MP_2-100型极薄煤层采煤机是煤炭科学研究院重庆研究所和无锡采煤机械厂承担的国家“六五”期间攻关项目,该机于1986年12月正式定型,批量生产,推广使用。它是我国第一台通过1000小时耐久试验的薄煤层采煤机。在研制中,改进截割部重载传动Ⅱ轴的经验,为今后采煤机重载轴类零件的设计制造提供了很好的借鉴。 一、Ⅱ轴酌设计和强度核算 MP_2-100型采煤机是用于0.6～0.8米极薄煤层中爬底板割煤的固定滚筒采煤机,它的截割部是一个矩形减速箱。为了缩短机身
MP_2-100 type ultra-thin coal seam shearer is the research project undertaken by Chongqing Research Institute of Coal Science Research Institute and Wuxi Mining Machinery Plant during the “Sixth Five-Year Plan” period. This machine was officially finalized in December 1986 and was mass-produced and popularized . It is the first thin coal seam shearer in China to pass 1,000 hours of durability test. In the course of development, the experience of improving the II axis of heavy-load transmission in the cutting department is provided as a good reference for the design and manufacture of heavy-duty shaft-type parts of shearer in the future. A, Ⅱ axis discretion design and strength calculation MP_2-100 type shearer is used in the 0.6 ~ 0.8 m thick thin seam coal miner crawling fixed drum shearer, the cutting unit is a rectangular gear box. In order to shorten the fuselage
