轧机中心距调整机构由曲柄滑块机构构成,由于加工误差、装配误差、磨损等原因,调整机构中各构件的连接部分存在间隙。当通过曲柄滑块机构对轧机中心距进行调整时,由于间隙的存在,当采用两种不同的调整方式时,各构件在间隙位置的接触位置不同,会出现不同的调整结果。通过理论分析以及虚拟样机仿真,对上述两种调整过程进行对比分析。 The adjustment mechanism of the center distance of the rolling mill consists of a crank-slider mechanism. Due to machining errors, assembly errors, wear and other reasons, there is a gap in the connection part of each component in the adjustment mechanism. When the center distance of the rolling mill is adjusted by means of the crank-slider mechanism, different adjusting positions may occur when the contact positions of the members are different at the gap position when two different adjustment methods are adopted due to the existence of the gap. Through theoretical analysis and virtual prototype simulation, the two adjustment processes are compared and analyzed.
