<p>The drive has a slow-running electric motor comprising a rotor (1), and a drive pulley (3) comprising a drum shaft (2). The rotor is supported by a support bearing (4) i.e. movable bearing. An annular membrane disk (8) is arranged between a flange (7) and a support disk (9). Diameter difference is provided between circular rings (13, 14) of respective screw connections (11, 12) for producing elastic movement area of the membrane disk between the rotor and the shaft such that a coupling is produced between the motor and the pulley by the flange and disks.</p> |
