摘要

为了探明直径13 m级大型岩石掘进机(Tunnel boring machines

TBM)主驱动传动齿轮系统在掘进工况载荷下多源(含10组动力源)汇流的均载特性，该文采用有限元法建立了TBM主驱动系统瞬态动力学有限元模型，研究了主轴承游隙、主动驱动小齿轮在不同位置情况下各齿轮啮合接触力大小以及齿轮均载性能。研究结果表明：通过主轴承游隙以及主动驱动小齿轮位置调整，可以大幅提升TBM主驱动系统多源汇流的均载性以及同步性。同时，可以通过提升制造、安装精度以及大齿轮刚度的方式来减小齿轮啮合接触力波动。

Abstract

In order to explore the load sharing characteristics of multi-source (including 10 groups of power sources) of the large tunnel boring machines(TBM) main drive gear system with a diameter of 13 m under the real driving conditions

the finite element method to establish the transient dynamic finite element model of the TBM main drive system is used. The main bearing clearance

the meshing contact force of each gear in different positions of the active drive pinion

and the gear load sharing performance is mainly studied. The research results show that the load sharing and synchronization of multi-source confluence of TBM main drive system can be greatly improved by adjusting the main bearing clearance and the position of the active drive pinion. Meanwhile

the fluctuation of gear meshing contact force can be reduced by improving the manufacturing and installation accuracy and increasing the stiffness of the large gear.
