Electromagnetic coupling for transmitting torque to e.g. fan, of internal combustion engine, has rolling body rolling between internal raceway and middle raceway, and middle raceway and external raceway of bearing

摘要

The coupling (1) has eddy current couplings (16, 17) arranged at a side of a flange, where a coupling half (17a) of the coupling (17) is connected with a middle raceway (12) of a bearing (3) and another coupling half (17b) is connected with a drive shaft (4). The coupling half (17b) passes externally and radially in a coupling half (16b) of the coupling (16), when another coupling half (16a) of the coupling (16) is connected with the flange. A rolling body (14) rolls between an internal raceway (11) and the middle raceway, and the middle raceway and an external raceway (13) of the bearing.
