延绳钓鱼机失效原因分析

Failure Analysis of Long Line Fishing Machine

本文通过对某延绳钓鱼机在远洋钓鱼作业中失效原因进行分析,得出该钓鱼机主要零部件滚筒壁厚不足原设计值的50%,导致正常工作时,滚筒轴向伸长量增加,致使滚筒两侧的机械零件损坏,使该钓鱼机不能正常工作。并针对失效原因,对钓鱼机滚筒的设计生产提出一点建议。

The paper analyzed the failure reason of the long line fishing machine, the results indicated that the thickness of the roller which is the main component of the long line fishing machine is less than fifty percent of the design value, result in the extension of the roller increase at normal working conditions. Leading to fracture of the parts at the side of the roller and failure of the fishing machine, and according to the failure reason, the proposal was advanced about the design and manufacture of the roller.
