The NGC tunneling machine traveling gearbox is a sealed gearbox product driven by differential planetary gears, usually including two-level to three-level planetary gear structures. The input of the gearbox is achieved using a hydraulic motor that drives sun gears, with output realized through a final gear ring. In addition, normal close brakes are closed with a spring and hydraulically initiated. The tunneling machine travelling gearbox has a series of advantages that include large bearing capacity of unit volume, compact structure, large speed ratio and convenience for installation and arrangement. The product is thus widely applied in the engineering machinery and coal mine machinery industries.
Output: 60 kN.m～160 kN.m
Range of speed ratio: 19.7～185.4
