摘　　要：针对榆钢高线摩根五代吐丝机轴承一直存在使用振动高寿命短的问题,榆钢公司结合目前高速线材吐丝机设备的前沿发展,以及油膜轴承技术在轧钢高速区设备的普遍应用。将油膜轴承替代传统的滚动体轴承新技术引入到吐丝机设备中,改变传统的两盘圆柱滚动体轴承支撑空心轴结构,采用整体形式油膜轴承+滚动体轴承结构进行替代。既保留了滚动体轴承转动初始阶段的空心轴支撑,又保留了高速状态时吐丝机的旋转浮力支撑。解决了高速旋转时的刚度需求和空心轴的稳定性。大大解决了吐丝机振动高寿面短的问题。本文详细叙述了榆钢高线生产线吐丝机技术改造问题及解决方法,阐述了油膜轴承的优劣,改造后设备故障大幅度降低,彻底解决了因为吐丝机轴承故障造巨大的经济损失和严重的设备隐患。In view of the problem of short service life and high vibration of the bearings of Morgan’s fifth generation wire spinner for high-speed wire rod of Yugang,Yugang Company has combined the cutting-edge development of high-speed wire rod wire spinner equipment at present,as well as the widespread application of oil film bearing technology in high-speed rolling equipment.The new technology of replacing the traditional rolling element bearing with oil film bearing is introduced into the wire spinner equipment.The traditional structure of hollow shaft supported by two disk cylindrical rolling element bearing is changed,and the integral oil film bearing+rolling element bearing structure is adopted for replacement.The utility model not only retains the hollow shaft support at the initial stage of the rolling element bearing rotation,but also retains the rotary buoyancy support of the spinning machine at high speed.It solves the stiffness requirement and the stability of hollow shaft when rotating at high speed.The utility model greatly solves the problem of high vibration and short service life of the spinning machine.This paper describes in detail the technical transformation problems and solutions of the wire spinner in the high-speed wire production line of Yu Steel,expounds the advantages and disadvantages of the oil film bearing.After the transformation,the equipment failure is greatly reduced,and completely solves the huge economic losses and serious equipment hidden dangers caused by the bearing failure of the wire spinner.
