Abstract
A device for positioning a shaft relative to a functional element including at least one hub for the shaft. The device may include a tailstock for axially aligning the shaft with respect to the at least one hub of the functional element. The tailstock may include a radially adjustable centring cone for the shaft. The tailstock may have an outer diameter that is smaller than an inner diameter of the at least one hub.
Claims20
A device for positioning a shaft relative to a functional element including at least one hub for the shaft, the device comprising:
- a tailstock for axially aligning the shaft with respect to the at least one hub of the functional element;
- the tailstock including a radially adjustable centring cone for the shaft;
- and
- wherein the tailstock has an outer diameter that is smaller than an inner diameter of the at least one hub.
The device according to claims 4, wherein:
- the tailstock includes at least three radially extending internal threads structured and arranged to receive a grub screw;
- a spring and a ball are arranged in front of the grub screw in a screwing-in direction;
- and
- the ball, in an installed state, engage the annular groove and centre the centring cone relative to the tailstock.
A method for thermally joining a shaft to at least one functional element having a hub for the shaft via a device, the method comprising:
- at least one of cooling the shaft and heating the at least one functional element;
- adjusting a centring cone of a tailstock of the device through the hub, the centring cone configured to adjust radially relative to the tailstock and to engage the shaft, the tailstock having an outer diameter that is smaller than an inner diameter of the hub;
- moving the shaft into engagement with the centring cone of the tailstock via a guide carriage;
- when the shaft is not coaxially aligned with the hub and is pushed against the at least one functional element, radially adjusting the shaft via radially adjusting the centring cone;
- fixing the at least one functional element on the shaft via awaiting a temperature equalisation;
- and
- removing the shaft and the at least one functional element fixed thereon from the device.
A device for positioning a shaft relative to a functional element, comprising:
- a tailstock having an outer diameter that is smaller than an inner diameter of a hub of the functional element;
- a centring cone configured to axially engage the shaft;
- and
- wherein the centring cone is adjustably connected to the tailstock such that the centring cone is radially adjustable relative to the tailstock.
