摘要
"S"形齿轮作为一种具有新型齿廓的齿轮,目前有关研究很少。通过分析"S"形齿轮的齿廓结构特点,以其齿廓曲线方程为基础,给出了"S"形齿轮的参数化建模方法。基于Pro/E平台编制生成"S"形齿轮齿廓的参数化程序,利用笛卡尔坐标方程曲线以及实体化特征操作,实现了"S"形齿轮的三维参数化模型的构建。采用Pro/E集成的有限元模块Pro/MECHANICA建立了"S"形齿轮的有限元分析模型,得到静态分析、失稳分析、模态分析受力云图,并将其与渐开线齿轮进行了接触应力对比分析。分析结果表明,"S"形齿轮具有传动精度高、承载能力大等优点。
As a kind gear having a newgear tooth profile,at present,the current researches on ＂ S ＂-shaped gear are very little. By analyzing the structure characteristics of tooth profile of ＂ S ＂ shaped gear,Parametric modeling approach was given based on its tooth profile curve equation. ＂ S ＂ shaped gear parametric program was created in Pro / E,and three-dimensional parametric model of ＂ S＂ shaped gear was established by using Cartesian equations curve and operating materialized characteristics. Finally by using integrated finite element module Pro / M ECHANICA in Pro / E to establish the finite element analysis model of ＂ S ＂ shaped gear we could get the stress cloud about static analysis,buckling analysis,modal analysis.Then,we made comparison about the contact stress of ＂ S ＂ shaped gear to the involute gear. The analysis results showed that, ＂ S ＂ shaped gear had the advantages of high transmission precision,bearing large capacity.
