铁路车辆车轮往往因运行或制动而产生磨损,踏面形状改变而降低舒适性,导致运行噪声的加剧,从而对运行安全产生恶劣影响,所以每隔一定的周期要进行一次车轮削正。以前通常是每隔一、二年在车辆厂进行定期检修时,从车体下推出轮对,用车轮车床进行削正,花费一定的时间和人力进行车轮的维修,以确保行车安全。 Wheels of railway vehicles are often worn out due to running or braking, and the tread shape is changed to reduce comfort, leading to increased operational noise, which adversely affects operational safety. Therefore, wheel alignment is performed at regular intervals. In the past, it was common to roll out wheelsets from the body of a vehicle plant every other year or two when carrying out regular overhauls. The wheelset was used to correct the wheelsets and spent a considerable amount of time and manpower on wheel maintenance to ensure traffic safety.
