Abstract: The invention relates to an arrangement in a planetary gearing (10) comprising a rotatable shaft (11) connected to the planet wheel carrier (13) of planet wheels (14a), an internal gear (15) and a sun wheel (16), wherein the planet wheels (14a) operatively engage by their coggings (14?), i.e. mesh, with the outermost fixed-position cogging (15?) of the internal gear (15) and with the centrally located cogging (16?) of the sun wheel (16). The power is transmitted from the sun wheel (16) to the input shaft (33) of the following stage (30) by means of a coupling permitting radial and/or angular deflection. The lubrication system includes a connection (20) permitting rotation and said deflection between the frame (8) and the planet wheel carrier (13).
