Patent ID: 8241172

Claim:
An arrangement in a planetary gearing where the arrangement includes: a planet gear including at least three planet wheels each of the planet wheels having an inner race, at least one bearing supporting it, and further a shaft supporting this bearing, a carrier for the planet gear including a first flange connected to an input shaft and a second flange on the opposite side, and each shaft of the planet wheel has a first end with diameter D 1 non-rotatably adapted to said first flange over a first support length, a center area thicker than the first end for supporting the bearing, a second end non-rotatably adapted to said second flange over a second support length (g), and the arrangement further includes a construction allowing flexing in each shaft for dynamically adapting the mesh geometry of several planet wheels to the elasticity of the construction, characterized in that the construction allowing flexing of the shaft is a flexing interval (a) having the diameter D 1 of the said first end and a gentle rounding protruding from the diameter D 1 of the said first end towards the diameter D of the thicker center area, and the said flexing interval (a) is between the first support length (f) and the thicker center area and particularly outside the center area.
