摘要

摘要: 为改善面齿轮-圆柱齿轮两次载荷分流传动构型的均载特性,考虑齿轮的中心偏移、轴与轴承的承载变形等因素,依据构型的变形协调条件和力矩平衡方程,建立了传动构型的静力学模型,研究了轴的扭转和支撑刚度对均载特性的影响。结果表明:输入轴扭转刚度对均载特性几乎没有影响;分扭轴扭转刚度取合适的比值,则面齿轮分扭传动级可获得较好的均载特性,但圆柱齿轮分扭传动的均载特性几乎无变化;减小双联齿轮轴扭转刚度或增加双联轴支撑刚度可提高该构型的均载特性。因此,为提高该传动构型的均载特性,轴的扭转刚度和支撑刚度需采用参数匹配的设计方法。

Abstract: According to the deformation coordination condition and the moment balance equation of the configuration, a static model was developed to enhance the load sharing characteristics of the face gear and cylindrical gear twice load split transmission configuration, taking into consideration the center deviation of gears, bearing deformation of shaft and bearing, etc. The influence of the torsional stiffness and supporting stiffness of the shaft on the load sharing characteristics was studied. The results showed that the input shaft torsional stiffness had little influence on the load sharing characteristics. When the ratio of the torsional stiffness of the split torque shaft was appropriate, the face gear split torque drive could obtain better load sharing characteristics, but the load sharing performance of the cylindrical gear split torque drive remained almost unchanged. Reducing the torsional stiffness or increasing the supporting stiffness of the compound gear shafts could improve the load sharing characteristics of the whole configuration. Therefore, in order to improve the load sharing characteristics of the transmission structure, the torsional stiffness and supporting stiffness of the shaft need to adopt the method of parameter matching design.
