摘要
采用超声振动原理建立了一台汽车发动机滑动轴承模拟气蚀试验装置。试验研究了空气混入滑动轴承后对其气蚀磨损的影响。通过大量试验研究结果的分析比较 ,发现空气的混入会使滑动轴承的气蚀磨损降低 ,且含气率越高这种影响作用越明显。
A experimental device for cavitation erosion is established by use of the mechanism of ultrasonic vibration. The influences of bubbly oil on the cavitation erosion in journal bearings in engines are investigated in detail. From analyzing these experimental results it is found that the bubbly oil decrease the cavitation erosion in engines, and the more the bubble content is, the more the influence is. The traditional mechanism of gaseous cavitation erosion is discussed and explained in a new way according to the experimental results.
