METHOD AND APPARATUS FOR ADJUSTING THE AXIAL PLAY BETWEEN THE ROTOR AND THE BEARINGS FITTED TO THE STATOR OF AN ELECTRIC MOTOR

摘要

1. Apparatus for adjusting the axial play between the rotor and the bearings (4, 5), which are fixed to the stator of an electric motor, in which a spacing sleeve (32) which is pressed on to the rotor shaft (2) and is displaceable under axial pressure, projects at least partially into a recess in the rotor and can be pressed there into, characterised in that in an electric motor having an insulating end plate (3), the end face of which abuts against the stack of rotor laminations (1), and which has formed on it an axially-projecting collar (31) which surrounds the rotor shaft (2), the recess (33) is provided in the collar (31) of the insulating end plate (3), and the spacing sleeve (32) can already by pressed into the recess (33) before the latter is pressed on to the rotor shaft (2).
