通过分析螺栓连接受力机理,确定起重机械中使用高强度螺栓连接副的场所,阐明起重机械选用高强度螺栓连接副的标准;进一步从估算拧紧力矩、处理连接摩擦面和安装步骤三个方面指导安装高强度螺栓连接副;最后经过与普通螺栓连接副以及非起重机械用高强度螺栓连接副的比较,得出如何快速检验起重机械用高强度螺栓连接副。
By analyzing the mechanism of bolt connection force, the place of using high-strength bolt connection in lifting machinery is determined, and the standard of selecting high strength bolt connection for lifting machinery is clarified. From the further estimation of tightening torque, the connection friction surface and the installation steps are processed As a guide to install high-strength bolt connection; Finally, with the ordinary bolt connection, as well as non-lifting machinery with high-strength bolt connection deputy, come to how to quickly verify the crane with high strength bolt connection.
