Abstract
The cooling effects of the lubricating oil supplied to a full journal bearing through two axial feed grooves each at right angles to the load line are studied. The thermohydrodynamic analysis assumes no heat is removed through either the journal or bush. The results show that the oil temperature distribution along the axial direction of the bearing is usually not uniform. Only if the axial length of the feed grooves approaches the bearing length will the temperature in the high pressure zone be uniformly distributed over its axial length. Both the oil supply pressure and the geometry of the feed grooves control the oil supply rate, which determines the cooling effect of the supply oil. Finally, a formula is suggested for the rate of supply flow. © 1987.
