摘　　要：以5号张力辊为例,对张力辊的主要技术参数辊子直径、带钢包角与辊子偏心距的关系进行了分析计算,进而推导出了欧拉公式;以此为基础,对张力放大系数和辊子传动电机功率进行了验算。验算结果表明,张力辊的设计是合理的。通过设计分析计算,可以有效维修设备、降低设备故障、提高机组稳定运行,为同类机组的设计提供参考。Taking No.5 bridle rolls as an example, this article analyzes and calculates main technique parameter of roller diameter in bridle rolls and formulations about the steel strip＇s wrap angle and offset distance of roll eccentricity,deduces the Euler＇s formula.Based on Euler＇s formula,tension magnify coefficient and drive motor power for each bridle roll are checked.The check computations indicate bridle roller design is reasonable. CAL Bridle rolls equipment layout format of VAI design..The design analysis calculation effectively repairs equipment, reduces equipment failure and improves stable operation of the units,provides references for the design and calculation of the bridle roll units in other analogical equipments.
