摘要

建立了盾构机刀盘四齿轮并联驱动系统的动力学方程,运用UG软件建立了该系统的三维模型,并利用ADAMS软件对该系统进行了动态仿真,分析了啮合阻尼、啮合刚度、齿侧间隙和主动齿轮布置方式等因素对齿轮副载荷均衡性的影响。研究表明,各个齿轮副啮合刚度和啮合阻尼相差越大,载荷分配就越不均匀;齿侧间隙在驱动载荷变化时对载荷均衡性影响较大;主动齿轮不同布置方式对传动系统的传动平稳性有较大影响。分析结果可为多齿轮并联驱动系统的设计与制造提供理论依据。

Abstract

The dynamics equation of the four gears parallel drive system of shield machine cutter is established.The 3D model of the four gears parallel drive system is established by using the UG software.The dynamic process of the four gears parallel drive system is simulated by using the ADAMS software.Then the influence of meshing damping,meshing stiffness,backlash and distribution of driving gear on the load sharing are also analyzed.The research shows that the larger the difference between meshing stiffness and meshing damping is,the more uneven the load sharing is,when the driving load changes,backlash has a larger effect on the load balance,the different distributions of driving gear have rather a great impact on the stability of driven system.The results can provide theoretical basis for the design and manufacture of the four gears parallel drive system.
