锥齿轮传递误差的变化规律,为这2种不同类型齿轮在航空领域中的选择和应用上提供参考。

Bevel gear is necessary for aeronautical transmission system, As the similarity of transmission, straight bevel gear and zero bevel gear are changeable in many applications. But their transmission performances are different because of their different tooth profile. In this article, the accurate geometric model of straight bevel gear and zero bevel gear were established, and static contact analysis of these gears were carried out by the finite element method, according to which the difference transmission error of the two type gears were analyzed. Under the different working conditions, the change rules of the two type gear＇ s difference transmission were obtained. It can be reference for two type gears on the selection and application in aviation.
