摘要
为确保飞剪机齿轮与曲轴过盈配合的可靠性,根据齿轮轮毂与曲轴的实际结构参数和工况,修正过盈量的取值范围,采用有限元法对过盈装配过程进行仿真分析,并结合实际压装数据验证仿真模型的正确性.在此基础上,利用正交分析法对影响压装效果的因素进行敏感性分析,结果表明:影响最大压装力的参数依次为结合面锥度、摩擦系数和过盈量;过盈量和摩擦系数对承载能力的影响较为显著,结合面锥度的敏感性不显著.
Abstract
To ensure the reliability of the interference fit between the gear and crankshaft of the flying shear mechanism,based on the actual structural parameters and working conditions of the gear hub and crankshaft,the range of interference values are adjusted,and the interference fit assembly process is simulated using finite element method.The correctness of the simulation model is validate combing actual press-fitting data.On this basis,the sensitivity analysis is conducted on the factors that affect the pressing effect using orthogonal analysis method.The results show that the parameters that affect the maximum pressing force in sequence are the joint surface taper,friction coefficient,and interference fit value;the interference fit value and friction coefficient have a significant impact on the bearing capacity,while the sensitivity of the joint surface taper is not significant.
