Railway wagon wheel axle repair system set up and its main basis

Railway wagon wheel axle repair system set up and its main basis - 2019 05 - 22 railway wagon axle repair are the framework of preventive maintenance, the van in life management system, implement with state repairing is given priority to, in a fix and specialized concentrative maintenance of system, and adopt advanced inspection method. Axle repair as one of the content of the vehicle maintenance, mainly combined with simultaneous vehicle maintenance, vehicle maintenance time and maintenance ability, its maintenance system and truck maintenance system mutual constraint, mutual attachment, but relatively independent, decomposition or replace down from the vehicle axles according to its own maintenance system maintenance, axle repair system itself including axle ( Wheel to) , bearings and other parts of maintenance system, relatively independent each other, influence each other. Axle repair system set up mainly considering two factors: the rules of the development of the fault occurred, vehicle use and maintenance of the economy. Wheel shaft failure forms and rules of basically has the following kinds: 1) Fatigue. Accessories under the action of alternating stress, crack and expand and cause damage, usually with the vehicle running time ( Or km) , the material of accessories, vehicle load, speed and other factors, is the main basis that axle repair system Settings, and set up one of the main basis of bearing maintenance system. 2) Wear and tear. Because of friction disc surface state, dimensions, shape and quality change caused by damage, usually with the vehicle's running time ( Or km) , parts of material, vehicle load, speed and other factors, is the main basis of wheels overhaul system Settings. 3) The material aging. Grease, accessories material or environment medium produces chemical reaction with the outside world and make the oil and accessories irreversible changes in microstructure and property, produce parts damaged, usually is refers to the corrosion for metal, for oil is bad, for synthetic materials such as rubber, engineering plastics is refers to the aging. Usually with the vehicle running time ( Or km) And using the environment and the surrounding medium, oil metamorphism is the main basis of bearing maintenance system Settings. Maintenance system set up in addition to the affected by technology, the key also affected by the economy. In order to improve the shaft maintenance economy, should be through the extension of the repair cycle, reduce the maintenance frequency, increasing the service efficiency of the vehicle; Also, consider the means of inspection, repair, reasonable and economic, improve service ability, reduce maintenance cost. （ Source: the resources of railway vehicle platform)
