Arrangement for mounting of a planet gear of a planetary gear

The invention relates to an arrangement for mounting a planet gear of a planetary gear (1) by means of at least one rolling bearing (2), wherein the outer ring (3) of the at least one roller bearing (2) in a bore (4) is inserted in the planetary gear (1). In order to realize a stress-free mounting of a planet wheel in a planetary gear, the bearing assembly according to the invention characterized in that on the outer circumference of the outer ring (3) or of the outer rings and / or in the bore (4) of the planetary gear (1) at least one helically extending groove (5 ', 5' ') is incorporated, at least two axial sections (6, 7) on the outer ring (3) or of the outer rings and / or at the machine part (1) are present, in which the groove (5', 5 '') extending in opposite directions.
