Definitions
- FIG. 1 shows a known from the prior art planet carrier 101 with a recess 103 for receiving a planetary pin 105.
- the recess 103 is surrounded by a collar 107.
- the recess 103 fixes the planet pin 105 positively in the radial direction.
- An inventive planet carrier has at least a first recess and a second recess, each serving to receive a planetary pin.
- the first recess and the second recess are formed so that they can collectively receive a single planetary pin.
- the first recess and the second recess are each a planetary seat.
- receiving the planet pin means that the planet pin is inserted into the first recess and / or into the second recess and the first recess and / or the second recess fix the planet pin.
- the fixation takes place at least in the axial direction.
- the planetary pin is also fixed in the radial direction.
- press dressing preferably a shrinkage dressing is suitable.
- the invention is based on the idea of increasing the rigidity of the planet carrier in the region of the first recess in that the planet carrier is made more massive around the first recess towards the second recess.
- a running at the height of the first recess in the radial direction through the planet carrier cross-section thus cuts to the second recess towards more material. This is synonymous with a larger area or a larger area of the cross section.
- the first cross section is arranged closer to the second recess, in particular in the axial direction, ie in the direction of the axis of symmetry of the planetary bolt or the axis of symmetry of the first recess or the axis of symmetry of the second recess or the axis of rotation of a planetary gear mounted on the planetary pin. as the second cross section.
- This means that the first cross section is arranged from the second cross section - in particular in the axial direction - to the second recess.
- the second cross section and the second recess are located on different sides of a plane in which the first cross section is located. The first cross section is thus located on the same side of a plane in which the second cross section is located, as the second recess.
- the first cross section lies with a mouth of the first recess in a plane.
- This mouth may be the only mouth of the first cavity.
- the first recess may have two mouths.
- the mouth lying in a plane with the first cross section is located closer to the second recess than the one of the other two orifices. The other of the two openings and the second recess are thus located on different sides of said plane.
- planetary carriers usually have two oppositely disposed side pieces. Between the side pieces run the planet pins. Furthermore, areas are left between the side pieces in which the planet gears can rotate.
- At least one side piece is provided that for enlarging the surface of the first cross section and thus contributes to increasing the rigidity in this area. This has the advantage that no additional material is required.
- Fig. 2 shows a recess for receiving a planetary pin in the form of a hollow cylinder open on one side.
