A Method of Assembling Clearance Measuring of Oil Film Bearing in Tandem Cold Mill

Abstract

AbstractIn order to reduce the certain number of oil film bearing burning accident, this paper proposes a novel method used to test static pressure pipes and measure the assembling clearance between sleeve and bush inside the bearing. On account of the theory of lubrication and the working mechanism for oil film bearing, through the development of a new set of hydrostatic oil supply system and test platform, provide the static supporting pressure and the disassembling and locking pressure. And based on this method, the assembling clearance measuring was carried out. The results show that the proposed measuring method has the ability to support the disassembling and assembling process of the oil film bearing. In addition, this method provides an important basis for the engineers of cold rolling mill on site to adjust the assembling clearance of oil film bearing. The application of this method effectively reduces the online burning accidents of the oil film bearing.
