通过对 JK80 0 - 2型注水电机滚动轴承存在问题的分析研究 ,提出了将原滚动轴承改为油环轴承的改造方案 ,并设计了油环轴承 ,使其在额定转速为 2 980 r/ min,线速度为 14m/ s的 JK80 0 - 2型电机上正常运行。不仅为电机改造探索了一条途径 ,而且也为油环轴承使用范围的拓展、润滑机理的理论研究提供了实际依据。 Based on the analysis and study of the problems existing in JK80 0-2 water injection motor rolling bearing, a modification scheme of changing the original rolling bearing to the oil ring bearing is proposed and the oil ring bearing is designed so that it can rotate at the rated speed of 2 980 r / min, JK80 0-2 type motor running at 14m / s. Not only for the motor to explore a way to reform, but also for the expansion of the use of oil ring bearings, lubrication theory provides a theoretical basis for the study.
