A geared motor, having a gear unit, an electric motor and an adapter flange arranged between the gear unit and the electric motor, wherein the adapter flange has an annular base body formed rotationally symmetrically to the axis of rotation of an input shaft of the gear unit, on which base body an axial projection is formed, wherein the axial projection is arranged on that side of the adapter flange which faces away from the electric motor, - wherein the axial projection is formed interrupted in the peripheral direction and the housing part protrudes into the interrupted region, wherein the adapter flange has on its side facing the electric motor first, axially directed, drilled holes, through which protrude connecting elements which also protrude through a bearing flange of the electric motor, characterised in that the drilling pattern of the first drilled holes has a discrete rotational symmetry relative to the axis of rotation of the input shaft, with bearings being received in the receiving part, the inner ring of which bearings is mounted in each case on the input shaft, with the annular base body being formed to be completely circumambient in the peripheral direction, with the adapter flange being oriented and centred on a receiving part of the gear unit coaxially with the axis of rotation of the input shaft, with the receiving part, by means of a cylindrical centring collar, being oriented, in particular centred, on the housing part of the gear unit, with the greatest value of the radial distance region covered by the axial projection as a function of the angle at circumference having four local maxima, with each angle-at-circumference region covered by a second drilled hole containing the angle at circumference belonging to a respective local maximum, with the axial projection having a finish-machined face facing towards the gear unit, the shortest radial distance of which face is constant in a partial region of the angle-at-circumference region covered by the axial projection. wherein the adapter flange has an annular base body formed rotationally symmetrically to the axis of rotation of an input shaft of the gear unit, on which base body an axial projection is formed, wherein the axial projection is arranged on that side of the adapter flange which faces away from the electric motor, - wherein the axial projection is formed interrupted in the peripheral direction and the housing part protrudes into the interrupted region, - wherein the axial projection is formed interrupted in the peripheral direction and the housing part protrudes into the interrupted region, wherein the adapter flange has on its side facing the electric motor first, axially directed, drilled holes, through which protrude connecting elements which also protrude through a bearing flange of the electric motor, characterised in that the drilling pattern of the first drilled holes has a discrete rotational symmetry relative to the axis of rotation of the input shaft, with bearings being received in the receiving part, the inner ring of which bearings is mounted in each case on the input shaft, with the annular base body being formed to be completely circumambient in the peripheral direction, with the adapter flange being oriented and centred on a receiving part of the gear unit coaxially with the axis of rotation of the input shaft, with the receiving part, by means of a cylindrical centring collar, being oriented, in particular centred, on the housing part of the gear unit, with the greatest value of the radial distance region covered by the axial projection as a function of the angle at circumference having four local maxima, with each angle-at-circumference region covered by a second drilled hole containing the angle at circumference belonging to a respective local maximum, with the axial projection having a finish-machined face facing towards the gear unit, the shortest radial distance of which face is constant in a partial region of the angle-at-circumference region covered by the axial projection.
