本文对动力谐波齿轮传动中柔轮的几何形状的变形进行了分析和计算。应用弹性薄壳理论、弹性动力学变分原理和功的互等定理与位移叠加原理的等价性等数学、力学原理推导和建立了柔轮在动载状态下的位移方程和柔轮中性层向径流动方程,并针对具体杯形柔轮计算了在额定输出扭矩状态下柔轮的变形。通过实验测试确定了柔轮与刚轮相啮合时的啮合区及其力的分布规律。应用径向位移方程建立了求柔轮与发生器园盘间静顶起时包角及其上力分布规律的数学模型。建立了在载荷状态下柔轮与发生器园盘间的力分布规律数学表达式。通过对特定的杯形柔轮的实验分析和计算,证明了本文建立的柔轮位移方程是正确的。
In this paper, the deformation of flexible wheel in power harmonic gear drive is analyzed and calculated. The elastic shell theory, elastic dynamics variational principle and reciprocity theorem of work and the equivalence of displacement superposition principle are used to deduce and establish the displacement equation of flexspline under dynamic load and the flexural neutrality Layer to radial flow equations, and for a specific cup-shaped flexure calculated at the rated torque output state of the flexible wheel deformation. Through the experimental test, the meshing area and force distribution of the flexspline and the rigid wheel are determined. The radial displacement equation was used to establish the mathematical model of the distribution angle of the wrap angle and its upper force between the flexible wheel and the generator disc during static jacking. The mathematical expression of the law of force distribution between the flexspline and the generator disk under load is established. Through the experimental analysis and calculation of a specific cup-shaped flexspline, it is proved that the flexspline displacement equation established in this paper is correct.
