摘要

提出了耦合弹性支承的齿轮传动系统等效模型,引入多维弹簧单元组合等效轴承与齿轮箱弹性,将"传动轴-轴承-齿轮箱"3个弹性支承件之间以及齿轮箱多个轴承孔之间的耦合关系表述为弹性支承系统的位移约束方程,并耦合齿轮有限元接触分析模型形成齿轮传动系统的性能分析方法。以某单级斜齿轮轴系为例,应用该方法分析了支承形式和刚度对其传动性能指标的影响,包括系统传动误差和齿面接触应力分布,结果表明,该方法相比经验公式计算方法更真实、全面地反映了轴系支承刚度特性对其传动性能的影响。研究工作对轴系支承结构的刚度设计有指导作用。

Abstract

Introducing the combination of multi-dimension spring elements as the equivalent of elastic bearings and gearbox,an equivalent model of gear drive system coupled with elastic supports is proposed,with the coupling relationships between the shaft-bearing-gearbox supports and between the bearing holes of gearbox expressed as the displacement constraint equations of elastic supports. Combining with the FE contact analysis model of gear set,an analysis method of transmission performance is established. Taking a single-stage helical gear train as an instance,the influence of the supporting forms and rigidity on transmission performance indexes,including transmission error and the contact stress distribution on tooth surfaces,is analyzed by using this method. The analysis results indicate the method reflects the influence of supporting rigidity characteristics on transmission performance more veritably and comprehensively than empirical formulas. A guidance for the rigidity design of supports is provided.
