Definitions
- the invention relates to a rotor for a camshaft adjuster.
- the present invention relates to the genus of hydraulic camshaft adjusters.
- Hydraulic camshaft adjusters may for example be designed as a camshaft adjuster, which operate on the vane principle.
- the described invention relates to a type of camshaft adjuster having a stator and a rotor.
- the rotor is located inside the stator and has a number of vanes.
- One or more wings form with corresponding counter-elements of the stator at least two chambers which are offset from each other in such a manner that filling a first chamber results in at least partial emptying of the second chamber and thereby simultaneously rotating the rotor is effected.
- a camshaft joined to the rotor is rotated.
- the camshaft can thus be adjusted by means of a hydraulic use of a fluid, for example an oil, at least between a first position and a second position using such a camshaft adjuster.
- the invention has for its object to improve a rotor for a camshaft adjuster.
- the object is achieved with a rotor for a camshaft adjuster with the features of claim 1.
- the object is achieved with a joining set with the features of claim 12.
- the rotor is intended for rotation about a rotation axis.
- the rotor comprises: a first end face,
- the at least one wing is arranged at the central area. From the central area, the wing extends directed radially pointing away.
- At least two camshaft centering elements are arranged on the inner side surface.
- the camshaft centering elements are designed as elevations.
- the rotor for rotation about an axis of rotation is to be understood in the described situation as providing rotation in an angular range required for adjusting a camshaft from a first position to a second position and back.
- the concept of rotation about a rotation axis is not to be understood as meaning that complete rotation is required.
- the term of the receiving end opposite the first end face is to be understood as being a first end face and a second end face of a same body, wherein the second end face is located as a receiving end face on a side of the rotor other than the first end face.
- the rotor is a body having a basic geometric shape that can be derived from a cylindrical body.
- the first end face and the receiving end face are oriented substantially parallel to one another. A parallel orientation of the first end face to the second end face is not only easier to manufacture but also leads to a much easier to achieve reduction of leakage of the system.
- the term of the receiving end face is to be understood to mean that it is at the receiving end face to a front side, which is suitable and preferably also provided for, the camshaft in a joining of the
- central region designates that part of the rotor which, in the assembled state of the camshaft, comes into contact with the rotor directly or indirectly with the camshaft.
- a wing Arranged starting from the central region is a wing, wherein the wing is preferably connected in a materially bonded manner to the central region.
- the rotor is a rotor having a number of at least three
- Wings The notion of a radially pointing away from the central region alignment of the wing or the wing is to be understood in particular to the effect that a focal plane of the wing, which also includes the axis of rotation, a predominantly radial direction away from the axis of rotation direction component and against this a smaller proportion of a tangential order Having the axis of rotation facing share.
- the wing is bent, for example, in a direction tangential to the axis of rotation.
- the wing has, for example, side surfaces which are tilted relative to a plane containing the axis of rotation.
- the wing or all wings have a plane of symmetry in which the axis of rotation of the camshaft is located.
- the term of the camshaft receiving recess is to be understood that in the central region of the rotor is a depression which is suitable for a partial introduction of the camshaft, provided that this camshaft has a suitable cross-sectional area and cross-sectional shape. It should not be ruled out that the camshaft receiving recess is a through hole that completely penetrates the rotor. Preferably, however, the camshaft receiving recess is a recess which finds a bottom in a volume of the central portion of the rotor.
- this base is positioned completely perpendicular to the axis of rotation, that is to say that the camshaft receiving recess substantially forms a half-space, which forms a cylindrical cavity or a substantially cylindrical cavity with an imaginary completed receiving end-face cover.
- inner side surface refers to the inner surface of the camshaft receiving recess resulting in the central portion of the rotor without the bottom resulting from incomplete penetration of the rotor.
- the inner side surface is, as it were, the part of the lateral surface of the above-described cavity, which does not form the bottom or an imaginary cover of the cavity described above. It should not be prevented by possibly existing on the inner surface edges that in the definition used here, the entire once the axis of rotation circumferential surface is referred to as an inner surface.
- the inner side surface results as a lateral surface of this circular cylindrical cavity.
- At least two Nockenwellenenzentneriata are arranged on the inner side surface.
- the camshaft centering elements are elevations, which rise from the volume of the rotor on the inner side surface.

Due to the high rotational symmetry of a round camshaft receiving recess proves to be particularly particularly advantageous in that the production is considerably simplified and a particularly advantageous to achieve maintaining the centering over a high number of rotation cycles is effected.
- the rotor for example, it may also be provided that the rotor has an odd number of camshaft centering elements. An odd number of Nockenwellenzentrierettin results in the advantage that a centering of a camshaft for elementary geometric reasons can be made in a particularly advantageous manner. This is especially true in the case of a round opening area of
- the rotor has exactly three camshaft centering elements.
- the rotor has three Nockenwellenenzentrieriata which in their
- the geometric centers of gravity of the camshaft centering elements form an equilateral triangle in a plan view of the rotor, for example with the axis of rotation as the visual axis.

- the term angular distribution here refers to the geometric center of gravity of both the camshaft centering elements and the vanes.
- the geometric center of gravity described above in just this plane of symmetry.
- An embodiment of the rotor can be characterized, for example, in that the at least two camshaft centering elements rise radially in the direction of the axis of rotation along a circumference of the circumference of the inner side surface.
- camshaft centering elements are elevations which are in a part of the circumference of the inner side surface described above in an already described round configuration.
- an angular extent of at least two, preferably all, camshaft centering elements is the same.
- the circular circumferential section of the inner side surface, on which a camshaft centering element designed as an elevation is arranged is the same for at least two camshaft centering elements.
- this angular extent is the same for all camshaft centering elements, since in such a case
- Camshaft centering elements are provided in the same configuration.
- rotor in a further embodiment of the rotor can be provided, for example, that an angular spacing between each two adjacent Nockenwellenenzentrierijnn is the same. In a preferred embodiment, this is the case for all over the entire circumference of the inner side surface existing Nockenwellenenzentrierieri. This results in a high symmetry of the arrangement of the camshaft centering elements with the corresponding advantages associated therewith for a good centering of the camshaft.
- the rotor is joined from exactly two separately manufactured rotor parts.
- a joining of the rotor from two rotor parts has the particular advantage that, for example, lubricant supply lines in the interior of the rotor by means of
