Electric machine, as well as gear drive unit including such a machine

The invention relates to an electrical machine (10) and containing the same transmission drive unit (12) comprising a housing (14), at one axial end of the housing (14) a rolling bearing (46) for supporting a rotor shaft (20) disposed , and the rotor shaft (20) having a driven-side area by the rolling bearing (46) passing from the housing (14) protrudes and at the output side area an output member (64) is arranged, and between the driven member (64) and the roller bearing ( 46) a centrifugal disc (74) rotationally fixed to the rotor shaft (20), and axial (between the slinger 74) and the roller bearing (46) on the housing (14) fixed to the housing, a rotor shaft (20) enclosing the sleeve (82) is arranged , which prevents the penetration of lubricant (72) in the roller bearing (46).
