铁道用车轮由轮芯和轮箍组合而成,已经在铁道上用了100多年。由于铁路运输十分繁忙,速度已提高到200公里/小时,车辆轴重增加到245千牛顿,轮箍的可靠性和耐久性对机车的运行已显得十分重要,因为这和铁道运输的安全密切相关。在俄罗斯,轮箍是按ΓОСТ 398—81《宽轨铁路及地铁用碳素钢制轮箍技术条件》、ΓОСТ 3225—80《宽轨铁路机车用轮箍类型和尺寸》以及ΓОСТ5000—83《车辆及煤水车轮箍尺寸》供应的,上面列举的标准中,其技术
The railway wheel is made up of wheel core and wheel rim, and it has been used in railway for more than 100 years. Since the railway is very busy, the speed has been increased to 200 km / h and the axle load of the vehicle has increased to 245 kilo-newtons, the reliability and durability of the wheel rim have become very important for locomotive operation because it is closely related to the safety of railway transportation . In Russia, the tires are manufactured according to ΓОСТ 398-81 Technical requirements for carbon steel wheels for wide-gauge railways and subways, ΓОСТ 3225-80 “Types and dimensions of tires for wide-gauge railroad locomotives” and ГОСТ 5000-83 “vehicles And coal wheel rim size ”supplied, the above cited criteria for its technology
