METHOD AND APPARATUS FOR ADJUSTING LUBRICANT TEMPERATURE WITHIN A GEARBOX

摘要

A lubrication system (50) adapted for use in a mechanical gearbox (24) that includes multiple gear meshes and bearing locations. The lubrication system (50) includes multiple heat exchangers (51, 52) that are suitable to tailor the temperature of the lubricant to a predetermined value for the gear meshes and bearing locations. In one form a first heat exchanger (52) adjusts the temperature of a quantity of the lubricant to a first predetermined value and a second heat exchanger (51) adjusts the temperature of a quantity of the lubricant to a second predetermined value. The lubricant after exiting the respective heat exchanger at the first predetermined value and/or the second predetermined value is delivered to the respective bearing or gear mesh to lubricate and cool the component.
