当转子支架采用无轴结构时,由于轮毂段的扭转刚度大大减弱,导致扭矩在上下圆盘中分配不均,因而两个圆盘与轮毂焊缝的剪应力不再相等。为了准确计算这两处焊缝的剪应力,必须解决扭矩在两个圆盘中的分配问题。本文详细考虑了筋板和支臂的作用以及筋板对圆盘变形的影响,全面分析了无轴结构转子支架的扭矩分配问题。 When the rotor support adopts a shaftless structure, the torsional stiffness of the hub segment is greatly weakened, resulting in the uneven distribution of torque in the upper and lower disks, so that the shear stress of the two disk and hub welds is no longer equal. In order to accurately calculate the shear stress of these two welds, the problem of torque distribution in both disks must be solved. In this paper, the effect of ribs and arms and the effect of ribs on disc deformation are considered in detail, and the torque distribution problem of rotor shaft without shaft structure is analyzed in detail.
