Abstract
A lubrication system comprises a lubricant feed tank, a lubricant feed pump, one or more lubricant nozzles, a scavenge pump drive motor, and one or more scavenge pumps. The lubricant feed pump takes suction from the lubricant feed tank and pumps a lubricant feed as lubricant jets exiting the one or more lubricant nozzles. The lubricant feed pump has a rotating feed pump shaft coupled to a power source. The scavenge pump drive motor drives a rotating scavenge pump shaft that is coupled to the one or more scavenge pumps. The scavenge pumps return lubricant to the lubricant feed tank. The feed pump shaft and scavenge pump shaft rotate independently of each other.
