Device for positioning multiple function elements

A method for thermally joining a shaft with multiple function elements having a recess for the shaft using a positioning device comprising:

• placing function elements angle-accurately in a respective moulding of a plurality of mountings such that recesses of the function elements lie on a common substantially vertical straight line,
• at least one of cooling the shaft and heating the function elements,
• pushing the shaft with a vertically moveable guide carriage through the recesses of the function elements,
• fixing the function elements on the shaft via a temperature equalisation fixing, and
• removing the shaft including function elements fixed thereon from the device.

A positioning assembly, comprising:

• a shaft;
• a plurality of function elements each having a recess for receiving the shaft in a predetermined angle position on the shaft;
• and
• a positioning device having multiple mountings for receiving the function elements, the mountings including a moulding to receive a function element in a predetermined angle position corresponding to the predetermined angle position on the shaft, wherein the mountings can be positioned such that the recesses of the function elements are arranged on a common straight line, and the mountings arranged vertically on top of one another so that the common straight line runs in vertical direction;
• wherein the positioning device includes a vertically moveable guide carriage for the shaft, the guide carriage configured for joining the shaft with the function elements in the vertical direction.
