| Rail grinding vehicle is the importance technical equipment of high-speed,heavy railway and urban rail transit lines to repair. CMC-16 switch grinding vehicle can be a continuous grinding operation for various lines. Elimination the rail wear and various other local defects of rail. In transmission system of the rail grinding vehicle,the running gear box is its key core components of traveling system for the vehicle. Its performance can directly affect the safety,comfort and handling of the grinding vehicles. It is the driver of operation and high-speed running of the vehicle.Nowadays,running gear box is loading rail grinding vehicle due to unreasonable design,there are many problems,the running gear box low performance,poor reliability,high failure rate. There are run-time temperature is too high,low efficiency in chang gear,locking is not reliable,shift locking mechanism easily is damaged,inadequate lubrication and seal is not reliable etc. Thus affected the use efficiency of the vehicle,it is difficult to meet customer needs. The key technology of rail grinding vehicle gear box design and manufacture,it is an important factor which has been troubled by the rapid development of rail grinding technology in our country. This article,running gear box used in CMC-16 switch grinding vehicle is the main object of study.At first,here carried out a comprehensive study and analysis grinding vehicle on the overall technical parameters,the use of conditions and the gearbox design requirements,through theoretical calculation and analysis. System parameters on the gear box has been designed,it provide a basis for further study. Second,combination the use of status quo of gear box used in rail grinding vehicle in china,for the key design techniques of running gear box for CMC-16 switch grinding vehicle. From the theoretical analysis,calculation and testing argumentation aspects. Respectively,research,analysis and design on the key design technology of its,such as box,shift locking mechanism,lubrication system, sealing system etc. Optimize the integrated performance and improve the reliability of the gear box. Overcome the shortcomings is exist to the gear box of grinding vehicle.At last,the main design performance indicators of the design and development gear box were tested demonstration,such as,lubrication and seals systems proper- ties,heat load performance and libration of the gear box,box strength,maneuver- ability of the shift locking mechanism and design and calculation accuracy etc. Through this study,is used to overcome the exist many shortcomings of gearbox used in grinding vehicle and for future research in related fields to lay a good found- ation in the future.This article merges the design,calculation,modeling,analysis and experimental verification into one study,which possesses an important meaning to raise the design standard and efficiencu of the gear box. |
