Abstract

The present invention relates to an arrangement, comprising a first turbomachine element with a first turbomachine element through-opening, a second turbomachine element, a sliding element with a sliding element through-opening that is arranged, at least in part, in the first turbomachine element through-opening, a sleeve that engages through the sliding element through-opening along a through-axis, and a fastening member that engages through the sleeve for fastening the sleeve to the second turbomachine element. Furthermore, the invention relates to a method for fastening the first turbomachine element to the second turbomachine element, a turbomachine with the above-mentioned arrangement, and use of this arrangement.

First claim

What is claimed is:

1. An arrangement, comprising:
a first turbomachine element with a first turbomachine element through-opening;
a second turbomachine element;
a sliding element with a sliding element through-opening that is arranged, at least in part, in the first turbomachine element through-opening;
a sleeve engaged through the sliding element through-opening along a through-axis; and
a fastening member, disposed through the sleeve, for fastening the sleeve to the second turbomachine element,
wherein the first turbomachine element through-opening has an elongated hole, in which the sliding element is guided in a displaceable manner along a displacement axis perpendicular to the through-axis and is guided in a form-fitting, displaceable manner.

2. The arrangement according to claim 1 , wherein the sliding element has a pair of flat contact faces for form-fitting guiding along the displacement axis, which are engaged with corresponding flat contact faces of the elongated hole.

3. The arrangement according to claim 1 , wherein the sliding element is mounted rotatably on the sleeve around the through-axis.

4. The arrangement according to claim 1 , wherein the fastening member clamps the sleeve against the second turbomachine element.

5. The arrangement according to claim 1 , wherein the first turbomachine element is displaceable relative to the sleeve or on the sliding element, such that the first turbomachine element is displaceable along the through-axis between the second turbomachine element and a stop, which is clamped by the fastening member against the sleeve and is connected to the fastening member so as to be releasable without destruction or the stop and the sleeve are integrally formed.

6. The arrangement according to claim 1 , wherein a form-fitting and/or force-fitting connection between the first turbomachine element and the second turbomachine element prevents any relative movement between the first turbomachine element and the second turbomachine element along a transverse axis perpendicular to the through-axis and perpendicular to the displacement axis.

7. The arrangement according to claim 1 , wherein the second turbomachine element has a second turbomachine element opening that is open on one side, to define a blind bore, or on both sides, to define a through-hole, in which the fastening member engages.

8. The arrangement according to claim 1 , wherein the fastening member is a bolt with a bolt head or a screw with a thread or a screw head with one or two nuts screwed onto the screw.

9. The arrangement according to claim 8 , wherein a force distribution element, which is inserted onto the fastening member, is arranged between the fastening member and the sleeve.

10. The arrangement according to claim 1 , wherein the arrangement is configured in a turbomachine.
