Definitions

  • This invention relates to epicyclic gear trains.
  • Epicyclic gearing is especially good since it is compact and balanced and, particularly with the cantilever mounting of the planets as described in several Patents, such as GB-B-1101131, GB-B-1456085, GB-B-1448059, GB-B-1508999 and EP-0003894, it is ideal for long periods of continuous unattended use.
  • an epicyclic gear train assembly comprising a mounting, a main shaft rotatably carried by the mounting, and an epicyclic gear train carried co-axially by the shaft, the gear train comprising a first planet carrier fixed to the shaft, an intermediate member providing a first sunwheel in co-operation with planets on the first carrier and a second planet carrier, an output member providing a second sunwheel in co-operation with planets on the second carrier, and annular gearing for co-operation with the " planets of both carriers fixed to said mounting.
  • the planets of the first carrier will be identical to those of the second and they will be carried on flexible cantilevers projecting from their respective carriers. However, there may be more planets in the first epicyclic than in the second, to carry the high input torque.
  • the shaft may be tubular and adapted to accommodate mechanism for altering the blade pitch of a propeller mounted at one end.
  • each stage can readily be made to step-up the ratio by more than 3:1, so that with the two stages the total step-up may be about 10:1. All this will be achieved in a very compact
  • each stage having annular gearing fixed to said mounting and, except for the last stage, a sunwheel which is part of a member providing a planet carrier for the next stage.
  • the output member will generally be geared to another, parallel shaft, and this can provide a further step-up in speed.
  • a hollow shaft 1 is supported in a mounting 2 between axially spaced bearings 3 and 4.
  • the mounting is a composite construction to make assembly possible, but its various components will not be individually identified and described.
  • the first epicyclic 5 has a carrier 7 fixed to the shaft 1 and its planets 8, cantilever mounted as mentioned above, mesh with an annulus 9 fixed to the mounting 2 and with a sun 10 which is at one end of a intermediate member 11 freely encircling the shaft 1.
  • This member also provides at its other end a planet carrier 12 for the second epicyclic 6 whose planets 13 mesh with an annulus 14 fixed to the mounting 2 and with a sun 15.
  • the annuli 9 and 14 are part of a single ring, with the annulus 14 and sun 15 being slightly smaller than the annulus 9 and sun 10.
  • the planets 8 are identical to the planets 13, but there will generally be more of them to accept the high input torque. For example, there may be eight planets 8 and four planets 13.
  • the sun 15 is at one end of a member 16 journalled on the shaft 1 and having a larger gear wheel 17 at its other end meshing with a gear 18 on an output shaft 19 parallel to the shaft 1 and also journalled in- the mounting 2.
  • the input When applied to a windmill, the input will be from a propeller mounted on the left hand end of the shaft l, beyond the scope of the drawing, and that will have variable pitch blades controlled by a rod 20 co-axially within the shaft 1.

Abstract

L'invention se rapporte à un train d'engrenages épicycloïdaux, qui forme unn système d'engrenage multiplicateur compact pour l'arbre (1) d'un moulin à vent. Dans sa conception de base, cet ensemble comprend deux engrenages épicycloïdaux (5, 6) montés en tandem coaxiallement par rapport à l'arbre (1), le système d'engrenage annulaire (9, 14) étant fixé au bâti de montage (2). L'énergie à l'entrée s'applique aux porte-pignons planétaires (7) du premier engrenage épicycloïdal (5) et un élément intermédiaire (11) forme la roue solaire (10) de ce premier engrenage épicycloïdal, tandis que le porte-pignons planétaires (12) forme celle du second engrenage épicycloïdal (6). L'énergie à la sortie est produite par la roue solaire (15) de ce second engrenage épicycloïdal (6) par l'intermédiaire d'un autre sytème d'engrenage multiplicateur (17, 18) pour être transmise à un arbre parallèle (19). Cet ensemble est monté entre des paliers de roulement (3, 4) pour l'arbre (1), ces paliers pouvant être tubulaires pour loger un méchanisme (20) de commande du pas variable de l'aubage.
