Abstract

421,889. Epicyclic toothed gearing. ROWLEDGE, A. J., Ellerslie, Trowells Lane, Mickleover, ELLOR, J. E., Grandell, South Drive, Chain Lane, Littleover, and RUBBRA, A. A., Red Roofs, Carlton Avenue, all in Derby. June 23, 1933, No. 17874. [Class 80 (i)] [See also Group XXXIII] Relates to gearing for driving two coaxial airscrews in opposite directions. In the arrangement shown in Fig. 1, the engine crankshaft a carries a sun-wheel c<2> in mesh with planet wheels d connected to stepped planets d<1>, d<2>. The cage e, e<3>, e<1> is connected to the sleeve f carrying the hub f of one propeller ; a sun wheel g on the shaft b carrying. the hub b<1> of the other propeller is in mesh with the planets d<1> ; and the planets d2 mesh with a reaction sun g<2>. In a modification, not shown, the crankshaft drives an annular wheel in mesh with one of two stepped planet wheels mounted in a cage integral with a sleeve for mounting one propeller hub, the other propeller being mounted on a shaft having a sun wheel in mesh with the planet wheel, while the other planet wheel is in mesh with a fixed reaction member. In the form shown in Fig. 3, the crank shaft drives a bevel gear m in mesh with one bevel m<1> of a double bevel planet wheels m<1>, m<2> mounted on a shaft n fixed to the propeller shaft b. A bevel wheel o on the hub sleeve f is also in mesh with the bevel m<1>, while the bevel m<2> runs on a fixed reaction crown-wheel m<3>.
