The characteristics of the sudden-expansion pipe in oil-air lubrication system have been analyzed based on Fluent. The results show that the pressure and oil film mutate when the annular flow through the sudden-expansion pipe and the suddenly change of position of pressure and film is not affected by the inlet air velocity, however, the strength of ...

Study on Temperature Control Method of High Speed Ball Bearing with Oil-Air Lubrication
2017 4th International Conference on Information Science and Control Engineering (ICISCE), 2017For high speed ball bearing, the oil-air two phase flow calculation model is constructed based on twobody fluid model and turbulent model, in which oil-air two phase flow are considered. The numerical study reveals the relationship between bearing temperature rising and rotating speed, oil viscosity, radial clearance, preload, ratio of air phase ...

A Study on Oil/Air Lubrication and Preload of a High Frequency Fully Ceramic Motor Spindle
2010 International Conference on E-Product E-Service and E-Entertainment, 2010Trend of the high speed and high efficiency machining has pushed the continuous demand of higher spindle speed and power for the machining center application. However, the extremely high speed will produce significant centrifugal force. Conventional steel spindles are not appropriate for high speed operation because of their high rotational inertia and
