A general survey of the vibration of the locomotive axlebox bearings of Taifan was carried out to determine if the bearing had a faulty wheel pair. The decomposing inspection found that each bearing had problems such as pitting, peeling, and strain, and some of the bearings had serious faults. Other serious faults in the travel department, such as the small clearance of the bearing of the locomotive, the dust-proof ring of the axle box, poor meshing of the gears, etc., prevent many accidents.
In addition, we carried out the top wheel inspection of traction motor bearings and axle box bearings of all types of locomotives and the ground diagnostics of the traction motor bearings of spare parts. We also included small and minor repair scopes, and we also provided bearings and transmissions for main generators with fault prediction. Bearings were tested and diagnosed, many bearing quality problems were discovered, locomotive safety was ensured, and the quality of locomotives was improved. Conclusion The fault diagnosis technology for locomotive bearing is a new technology with strong practicality. After many years of promotion, it has been widely used in the locomotive system and has achieved good results, proving its value and significance.
From the successful experience of many locomotive depots, it can be seen that in addition to the technical personnel and operators mastering the basic principles of diagnostic technology and accumulating experience, it is also necessary to pay full attention to the management of diagnostic work. This is indispensable and it is also The key to the successful application of this new technology. It is suggested that the diagnosis of locomotive bearing should be carried out actively and in depth. The personnel should be properly organized and equipped, the locomotive bearing diagnosis work should be carried out on the locomotive repair process, and the corresponding repair process should be formulated to ensure the safety of the locomotive and gradually rationalize the maintenance.
Casting mold is a method of casting liquid die forging, a special die - casting die - forging machine.The basic process is: the metal liquid is first filled into the mold cavity with low speed or high speed casting, and the mold has a movable cavity surface. It is forged under pressure along with the cooling process of the metal liquid, which can not only eliminate the shrinkage cavity and porosity of the blank, but also make the inner structure of the blank reach the forged broken grain.The comprehensive mechanical properties of blank have been improved remarkably.
