摘　　要：压下装置是短应力线轧机的重要组成部分,用于调整轧辊孔型。本文分析了不同压下装置的结构形式及其速比、传动效率等,结合典型的双螺母式拉杆结构,对压下装置所需的能力进行计算。双蜗轮式压下装置速比大,精度高,但效率较低;蜗轮-齿轮式压下装置的输出转向一致,配合拉杆只需一种。The screw down device is an important component of the short stress path rolling mill,it mainly used in adjusting the rolling grooves.This article analyzes the structure,speed ratio and transmission efficiency of different screw down devices.Combined with the typical double-nuts type tie rod structure,the required capacity of the screw down device is calculated.The double worm wheel screw-down device has large speed ratio,high precision,but low efficiency.The output diversion of the worm wheel-gear type screw-down device is consistent,and only one kind of tie rod is needed.
