齿轮等效转动惯量计算理论验证

Theoretical verification of equivalent moment of inertia calculation of gears

在计算齿轮等效转动惯量时,已知等效转动惯量与各配合系统传动比平方成反比,但未有相关的理论计算加以说明。文章通过对定轴轮系及行星轮系的分析计算,理论验证前述公式的正确性,并为等效转动惯量的计算提供理论指导。

In calculating the equivalent moment of inertia of gears, the known equivalent moment of inertia is inversely proportional to the square of transmission ratio of each mating system, but there is no relevant theoretical calculation to explain it. Through the analysis and calculation of fixed shaft gear train and planetary gear train, the correctness of the above formula is verified theoretically, and the theoretical guidance is provided for the calculation of equivalent rotational inertia.
