Apparatus for assembling a composite arrangement

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.

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 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, the heating device having at least two induction coils independently controllable, 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.
