Device for setting the axial play of the rotor an electric motor

The furnace provides a device which is suitable for the axial play of the rotor of electric motors simple smocks on the predetermined ones. Value to be set-1 © η The rotor of an electric motor is feot on a shaft attached, and the V / ell® is stored in bearing bodies, which are firmly connected to the stand of the hotor

The Heuerung is the fact that the rotor body in the area of the shaft has concentric therewith extending tapered recesses into which are triangular or quadrangular thrust washers used with flattened peaks, the Dep lachungen bent. · And are all on the same circular arc ' with respect to the disc center point that the

The remaining space between the pressure vessels and the bearing bodies is filled with thrust washers, and that by means of axial. Pressure on the pressure washers, which are then printed into the .leonic recesses, the axial run is achieved '' adjustment · ■ ba: e is 'through.' The innovation has the advantage that _; the motor without the necessary Berüclcsichtigüns ibcialspiels be assembled, and can, that the adjustment of the axial play is then carried on the finished motor * The pressure on the pressure plates can for example take place in that is pressed onto the rotor shaft.
