High speed train railway gearbox PSH series

NGC gearbox drives for high-speed trains have been developed in-house through a detailed process of vehicle motion simulations in different operating conditions. A variety of analytical techniques were applied, to ensure that the gearbox performance meets all operating requirements for high-speed railway, including finite element analysis, thermo mechanical analysis, modal analysis, and labyrinth seal analysis. Technical characteristics: (1). Optimized structural design for high power density, variable load and high-frequency vibrations ensures the gearbox rating; (2). High-strength aluminum alloy housing； (3). Maintenance interval >2.4 million kilometers; (4). Suitable for extreme environments from -40℃ to +40℃. Typical cases: Supplied to an European end-user for use on AGV/TGV high-speed trains. Developed an EMU gearbox for 250km/h PSH370-01 high-speed trains Developed an EMU gearbox for 380km/h PSH380-01 high-speed trains
