摘要

油气润滑已被证明对高速轴承非常有效，因为液滴形式的油供应可以精确控制。本文采用光学干涉法研究了滚动点接触油滴润滑时润滑膜的形成机理。双油滴对的影响，其中两个油滴定位在围绕润滑轨道的中心轴的镜像，被检查。分析了油滴对接近和润滑轴承接触的过程。该研究还涵盖了以定制或随机分散模式提供的多个油滴的影响。此外，还研究了油粘度、夹带速度和液滴分布对饥饿的影响。

Effect of Oil Dispersion on Lubricating Film Thickness Generation under Oil Droplet Supply Conditions

Oil–air lubrication has proven to be very effective for high-speed bearings because the oil supply in the form of droplets can be precisely controlled. This work uses optical interferometry to study the mechanism of lubricating film formation in rolling point contact with oil droplet lubrication. The effect of a double oil drop pair, where two oil droplets are positioned in mirror images about the central axis of the lubricated track, is examined. The process by which pairs of oil droplets approach and lubricate a bearing contact is analysed. This study also covers the effect of multiple oil droplets supplied in a tailored or a random dispersion pattern. Additionally, the effects of oil viscosity, entrainment velocity, and droplet distribution on starvation are also investigated.
