首發時間:2023-05-10
摘要:針對行星傳動系統在運行過程中存在各部件載荷分配不均,從而影響傳動系統的平穩性的問題,本文以某兩級行星傳動系統為研究對象,引入級間相對浮動、齒側間隙、綜合嚙合誤差、時變嚙合剛度等內外部激勵,建立了考慮齒面磨損影響的傳動系統的平移-扭轉耦合非線性動力學模型。得到了齒輪動態嚙合力和齒輪副均載系數,全面分析了齒面磨損次數、有無級間相對浮動間隙時的綜合嚙合誤差、齒輪支承剛度對均載性能的影響規律,為深入研究行星齒輪系統平穩性奠定了理論基礎。

Study on the load sharing performance of planetary gear transmission system under multi-source excitation with tooth surface wear
Abstract:In view of the problem that the load distribution of each component was uneven during the operation of the planetary transmission system, which affected the stability of the transmission system. A two-stage planetary transmission system was considered as the research object, and introduced the internal and external excitation such as relative floating between stages, gear backlash, comprehensive meshing error, time-varying meshing stiffness, and established a translation-torsion coupling nonlinear dynamic model of the transmission system considering the impact of tooth surface wear. The dynamic meshing force of the gear and the load sharing coefficient of the gear pair were obtained, and the influence of the number of tooth surface wear, the comprehensive meshing error with and without the relative floating clearance between stages, and the gear support stiffness on the load sharing performance were comprehensively analyzed, which laid a theoretical foundation for the in-depth study of the stability of the planetary gear system
Keywords: two-stage planetary drive system multi-source excitation tooth surface wear dynamics load-sharing performance
