Abstract

An apparatus for assembling a composite arrangement including a plurality of functional elements each having an aperture for a shaft, in a predetermined angular position on the shaft, may include a plurality of retaining devices each intended for accommodating a functional element. The retaining devices may be arranged vertically one above another such that the apertures of the functional elements may lie on a vertical line. The apparatus may also include a vertically movable guide slide for the shaft so that a joining of the shaft with the functional elements may take place in a vertical direction. The apparatus may also include a heating device by which at least two functional elements may be heated simultaneously. The apparatus may further include a gripping device by which at least two functional elements which are to be joined may be removed together from the heating device and introduced into the retaining devices.

First claim

The invention claimed is:

1. An apparatus for assembling a composite arrangement including a plurality of functional elements each having an aperture for a shaft, in a predetermined angular position on the shaft, the apparatus comprising:
a plurality of retaining devices each intended for accommodating one of the plurality of functional elements, the retaining devices being arranged vertically one above another such that the apertures of the functional elements lie on a vertical line,
a vertically movable guide slide for the shaft, so that a joining of the shaft with the plurality of functional elements takes place in a vertical direction,
a heating device by which at least two of the plurality of functional elements are able to be heated simultaneously, and
a gripping device by which the at least two of the plurality of functional elements are able to be removed together from the heating device and introduced into the retaining devices of the apparatus.

2. The apparatus according to claim 1 , wherein each of the plurality of retaining devices includes at least one of:
a mount having a moulding fixing an angular position of the one of the plurality of functional elements accommodated by the retaining device, the angular position of the one of the plurality of functional elements corresponding to an angular position on the shaft, or
an assembly gripper, which fixes the one of the plurality of functional elements accommodated by the retaining device during the joining of the shaft with the plurality of functional elements.

3. The apparatus according to claim 1 , wherein the gripping device includes grippers constructed at least partially from a material which is not able to be heated inductively or are able to be cooled.

4. The apparatus according to claim 1 , wherein the heating device has at least two induction coils which are able to be controlled independently of one another.

5. The apparatus according to claim 2 , wherein the moulding of the mount of each of the plurality of retaining devices has an at least partial negative contour corresponding to a contour of the one of the plurality of functional elements accommodated by the retaining device, so that the one of the plurality of functional elements is able to be received by the retaining device at a precise angle.

6. The apparatus according to claim 1 , further comprising a device for holding at least one of a bearing frame and a cylinder head cover.

7. The apparatus according to claim 1 , wherein the heating device has at least one retaining balcony, on which at least one of the plurality of functional elements, which is to be heated, is able to be deposited, wherein the at least one retaining balcony is constructed at least partially from a material which is not able to be heated inductively or to be cooled.

8. The apparatus according to claim 1 , wherein each of the retaining devices is individually movable, so that the retaining device can assume at least two different retaining positions in at least one of which the retaining device is positioned so that the apertures of the functional elements lie on the vertical line.

9. A method for the thermal joining of a shaft with a plurality of functional elements each having an aperture for the shaft, comprising:
introducing, by a gripping device of an apparatus, at least two of the plurality of functional elements together into a heating device of the apparatus,
heating, by the heating device, the at least two of the plurality of functional elements,
moving, by the gripping device, the at least two of the plurality of functional elements together from the heating device and into retaining devices of the apparatus positioned so that the apertures of the at least two of the plurality of functional elements lie on a shared substantially vertical line,
pushing, by a vertically movable guide slide, the shaft through the apertures of the at least two of the plurality of functional elements,
equalizing a temperature to fix the at least two of the plurality of functional elements on the shaft, and
removing the shaft together with at least two of the plurality of functional elements fixed thereon from the apparatus.

10. The method according to claim 9 , further comprising positioning the retaining devices so that the apertures of the at least two of the plurality of functional elements lie on the shared substantially vertical line only directly before pushing of the shaft through the apertures.

11. The apparatus according to claim 2 , wherein grippers of at least one of the gripping device or the assembly grippers are constructed at least partially from a material which is not able to be heated inductively or are able to be cooled.

12. The apparatus according to claim 2 , wherein the heating device has at least two induction coils which are able to be controlled independently of one another.

13. The apparatus according to claim 11 , wherein the heating device has at least two induction coils which are able to be controlled independently of one another.

14. The apparatus according to claim 7 , wherein the material is ceramic.

15. The apparatus according to claim 2 , wherein each of the retaining devices is individually movable, so that the retaining device can assume at least two different retaining positions in at least one of which the retaining device is positioned so that the apertures of the functional elements lie on the vertical line.

16. The apparatus according to claim 3 , wherein each of the plurality of retaining devices includes a mount having a moulding that has an at least partial negative contour corresponding to a contour of the one of the plurality of functional elements accommodated by the retaining device, so that the one of the plurality of functional elements is able to be received by the retaining device at a precise angle.

17. The apparatus according to claim 2 , further comprising a device for holding at least one of a bearing frame and a cylinder head cover.

18. The apparatus according to claim 2 , wherein the heating device has at least one retaining balcony, on which at least one of the plurality of functional elements, which is to be heated, is able to be deposited, wherein the at least one retaining balcony is constructed at least partially from a material which is not able to be heated inductively or to be cooled.

19. The apparatus according to claim 4 , wherein each of the plurality of retaining devices includes a mount having a moulding that has an at least partial negative contour corresponding to a contour of the one of the plurality of functional elements accommodated by the retaining device, so that the one of the plurality of functional elements is able to be received by the retaining device at a precise angle.

20. An apparatus for assembling a composite arrangement including a plurality of functional elements each having an aperture for a shaft, in a predetermined angular position on the shaft, the apparatus comprising:
a plurality of retaining devices each intended for accommodating one of the plurality of functional elements, the retaining devices being arranged vertically one above another such that the apertures of the functional elements lie on a vertical line, the retaining devices including mounts each having a moulding with an at least partial negative contour of a corresponding functional element so that the corresponding functional element is able to be received at a precise angular position corresponding to the angular position on the shaft,
a vertically movable guide slide
