| 20110018208 | ROTARY OIL FEEDTHROUGH - A rotary oil feedthrough is provided for sealing off a pressurized oil compartment between a rotatable shaft and a shaft mount, where the rotary oil feedthrough displays a radial oil passage for connecting an oil duct of the shaft and/or the mount to the pressurized oil compartment in fluid-permeable fashion, and has a seal arrangement that seals off the pressurized oil compartment on both sides in the axial direction of the shaft. The rotary oil feedthrough displays a sealing ring carrier that can be fastened to the shaft or the mount in non-rotating and fluid-tight fashion, the sealing ring carrier being arranged coaxially to the shaft or the mount, and an adapter that can be positioned on the other component of shaft and mount in fluid-tight fashion, and is surrounded laterally by the sealing ring carrier in the axial direction of the shaft. Located between sealing ring carrier and adapter are two axially separated sealing rings that each lie on the sealing ring carrier and the adapter in sealing fashion in order to seal off the pressurized oil compartment in the axial direction of the shaft, and that can be rotated relative to the sealing ring carrier and/or the adapter. The rotary oil feedthrough displays the longest possible service life, the minimum possible leakage, and good response characteristics, and is of simple structural design. | 01-27-2011 |
