轮轴几何参数对压装合格率的影响研究

Study on Influence of Geometric Parameters of Wheel Axle on Pressing Load

在轮轴压装时,相关单位应分析轮轴自身圆柱度、过盈量等几何参数的变化对产品合格率的影响。本文通过对轮轴压装整个过程中车轮与车轴的受力分析,找出有关轮轴压装应力曲线的影响因素,同时针对这些影响因素提出合理性建议,防止出现曲线末端平直的现象,提高轮轴压装的合格率。

In the wheel pair pressing,the relevant unit should analyze the influence of the change of geometric parameters such as the cylindrical degree and the excess amount of the axle on the product qualification.This paper analyzed the force of the wheel and axle during the whole process of axle pressing,found out the influencing factors of the stress curve of wheel to press,and put forward some reasonable suggestions for these influencing factors,so as to prevent the phenomenon of straight curve end straightening and reducing ton,and improve the pass rate of wheel to pressing.
