• or
• (ii) a second adapter including a second adapter shaft rotationally fixed or integral to the driving toothing part, a first bearing identical to the first bearing of the first adapter, and a second housing having a first housing part identical to the first housing part of the first adapter, a second housing part identical to the second housing part of the first adapter, and an intermediate flange, the first housing part of the second adapter being connected to the intermediate flange, the intermediate flange being connected on a side thereof facing away from the first housing part of the second adapter to the second housing part of the second adapter, an inner ring of the first bearing of the second adapter being arranged on the second adapter shaft, an outer ring of the first bearing of the second adapter being accommodated in the first housing part of the second adapter and in the intermediate flange and centering the first housing part of the second adapter with respect to the intermediate flange, a shaft seal ring or a freewheel being accommodated in the intermediate flange or integrated in the intermediate flange;
• and
• an electric motor;
• wherein a rotor shaft is rotationally fixed to a clutch part;
• and
• wherein a stepped key connects the rotor shaft to the clutch part in a form-fitting and/or rotationally fixed manner in a circumferential direction, the stepped key including an outer collar projecting radially outwards that delimits the clutch part in an axial direction, the stepped key including an inner collar projecting radially inwards set against an end face of the rotor shaft and/or delimiting the rotor shaft counter to the axial direction, a region covered by the stepped key in the axial direction overlapping with a region covered by the clutch part in the axial direction and overlapping with a region covered by the rotor shaft in the axial direction and/or overlapping with a region covered by the adapter shaft in the axial direction, the rotor shaft including a keyway adapted to accommodate the stepped key, the keyway being stepped such that the inner collar is accommodated in the keyway and/or such that the inner collar is flush with the end face of the rotor shaft.

A geared motor, comprising

• an adapter having an adapter shaft, a first bearing, a first housing part, dogs, and a clutch part;
• an electric motor having a second housing part;
• and
• a transmission;
• wherein the first housing part is connected and/or directly connected to the second housing part;
• wherein an inner ring of the first bearing is arranged on a bearing seat of the adapter shaft;
• wherein an outer ring of the first bearing is accommodated in the first housing part and second housing part and centers the first housing part with respect to the second housing part;
• wherein the bearing seat covers, in an axial direction, a first region in which the bearing seat is uninterrupted in a circumferential direction, and a second region in which the bearing seat is interrupted in the circumferential direction;
• wherein a rotor shaft is rotationally fixed to the clutch part;
• and
• wherein the adapter shaft is rotationally fixed and/or integral to a driving toothing part of the transmission;
• and
• wherein a stepped key connects the rotor shaft to the clutch part in a rotationally fixed manner in the circumferential direction, the stepped key including an outer collar projecting radially outwards delimiting the clutch part in the axial direction, the stepped key including an inner collar projecting radially inwards set against an end face of the rotor shaft, a region covered by the stepped key in the axial direction overlapping with a region covered by the clutch part in the axial direction and overlapping with a region covered by the rotor shaft in the axial direction and/or overlapping with a region covered by the adapter shaft in the axial direction, the rotor shaft including a keyway adapted to accommodate the stepped key, the keyway being stepped such that the inner collar is accommodated in the keyway.
