摘　　要：在盾构机传动系统中多个小齿轮与大齿轮同时啮合系统的研究中,推导了各齿轮间的啮合力和扭矩计算公式,发现小齿轮和大齿轮间的啮合力和扭矩与相对位置、啮合刚度及阻尼有关。在Hertz弹性碰撞理论基础上,利用ADAMS软件仿真分析了不同工况下大、小齿轮之间的啮合力。仿真结果表明,在理想状况下各个小齿轮和大齿轮间的啮合力是相等的;然而在非理想状态下,齿轮的安装精度、小齿轮的数量、启动延迟以及工作载荷等对啮合力的影响显著。研究结果对盾构机小齿轮/大齿轮减速单元的结构设计优化和盾构机传动故障分析具有重要的参考价值。The dynamic model of the muhiple active pinions meshing the center passive large gear of the shield tunneling machine was studied in the paper. First, the gear meshing force and torque design formulas were deduced respectively. And we found that the forces and torques among the pinions and large gear are related to their relative position, mesh stiffness and mesh damped. Subsequently, based on the elastic collision theory of Hertz, the meshing force among the pinions and large gear were simulated by the use of ADAMS considering different conditions. The re- suits show that the meshing forces are equal among different pinions and large gear under ideal condition, while the number and installation accuracy of the active pinions, start delay and working load make significant influence of mesh force under nonideal conditions. The study has great significance for the design of shield machine cutterhead driving system. Also, it is of great value for the analysis of gear transmission failure.
