Abstract:
A planetary gear for mounting on an electromotor, the planetary gear comprising:planetary gear wheels (10) supported by a rotating planetary carrier (8) that forms an output of the planetary gear and the planetary gear wheels are in constant engagement with a sun gear (12) and an annular gear (14) positioned in a housing (2), the sun gear (12) being connected to a rotatable sun gear shaft (4), the sun gear shaft (4) having a hollow receiving section (16) for directly receiving an output shaft of an electromotor; a sealing element (22) being provided between the sun gear shaft (4) and the housing (2), wherein the sealing element (22) is spaced axially from the receiving section (16) for the output shaft of the electromotor, and located on a first axial section of the sun gear shaft (4) having a smaller outer diameter than a diameter of the receiving section (16); and a sun gear bearing (28) for the sun gear shaft (4) is located radially inward of an inner ring of a planetary carrier bearing (30), at least partly within a space occupied by the planetary carrier bearing (30), and axially between an end stop of the receiving section (16) and the planetary gear wheels.
