Abstract
In this report, the operating characteristics and the mechanism of lubrication of high speed tapered roller bearing under lubrication by atomized oil are investigated experimentally and theoretically. As the experimental results about the influence of oil consumption, air consumption, viscosity of oil, load and rotating speed, it has been clarified that the lubrication by atomized oil lessens the friction remarkably and the temperature rise in the suitable condition and the atomized oil lubricates mostly as hydrodynamical lubrication. According to the above mentioned character, the hydrodynamical theory concerning the friction moment and temperature rise of tapered roller bearing has been deduced, and it is confirmed that this theory coincides with the results of experiments moderately well.
