ABSTRACT:
A pressurized lubrication system for a rotatable power shaft of a power transmission device includes a pump which is mounted on the housing of the power transmission device. The pump has a drive shaft which is coaxially aligned with the power shaft and coupled to a free end thereof so that the pump will be operated by rotation of the power shaft. The pump takes in suction from the oil sump and discharges lubricating oil under pressure to a region of the housing which is defined shaft sealing to enclose the free end of the power shaft therein. Lubricating oil is delivered through a central bore in the power shaft which has an opened end at the free end of the power shaft to be then transmitted through radial passages to various elements which are mounted on the power shaft for independent relative rotation.
