Shield gear box reducer

Shield reducer is mainly used for various EPB, TBM, mud-water balance and other shield TBM cutter drive, screw conveyor and segment assembly machine, adapt to the harsh underground structure, meet the needs of hard rock excavation, transmission structure adopts multi-stage planetary gear transmission, including sun wheel, planet wheel, inner gear ring. During the research and development process, through the force analysis, finite element design and motion simulation of the shield machine, and the optimization of load sharing characteristics, after many iterations, the design scheme that most conforms to the working condition is proposed to meet the high load capacity and lightweight requirements of the shield machine reducer. In the manufacturing process, the material, size, tolerance, heat treatment and so on of all the internal parts have gone through strict quality control to ensure the reliability and durability of the shield reducer. The reducer of shield machine works undergroun…
