beef什么意思Absrtact ： Due to the long u time of coal machine, there will be wear and aging and looning of counterpart parts during the u period, and even the phenomenon of moving part out of groove, which riously affects the production capacity of working face. In this regard, a dovetail locking device for coal machine parts was developed, which can greatly enhance the stability of coal machine parts connection, not only reduce the frequency of coal machine parts connection bolt looness and mechanical accident rate, but also reduce the labor intensity of field operators to maintain and repair the coal machine, and improve the productivity of the working face.
Key words ： coal machine; counterpart parts loo; dovetail locking
