摘要
为了实现叶片辊轧机轧辊位置的精确调整,建立了包含蜗轮蜗杆、滚珠丝杆、斜板等零部件刚度影响下的运动误差方程,研究了传动机构刚度、轧辊初始安装预紧量对其运动精度的影响,并通过实验对仿真结果进行了分析,结果表明:当轧辊初始安装预紧量为0时,轧辊的运动精度受零部件传动刚度、轧辊移动阻力的影响较大,当预紧量大于0.04 mm时,轧辊的移动精度提高,但会加剧轧辊与斜铁之间的磨损,结合现场应用,确定0.04 mm是轧辊初始安装的最佳预紧量。
In order to achieve precise adjustment of roller displacement of blade rolling mill, transmission equations motion error of transmission components considering the stiffness of worm gear, silk pole, skew plate were established. Contact stiffness of transmission mechanism and the effect of initial preloading of roller on motion accuracy were researched. The simulation results were verified by experiment. The results show that： when initial installed preloading of roller is equal to 0 mm, transmission stiffness of components and shifting resistance have great influence on kinematic accuracy of roller, when initial installed preloading of roller is more than 0.04 mm. , kinematic accuracy of miler will be improved,but increaseing wear between roller and skew plate. Combined the engineering field, the best initial installed preloading is 0.04 mm.
