Abstract

Planetary gear train is widely used in large heavy-duty machineries such as helicopters and ships due to its large transmission ratio, strong bearing capacity, and small size. In this paper, and the load sharing ratio (LSR) and overall transmission error (TE) of a two-stage double-helical planetary gear train are studied. Firstly, the static balance equations of the double-helical planetary gear train are established. Then, the LSR under different mesh phasing and the overall TE are obtained by solving the equations. Finally, different errors such as pinhole position and eccentricity error are taken into consideration and the influence of errors on load sharing ratio and transmission error are analyzed. The results show that the excitation frequency of transmission error is related to the number of planet gears and mesh phasing and the LSR is related to the mesh phasing, especially to the sequentially phased transmission. It is also concluded that the excitation frequency of the output element of the two stages can be seen as the superposition of the mesh frequencies of each stage and that the studied errors have a significant impact on the LSR and the TE. Keywords: Double-helical planetary gear; Meshing phase; Load Sharing Ratio, Transmission Error.
制造误差对两级行星齿轮系性能的影响
行星齿轮系以其传动比大、承载能力强、体积小等优点,广泛应用于直升机、船舶等大型重型机械中。本文研究了两级双斜齿行星齿轮系的均载比(LSR)和总传动误差(TE)。首先,建立了双斜齿行星齿轮系的静平衡方程。然后,通过求解方程,获得了不同网格相位下的LSR和整体TE。最后,考虑了不同的误差,如针孔位置和偏心误差,分析了误差对均载比和传动误差的影响。结果表明,传动误差的激励频率与行星齿轮数量和啮合相位有关,LSR与啮合相位有关。还得出结论,两级输出元件的激励频率可以看作是每级啮合频率的叠加,所研究的误差对LSR和TE有显著影响。关键词:双斜齿轮;啮合阶段;负载分担比,传输错误。
