超级螺栓在采煤机摇臂上的应用

Application of Super Bolt in Shearer Ranging Arm

采煤机摇臂为了实现左右互换,一般设计为直摇臂搭配连接架。摇臂与连接架通过4根销轴联接,但这种方式受结构限制,连接架尺寸较大,摇臂整体长度较长,无法满足紧凑型产品的应用。随着摇臂壳体铸造材料的提升,利用超级螺栓直接紧固摇臂与连接架成为一种可能。介绍了超级螺栓的特点、使用方法及其在采煤机摇臂上的应用。

Shearer ranging arm in order to achieve left and right exchange, the general design for the straight ranging arm with a connection frame. Ranging arm and the connecting frame are connected by four pins, but this way is limited by the structure, the connecting frame is larger in size and the overall length of the ranging arm is longer than that of the compact product. With the ranging arm shell casting material to enhance the use of super-bolts directly to the ranging arm and connecting frame as a possible. Introduces the characteristics of super bolts, the use of methods and its application in the Shearer ranging arm.
