Abstract

627,004. Jack-type actuators. MILES AIRCRAFT, Ltd., and HAWKINS, A. S. April 26, 1944, No. 7825. [Class 78 (iii)] In a jack-type actuator particularly for use on aircraft for operating cooling gills, bomb doors or the like, comprising a screw driven through reduction gear by an electric motor, the gearing and motor are arranged co-axially along the axis of the screw. In the embodiment shown in Figs. 1, 4 the ram 8 slidably mounted in a bearing 12 in an extension 7 of a casing 1 is actuated by a worm 10 driven through epicyclic gearing by an electric motor 4 of the permanent magnet type. A keyed connection 13 prevents rotation of the ram. The gearing comprises gear carriers 18 which are fitted with planet gears 19 meshing with a toothed annulus 16 secured against rotation by screws 17, and all, except one which is secured to the worm 10, have a sun wheel 21 meshing with the planet gears of an adjacent carrier. The carrier adjacent the motor 4 has its planet gears in driving connection with a pinion 20 on the motor shaft. The worm 10 is mounted in a thrust-and-journal bearing 9. Reference has been directed by the Comptroller to Specification 587,742.
