Coal industry is the important basis of economic construction in China. Boring machine is applied in tunnel construction and mechanized Drivage of coal roadway is a kind of important mechanical equipment and working mechanism of cantilever directly involved in cutting working mechanism, broken period cutting performance on the overall work efficiency, reliability and service life, and the cutting of the economic benefits have direct influence, is a comprehensive reflection of the whole. In this design, the tunneling machine is a driving machine that can achieve continuous cutting, loading, transportation.. Cantilever roadheader consisting mainly of institutions, in accordance with the cantilever overall, power part, transmission part and part of the implementation of the design ideas of cantilever roadheader design. In the design, the power part of the selection calculation, the transmission part of the cutting reducer to do the specific calculation and verification. The subject I designed is the mechanism design for the cantilever working in the tunneling machine, and the design of the cutting mechanism.. To enhance and improve the working performance of the boring machine, the development of Chinas large - diameter full face tunnel boring machine industry and further improve our shield ability of research and development, improve the R amp; D conditions is
