A method and an arrangement for adjusting the disc brake of a squirrel cage motor, the squirrel cage motor (1) comprising a stator (3), a rotor (5) arranged on a shaft (10) of the motor (1) and comprising a deflector (7) for deflecting part of the magnetic field of the stator (3) to a stray flux of the magnetic field of the rotor (5) in the direction of the shaft (10), the motor (1) further comprising an armature (9) arranged on the shaft (10), a flexible element arranged between the deflector (7) and the armature (9) for pushing the armature (9) away from the deflector (7), at least one brake disc (16) supported to a motor (1) frame (2) via at least one slot (18), at least one trigger gear (17) arranged on the shaft (10) and a shaft (10) bearing (20). When the motor (1) is turned off, an air gap (15) forms between the deflector (7) and the armature (9), the size of which is adjusted with at least one adjusting piece (24) movable inside a bearing surface (38) in an inner ring (32) of the bearing (20) in the longitudinal direction of the shaft (10), so that the movement of the adjusting piece (24) causes a movement of the armature (9) in the longitudinal direction of the shaft (10) so that the size of the air gap (15) changes. <IMAGE> |
