Abstract

610,205. Screw-and-nut gearing. ENGLISH ELECTRIC CO., Ltd., and WOODFORD, C. G. A. April 1, 1946, No. 10013. [Class 80 (iii)] [Also in Group XXX] An electrical actuator in which the thrust is transmitted from a member 8 to a member 10, comprises a righ-hand and left-hand threaded member 6 in screw-and-nut cormection with the members 8, 10. Rotation of the member 6 by an electromotor 1 driving through gearboxes 2, 3 to a gear-wheel 5 on the member 6 causes the longitudinal position of the members 8, 10 to vary with respect to each other. One of the throw-threads is of the ball-bearing type 6b and the other of the Acme type 6a. In the latter case torque reaction members such as 17a attached to the actuator casing 4 engage lugs such as 8b projecting from the member having the Acme thread. In a modification, the member 6 is threaded internally and the member 8 is threaded externally as a bolt engaging this internal thread.
