摘　　要：针对双面铣机组九辊矫直机频繁出现的齿轮轴折断现象,本文系统分析了矫直机的工作机制,并对矫直辊的弯曲变形进行了深入且全面的探究。在此基础上,本文对矫直机的主要参数进行了严谨的选定与计算,并对工作辊的弯曲变形进行了严格的校核分析。通过综合研究,本文揭示了齿轮轴折断的根本原因,并提出了生产使用中应重点关注的事项。本研究旨在为生产人员提供操作指导,以保障生产设备的稳定运行和高效性能。In response to the frequent occurrence of gear shaft breakage in the nine-roll straightener of the double-sided milling machine set,this paper systematically analyzes the working mechanism of the straightener and conducts an in-depth and comprehensive investigation into the bending deformation of the straightening rolls.On this basis,the paper rigorously selects and calculates the main parameters of the straightener,and performs a strict check analysis on the bending deformation of the working rolls.Through comprehensive research,this paper reveals the root causes of gear shaft breakage and proposes key points that should be focused on during production and use.The aim of this study is to provide operational guidance for production personnel to ensure the stable operation and efficient performance of production equipment.
