Abstract

1,027,600. Screw - and - nut actuators. H. KORTHAUS, and R. WILKE. Feb. 13, 1963 [Feb. 14, 1962], No. 5915/63. Heading B8J. [Also in Divisions F2 and H2] In an electric motor-driven linear displacing device comprising an internally threaded tubular shaft section 8 fast with the motor rotor 4 and a coacting elongated threaded operating rod 12 extending through the shaft section and secured against rotation but axially displaceable on rotation of the shaft section, and an electromagnetically operable brake for the rotor actuated when the rod reaches a limiting position, either a load or at least one spring 32, 33 returns the rod to its initial position upon failure of the motor and brake current. The rod 12 is secured against rotation by either a polygonal, e.g. square, part engaging a corresponding guide in a casing extension 15 or a longitudinal recess engaged by a key in a casing part 14, and coacts with the shaft section by means of a train of recirculating ball bearings 11. The brake includes friction linings 28 loaded to disengagement by springs 27 but engaged by attraction of a disc 25 by an iron ring 18 when a magnetizing winding 17 is energized via a rectifier by normally closed contacts of a motor relay which is de-energized by a limit switch 30 or 31 actuated by a cam 29 on a rod collar 34 when the rod reaches either of its end positions. In low power motors the switches may directly control the motor, and the rod may actuate the sliding contact of a potentiometer to give a remote indication and possibly automatic regulation of the rod position. The device is applicable to doors, flaps and weights.
