    The invention relates to an eccentric bolt.
    With the help of eccentric bolts, components can be aligned relative to one another. Eccentric bolts known from practice have eccentric bolt sections which are positioned eccentrically to one another. A first eccentric bolt section interacts with a first component and a second eccentric bolt section with a second component. In the case of eccentric bolts known from practice, the eccentric bolt sections positioned eccentrically with respect to one another are each contoured to be circular in cross section. Eccentric bolts known from practice require special tools for handling and are typically project-dependent.
    DE 10 2014 222 445 A1 discloses an eccentric bolt with eccentric bolt sections which are round in cross section and positioned eccentrically to one another.
    Proceeding from this, the present invention seeks to create a novel eccentric bolt, with the help of which components can be easily and reliably aligned relative to one another. This object is achieved by an eccentric bolt according to claim 1. According to the invention, the first eccentric bolt section and the second eccentric bolt section are each angularly contoured in cross-section, with an angular cross-sectional contour of the first eccentric bolt section relative to an angular cross-sectional contour of the second eccentric bolt section in a first eccentric direction by a first amount and in a second eccentric direction perpendicular thereto by one of the first Amount deviating second amount is offset eccentrically.
    The invention proposes for the first time an eccentric bolt whose eccentric bolt sections are angularly contoured in cross section. The angularly contoured cross-sections of the eccentric bolt sections are offset from one another by different amounts in two eccentric directions running perpendicular to one another. With such an eccentric bolt, a simple and reliable alignment of components to one another can take place without the need for special tools. The eccentric bolt according to the invention is independent of the project and can be stored in bulk.
    According to an advantageous further development, the first eccentric bolt section and the second eccentric bolt section are each polygonal in cross section, preferably in the sense of a regular octagon. When the eccentric bolt sections are contoured as regular polygons, in particular as regular octagons, they can be used to align components with one another in a particularly advantageous manner.
    According to an advantageous development, a circle on which the corners of the cross-sectional contour of the first eccentric bolt section lie, and a circle on which the corners of the cross-sectional contour of the second eccentric bolt section lie, have different radii. This feature is particularly preferred for a simple and reliable alignment of the components with one another.
    According to an advantageous development, the eccentric bolt has a hole extending through the first eccentric bolt section and the second eccentric bolt section, via which the eccentric bolt can be fastened to one of the components to be aligned via a fastening screw extending through the bore, with the respective other component on Eccentric bolt can be suspended. The eccentric bolt can be fastened to one of the components to be aligned with one another via the fastening screw that interacts with this bore. The other component is suspended from the eccentric bolt.
    The invention further relates to an arrangement of a first component, a second component to be aligned relative to the first component and at least one eccentric pin according to the invention.
    Preferred developments of the invention emerge from the dependent claims and the following description. Embodiments of the invention are explained in more detail with reference to the drawing, without being restricted thereto. It shows:<tb> Fig. 1 <SEP> shows a cross section through an arrangement of a first component, a second component to be aligned relative to the first component, and an eccentric bolt according to the invention;<tb> Fig. 2 <SEP> a cross section offset by 90 ° compared to FIG. 1 through the arrangement of the first component, the second component to be aligned relative to the first component and the eccentric bolt according to the invention;<tb> Fig. 3 <SEP> the cross section III-III of FIG. 1;<tb> Fig. 4 <SEP> the cross section IV-IV of FIG. 1;<tb> Fig. 5 <SEP> a side view of an eccentric bolt according to the invention;<tb> Fig. 6 <SEP> a view of the eccentric bolt in the direction of the arrow VI in FIG. 5; and<tb> Fig. 7 <SEP> several different positions of the eccentric bolt.
    The present invention relates to an eccentric bolt for aligning components with one another.
    Furthermore, the invention relates to an arrangement of components to be aligned with one another and at least one eccentric bolt.
    1 to 4 show different cross sections through an arrangement of two components to be aligned with one another and an eccentric bolt according to the invention. 1 shows a first component 10, a second component 11 to be aligned relative to the first component 10 and an eccentric bolt 12 used for this alignment. The first component 10 can, for example, be a turbine housing of a turbo-engine and the second component 11 act as a built-in part, such as a guide vane carrier, a sealing element or the like. 5 and 6 show the eccentric bolt 12 in a single representation.
    The eccentric bolt 12 has two eccentric bolt sections 13, 14. The first eccentric bolt section 13 interacts with the first component 10 and the second eccentric bolt section 14 cooperates with the second component 11, the two eccentric bolt sections 13, 14 being positioned eccentrically to one another. As can best be seen from FIG. 6, the two eccentric bolt sections 13, 14 have an angular contour in cross section. A contour 15 of the first eccentric bolt section 13 and a contour 16 of the second eccentric bolt section 14 are each contoured in the sense of a polygon, namely in the preferred embodiment shown in the sense of a regular polygon, in particular a regular octagon. A regular polygon is to be understood as a polygon whose sides and angles are all the same.
    The octagonal cross-sectional contour 15 of the first eccentric bolt section 13 accordingly comprises eight corners 17 which are positioned on a first circle. The cross-sectional contour 16 of the second eccentric bolt section 14 also has eight corners 18 which are positioned on a second circle. The radii of these two circles are different. The radius of the circle on which the corners 18 of the octagon of the second eccentric bolt section 14 is positioned is smaller than the radius of the circle on which the corners 17 of the cross-sectional contour 15 of the first eccentric bolt section 13 are positioned.
    The cross-sectional contours 15, 16 of the two eccentric bolt sections 13, 14, which are contoured as regular octagons in the exemplary embodiment shown, are offset in two mutually perpendicular eccentric directions, specifically by different amounts. By rotating the eccentric bolt 12 by 45 ° in each case, the components 10, 11 can be aligned with one another, to be precise as shown in FIG. 7, in different steps. The rotation of the eccentric bolt 12 in 45 ° steps and the alignment of two components made possible by this in the direction of the arrow 19 shown in FIG. 7 relative to a zero line 20 in different gradations for each of the 45 ° steps results from the contouring of the Cross-sections of the eccentric bolt sections 13, 14 as regular octagons as well as the fact that these regular octagons are eccentrically offset from one another by different amounts in two eccentric directions running perpendicular to one another.
    1, 2, 5 and 6 it can also be seen that the eccentric bolt 12 has a bore 21 extending through both eccentric bolt sections 13, 14, a fastening screw 22 cooperating with the bore 21. As already stated, when the two components 10, 11 are aligned with one another with the aid of the eccentric bolt 12, the first eccentric bolt section 13 interacts with the first component 10 and the second eccentric bolt section 14 interacts with the second component 11, namely with corresponding grooves 23, 24 of the respective Component 10, 11. The grooves 23, 24 are designed as elongated holes.
    The groove 23 in the first component 10, which cooperates with the first eccentric bolt section 13 of the eccentric bolt 12, is designed such that it receives the first eccentric bolt section 13 without play or almost without play and in a second direction perpendicular thereto There is clear play between the first eccentric bolt section 13 and the groove 23 of the first component 10.
    In an analogous manner, the groove 24 of the second component 11 is contoured, the same accordingly takes the second eccentric bolt portion 14 of the eccentric bolt 12 play-free or almost play-free in the first direction, in the second direction perpendicular to this there is clear play between the second eccentric bolt section 14 of eccentric bolt 12 and the groove 24 of second component 11.
    The first direction, in which the grooves 23, 24 receive the respective eccentric bolt section 14 without play, runs in the direction in which the components 10, 11 are to be aligned relative to one another. The second direction in which the grooves 23, 24 receive the respective eccentric bolt section 14 with play runs perpendicular to the direction in which the components 10, 11 are to be aligned relative to one another. If the components 10, 11 are to be aligned in the horizontal direction, the first direction runs in the horizontal direction and the grooves 23, 24 are preferably arranged at a 6 o'clock position and / or 12 o'clock position of the components 10, 11 . If alignment is to take place in the vertical direction, the first direction runs in the vertical direction and the grooves 23, 24 are preferably arranged at a 3 o'clock position and / or 9 o'clock position of the components 10, 11.
    In order to align the two components 10, 11 with one another, in the embodiment shown in FIGS. 1 to 4, the eccentric bolt 12 is in one of the alignments shown in FIG. 7, that is in one of the 45 ° steps shown in FIG or 45 ° steps, mounted on the second component 11 via the fastening screw 22, the second eccentric bolt section 14 of the eccentric bolt 12 being received in the groove 24 of the second component 11. The two components are then loosely attached to one another, preferably in such a way that the second component 11 is loosely suspended from the first component 10 via the or each eccentric bolt 12 mounted on it, namely by the respective eccentric bolt 12 with its first section 13 is introduced into the corresponding groove 23 of the first component 10.
    In contrast to this, however, it is also possible to hang the first component 10 loosely on the or each eccentric bolt 12 attached to the second component 11, namely by inserting the first eccentric bolt section 13 into the corresponding recess or groove 23 of the first component 10 .
    In the exemplary embodiment shown in FIGS. 1 to 4, the fastening screw 22 extends, starting from the first eccentric bolt section 13, into the second eccentric bolt section 14 and into the second component 11. It is also possible that the fastening screw 22 extends in the opposite direction, starting from the second eccentric bolt section 14, into the first eccentric bolt section 13 and into the first component 10, in order to fasten the eccentric bolt 12 to the first component 10 and the second component 11 loosely to the second Suspend the eccentric bolt section 14 of the respective eccentric bolt 12.
    In the embodiment shown, in which the eccentric bolt sections 13, 14 of the eccentric bolt 12 are contoured as regular octagons which are eccentrically offset from one another in two mutually perpendicular eccentric directions, a particularly advantageous alignment of two components 10, 11 to one another can be realized . Then, if the regular octagons are offset by 0.11 mm in the first eccentric direction and by 0.5 mm in the second eccentric direction, the components can be moved stepwise by ± 0.11 mm, ± 0.276 mm, ± 0.431 mm and ± 0.5 mm, namely by rotating the eccentric bolt 12 in the 45 ° steps shown in FIG. 7. In Fig. 7, in the 0 ° position of the eccentric bolt 12 there is an alignment above the zero line 20 by -0.11 mm, in the 45 ° position of the same an alignment above the zero line 20 by +0.276 mm, in the 90 ° - Position of the same an alignment above the zero line 20 by +0.5 mm, in the 135 ° position of the same an alignment above the zero line 20 by +0.431 mm, in the 180 ° position of the same an alignment above the zero line 20 by +0, 11 mm, in the 225 ° position of the same an alignment above the zero line 20 by -0.276 mm, in the 270 ° position of the same an alignment above the zero line 20 by -0.5 mm, in the 315 ° position of the same one alignment above the zero line 20 by -0.431 mm.
    Below the zero line 20, the signs of the graduated alignments relative to the zero line 20 change in the respective positions of the eccentric bolt 12, which are graduated by 45 ° steps, while the amounts remain the same.
    The grooves 23, 24 are preferably designed in so-called H7 quality.
    When aligning two components 10, 11 to each other, it is sufficient to use a single such eccentric bolt 12, the alignment being carried out by choosing one of the positions of the eccentric bolt 12 shown in Fig. 7 relative to the zero line 20, so by a the orientations or positions of the eccentric bolt 12 shown in FIG. 7, which differ from one another in 45 ° steps.
