以某轧机径向调整用曲柄滑块机构为对象,研究该调整机构中传动副机械间隙对轧辊辊缝波动的影响情况。研究过程中首先利用矢量法建立曲柄滑块机构滑块运动和轧辊中心距之间的函数关系,然后把径向调整机构中因为安装误差、磨损产生的间隙转化为曲柄滑块机构中相应杆长的变化,最后找出机械间隙与轧机辊缝波动的关系,并得出一些有用结论。 With the adjustment of the radial direction of a rolling mill, the influence of the mechanical clearance on the roll gap of the roll was studied. In the course of the research, the relationship between the slider movement and the center distance of the roll was established by vector method firstly, and then the gap caused by the installation error and wear in the radial adjustment mechanism was transformed into the corresponding rod length in the crank-slider mechanism Finally, the relationship between the mechanical gap and the roll gap of the rolling mill was found, and some useful conclusions were drawn.
