一、车辆滚动轴承轴温的形成、种类、检测、乘务中的判断和原因。 1、滚动轴承热轴的形成。车辆在运行中,由于轴承内环和滚柱、滚柱和外环滚道之间、轴承和防尘板之间、在各种外力的作用下相互摩擦产生热量,促使轴承发热,形成轴温。轴温升高或降低与列车运行速度、时间、气温和车辆本身状态、线路状况有直接关系。通过佳——大区 First, the formation of the vehicle rolling bearing shaft temperature, type, testing, crew judgment and reasons. 1, the formation of rolling bearings hot shaft. Vehicles in operation, due to the bearing inner ring and roller, roller and outer ring raceway, between the bearing and the dust board, in a variety of external forces under the friction of each other to produce heat to promote bearing fever, the formation of shaft temperature . Axle temperature increase or decrease with the train speed, time, temperature and the vehicle itself, the status of the line has a direct relationship. Through good - big area
