内容简介：

摘 要MG180/435-W型液压牵引采煤机主要用于中厚煤层的综采作业。它可以一次采全高，并且能适应煤层厚度变化和底板起伏不平的条件。该采煤机适应性好、功率大、采煤效率高、操作简单、检修方便。本设计主要针对采煤机的整机进行方案设计，对截割部进行结构及传动等相关设计。MG180/435-W型液压牵引采煤机采用弯摇臂截割部，截割电机横向布置在摇臂上，摇臂和机身连接没有动力传递，取消了螺旋伞齿轮和结构复杂的通轴。在截割部传动设计中，利用直齿轮和行星齿轮组成减速器是设计的一般原理，设计出适合截割部使用的减速器，并将它和矿用电动机直接联结，简化了截割部的传动布置。本设计的创新点：把截割部的减速器安装在摇臂里，使用了两个惰轮来增加中心距，这样也使齿轮的总个数减少，提高了传动效率。结构上将离合器安装在电机轴上，使制动变的方便安全。设计中对2K()型行星减速器进行了优化配齿，采用高度变位，并做了相应的校核，在保证需要的传动比的情况下，使设计的2K()型行星减速器体积最小。关键词：采煤机 ；截割部 ；行星减速器 ；摇臂ABSTRACTThe MG180/435-W type liquid presses to lead to shearer to mainly used for the medium thick coal seam to adopt homework. It can cuts the whole seam height in one trip, and accommodate the changing of seam thickness and floor undulation. Should the shearer adaptability like, the power is big and adopt a coal efficiency high, operate in brief and check to fix convenience. This design mainly carrieson a project design to the whole machine of the shearer, spreading to move to wait a related design towards the cutting drum to carry on structure. The MG180/435-W type liquid presses to lead to shearer curved the ranging arm of the cutting drum, and the electrical engineering horizontal arranges in the ranging arm. There is no motive delivering between ranging arm and gearhead conjunction and canceling spiral umbrella wheel gear and structure a complicated stalk. In the design of the cutting drum spread move , the exploitation keeps the general theory that wheel gear and planet wheel gears constituting to decelerate a machine is a design. Designing to suit a deceleration machine which mows an usage, and will it and the mineral use electric motor to combine directly, simplifying to the cutting drum to spread to move a decoration. The creative of this design: Cut a deceleration machine of mowing the department to install in the ranging arm, used two round to increase center to be apart from, so as to make the total piece of wheel gear reduced, and raised to spread to move an efficiency. The structure full general clutch installs on the electrical engineering stalk, making the moving convenience and safety. In the Design medium to 2K() type the planet decelerated a machine to carry on excellent turn to go together with teeth, adopt height to change, and did a homologous check. Be promising to need of spread under circumstance of moving the ratio, make the 2K() of design type planet
