Abstract:
A hollow cylindrical rotary bearing shaft for a planet gear of an epicyclic gear train, has a cylindrical outer surface accommodating the planet gear, and a wall thickness. The wall thickness of the bearing shaft varies circumferentially around a diameter of the bearing shaft so as to produce a pre-determined circumferential variation in the wall thickness.
