Planetary gear box and method for operating a planetary gear box and gas turbine engine having at least two central shafts and having a planetary gear box

A planetary gearbox of a gas turbine engine has a planet gear which, via a bearing, is arranged rotatably on a planet pin of a rotatable planet carrier. Oil is introduced through an opening, arranged radially within the bearing, into an oil feed which is open at a feed side and which is connected to...

Beschreibung
Zusammenfassung:	A planetary gearbox of a gas turbine engine has a planet gear which, via a bearing, is arranged rotatably on a planet pin of a rotatable planet carrier. Oil is introduced through an opening, arranged radially within the bearing, into an oil feed which is open at a feed side and which is connected to the bearing and rotationally joined to the carrier. As the carrier rotates, the oil downstream of the opening is conducted toward the bearing unit by centrifugal force. The open oil feed is, between the opening and the bearing, configured an oil filter through which the oil is conducted. The filter extends counter to the flow direction of the oil from the opening in the direction of the bearing unit, in a flow direction of the oil in the open oil feed.
