弧形齿联轴器承载能力的有限元分析

Finite element analysis of the loading capacity of curved-tooth gear coupling

以弧形齿联轴器的齿轮副为研究对象,基于弧形齿的加工原理,对齿轮副内外啮合齿轮建立三维模型,再将模型导入有限元软件中,分析内外齿轮在不同轴间倾角下的应力分布,并对齿轮进行强度校核,最终得出弧形齿联轴器的承载能力与内外齿轮轴间倾角的关系。

With the gear pair of the curved-tooth gear coupling as the research object and based on the processing principle of curved-tooth gear ,a three-dimensional model was built for internal and exter-nal gears of the curved-tooth gear coupling .The model was then imported into the finite element anal-ysis software to analyze the stress distribution of internal and external gears of the gear coupling be-tween different obliquity .The strength check for gears was also made .On this basis ,the relations between gear loading capacity and dip of the curved-tooth gear coupling were eventually obtained .
