摘要
盾构机主轴承是盾构机的主要部件,对盾构机的使用寿命起到至关重要的作用。文中运用理论和经验公式对盾构推力和刀盘扭矩进行了计算和比较,并对盾构机主轴承进行了校核计算,对新型盾构机主轴承的研发具有一定的参考意义。
Main bearings of shieht TBM is the main component which affects the service life of the shieht direclly. Theoretical and empirical formulas are used to calculate and compare shiehl thrust force and the cutting wheel torque. Based on the shield stress analysis and calculation, check analysis of the main bearings are carried out. The result can provide a certain reference value for the design of the main bearings.
