铁路客车轮对的组装质量,直接关系到铁路客车的行车安全及平稳状况。反映轮对组装质量的好坏,目前只能从压装曲线来体现。但由于多种因素如:轮轴表面粗糙度、几何形状、材料的机械性能、润滑油、组装温度、压入速度以及过盈量等等一些因素的影响,压力曲线的形状只能间接的反映其轮对的组装质量。因此,把压装曲线做为检验轮对质量的唯一标准,是不合适的。
The assembly quality of railway passenger wheel pairs is directly related to the safety and smooth running of railway passenger cars. Reflect the quality of the wheel assembly is good, now only from the press-fit curve to reflect. However, the shape of the pressure curve can only indirectly reflect the influence of many factors such as the surface roughness of the shaft, the geometry, the mechanical properties of the material, the lubricant, the assembly temperature, the pressing speed and the amount of interference. Wheelset assembly quality. Therefore, the pressure curve as the only test wheel quality standards, is not appropriate.
