The Research Of The New Alex Inspection And Repair Method Of The FentTai Truck Department

In recent years, the development of China’s railway freight truck to high-speed, heavy load development, load 60t grade truck full stop,70t grade general railway freight into operation, 120km/h truck technology comprehensive application, marking China’s railway truck to achieve load from 60t to 70t level, the speed by 70,80km to 120km. In this process, the development of wheel axle technology has provided a good technical support for the high speed and heavy load of the railway freight transportation.Railway truck axle repair is under the framework of regular maintenance of vehicles, the implementation of to the repair condition main and changing parts repair and specialized repair auxiliary maintenance system. Wheel inspection and repair is an effective measure to eliminate the defects of the parts in time and eliminate the defects of all kinds of faults. The maintenance can prevent the axle to stop the operation, eliminate hidden dangers of accidents. How to use new technology, new equipment, new technology, so that the axle inspection and repair technology to better adapt to the current variety of hybrid, wheel axle failure frequency, complex situation, is the current one of the new topics of the wheel.In this paper, we use the method of literature, investigation, action research and observation. Based on the analysis of the optimal setting of the axle failure mode, the new technology of automatic test, bearing, wheel neck automatic detection, matching, computer controlled 3000 magnetic particle inspection, new technology and equipment, the problem of the new type of axle repair process line and the new type of vehicle, the problem of the hidden trouble of wheel axle is solved. In particular, by improving the accuracy of the rotation of the wheel, reducing the risk of the rotation of the wheel, through the bearing and the wheel neck of intelligent matching, eliminating the problem of the pressure caused by the interference of the bearing and the shaft neck, so that the existing problems in the process of the maintenance of the original shaft is effectively solved.Based on the actual situation of the fault during the process of the railway freight car wheel and analysis of the original wheel maintenance process and the selection of the equipment for the maintenance of the wheel.We updated the inspection equipment and wheel assembly line for raise up the quality of the wheel and ensure the Transportation safety.
