摘　　要：辊式矫直是改善板型、消除残余应力、获得合格金属板带材的重要工艺环节,其工艺水平直接决定产品品质。在矫直设备组成中,矫直驱动系统作为矫直过程中变形能的来源,对矫直设备的设计和矫直工艺的制定有较大影响。通过试验研究,对矫直驱动系统的实际受载和理论计算值进行对照分析。研究表明,矫直咬入阶段的冲击载荷是矫直辊接轴损坏的主要原因,单根矫直辊扭矩试验值是理论计算值的近4倍;同时在矫直过程中,由于集中传动的影响,试验驱动扭矩分布与理论计算存在较大的不同。其中,3、4号矫直辊承担了弯曲变形大部分的驱动功。Because roller levelling can remove the flatness defects and induce the residual stress, it is an important step to get qualified plate and sheet. In the levelling parts, the levelling drive system is the deformation energy sources in the levelling process, and presses greater impact on the equipment design and process model. The ex- perimental of characteristics of drive for roller leveling was investigated. The result shows that the biting load is the main reason for roller spindle damage; the fact load is nearly four times as theoretical value. In same time, the result shows that there is a larger inconsistency of the drive toque distribution between the fact load and the theo- retical calculation.
