Abstract (en)

[origin: WO2022058085A1] The invention relates to a method for mounting a rotor (12) of an electrical machine on a gearbox (11) of an electric drive unit (10) and to an electric drive unit (10) for a vehicle, wherein the rotor (12) comprises a rotor shaft (14) having a holding portion (16) for holding an input pinion (18), the method comprising the steps of: - providing at least one sealing element (20) and at least one rolling bearing (22); - feeding the rotor shaft (14) through the sealing element (20) and through the rolling bearing (22) such that the holding portion (16) extends into the gearbox (11); - mounting the input pinion (18) on the holding portion (16) of the rotor shaft (14); and - joining the input pinion (18) to the rotor shaft (14) by means of a welding process.
