Abstract

827,892. Differential gearing; converting rotary to reciprocating motion. HINDMARCH, T. April 15, 1958 [April 15, 1957], No. 12266/57. Classes 80 (1) and 80 (2). [Also in Group XXXIII] The shaft from a prime mover is coupled at A to transmit power via a clutch B and pinion C to a wheel D secured to the shaft 13 which drives a screw propeller (see Group XXXIII) the pitch of the blades of which is controlled by a rod 10 actuated through differential gearing by a motor 45 or emergency handwheel 46. In the embodiment of Fig. 4, the operating-rod 10 is prevented from rotating by a key 34 and has fixed thereto a screwed member 33 in a nut 35 having a gear 36 which drives gear 37 and hence carrier 38 of the differential gear, and a gear 39 which drives gear 40 and hence a gear 41 at twice the speed of the carrier 38. A gear 42, similar to gear 41, is normally stationary but when this is rotated by means of worm-wneel 43 and worm 44 driven by said motor, the nut 35 rotates relative to the propeller shaft 13 and causes fore or aft movement of the rod 10 to alter the pitch of the propeller blades. In the case where the pitch is altered by rotary movement of the operating rod, the key 34 is removed and the nut 35 fixed to said rod, or the gearing shown in Figs. 7 and 8 may be used. Here a pinion 60 attached to the propeller shaft 13 meshes with a pinion 61 rotatably connected with a sun pinion 62 meshing with planet pinions 63 which in turn mesh with an equal number of like planet pinions 64. The planet pinions are carried on pins 65 on a carrier 66 free to rotate on a stationary pin 67. The planet carrier 66 has teeth 68 in mesh with a pinion 69 rotatably connected with the operating rod 10. Meshing with planet pinions 64 is a sun pinion 70 which is rotatably connected to a pinion 71 in mesh with a pinion 72 connected with the above-mentioned motor 45. Gear ratios are such that when the propeller shaft 13 and operating rod 10 will rotate together at the same speed with no rotation of the sun pinion 70, but rotation of the pinion 70 will cause rotation of the rod 10 relative to the shaft 13 and so alter the pitch of the propeller blades.
