摘　　要：在研究盾构机及行星齿轮机构的基础之上,针对盾构机刀盘驱动系统,提出一种新型盾构机双驱动大功率行星齿轮传动系统,分析了传动系统的原理及其结构;建立了新型传动系统的运动学模型,对该系统的传动特性进行了分析,获得了系统的传动比、系统内部的转速、扭矩的关系和变化规律;通过对比简化实验得到的结果与理论计算得到的结果,其变化规律基本一致,验证了数学模型及分析方法的正确性。双驱动大功率行星齿轮传动系统具有传动比大、承载能力强的特点,能实现低转速、大扭矩输出的功能,满足盾构机的基本工作要求,不仅可取代传统的多个电机同时驱动多个减速器的传动系统,还能实现3种不同型式的盾构机传动系统功能。On the basis of studying shield machine and planetary transmission,to address cutting drive system of shield machine,a novel dual drive planetary transmission system with large capacity is presented,and its principle and structure are analyzed.Through establishing a new kinematical model of the transmission system and analyzing its characteristics,the transmission ratio,rev and torque relationship and changing rules within the system are acquired.By comparing the simplified experimental results with theoretical results,it is shown that the variation is basically the same,which verifies the correctness of the model and analysis method.The high-power dual-driven planetary gear transmission system with great transmission ratio,strong carrying capacity,can perform the function of low-speed and high-torque output,and meet basic requirements of shield machine.It can not only replace the traditional multi-driven transmission system,but also achieve the transmission function in three different types of shield machine.
