Definitions

  • the invention relates to a planetary gear according to the preamble of claim 1.
  • Such planetary gears are known in a two-stage design for driving oil pumps; both gear stages are enclosed by a common housing which is formed by a slim tube which is better adapted to the borehole diameter.
  • the tubular housing of the planetary gear is connected upwards and downwards by a further tubular housing of the same outside diameter; of these further housings, the upper one belongs to a motor and the lower one to a pump, which are assembled with the planetary gear to form a compact unit operating in the borehole.
  • a planetary gear is known (DE-A-1 295 948), in the housing of which a cylindrical hollow body is arranged at a considerable distance from the inner wall of the housing, on which two internal toothed rings are formed.
  • the hollow body is in the manner of a bending and torsion bar only in one of the two internal gear rings. zen in the axial direction relatively far away end portion attached to the housing.
  • Each of the two internal ring gears is assigned its own sun gear, one of which is connected via a torsion bar and the other via a hollow shaft to a common coupling part, the hollow shaft having the same torsional rigidity as the torsion bar.
  • Each of the two internal gears is connected to the associated sun gear by a set of planet gears, which are mounted in pairs on a bearing pin.
  • Each of the bearing bolts is supported on a planet carrier at its two ends and in an intermediate space between the two planet gears mounted on it.
  • the cylindrical hollow body which is attached to the housing of the planetary gearbox on one side only, on which the two internal gears are formed, as well as the separate drive of the two sun gears via a hollow shaft or a torsion bar arranged in it, especially in the radial direction, require considerable space, which the gearbox for one Use in boreholes or the like.
  • Another known planetary gear (EP-B-0 054 280) has an elongated, not particularly torsionally rigid sun gear, a correspondingly elongated internal toothing fastened to the gear housing and between the sun gear and the internal toothing on a planet carrier which are freely cantilevered bearing bolts on which three planet gears are mounted close to each other are.
  • the freely projecting arrangement of the bearing bolts is intended to ensure that their deflection and the torsion of the sun wheel are no longer kept as small as possible but are adapted to one another.
  • the direct abutment of the three planet gears mounted on a common bearing pin prevents them from individually adjusting to the internal toothing on the housing and the sun gear. This limits the load capacity of this known transmission for a given space requirement.
  • the invention is therefore based on the object of being used for cramped installation conditions, in particular in oil wells. to create a suitable planetary gear that is capable of transmitting particularly high torques.
  • Fig.l a section of a drive train provided for a petroleum pump with a planetary gear according to the invention, drawn as an axial section I-I in Fig.2, and
  • FIG. 2 shows the cross section II-II in Fig.l.
  • the planetary gear shown has a tubular housing 10, the axis of which forms the central axis A of the gear.
  • An internal thread 12 is formed at the right end of the housing 10 in FIG. 1, into which a corresponding threaded section of a tubular bearing body 14 is screwed, which in turn is screwed to a housing extension 16.
  • a housing extension 18 is screwed into the left end region of the housing 10 according to FIG.
  • a countershaft 20 is mounted in the bearing body 14 and has a thickening 22 for this purpose.
  • an externally toothed countershaft wheel 24 is formed, the outer diameter of which is somewhat smaller than that of the thickened portion 22, so that the countershaft 20 can be pushed into its illustrated position from right to left.
  • a countershaft planet carrier 26 is arranged around the countershaft gear 24, rotatable about the central axis A, to which a plurality of countershaft bearing bolts 28 are fastened, in the example shown five. These are arranged at an angular distance of 72 ° to each other parallel to the central axis A, with their two ends stuck in a bore without play section of the planetary gear carrier 26 and are secured against axial displacement by means of a radial grub screw 30.
  • An externally toothed countershaft planet gear 32 is supported on the countershaft bearing bolt 28 by means of a pair of needle bearings 34.
  • All countershaft planet gears 32 are in meshing engagement with the countershaft gear 24 and with an internal toothing 36, which is formed in one piece on the housing 10 in the example shown.
  • the internal toothing 36 forms, together with the previously described gear parts, the first stage of a planetary gear, which is referred to here as the additional gear.
  • the second gear stage also includes a planet carrier 46, which is arranged around the sun gear 40, also rotatable about the central axis A, and in turn carries five bearing bolts 48, which are arranged at angular intervals of 72 ° parallel to the central axis A.
  • the two ends of the bearing bolts 48 of the second gear stage are each in a bore section of the planet carrier 46 and in turn are secured against axial displacement with a grub screw 50 which is screwed radially into this planet carrier 46.
  • a peculiarity of the second planetary gear stage compared to the countershaft is that on each of the bearing bolts 48 two completely separate planet gears 52 are supported, again by means of a pair of needle bearings 54. Each of these planet gears 52 meshes on the one hand with the external toothing 42 of the sun gear 40 and on the other hand with the internal toothing formed on the housing 10, which thus also belongs to the second gear stage.
  • the planet gears 52 of the second gear stage which are mounted in pairs on a bearing pin 48, leave an intermediate space 56 between them which is essentially filled by a central projection 58 of the planet carrier 46.
  • One of the bearing bolts 48 of the second gear stage is supported in its central region on each of the five central projections 58.
  • each of the projections 58 has an axially parallel bore through which the associated bearing pin 48 is inserted without play.
  • Each of the second-stage planetary gears 52 is arranged between a pair of slide rings 60 fitted onto the associated bearing pin 48 and is thereby secured against axial displacement.
  • the second-stage planet carrier 46 is connected to a pump shaft 62 by means of a multi-groove profile 64 in a torque-transmitting manner and is secured against axial displacement by means of a radial grub screw 66.
  • the grub screw 66 is accessible through one of several radial bores 68 formed in the housing 10; these bores 68 are normally closed by a threaded plug 70.
  • the pump shaft 62 has an axial lubricant channel 72 and carries a sliding ring 74 at its mouth, which limits the axial displaceability of the assembly formed by the intermediate planet carrier 26 and the inner gear 40 second stage during operation.

Abstract

Dans un carter (10), sur lequel est formée une denture intérieure (36), et qui définit un axe central (A), est placée une roue solaire (40) qui peut tourner autour dudit axe et présente une denture extérieure (42). Dans un espace annulaire compris entre cette denture extérieure (42) et la denture intérieure (36) du carter (10), est placé un porte-satellites (46) qui peut également tourner autour de l'axe central (A). Sur le porte-satellites (46), sont fixés plusieurs axes de support (48) parallèles à l'axe central, qui sont décalés angulairement les uns par rapport aux autres, et sur lesquels au moins deux satellites (52) sont montés de façon à être séparés par un espace intermédiaire axial (56). Dans les espaces intermédiaires axiaux (56), les axes de support (48) reposent en outre sur le porte-satellites (46).
