Abstract

A method and device for mounting a plug in a hollow shaft is disclosed. The device includes a holding device for holding the plug to be mounted and a joining device for sliding the hollow shaft onto the plug held in the holding device. The holding device is radially adjustable relative to an axis of the hollow shaft to compensate for an axial offset between the axis of the hollow shaft and an axis of the plug. The joining device can be inclined to compensate for an inclined position of the axis of the hollow shaft and the axis of the plug. The method includes pressing the joining device onto the hollow shaft from above and adjusting the holding device with the plug radially to the hollow shaft if the axial offset is present, and inclining the joining device if the inclined position is present.

First claim

The invention claimed is:

1. A device for mounting a plug in a hollow shaft, comprising:
a holding device for holding the plug to be mounted,
a joining device for sliding the hollow shaft onto the plug held in the holding device,
wherein the holding device is radially adjustable relative to an axis of the hollow shaft to compensate for an axial offset between the axis of the hollow shaft and an axis of the plug, and
wherein the joining device can be inclined to compensate for an inclined position of the axis of the hollow shaft and the axis of the plug, and
wherein the holding device includes a floatingly mounted plate, on which the plug to be mounted stands.

2. The device according to claim 1 , wherein the floatingly mounted plate is adjustably mounted in a radial direction relative to the hollow shaft via an air cushion or a ball bearing.

3. The device according to claim 2 , wherein the holding device further includes a baseplate, between which the air cushion or the ball bearing and the floatingly mounted plate is arranged.

4. The device according to claim 3 , wherein the holding device further includes a centring pin that engages through the baseplate and the floatingly mounted plate to centre the floatingly mounted plate with play.

5. The device according to claim 2 , wherein the holding device further includes a collar that encloses the ball bearing and, together with the floatingly mounted plate, forms a receptacle for the plug.

6. The device according to claim 4 , wherein the joining device is arranged above the holding device.

7. The device according to claim 1 , wherein the joining device can be inclined by up to 7.5°.

8. A method for joining a plug in a hollow shaft via a device, comprising:
providing a holding device for holding the plug and a joining device for sliding the hollow shaft onto the plug,
arranging the plug in the holding device,
positioning the hollow shaft substantially vertically above the plug,
pressing the joining device onto the hollow shaft from above to slide the hollow shaft over the plug and adjusting the holding device with the plug radially to the hollow shaft when an axial offset is present between an axis of the hollow shaft and an axis of the plug, and inclining the joining device when an inclined position is present between the axis of the hollow shaft and the axis of the plug.

9. The method according to claim 8 , wherein arranging the plug in the holding device includes disposing the plug on a floatingly mounted plate of the holding device that is adjustably mounted in a radial direction relative to the hollow shaft via an air cushion or a ball bearing.

10. The method according to claim 9 , further comprising receiving the plug in a receptacle formed by the floatingly mounted plate and a collar of the holding device that encloses the ball bearing.

11. The method according to claim 9 , wherein the joining device is inclined by up to 7.5° when the inclined position is present between the axis of the hollow shaft and the axis of the plug.

12. The device according to claim 3 , wherein the holding device further includes a collar that encloses the ball bearing and, together with the floatingly mounted plate, forms a receptacle for the plug.

13. The device according to claim 4 , wherein the holding device further includes a collar that encloses the ball bearing and, together with the floatingly mounted plate, forms a receptacle for the plug.

14. The device according to claim 5 , wherein the joining device is arranged above the holding device.

15. The device according to claim 6 , wherein the joining device can be inclined by up to 7.5°.

16. A device for mounting a plug in a hollow shaft, comprising:
a holding device for holding the plug to be mounted;
a joining device for sliding the hollow shaft onto the plug held in the holding device;
wherein the holding device is radially adjustable relative to an axis of the hollow shaft to compensate for an axial offset between the axis of the hollow shaft and an axis of the plug;
wherein the joining device can be inclined by up to 7.5° to compensate for an inclined position of the axis of the hollow shaft and the axis of the plug; and
wherein the holding device includes a floatingly mounted plate, on which the plug to be mounted stands.

17. The device according to claim 16 , wherein the floatingly mounted plate is adjustably mounted in a radial direction relative to the hollow shaft via an air cushion or a ball bearing.

18. The device according to claim 17 , wherein the holding device further includes a baseplate arranged between the air cushion or the ball bearing and the floatingly mounted plate.

19. The device according to claim 18 , wherein the holding device further includes a centring pin that engages through the baseplate and the floatingly mounted plate.

20. The device according to claim 19 , wherein the joining device is arranged above the holding device.
