Abstract

1314062 Screw and nut gearing ASSOCIATED ENG Ltd 19 April 1971 [4 Feb 1970] 5433/70 Heading F2Q A screw and nut mechanism consists of a pair of meshing pinions 13, 14 fixed on shafts 11, 12 and a second meshing pair 15, 16 of differing ratios, the pinion 15 rotating with shaft 11 but being free to move axially along it, while the pinion 16 has screw threaded engagement with shaft 12. Pinions 15, 16 are mounted in a cage 18 so that if shaft 11 is rotated, e.g. by an electric motor 19, the cage and pinions move bodily along the shafts, the cage having a lug 20 serving as the output member. Pinions 13, 14 have slightly differing numbers of teeth, the inverse arrangement being used for pinions 15, 16.
