    Influence of System Parameters on Nonlinear Dynamic Characteristics of the Herringbone Gear Transmission Under Different Coincidence Degrees by Wang Ji, Li Zhibin, Wang Sanmin, Wang Chunling

    Published 2024-01-01
    “…The appropriate coincidence degree of reasonable selection can improve transmission bearing capacity and ensure transmission stability, thereby improving the performance and reliability of the gear transmission system. The analysis of the influence of system parameters on system vibration characteristics under different coincidence degrees is of great significance for optimizing the transmission system performance, improving work efficiency and reducing fault risk. …”
