Plain bearing, and method for lubricating and cooling a plain bearing

A plain bearing of a planetary gearbox has first and second rotationally connected components. Oil adjacent an oil feed pocket of the first component is directed into the bearing clearance between the components by a first line that opens into the pocket. The line includes a first portion and a down...

Beschreibung
Zusammenfassung:	A plain bearing of a planetary gearbox has first and second rotationally connected components. Oil adjacent an oil feed pocket of the first component is directed into the bearing clearance between the components by a first line that opens into the pocket. The line includes a first portion and a downstream second portion. The flow cross section of the first portion is smaller than the flow cross section of the second portion. The flow cross section for the oil, in the feed direction, in the circumferential direction of the clearance and in the main rotation direction of the second component relative to the first component increases more than counter to the main rotation direction of the second component, or in the circumferential direction of the clearance and counter to the main rotation direction of the second component increases more than in the main rotation direction of the second component.
