Beschreibung
Zusammenfassung:	An assembly for a gas turbine includes a hollow central shaft which is guided in rotation by at least one bearing, the assembly further including a device for lubricating said at least one bearing, the device including a hollow lubricant delivery tube which is arranged fixedly in the central shaft and is configured to deliver lubricant to the at least one bearing, the lubricant delivery tube having a first section with a first diameter and a second section with a second diameter which is greater than the first diameter, the second section including a plurality of radial channels connecting the inside of the lubricant delivery tube and leading radially to the outside of the lubricant delivery tube towards a radially inner wall of the central shaft so as to form a lubricant film between said second section of the lubricant delivery tube and said radially inner wall of the central shaft.
