Research on Slippage Analysis and Improvement Design of EBZ200H Roadheader
In view of the slippage problem of EBZ200H roadheader,the causes of slippage of driving mechanism were analyzed.The results show that the main causes of slippage of driving wheel of roadheader are the few meshing teeth between driving wheel and crawler and the difficulty of slag discharging.By improving the structure of the driving wheel of the driving mechanism of the roadheader,including pitch,tooth width,row number of teeth,etc.,the number of meshing teeth between the driving wheel and the crawler is increased.At the same time,a coal retaining device is designed between the side of the driving mechanism of the roadheader and the driving gear teeth,which effectively controls the slime entering the meshing position of the driving wheel and the crawler and can timely discharge the slime between the driving gear teeth.It has improved the running stability of roadheader walking mechanism,reduced the number of slips per month,reduced equipment operation and maintenance personnel,and created more economic benefits for coal enterprises.
