摘要

基于赫兹理论,建立了摆线钢球传动啮合刚度模型,并对啮合刚度进行无量纲化。分析了结构参数对啮合刚度的影响规律,并利用摆线钢球啮合副的啮合刚度推导出行星传动部分的等效扭转刚度计算公式。在综合考虑输入轴刚度、输出轴刚度及行星传动部分的等效扭转刚度基础上,建立了NN型二级摆线钢球传动的4自由度扭转振动模型,并进行了实例计算。

Abstract

Based on Hertz theory,the engagement rigidity model of the cycloid ball transmission is established,and the engagement rigidity is converted to the dimensionless form. The influence regularity of the structural parameters on the dimensionless engagement rigidity of cycloid ball engagement pairs is analyzed. The equivalent torsional rigidity formula of the planetary transmission section is deduced by using the engagement rigidity. On the basis of considering the the equivalent torsional rigidity of the input shaft,the output shaft and the planetary transmission section,the 4 freedoms torsional vibration model of the NN cycloid ball transmission is established,and the analysis of example is carried out.
