Electric motor with overload cut-out

Abstract

Abstract AN ELECTRIC MOTOR WITH PRE-SELECTED NUMBER OF REVOLUTIONS AND SWITCHABLE IN TWO DIRECTIONS OF ROTATION, WHICH COMPRISES A STATOR INCLUDING A STATOR-WINDING, A MOTOR SHAFT, A ROTOR FORMED AS A SLIDER AND MOUNTED ON THE MOTOR SHAFT, AS WELL AS INCLUDING AN OVERLOAD CUT-OUT MEANS, AND A MOTOR HOUSING RECEIVING THE STATOR AND THE ROTOR. THE OVERLOAD CUT-OUT MEANS COMPRISING AN OVERLOAD COUPLING OPERATIVELY CONNECTED WITH THE ROTOR AND THE MOTOR SHAFT, RESPECTIVELY, SO THAT THE OVERLOAD COUPLING TRANSMITS THE MOTOR TORQAUE FROM THE ROTOR TO THE MOTOR SHAFT. THE MOTOR SHAFT COMPRISES TWO SHAFTS DISPOSED COAXIALLY RELATIVE TO EACH OTHER AND ONE OF SAID TWO SHAFTS IS HOLLOW AND RECEIVES THE OTHER OF THE TWO SHAFTS, TO CONSTITUTE THE OUTPUT SHAFT AND CARRYING THE ROTOR. THE HOLLOW ONE OF SAID SHAFTS AND THE OTHER OF SAID SHAFTS ARE FORMED FOR A PART OF THEIR LENGTH AS A THREADED SPINDLE AND A THREADED SPINDLE NUT, RESPECTIVELY, ENGAGING EACH OTHER. THE OVERLOAD COUPLING COMPRISES A DISK-SHAPED BODY SITTING RIGIDLY ON THE HOLLOW ONE OF THE SHAFTS AND HAS ABOUT ITS PERIPHERY A PLURALITY OF EQUALLY DIVIDED AXIAL BORES.
