摘要
分析了航空燃气涡轮发动机主轴承产生滑蹭损伤的机理与危害。并根据滑蹭损伤的机理,提出了防止轴承出现滑蹭损伤的两项措施:增加驱使滚子-保持架运动的拖动力;减小阻碍滚子-保持架运动的阻力。列举了国外一些发动机中防止滑蹭损伤采用的措施。
The mechanism and impact of aero-engine bearing's skidding damage are analyzed. Two ways to prevent bearing from skidding damage are discussed. They are to make the roller-retainer keep moving by increase pulling force and to reduce its resistance. Some preventive measures of skidding damage used on foreign aero-engines are listed.
