A rapidly rotating electric drive with ≧ 12.000 minutes - 1 and 400hz with a gear system is connected by a magnetic coupling in a drive housing

摘要

Electric drive (1) with a transmission (2), connected by a magnetic clutch (3) in a drive housing (4), in which the escape of transmission oil from the transmission (2) and its penetration into the electric drive (1) by a sealing element in the form of a partition wall (5) composed of a non-magnetic material and not narrow material is avoided between a first magnetic plate (3.1) and a second magnetic plate (3.2) is arranged, whereby the electric drive (1) to rotate rapidly with & 12.000 min^–1 and 400 hz is, the drive housing (4) a housing part (4.1) with a left-hand outer thread (4.1.1), in which the second magnetic plate (3.2) on the shaft of the transmission (2) is mounted and a housing part (4.2) with a right-hand external thread (4.2.1), in which the first magnetic plate (3.1) on the shaft of the electric drive (1) is mounted, whose end faces which are arranged relative to one another with axial bores and arranged in it, the pins or splines (6) are provided, through which the two housing parts (4.1, 4.2) are secured against rotation relative to one another, and wherein a union nut (7) with a left-hand internal thread (7.1) on the one hand and a right-hand internal thread (7.2) provided on the other hand, on the external threads (4.1.1, 4.2.1) of the housing parts (4.1, 4.2) is arranged and the housing parts (4.1, 4.2) movably connects to one another, as a result of which they to one another as well as to be movable away from one another, and the air gap between the magnet plates (3.1, 3.2) and thus the this way and to reduce or increase the torque from the outside can be controlled manually.
