Fluted insert for lubrication systems in power transmission devices

摘要

The present invention is directed to an improved lubrication system for power transfer devices which increases the flow of lubrication along an axial bore formed within a rotating shaft. In the present invention, a rotor is disposed within the bore of a rotating shaft and secured to rotate with the shaft. The rotor acts to draw substantially more lubrication along the bore than would be drawn due to the centrifugal effect alone.
