Early railway wagon loaded with sliding bearing axle box device

Early railway truck packed with 2020 - sliding bearing axle box device 09 - 23 axle box device is installed on the railway locomotive vehicle, set in the shaft neck or two shaft coupling wheelset and bogie frame car body parts, axle box device, depending on the type of bearing adopted by the axle box device can be divided into sliding bearing and rolling bearing axle box device. China's early railway truck axle box device is equipped with sliding bearing, general installation on the outside of the wheel, has now been replaced by no axle box rolling bearing device. Early loading using sliding bearing axle box device is mainly composed of axle box body, axle box cover, bearings, bearing plate, oil device and dust shield and so on, its purpose is to give wheel of the car body weight and load transfer, lubrication journal, reduce friction, reduce the running resistance. Mixer axle box body axle box body is under load, oil storage shaft parts, used for inclusion shaft neck and other parts, early made of cast iron, the late is generally made of cast steel. Friction pieces bearing and shaft neck and all the load on axle box body is passed to the shaft parts, by tile body and the surface of a layer of antifriction alloy. Pieces bearing plate bearing plate is installed on the axle box body and bearing load transfer between the function of parts, it's the above-mentioned like circular arc form, to improve the load distribution on the surface of the white metal. Mixer oil device to supply between bearing and shaft neck shaft oil to reduce friction device. By the oil volume, wooden pillow before and after the baffle, installed on the axle box body, the oil volume is full of shaft oil ( Lubricating oil) And contact with the shaft neck lower part. Vehicle shaft neck rotation, will shaft oil into the bush and shaft neck, forming oil film, make the dry friction into liquid friction. Mixer dust shield function of dust shield with axle box cover are the same, so also called axle box back cover, located within the interlayer of axle box body after the wall. （ Source: the resources of railway vehicle platform)
