Claims

[Claims for Utility Model Registration] 1. An oil tank having an upper oil sump above a bearing support and a lower oil sump below, a rotating plate that is attached to a rotary chamber shaft and rotates within the lower oil sump, and this rotating plate. Rotation of a chamber shaft type bearing device having an oil pumping hole provided in the upper surface of the shaft, which takes in lubricating oil from the upper surface inlet and releases it to the outside by centrifugal force, and an oil pumping passage that supplies the lubricating oil from the oil pumping hole to the upper oil reservoir. In the oil lifting device, a partition plate is provided on the entire circumference or a part of the lower oil sump and partitions the area from near the outer wall of the lower oil sump to near the entrance of the oil lifting hole into upper and lower parts, and the rotating chamber shaft 2. A rotary oil pumping device for a chamber shaft type bearing device, characterized in that, during rotation of the chamber shaft type bearing device, lubricating oil near the outer wall in the lower oil reservoir is supplied to the oil pumping hole through the upper surface of the partition plate. 2. A rotary oil pumping device using a chamber shaft type bearing device according to claim 1, wherein the partition plate is an annular plate extending over the entire circumference of the lower oil reservoir. 3. A rotary oil lifting device using a chamber shaft type bearing device according to claim 1 or 2 of the utility model registration, wherein the partition plate is inclined downward as it goes inward.
