轮对是机车车辆上的一个重要部件,防止车轴疲劳折损是保证铁路运输安全的一种措施。为了防止轮座在装轮或退轮过程中的拉伤、过早地产生疲劳源、延长使用寿命、杜绝疲劳切轴事故发生,国外研究了注油装轮和注油退轮工艺。据报道,该工艺已得到较多的应用。在我国,组装轮对的一般方法是用压力机把车轴压入车轮的毂孔。这种装轮工艺比较简单,但在轮座与毂孔的配合面上会产生不同程
Wheelset is an important part of the rolling stock, to prevent fatigue damage axle is a measure to ensure the safety of railway transport. In order to prevent the wheel seat during loading or unloading, fatigue source prematurely, prolonging the service life and avoiding the accident of the fatigue cutting-axis, the overseas research on the loading and unloading wheel and oiling and unloading technology. It is reported that the process has been more applications. In our country, the common method of assembling a wheelset is to use a press to press the axle into the wheel hub hole. This wheel loading process is relatively simple, but the wheel seat and hub hole with the mating surface will have a different course
