内容简介：

摘 要采煤机是综采技术的主要组成部分，随着综采技术在煤炭工业上的应用，采煤机的发展也得到了加快。截割部落煤的装置是采煤机重要组成部分之一。它的功率消耗占采煤机装机功率的80%90%。工作机构的截割性能好坏，减速器传动质量的好坏直接影响采煤机的生产率、传动效率、比能耗和使用寿命。生产率高和比能耗低主要体现在截割部。 在参考国内外有关薄煤层采煤机的情况下，完成了薄煤层双滚筒式采煤机传动系统的设计。第一部分介绍了采煤机国内外的发展概况，基本结构、性能及工作原理。第二部分通过直齿传动方案的设计以及计算，直齿传动从电机出发，经锥齿轮减速，再到三级的直齿减速，将动力传递给滚筒。关键词：薄煤层；滚筒；采煤机；直齿Abstract Shearer is fully mechanized mining technology a major component, with the mechanized mining technology in the coal industry, the development of Shearer has also been accelerated. Cutting tribe coal shearer important means is one of the components. Its power consumption accounted for 80% to 90% of installed power shearer. Cut working bodies of cutting performance is good or bad, reducer transmission quality directly affect productivity, drive efficiency shearer, specific energy consumption and service life. High productivity and low specific energy consumption is mainly reflected in the cutting unit. In reference to domestic and foreign thin seam Shearer, the completion of the thin seam double shearer loader drive system design. The first part introduces the development of shearer home and abroad, the basic structure, performance and works. The second part of the program through direct gear drive design and calculation of spur gear from the motor, via bevel gear, straight teeth and then three of deceleration, power is tran
