Abstract:

Taking spiral bevel gear grinder with six axes five linkages as the object, multi-body system theory was utilized to establish the grinder synthesis error model and obtain six degrees of freedom error expressions in this model as well as the experimental confirmation. Additionally, the changing rule between the six errors from three kinds of movements of the spindle and the grinding wheel tool point six degrees of freedom errors were analyzed separately. The error tendency of teeth space of gear, helix angle, pitch, tooth profile was discussed. This study offers a theoretic basis for the design and the error compensations of spiral bevel gear grinder with six axes five linkages.

Key words: six axes five linkages, spiral bevel gear grinder, error model, analysis

摘要：

以六轴五联动螺旋锥齿轮磨床为对象，运用多体系统理论建立了磨床综合误差模型,得到了此模型的6个自由度误差表达式，并对其进行了实验验证。分析了砂轮主轴三种运动所产生的6个误差与砂轮6个自由度误差的变化规律，并由此讨论了对所加工齿轮的齿距、螺旋角、周节、齿形等误差的影响。
