摘　　要：建立了变速器齿轮与齿轮轴系统的有限元模型,并对其进行有限元分析,以计算齿轮轴变形和轮齿接触应力,分析变速器齿轮轴变形对齿面接触状态的影响。通过与经典方法计算结果的比较,表明所建立的齿轮与齿轮轴系统有限元模型,不但可准确计算齿轮轴变形和齿面接触应力,且能综合分析齿轮轴变形对齿面接触区域的载荷分布、轮齿间载荷分配和齿面接触应力的影响,为更全面、精确分析变速器齿轮的齿面接触状态和载荷分布,预测齿轮疲劳寿命提供依据。A finite element model for the gear and shaft systerm is developed,on which a finite element analysis is conducted to calculate the deformation of gear shaft and the contact stress of gear teeth,and analyze the effects of gear shaft deformation on the contact state of teeth surfaces.Through comparing the results with that of calculation by classical method,it is shown that using the finite element model built can not only calculate shaft deformation and teeth contact stress,but also comprehensively analyze the effect of shaft deformation on the load distributions in teeth contact area and between teeth as well as the contact stresses of teeth surfaces,providing bases for more thoroughly and accurately analyze the teeth surface contact state and load distribution of transmission gears and predict the fatigue life of gears.
