与铁路行车安全紧密相关的问题之一,就是缺少用于批量检测轴承内圈在轮对车轴上套装可靠过盈量的仪器。目前所使用的常规方法,其可靠性较低。因为它是以套装之前测量轴承圈和轮对车轴的直径为依据的,并没有考虑到轴承圈的加热和与车轴的机械连接,这些随机工艺过程中的许多因素 One of the problems that are closely related to the safety of railway traffic is the lack of instruments for mass checking the reliable interference of sleeves on the axles of the inner ring of the bearing. The conventional methods currently used are less reliable. Because it is based on measuring the diameter of the bearing ring and the wheelset axle prior to the set-up and does not take into account the heating of the bearing ring and the mechanical connection to the axle, many of these random process factors
