【正文】 ment requirement higher,and investment cost is for in thin coal seam development meet the high general machine of coal mining is very machine of model of coal mining only aim at in thin coal seam meet the high general design and that goes on. The section of the machine of model of coal mining cut department mechanical transmission from 3 level directly tooth transmission and a level pla machine transmission realization,and end level adopts the pla transmission of the floating form of sun to rocker arm configuration with the coal space of increase cylinder and then raising pack coal efficiency。 Key words : Shearer 。 Pla anization III 目 錄 摘 要 .....................................................................................................................
