一、前言近来,冷轧钢板质量的要求越来越严格,故保证板厚是必要的。虽然在连轧机上采用液压压下,能够提高轧机的刚性;但因辊子偏心,尤其在油膜滑动轴承中,将发生复杂的压力波动,对板厚影响甚大。靠普通的辊子偏心消除装置是难以实现的。为尽量减少辊子偏心的影响,从实际和理论方面来分析轧制力的变化,研制了新型的油膜轴承(无键轴承)。 First, the preface Recently, the quality of cold-rolled steel more stringent requirements, it is necessary to ensure the thickness of the plate. Although the use of hydraulic rolling in the continuous rolling mill, can improve the rigidity of the mill; However, due to roller eccentricity, especially in the oil film sliding bearings, complex pressure fluctuations will occur, a great impact on the thickness. By ordinary roller eccentric elimination device is difficult to achieve. In order to minimize the influence of roller eccentricity, the change of rolling force is analyzed from the practical and theoretical aspects, and a new type of oil film bearing (keyless bearing) is developed.
