摘要
介绍了悬臂式重型掘进机的使用工况,分析了某悬臂式重型岩巷掘进机截割悬臂与机器本体联接处的螺栓受力情况,通过部分系数法完成联接螺栓的选型设计。对类似的螺栓联接设计有一定的参考作用。
The condition of heavy mine roadheader was introduced.The forces condition of the heavy mine roadheader and itself was analysed.Through partial coefficient method to finish the connection of the bolt＇s design.It has some functions to the similar connection design of bolt.
