The gearbox is the core component of the high-speed train power steering system, which isThe core unit for energy conversion and torque transmission in high-speed trains, gearbox workerThe performance directly affects the safety and reliability of high-speed train operation.At present, the gearbox configuration of high-speed trains can be divided into different types according to the box structureThere are two types of postures and integrated postures. Gearbox products for high-speed trains assigned by a certain railway bureauThe main brands include Angela, Qishuyan, and Frand. Among them, Angela and FranThe German gearbox is a split type; The Qishuyan gearbox is mainly of integral type.Due to insufficient reserved area for gearbox maintenance, only one type can be metGearbox maintenance. Decomposing inspection for configuration compatibility with up to 3 types of gearboxesRepair, by using intelligent logistics technology to analyze the differences in maintenance processes and techniquesImplement three types of gearbox maintenance in a limited space and design corresponding teethLayout plan for wheel box maintenance process.
Overview of Gearbox and Intelligent Logistics Technology
The gearbox mainly consists of a casing, output shaft, large gear, and a large gear shaftParts (bearings, bearing seats, sealing rings, end caps), small gear shaft (inputMore than 100 components, including shafts, small gear shafts, C-shaped brackets, couplings, etcComponent composition.The split type gearbox has an upper and lower box structure. Front of the boxConnected with a C-shaped bracket (or gearbox suspension rod), fix the gearbox to the structureOn the rack, the front end of the gearbox is equipped with an observation window for observing the master and slaveThe meshing condition of the moving gears. The bottom of the gearbox box has a certain inclination angle,And oil and drain plugs are designed at the bottom of the gearbox, and the lower box is also equipped with an oil level gauge observation window. The integral gearbox is mainly composed of a boxBody, large gear, small gear, bearings, suspension device, ventilation device, grounding deviceComponent composition of oil level gauge and oil level gauge. It can be seen that different brands of gearboxesThere are significant structural differences.
