Definitions

  • the invention relates to a planetary gear according to the preamble of claim 1.
  • a planetary gear is a component of a planetary gear.
  • the planetary gear has, in addition to a plurality of planet gears, an externally toothed sun gear and an internally toothed ring gear.
  • the planet gears are usually externally toothed and mesh with the sun gear and / or the ring gear. Furthermore, the planet gears are rotatably mounted in a planet carrier.
  • a planetary gear is usually designed to have a transmission degree of freedom of two.
  • gearbox degree of freedom also known as gear ratio
  • gear ratio can be found in "Dubbel” (Karl-Heinrich Grote, Jörg Feldhusen: “Dubbel”, 22nd Edition, 2007). Accordingly, either the planet carrier rotatably carried while the sun gear and the ring gear are rotatable, the sun gear rotatably carried, while the planet carrier and the ring gear are rotatable, or the ring gear rotatably carried, while the planet carrier and the sun gear are rotatable. In this case, the axes of rotation of the planet carrier, the sun gear and the ring gear coincide. In the case of a rotatable planet carrier, the axes of rotation of the sun gears move about the axis of rotation of the planet carrier.
  • a stepped planetary gear is a planetary gear with two gears whose pitch circle diameter differs known.
  • stepped planets are made in one piece.
  • a grinding spout between the two gears must be provided. This results in that the width of the planetary gear increases in the axial direction.
  • the object of the invention is to make available a stepped planetary device, bypassing the disadvantages inherent in the solutions known from the prior art.
  • the stepped planet should be compact and easy to manufacture.
  • the planet gear has a first toothing and a second toothing.
  • the planet gear is a stepped planet, wherein a pitch circle diameter of the second toothing is greater than a pitch circle diameter of the first toothing.
  • the first toothing and the second toothing are designed to mesh with a toothing of a further toothed wheel.
  • the further gear may be a sun gear or a ring gear.
  • the planetary gear with a planet carrier, in which the planet gear can be rotatably mounted, the sun gear and the ring gear form a planetary gear.
  • the planetary gear according to the invention is in two pieces, formed with a first piece and a second piece.
  • the first piece has the first toothing and the second piece has the second toothing.
  • the first piece is thus provided with the first toothing, the second piece with the second toothing.
  • a first toothing and a second toothing are provided.
  • the first piece has the first gear teeth, or forms the first gear teeth.
  • the second piece has the second passport tion, or forms the second splines.
  • the second spline can be pushed onto the first spline so that the first spline and the second spline intermesh positively.
  • the first toothing is an external toothing and the second toothing is an internal toothing. Due to the positive connection between the first gear teeth and the second gear teeth, the second piece is rotatably connected to the first piece. Furthermore, a radial fixation of the second piece in the first piece is effected by the positive connection between the first toothing and the second toothing.
  • the second piece can be fixed non-positively in the first piece.
  • a frictional connection between the first piece and the second piece can be made by the second dovetailing is shrunk onto the first spline.
  • the second piece is positively fixed in the axial direction in the first piece, for example by means of retaining rings.
  • the two-piece design of the planetary gear makes it possible to manufacture the first toothing and the second toothing independently of each other. A grinding spout is therefore not required. This favors a compact design of the planetary gear.
  • a part of the first toothing forms the first toothed toothing.
  • the first piece thus has exactly one gearing. This meshes not only with a toothing of another gear, but also acts as the first spline.
  • the second toothing can be pushed onto the first toothing, so that the first toothing or the part of the first toothing that forms the first toothed toothing, and the second toothed toothing intermesh positively and optionally also non-positively.
  • the planetary gear training further exactly three gears: the first gear, the second gear and the second gear teeth.
  • the planetary gear can be rotatably mounted on a planet shaft.
  • the planetary pin is rotatably fixed in the planet carrier, that is, the planetary pin is not rotatable relative to the planet carrier.
  • a rotatable mounting of the first piece in the planetary bolt is preferred.
  • the planetary pin causes a radial fixation, preferably also an axial fixation of the first piece.
  • At least one bearing serves to rotatably support the first piece in the planetary pin.
  • the bearing is at least partially disposed inside the planetary gear.
  • the interior of the planetary gear is thus a cavity within the planetary gear. In the present case, this cavity has two openings through which the planet pin extends in the mounted state.
  • the bearing is completely inside the planetary gear.
  • each bearing by means of which the first piece can be rotatably mounted in the planet shaft, at least partially, preferably completely located in the interior of the planet gear.
  • Fig. 1 a hollow stepped planetary
  • Fig. 2 is a massive stepped planet.
  • a devisnplanet 101 of FIG. 1 has a first piece 103 and a second
  • the first piece 103 includes a first toothing 107.
  • the second piece 105 includes a second toothing 109.
  • the second piece 105 is provided with a designed as an internal toothing splines 1 1 1.
  • the first toothing 107 extends in the axial direction over the entire width of the first piece 103.
  • the first toothing 107 correspondingly not only serves to mesh with another toothed wheel, such as a sun gear, but also extends over a region that functions as a toothed wheel Gearing acts.
  • This interference toothing forms a positive connection with the toothing teeth 1 1 1 of the second piece 105 when the second piece 105 is pushed onto the first piece 103.
  • the first piece is 103 and the second one
  • Piece 105 relative to each other rotationally fixed and translationally fixed in the radial direction.
  • Fig. 2 shows a stepped planetary 101 with solid first piece 103.
  • the bearings 1 15 are arranged outwardly offset here and with the outer rings in the planet carrier 1 19 fixed.
  • the first piece 103 of the stepped planetary 101 is fixed.
