Abstract

788,346. Screw and nut actuators. HOOVER, V. A. Jan. 31, 1956, No. 3041/56. Class 78 (3). [Also in Group XXIV] A screw and nut actuator particularly for aircraft comprises an actuating screw S movable longitudinally through a driving nut N which is rotatably supported in a frame 18 by bearings 22, 24. The centre portion only of the nut is threaded at 16 and guide collars 58, 59 secured to the frame 18 support the screw against transverse deflection. The nut is driven by an electric motor 26 through gearing 63, a torque limiting device 65, and gearing 69, 70, 78.
