冶炼中用于脱模机上的重载差动螺旋传动是在高温、重载条件下工作，使用寿命较低，造成直接、间接的经济损失较大。由于对重载差动螺旋使用寿命的影响是多方面的，包括：载荷、温度、润滑、工况、螺旋副材料等。因此我们用有限元法分析了螺旋副的载荷分布；对重载差动螺旋失效机理进行了分析并做了模拟实验、磨损率试验；对润滑剂及螺旋副材料在相应的工况下进行了优化选用。根据大量的实验结果，提出较为适用的该螺旋传动的材料和润滑剂。

in steelmaking differential power screw drive are of ten used in drawing pattern machines.Power screw is under the condition of high t emperature and heavy loads.Adhesive wear,abrasive wear and multimode wear result in short life of drivers and increase economical losses. 　　Because load,temperature,lubrication,working conditions,materials of the screw p a ir,etc.all of them affect the life of power screw,so we must make the failure an alyses of drive equipment.Following methods are used in our work:(1)analyzing of the load distribution of screw pair by finite element method;(2)analyzing and t esting of wear mechanism;(3)simulating precipice of screw drive and testing of w ear rate;(4)optimizing of the lubricants and the screw materials for working con dition.Depending on a lot of test results,we suggested more suitable matenrials for the wear pair and lubricants.This can make the life of the differential powe r screw increase then before.
