Claims

[Scope of utility model registration request]

an oil tank having an upper oil sump above the bearing support and a lower oil sump below; an annular recess provided on the bottom of the lower oil sump of the oil tank and concentric with the rotary chamber shaft; a rotating plate that rotates within the recess; an oil lifting hole provided in the rotating plate having an upper surface inlet and an outer peripheral surface outlet; lubricating oil released from the outlet of the oil lifting hole by centrifugal force to the outside of the recess; In a rotary oil pumping device of a chamber shaft type bearing device having a pumping oil passage supplying oil to the upper oil sump from an inlet opening on a side surface, the rotary oil pumping device is provided on the bottom wall of the oil tank and opens on the bottom surface near the outer wall of the lower oil sump. an oil return hole having an inlet opening to the outer surface of the recess and an outlet opening to the outer surface of the recess, the lubricating oil in the lower oil reservoir near the outer wall passing through the oil return hole when the rotary chamber shaft rotates. A rotary oil lifting device using a chamber shaft type bearing device, characterized in that the oil is returned to the periphery of the rotary plate.
