【摘要】 对过盈配合的装配,方法通常是加热使孔胀大超过过盈量然后把轴和套装配到一起。文中以不锈钢材料为例,对套筒进行热变形分析,然后用正交试验方法安排相关参数求解内孔变形量,最后对数据进行逐步回归分析,得到最大变形量和最小变形量的逐步回归方程,为加热装配提供一定的参考。更多还原

【Abstract】 For Interference fit assembly,the hole is heated and swelled more than magnitude of interference,then the shaft are assembly together.Taking stainless steel as an example,the thermal deformation of the sleeve is analyzed.Then orthogonal experiment method is used to arrange the relevant parameters for solving the deformation of inner hole.Finally egression analysis method is used to process the calculated data,stepwise regression equation of the maximum and the minimum deformation amount.The analysis results can provide a reference for the heating assembly.更多还原
