水城钢铁(集团)公司第一轧钢厂准高线车间的精轧机组采用的是摩根三代45°侧交无扭轧机,锥箱轴承采用的是美国摩根公司进口的全套轴承,其中8/6″锥箱内的MR-126-KC10轴承(以下简称轴承A)和MR-7310PD7B(以下简称为轴承B)上机运转才9天就失效了,远远小于设计的轴承寿命。由于摩根轴承价格昂贵,所造成的损失大,因此急需对轴承的失效原因进行分析。主要从轴承的材料和理论负荷校核等方面对摩根轴承的失效原因进行了研究。
The first rolling mill in Shuicheng Iron & Steel (Group) Co., Ltd., the finishing mill of the quasi-high-speed workshop, adopted the three generations of 45 ° cross-section non-twisting mills. The cone box bearings adopt a full set of bearings imported by the United States Morgan Company, of which 8/6 " In the cone box MR-126-KC10 bearing (hereinafter referred to as the bearing A) and MR-7310PD7B (hereinafter referred to as the bearing B) on the machine running only nine days fails, far less than the design of the bearing life. , The damage caused by the large, so the urgent need to analyze the cause of the failure of the bearing.Mainly from the bearing material and theoretical load checking and other aspects of Morgan bearing failure causes were studied.
