1,112,119. Differential gear. STAL-LAVAL TURBIN AKTIEBOLAG. 25 Oct., 1966 [9 Dec., 1965], No. 47778/66. Heading F2D. A differential planetary gear 13 for driving contra-rotating propeller shafts 1, 3 of a ship, comprises a sun-wheel 12 on a driving-shaft 10, planets on a carrier 15 fast with a pinion 16 meshing a gear 17 on a sleeve 23 fast with shaft 1, and an annulus 18 coupled to a pinion 19 driving a gear 20 on shaft 3. Thrust between the shafts 1, 3 is taken by bearings 21, 22. The shafts 1 and 3 may be rotated in the same direction by introducing an idler pinion between pinion 19 and wheel 20. As shown, an additional identical drive from shaft 11 is provided, but only one, or more than two drives may be used, |
