摘要：设备在运转过程中会产生波动负载，导致轴系中轮系的啮合刚度及啮合力产生变化。根据能量法构建直齿轮时变啮合刚度计算模型，并建立考虑负载耦合影响的啮合刚度修正模型。在平行轴弯－扭耦合齿轮传动系统下，采用Newmark时域算法计算，对比无波动负载和考虑波动负载影响下的齿轮时变啮合刚度差异，并分析设备负载对平行轴齿轮啮合刚度及啮合力的影响。同时，通过行星轮系相位调谐公式的推导，分析设备负载对行星轮系啮合力的影响。结果表明，设备的波动负载会对齿轮啮合力产生边频调制影响；对于均布型行星轮系，当中心轮受到传动轴系的设备波动负载影响时，相位调谐模型将失去其调谐规律。

Abstract：The device generates fluctuation load during operation, which leads to the changes in meshing stiffness and meshing force of the gear system. In this paper, the spur gear time-varying meshing stiffness calculation model based on the energy method and a meshing stiffness correction model considering the load-coupling effect are established. Under the transverse-torsional coupling gear transmission system, the Newmark time domain algorithm is used to compare the differences of meshing stiffness under no fluctuate load and fluctuate load and analyze the effect of equipment load on meshing stiffness and meshing force of the parallel shaft gear. At the same time, the impact of equipment load on meshing force of planetary gears is further analyzed through the derivation of the planetary phasing formulas. The results indicate that the fluctuant load of the device will generate boundary modulation effect on the gear meshing force, and in terms of the equally spaced planetary gear set, when the center gear is affected by the fluctuant equipment load, the tuning law of the phasing model will no longer work.
