摘　　要：由于轧辊弹性弯曲微尺度行为是否可控,直接影响轧机轴承和轴向调节螺纹机构的寿命,为此对KZ型高刚度轧机轧辊弯曲微尺度行为进行了理论分析和实验研究,并用自行开发的三维接触边界元轴承专用程序解析出KZ型轧机轴承和轴向调节螺纹载荷特性。结果表明,KZ型高刚度轧机具有空间自位性能,其轧机轴承和轴向调节螺纹机构载荷均载,轧辊弹性弯曲微尺度行为可控。Whether the micro-size action of the elastic deformation on roll is controllable, it directly affects the service life of mill roller bearings and axial adjust .screw mechanism. In this paper, the micro-size action of the elastic deformation on roll about KZ type high rigid mill is analyzed on theory and studied by experiment. In addition, by using three dimensional contact boundary element program, the peculiarity of load on roller bearing and axial adjust screw mechanism are obtained too. The studied result shows that KZ type high rigid mill has three dimensional selfaligning characteristic; the load on roller bearing and axial adjust screw mechanism is uniform; the micro-size action of the elastic deformation on roll can be controllable.
