In order to optimize the variable speed transmission control effect of mining processing machinery,improve the transmission efficiency of processing machinery,and make the variable speed transmission control meet the needs of large mining engineering,the research on the variable speed transmission control method of large mine processing machinery is carried out.First,according to the working situation of the processing machinery,determine its variable speed transmission ratio range.Secondly,within the range of the transmission ratio,the variable speed transmission parameters of the processing machinery are calculated.Based on the mode switching control strategy,the continuous conversion control of variable speed transmission of processing machinery is carried out.The experimental analysis results show that after the application of the proposed variable transmission control method,under the increase of speed ratio,the transmission efficiency of processing machinery variable speed increases greatly,and the transmission efficiency is always higher than the control group,which has high feasibility and variable transmission control effect.
