  • Fluted insert for lubrication systems in power transmission devices
    Patent number: 5341901
    Abstract: 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.
