Influencing Factors of Wear Stress Distribution of Pick-sShaped Interceptor Teeth of Cantilever Type Roadheading Machine
In order to further investigate the wear problem of pick-type interceptor of cantilever type roadheader,a pick-type interceptor is taken as a research case,and the effects of the cusp angle,cutting speed and cutting depth on the stress distribution are investigated from the perspective of stress distribution,and the optimal parameter combinations of the pick-type interceptor are determined to be the cusp angle of 75 °,the cutting speed of 2.0 m/s,and the cutting depth of 30 mm,based on which the optimized pick-type interceptor parameter combination is applied in practice.On this basis,the optimised parameter combination of pick-type cut-off teeth is applied in practice,and the results show that the life span of cut-off teeth is significantly improved,which proves that the wear problem of cut-off teeth has been effectively improved,and indicates that this study is of certain practical significance.
