OSTI ID:5755200
A continuous mining machine includes a body portion mounted on endless tracks and a boom member extending forwardly from the body portion with a cutter drum member rotatably mounted on the front end of the boom member. The cutter drum member has an intermediate drum section and a pair of end drum sections. A pair of driven input shafts are drivingly connected to the pair of end drum sections respectively. Intermediate drive shafts extend from the end drum sections into the ends of the intermediate drum section. The intermediate drum section is formed by a pair of releasably connected housing sections. A connecting plate is positioned within and nonrotatably secured to each housing section. Each connecting plate includes planar faces that engage corresponding planar faces provided on the end of the respective intermediate drive shaft. With the intermediate drum sections assembled on the drive shafts, the connecting plates are nonrotatably connected to the drive shafts to transmit rotation from the drive shafts to the housing sections to rotate the intermediate drum section. Pairs of connecting plates are releasably connected to one another surrounding the drive shafts to facilitate efficient assembly and disassembly of the intermediate drum section.
