Several key technical issues of lubricating and cooling for aeroengine mainshaft bearings were studied. The selection basis of lubricant was proposed and the characteristic of the oil feeding modes and the applied guideline of the oil feeding pressure were analyzed. The operation method of the computation formula for the oil flow in engineering design was presented and the focus on designing the nozzles and the lubrication structures were induced.
