[0004] DESCRIPTION

[0005] Storage device for storing a load and machine arrangement with such a storage device

[0006] The invention relates to a bearing device for storing a load and a machine arrangement with a load-bearing element, at least one machine component and at least one such bearing device.

[0007] Depending on the use of sensitive loads, such as machine components, a bearing is required that meets high acoustic and shock requirements. This is particularly true when such loads are to be used at sea, for example in vessels, where they are sometimes exposed to extremely harsh conditions in heavy seas. This applies even more so to military applications, where additional shock loads can occur due to the effects of munitions – whether from recoil during active use or from the actual effect of the munitions during passive exposure. Simple bearings typically exhibit an unfavorable A / B frequency from a shock perspective, as well as insufficient displacement capability.While it is theoretically possible to use stiffer bearings to increase the tuning frequency, their increased stiffness results in particularly poor displacement properties, making them susceptible to failure under high shock loads. It is also theoretically possible to elastically mount machine components on a support frame, which in turn is elastically mounted on a foundation, thus providing a double support system; however, this type of mounting requires a large installation space, which is typically unavailable in ships. Therefore, a suitable mounting solution is needed in a confined space.

[0008] The invention is therefore based on the objective of providing a storage device for storing a load and a machine arrangement with a support element, at least one 2024P00022DE

[0009] 2

[0010] to create a machine component and at least one such storage device in which the aforementioned disadvantages are at least reduced, or preferably do not occur.

[0011] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims and of the preferred embodiments disclosed in the dependent claims and the description.

[0012] The problem is solved, in particular, in a first aspect, by creating a bearing device for supporting a load on a support element, which has a first elastic bearing element and a second elastic bearing element, wherein the first bearing element and the second bearing element are arranged one behind the other along a force application axis of a support force, wherein the bearing device has a first attachment point configured to fasten the bearing device to the support element, wherein the bearing device has a second attachment point configured to fasten the load to the bearing device, wherein the first attachment point is arranged along the force application axis between the first bearing element and the second bearing element, and wherein the second attachment point is arranged at a bearing end of the first bearing element facing away from the second bearing element.and wherein the first bearing element and the second bearing element are each connected to the second mounting point along the force application axis in a way that allows for movement in both directions. The bearing device proposed here advantageously provides a double elastic mounting, which allows the tuning frequency to be shifted upwards – to higher frequencies – to a position more favorable from a shock perspective, compared to a single mounting, while simultaneously maintaining a large degree of displacement of the bearing elements and eliminating the need for an additional support frame, thus enabling a compact, space-saving mounting. The arrangement of the two bearing elements one behind the other also results in a high elastic mass used for the mounting, thereby improving the acoustic damping properties.

[0013] In the context of this technical teaching, a load-bearing capacity is understood to mean a load to be supported, in particular a load sensitive to mechanical influences, preferably a machine component such as an internal combustion engine and / or an electric machine. However, the bearing device can also generally be used to support other 2024P00022DE

[0014] 3

[0015] Load-bearing capacity, such as that of electronic components, control units, or the like, can be used.

[0016] In the context of this technical teaching, a load-bearing element is understood to be, in particular, a structure on which the load is supported, that is, specifically, on which the load is attached or connected via the bearing device. Such a load-bearing element can be, for example, a foundation, a floor, in particular a floor slab, a ceiling or ceiling panel, a beam, or the like. In a preferred embodiment, the load-bearing element itself is not a separately supported support frame, but rather a direct part of a structure that is not itself supported. Instead, the load-bearing element is preferably rigidly connected to another body, such as a building or vessel, or is part of that body. In particular, it is advantageous to avoid the use of a separately supported support frame; that is, both the bearing device and the machine arrangement described below are free of such a support frame.

[0017] In the context of this technical teaching, the force application axis is understood to be the intended principal axis of force application. This does not preclude the possibility that forces may also be applied to or absorbed by the bearing device that are oriented obliquely or perpendicular to the force application axis. In particular, the force application axis is the axis along which the bearing device exhibits its greatest displacement capability, i.e., the greatest displacement path before failure. Preferably, the force application axis is an axis that, when the bearing device is mounted on a machine assembly as intended, points in the geodetic vertical direction or direction of gravity, i.e., a vertical axis as intended.

[0018] The fact that the first bearing element and the second bearing element are arranged one behind the other along the force application axis means, in the context of the present technical teaching, in particular that the two bearing elements are arranged parallel to each other, especially antiparallel, in terms of circuit technology.

[0019] The fact that the first fastening point is arranged along the force application axis between the first bearing element and the second bearing element means, in particular, that the support element is arranged between the first bearing element and the second bearing element 2024P00022DE

[0020] 4. In particular, the bearing element is arranged between the first bearing element and the second bearing element. Preferably, both the first bearing element and the second bearing element are directly supported by the support element, or in other words: both the first bearing element and the second bearing element are attached to the support element.

[0021] Preferably, in a intended arrangement of the bearing elements on the support element, the first bearing element is arranged on a first side of the support element, in particular geodesically above the support element, with the second bearing element being arranged on a second side opposite the first side in the direction of the force application axis, in particular geodesically below the support element. This advantageously contributes to a space-saving arrangement of the bearing device on the support element. For example, the second bearing element can be recessed into a recess or indentation, or it can project into a space arranged below the support element, especially if the support element is designed as a floor or a ceiling.

[0022] The fact that the second fastening point is located at the bearing end of the first bearing element that faces away from the second bearing element means, in particular, that the load-bearing capacity can be arranged on the first bearing element – ​​along the force application axis opposite the second bearing element – ​​and is specifically intended to be arranged on the first bearing element. The load-bearing capacity is preferably attached to the first bearing element.

[0023] The fact that the first and second bearing elements are connected to the second mounting point along the force application axis in a way that allows movement in both directions means, in particular, that the first and second bearing elements are mechanically connected to the second mounting point in such a way that when the second mounting point shifts, for example due to compression or rebound of the load, both bearing elements are moved along with it. This, in turn, means that one of the two bearing elements is not merely relieved of the load, but is actively moved in the corresponding direction of displacement. Preferably, both bearing elements are rigidly connected to the second mounting point—and, in particular, to each other. While, during displacement along the force application axis, one bearing element is compressed, i.e., subjected to pressure 2024P00022DE

[0024] When the bearing element is loaded at point 5, the other bearing element is not only relieved of the load, but is actively displaced in the direction of extension, in particular - depending on any preload and the deflection - stretched, i.e., subjected to tensile stress.

[0025] According to a further development of the invention, the first bearing element and the second bearing element are preloaded against each other along the force application axis. Advantageously, the stiffness of the bearing device can be preset in this way.

[0026] According to a further development of the invention, at least one bearing element, selected from the first and second bearing elements, has an asymmetric characteristic curve. Advantageously, the at least one bearing element exhibiting the asymmetric characteristic curve behaves differently under tensile and compressive loads. It can be specifically tailored to the expected loads. The asymmetric characteristic curve can be achieved, in particular, by a suitable shape of an elastic spring element within the respective bearing element.

[0027] In the context of this technical teaching, a characteristic curve is understood to be, in particular, a stiffness characteristic curve, that is, a curve that can be represented in a diagram in which the restoring force is plotted against the displacement. Specifically, in the diagram, the displacement is plotted on the abscissa (x-axis) and the restoring force on the ordinate (y-axis).

[0028] In the context of this technical teaching, an asymmetric characteristic curve is understood to be, in particular, a characteristic curve whose slope for tensile load differs from the slope for compressive load. Specifically, the characteristic curve in the aforementioned diagram exhibits an asymmetry with respect to the origin, where the origin lies at zero displacement and zero restoring force, i.e., at the zero point of the abscissa and the ordinate, respectively.

[0029] In one embodiment, the at least one bearing element with the asymmetric characteristic curve exhibits lower stiffness under tensile load than under compressive load; that is, the characteristic curve is steeper (progressive) for compressive load – meaning it has a greater slope – than for tensile load (degressive). 2024P00022DE

[0030] 6

[0031] In one embodiment, the first bearing element and the second bearing element each have an asymmetric characteristic curve. Preferably, the first bearing element and the second bearing element have identical asymmetric characteristic curves.

[0032] In another embodiment, only the first bearing element has an asymmetric characteristic curve; in particular, the second bearing element has a symmetric characteristic curve. Alternatively, only the second bearing element has an asymmetric characteristic curve; in particular, the first bearing element has a symmetric characteristic curve.

[0033] According to a further development of the invention, the second bearing element is arranged in reverse along the force application axis with respect to the first bearing element. This advantageously allows for particularly favorable properties to be obtained for the bearing device.

[0034] The fact that the second bearing element is arranged in reverse with respect to the first bearing element along the force application axis means, in particular, that the second bearing element is arranged reversed or mirrored compared to the first bearing element.

[0035] According to a further development of the invention, the first bearing element and the second bearing element are designed identically. This represents a simple yet advantageous embodiment of the bearing device.

[0036] In one embodiment, the first bearing element and the second bearing element have the same – that is, identical – characteristic curve, preferably an asymmetrical one. In particular, if the second bearing element is arranged inversely to the first bearing element along the force application axis, the bearing device advantageously has an overall symmetrical characteristic curve.

[0037] The bearing device with two identically designed bearing elements, especially with identical characteristic curves, offers an advantage over a single bearing element: a factor of 2 increase in the off-frequency response – this applies at least to a very good approximation even with asymmetry of the characteristic curves, since the deflections relevant with regard to the off-frequency response are small and thus the differences in the various branches of the 2024P00022DE

[0038] 7

[0039] The characteristic curve, that is, with regard to tensile and compressive loads, is negligible, especially when the bearing elements in the bearing device are preloaded.

[0040] Furthermore, the arrangement of two bearing elements – compared to a single bearing element with the same tuning frequency – results in a significantly increased displacement capacity, since a single bearing element used alone would have to be designed to be considerably stiffer than the two combined bearing elements. Consequently, it could only be displaced over a significantly smaller distance without failing, and especially without tearing. In this case, in particular, the bearing assembly exhibits especially favorable shock characteristics.

[0041] Due to the doubling of the preferably identically designed bearing elements compared to a single bearing element, there is also a relevant increase in the elastic mass, resulting in significant improvements in the acoustic properties, in particular an increase in insulation by a factor of 2, especially transmission insulation.

[0042] In one embodiment, the first bearing element comprises a first elastic spring element, and the second bearing element comprises a second elastic spring element. This advantageously represents a simple yet functional design for achieving the elastic properties of the bearing elements. The two spring elements preferably have identical, and in particular, asymmetrical, characteristic curves.

[0043] According to a further development of the invention, the first bearing element comprises the first elastic spring element, which is attached on one side to a first base plate and on the other side to a first drive element. The second bearing element comprises the second elastic spring element, which is attached on one side to a second base plate and on the other side to a second drive element. The first attachment point is formed between the first base plate and the second base plate, and the second attachment point is formed on the first drive element. The first drive element and the second drive element are movably connected to each other along the force application axis. This advantageously represents a simple yet functional design, particularly for achieving the movable connection between the two bearing elements. 2024P00022DE

[0045] The first elastic spring element is preferably designed as a first elastomer or comprises a first elastomeric material. Alternatively or additionally, the second elastic spring element is designed as a second elastomer or comprises a second elastomeric material. In a preferred embodiment, the elastomers or elastomeric materials of the first and second elastic spring elements are identical. Furthermore, the first and second elastic spring elements preferably have identical shapes.

[0046] The first base plate is preferably designed as a rigid plate, preferably made of a metal, in particular steel.

Alternatively or additionally, the second drive element is preferably rigid, preferably made of a metal, particularly steel.

[0048] In one embodiment, the first elastic spring element is vulcanized to the first drive element. Alternatively or additionally, the second elastic spring element is vulcanized to the second drive element.

[0049] Alternatively or additionally, the first elastic spring element is vulcanized to the first base plate. Alternatively or additionally, the second elastic spring element is vulcanized to the second base plate.

[0050] Preferably, the first and second drive elements are rigidly connected to each other along the force application axis, preferably by means of a connecting rod that passes through an opening in the support element. The connecting rod can, for example, be screwed to the first drive element and / or to the second drive element. 2024P00022DE

[0051] 9

[0052] The problem is also solved in a second aspect by creating a machine arrangement comprising a support element, at least one machine component, and at least one bearing device according to the invention or a bearing device according to one or more of the embodiments described above, wherein the at least one bearing device is attached to the support element at its first attachment point, and wherein the at least one machine component is attached to the second attachment point of the at least one bearing device. In connection with the machine arrangement, the advantages that have already been explained in connection with the bearing device become particularly apparent.

[0053] As previously stated, the force application axis in the machine arrangement preferably points in a geodesically vertical direction, i.e., upwards. The second bearing element is preferably arranged geodesically below the support element, and the first bearing element is arranged geodesically above the support element. Accordingly, the at least one machine component can be geodesically attached above the first bearing element at the second mounting point and thus supported on the support element by means of the bearing device.

[0054] According to a further development of the invention, the supporting element is a foundation or a floor of a vessel. This particularly realizes the advantages already mentioned.

[0055] In one embodiment, the supporting element is a base plate of a ship.

[0056] Alternatively or additionally, the supporting element is a ship's foundation of a vessel.

[0057] According to a further development of the invention, it is provided that the at least one machine component comprises an internal combustion engine.

[0058] In one embodiment, the at least one machine component is designed as a combination of an internal combustion engine and an electric machine. In particular, it is possible that the internal combustion engine is a first machine component and the electric machine is a second machine component. Alternatively, the internal combustion engine and 2024P00022DE

[0059] 10. The internal combustion engine and the electric machine together form a machine component. The internal combustion engine is preferably coupled to the electric machine, in particular such that the internal combustion engine can drive the electric machine, the electric machine being configured to act as a generator. Such a combination of an internal combustion engine and an electric machine is also called a genset.

[0060] According to a further development of the invention, the at least one machine component is connected to the support element via a plurality of bearing devices than the at least one bearing device. Advantageously, larger or multiple machine components can also be supported in this way using the bearing device.

[0061] The at least one machine component is mechanically connected to the support element, in particular via the bearing device, and especially attached to it. In particular, the at least one machine component is mounted on the support element by means of the plurality of bearing devices.

[0062] The invention will be explained in more detail below with reference to the drawing. The drawing shows:

[0063] Figure 1 shows a schematic representation of an embodiment of a machine arrangement with an embodiment of a storage device;

[0064] Figure 2 shows a schematic detail of the storage device according to Figure 1;

[0066] Figure 4 schematic representations to explain the circuit arrangement and function of the bearing elements of the exemplary embodiment of the bearing device according to Figures 1 and 2.

[0067] Fig. 1 shows a schematic representation of an embodiment of a machine arrangement 1 with an embodiment of a bearing device 3, specifically two bearing devices 3.

[0068] The machine arrangement 1 comprises a support element 5, at least one machine component 7, and the two bearing devices 3. The machine arrangement 1 can have more than two 2024P00022DE

[0069] 11

[0070] Bearing devices 3, but also only one bearing device 3, in particular depending on the size of the at least one machine component 7.

[0071] The bearing devices 3 are preferably designed identically, so that in the following reference is made only to one of the bearing devices 3, whereby what has been described applies in particular to both bearing devices 3.

[0072] The bearing device 3 comprises a first elastic bearing element 9 and a second elastic bearing element 11, which are arranged one behind the other along a force application axis A of a bearing force. The bearing device has a first mounting point 13 at which the bearing device 3 is attached to the support element 5. The bearing device 3 has a second mounting point 15, shown in Figure 2, at which the at least one machine component 7 is attached to the bearing device 3 as a load. The first mounting point 13 is arranged along the force application axis A between the first bearing element 9 and the second bearing element 11, and the second mounting point 15 is arranged at a bearing end 17 of the first bearing element 9 facing away from the second bearing element 11.The first bearing element 9 and the second bearing element 11 are each connected to the second fastening point 15 along the force application axis A in a way that allows them to be moved in both directions.

[0073] In machine arrangement 1, the force application axis A preferably points in a geodesically vertical direction, i.e., upwards. The second bearing element 11 is then arranged geodesically below the support element 5, and the first bearing element 9 is arranged geodesically above the support element 5. Accordingly, the at least one machine component 7 is geodesically attached above the first bearing element 9 at the second mounting point 15 and is thus supported on—and in particular, mounted on—the support element 5 by means of the bearing device 3.

[0074] The supporting element 5 is preferably a foundation or a base, in particular a base plate or ship's foundation of a vessel 19, especially a military vessel 19, for example a cruiser, a frigate, a minesweeper or a submarine. 2024P00022DE

[0075] 12

[0076] The at least one machine component 7 preferably comprises an internal combustion engine 21 as a first machine component 7.1 and an electric machine 23 as a second machine component 7.2. The internal combustion engine 21 is preferably connected to the electric machine 23 in a drive-related manner, in particular such that the internal combustion engine 21 can drive the electric machine 23, wherein the electric machine 23 is configured to act as a generator.

[0077] Preferably, the at least one machine component 7 is connected to the support element 5 via a plurality of such - in particular identically designed - bearing devices 3, in particular fastened, in particular supported.

[0078] Fig. 2 shows a schematic detail representation of the bearing device 3 according to Figure 1.

[0079] Identical and functionally equivalent elements are provided with the same reference symbols in all figures, so that reference is made to the preceding description in each case.

[0080] Preferably, the first bearing element 9 and the second bearing element 11 are pre-tensioned against each other along the force application axis A.

[0081] Furthermore, preferably at least one bearing element 9, 11, selected from the first bearing element 9 and the second bearing element 11, has an asymmetric characteristic curve (see Figure 3). The asymmetric characteristic curve is preferably realized by a suitable shaping of an elastic spring element 25 of the respective bearing element 9, 11.

[0082] In particular, in the embodiment shown here, the second bearing element 11 is arranged in reverse – that is, reversed or mirrored on a plane on which the force application axis A is perpendicular – with respect to the first bearing element 9.

[0083] Furthermore, the first bearing element 9 and the second bearing element 11 are preferably designed identically. In particular, the first bearing element 9 and the second bearing element 11 have the same, preferably asymmetric, characteristic curve. 2024P00022DE

[0084] 13

[0085] The first bearing element 9 preferably comprises a first elastic spring element 25.1, which is attached at one end to a first base plate 27.1 and at the other end to a first drive element 29.1. The second bearing element 11 comprises a second elastic spring element 25.2, which is attached at one end to a second base plate 27.2 and at the other end to a second drive element 29.2. The first attachment point 13 is preferably formed between the first base plate 27.1 and the second base plate 27.2, and the second attachment point 15 is formed on the first drive element 29.1. The first drive element 29.1 and the second drive element 29.2 are connected to each other along the force application axis A – preferably rigidly – ​​preferably by means of a connecting rod 31 that extends through an opening 33 in the support element 5.In the embodiment shown here, the connecting rod 31 is screwed to the first drive element 29.1 and to the second drive element 29.2.

[0086] The first elastic spring element 25.1 and the second elastic spring element 25.2 are preferably identical, designed as elastomers, or they comprise an elastomeric material. They also preferably have identical shapes.

[0087] The first base plate 27.1 and the second base plate 27.2 are preferably identical, designed as rigid plates, preferably made of a metal, in particular steel. They also preferably have a cup- or basket-shaped structure 35 in which the respective spring element 25 is arranged and to which it is preferably vulcanized.

[0088] The first drive element 29.1 and the second drive element 29.2 are preferably identical and rigidly designed, preferably made of a metal, in particular steel, preferably with identical shape.

[0089] Preferably, the first elastic spring element 25.1 is vulcanized to the first drive element 29.1, and the second elastic spring element 25.2 is vulcanized to the second drive element 29.2. 2024P00022DE

[0090] 14

[0091] Alternatively or additionally, the first elastic spring element 25.1 is vulcanized to the first base plate 27.1. Alternatively or additionally, the second elastic spring element 25.2 is vulcanized to the second base plate 27.2.

[0092] Fig. 3 shows a characteristic curve diagram to explain the functioning of the exemplary embodiment of the bearing device 3 according to Figures 1 and 2.

[0093] The diagram is defined by the displacement in arbitrary units on the abscissa (x-axis) and the restoring force in arbitrary units on the ordinate (y-axis). A positive displacement corresponds to a tensile load, and a negative displacement corresponds to a compressive load.

[0094] The first curve, shown as a dashed line, is the characteristic curve for one of the bearing elements 9, 11 in sole use - preferably the characteristic curve for the other bearing element 11, 9 is identical, so that the characteristic curve shown here applies to both bearing elements 9, 11, each individually.

[0095] It becomes clear that the characteristic curve is asymmetrical, with a lower slope for tensile loads than for compressive loads.

[0096] The first bearing element 9 and the second bearing element 11 therefore preferably have identical asymmetric characteristic curves.

[0097] The second, solid curve represents the characteristic curve for the entire bearing assembly 3, that is, for the combination of the two bearing elements 9 and 11. Due to their inverse arrangement relative to each other and the identical individual characteristic curves, this second curve is symmetrical about the origin. The respective restoring force at each point of deflection is the sum of the restoring force when one bearing element 9, 11 is subjected to tension and the restoring force when the other bearing element 9, 11 is subjected to compression at the same deflection. 2024P00022DE

[0098] 15

[0099] Fig. 4 shows two schematic representations to explain the circuit arrangement and function of the bearing elements 9, 11 of the bearing device 3 according to Figures 1 and 2, quasi in the form of mechanical equivalent circuit diagrams.

[0100] In a) and b), different mechanical equivalent circuit diagrams are shown, which differ in terms of spatial arrangement but are the same in terms of the respective function and circuit arrangement shown.

[0101] In a), the first bearing element 9 and the second bearing element 11 are arranged spatially one behind the other along the force application axis, the orientation of which is represented here by an arrow P indicating the direction of the load in the static case – or the direction of movement in the dynamic case – as the bearing elements 9, 11 are actually arranged in the embodiment shown in Figures 1 and 2. Specifically, the two elastic spring elements 25.1, 25.2 associated with the bearing elements 9, 11 are represented by corresponding spring symbols.

[0102] The connecting rod 31 is shown to the side of the elastic spring elements 25.1, 25.2 for better illustration of its function.

[0103] The elastic spring elements 25.1, 25.2 are each attached to the support element 5 with their mutually facing ends, which form the first attachment point 13, wherein the mutually opposite ends of the elastic spring elements 25.1, 25.2 are rigidly connected to each associated end of the two opposite ends of the connecting rod 31.

[0104] If the second mounting point 15 is moved downwards in the plane of the figure, the first elastic spring element 25.1 is compressed, and the second elastic spring element 25.2 is stretched – carried along by the rigid connecting rod 31. Conversely, if the second mounting point 15 is moved upwards in the plane of the figure, the first elastic spring element 25.1 is stretched, and the second elastic spring element 25.2 is compressed – again carried along by the rigid connecting rod 31.

[0105] Thus, it becomes clear that the two elastic spring elements 25.1, 25.2, and consequently the two bearing elements 9, 11, are arranged antiparallel to each other in terms of circuit design. 2024P00022DE

[0106] 16

[0107] The parallelism – or more precisely, the anti-parallelism – of the circuit is also evident insofar as, when the second mounting point 15 is deflected by a certain distance d from its rest position, each of the elastic spring elements 25.1, 25.2 is also deflected by this distance d from its rest position – which may be pre-tensioned. In contrast, with a hypothetical circuit arrangement of the elastic spring elements 25.1, 25.2 in series, each of the elastic spring elements 25.1, 25.2 would only be deflected by half the distance dH, with the total deflection of the second mounting point 15 by the distance d being the sum of the two (partial) deflections of the elastic spring elements 25.1, 25.2.

[0108] In b), the two elastic spring elements 25.1, 25.2 – unlike in the embodiment according to Figures 1 and 2 – are also arranged spatially parallel to each other; the spatial arrangement in b) thus corresponds to the circuit arrangement, the circuit arrangement being otherwise identical to the circuit arrangement explained in connection with the illustration in a), and thus also identical to the circuit arrangement in the embodiment according to Figures 1 and 2.

[0109] Here too, in part b), if the second mounting point 15 is moved downwards in the plane of the figure, the first elastic spring element 25.1 is compressed, and the second elastic spring element 25.2 is stretched – carried along by the rigid connecting rod 31. Conversely, if the second mounting point 15 is moved upwards in the plane of the figure, the first elastic spring element 25.1 is stretched, and the second elastic spring element 25.2 is compressed – again carried along by the rigid connecting rod 31.

[0110] Furthermore, a comparison of the two representations in a) and b) shows that the spatial arrangement in a) - especially in terms of width - is more space-saving, particularly since one of the two elastic spring elements 25.1, 25.2 can be arranged below the support element 5.
