Description

Technical Field

[0001] The invention relates to a vibration absorber and a vibration transmission system. Background Art

[0002] Vibration absorbers are known in the prior art. For example, they can be used in vibration transmission systems, such as linear or circular vibrators of vibration systems. The purpose of vibration absorbers is to reduce the natural frequency of the vibration absorbers, increase their load capacity and improve their stability. Summary of the invention

[0003] The object of the invention is to provide an improved vibration absorber and an improved vibration transmission system. This problem is solved by a vibration absorber and a vibration transmission system having the features described in the independent claims. Advantageous further developments are given in the dependent claims.

[0004] The vibration damper of the present invention has four torsion elements. Each torsion element has an inner part, an outer part and at least one elastic element. The inner part is located in the outer part. The elastic element is located between the inner part and the outer part and supports the inner part relative to the outer part, so that when the inner part and the outer part are deflected relative to each other, a restoring force is generated between the inner part and the outer part. The torsion spring elements are located one above the other relative to a first direction. The second torsion spring element is located above the first torsion spring element. The third torsion spring element is located above the second torsion spring element. The fourth torsion spring element is located above the third torsion spring element. The outer part of the first torsion spring element is configured for rigid connection of the vibration damper. The inner part of the first torsion spring element is rigidly connected to the inner part of the third torsion spring element. The second torsion spring element is rigidly connected to the third torsion spring element. The inner part of the second torsion spring element is rigidly connected to the inner part of the fourth torsion element. The outer part of the fourth torsion element is configured for rigid connection of the vibration damper.

[0005] The first torsion spring element is connected to the third torsion spring element via the first lever element, and the second torsion spring element is connected to the fourth torsion spring element via the second lever element, and the torsion spring elements are connected to each other in a staggered manner. Compared with an arrangement in which the first torsion spring element is connected to the second torsion spring element via the first lever element and the third torsion spring element is connected to the fourth torsion spring element via the second lever element, the height of the shock absorber measured along the first direction is reduced. Advantageously, an object supported in a spring-mounted manner, for example a vibrating mass in a vibration transmission system, can be supported thereby so that the center of gravity is particularly close to a base to which the vibration absorber can be connected. A system with such a vibration absorber is thus more stable and safer in operation.

[0006] At the same time, such a shock absorber allows the use of a longer lever element at a comparable shock absorber height. This allows the natural frequency of the shock absorber to be particularly low, which reduces the wear of the shock absorber in the operation of a vibrating system which is damped by the shock absorber. The greater the spring deflection, the lower the natural frequency, which ensures a better damping effect. The insulating effect produced by the vibrating element is also greater.

[0007] On the other hand, the staggered connection of the torsion spring element and the lever element makes it possible to expand the angle formed by the lever element when the height of the shock absorber is consistent, thereby improving the load-bearing capacity of the shock absorber.

[0008] In one embodiment, the torsion spring elements are rigidly connected to each other via the lever element. The first lever element and the second lever element are located on opposite sides of the torsion spring element along a longitudinal direction extending perpendicularly to the first direction. Advantageously, this arrangement enables the torsion spring elements to be connected to the lever element ( Figure 2 ).

[0009] In one embodiment, the torsion spring elements are rigidly connected to each other via the lever element. The first lever element and the second lever element are located on one side of the torsion spring element along a longitudinal direction extending perpendicularly to the first direction. Advantageously, this arrangement allows a simple arrangement of the elastic element between the inner part and the outer part, since the torsion spring element is accessible on the side facing away from the lever element ( Figure 1 ).

[0010] In one embodiment, the lever element is designed in an angled and / or curved manner. Advantageously, this can reduce the height of the vibration absorber measured in a first direction, so that the vibration absorber is configured more robustly and can withstand greater stresses when used, for example, in a vibration transmission system. This can reduce the distance of the center of gravity of the vibration mass mounted on the spring relative to the base ( Figure 3 ).

[0011] In one embodiment, the lever elements are arranged to engage with each other. Advantageously, this allows the lever element to be arranged on one side relative to the torsion element ( Figure 4 ).

[0012] In one embodiment, the torsion spring element is arranged symmetrically with respect to a plane extending perpendicularly to the first direction. Advantageously, in the event of a force, the stress itself is evenly distributed on the torsion spring element, so that the vibration damper can be used particularly effectively.

[0013] In one embodiment, each outer part of the torsion spring element has a hollow polygonal profile. Each inner part of the torsion spring element has a polygonal profile. Accordingly, the inner part is arranged in the outer part of the torsion spring element so that the outer edges of the inner part are arranged to face the inner surface of the outer part respectively. Each torsion spring element has a plurality of elastic elements arranged between the inner part and the outer part. These elastic elements are respectively adjacent to the outer surface of the inner part and adjacent to the inner surface and / or inner edge of the outer part. The vibration transmission system comprises a vibration block and a plurality of vibration absorbers as described in one of the above embodiments. Each vibration absorber can be connected to the vibration block and the base. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The design concept of the shock absorber will be described in more detail below with reference to the accompanying drawings. Figure 1 Two different perspective views of a prior art shock absorber are shown; Figure 2 Two different perspective views of the shock absorber of the first embodiment are shown; Figure 3 Two different perspective views of the shock absorber showing a second embodiment; Figure 4 two different perspective views showing the shock absorber of a third embodiment; and Figure 5 A side view of a vibration transmission system with a vibration absorber is shown. DETAILED DESCRIPTION

[0015] Figure 1 Two different perspective views of a prior art vibration absorber 100 are schematically shown. The vibration absorber 100 may also be referred to as a vibration element.

[0016] The vibration damper 100 has, for example, four torsion spring elements 101. Each torsion spring element 101 has an inner part 102 and an outer part 103. The outer part 103 has, for example, a metal material, for example, the outer part 103 can be configured as a cast steel component. In addition, the outer part 103 can be made of at least one plastic and / or at least one metal material. However, the outer part 103 can also be made of other materials or other material combinations.

[0017] according to Figure 1In the exemplary embodiment shown, the outer part 103 has a hollow square profile with open ends along the longitudinal direction 104. For example, the longitudinal edge 105 of the outer part 103 is configured in a rounded manner parallel to the longitudinal direction 104 on the inner side (inner edge) and / or on the outer side (outer edge). In other embodiments, the outer part 103 is implemented, for example, as a hollow polygonal profile with a polygonal, n-gonal cross section, or as a hollow body with a circular, elliptical or different shaped cross section, wherein the longitudinal edge 105 of the outer part 103 can be rounded on the inner side and / or the outer side. In a preferred embodiment, the longitudinal edge 105 of the outer part 103 has a length of up to 500 mm, and the edge transverse to the longitudinal direction 104 has a length of up to 100 mm. However, the size of the outer part 103 is not limited to the above-mentioned numerical range.

[0018] The inner part 102 also has a hollow square profile with open ends along the longitudinal direction 104. The longitudinal edges of the inner part 102 are also configured in a rounded manner, for example, on the inner side (inner edge) and / or on the outer side (outer edge) parallel to the longitudinal direction 104. In other embodiments, the inner part 102 can also be implemented as a hollow polygonal profile with a polygonal, n-angle cross section, or as a hollow body with a circular, elliptical or different cross section, wherein the longitudinal edges of the inner part 102 can be rounded on the inner side and / or the outer side. The outer part 103 and the inner part 102 can have the same material or different materials. In one embodiment, the inner part 102 can be, for example, a metal material. However, the inner part 102 can adopt different materials or different material combinations.

[0019] The inner part 102 is arranged in the outer part 103. Here, the end of the inner part 102 protrudes from the outer part 103, for example in the longitudinal direction 104, so that the fixing of parts that do not belong to the shock absorber 100, for example, elements of a machine that requires spring mounting or requires vibration reduction, is simplified. The inner part 102 has a through hole 106, for example, which is circular or angular and extends through the inner part 102 parallel to the longitudinal direction 104. The through hole 106 is used to connect the inner part 102 to a connecting element 108, for example to a shaft, a rod or a bolt. Optionally, the through hole 106 can be provided with an internal thread or other fastening structure at least in its opening area.

[0020] In other embodiments, a blind hole, for example, may be provided on the end face of the inner part 102 instead of the through hole 106, and the blind hole may be provided with a thread or other fastening structure accordingly. In other embodiments, instead of providing a circular through hole 106 or a circular blind hole, a through hole or a blind hole of a different shape may be provided, for example, a hole with a polygonal cross section, and a thread or other fastening structure may be provided in the hole accordingly. The inner part 102 may also have a plurality of mutually parallel through holes 106, blind holes or other through holes 106 and blind holes for connecting to one or more connecting elements 108.

[0021] The outer part 103 and the inner part 102 have cross-sectional shapes corresponding to each other in terms of their geometric shapes, for example, square profiles, respectively. In other embodiments, the outer part 103 and the inner part 102 may also have other shapes, in particular shapes different from each other. For example, the inner part 102 has a triangular profile. The outer part 103 may also have a triangular profile, for example. However, the outer part 103 may also have a circular cross section. The inner part 102 is arranged in the outer part 103 so that the outer edge of the inner part 102 is arranged to face the inner surface of the outer part 103.

[0022] Each torsion spring element 101 has a plurality of elastic elements 107 arranged between an inner part 102 and an outer part 103. The elastic elements 107 are respectively adjacent to the outer surface of the inner part 102 and adjacent to the inner surface and / or inner edge of the outer part 103. The inner part 102 is arranged in the outer part 103 so that the cavity 115 formed between the inner part 102 and the outer part 103 has a substantially triangular cross section in the present geometry perpendicular to the longitudinal direction 104. Due to the present geometry of the inner part 102 and the outer part 103, the torsion spring element 101 has, for example, four cavities 115 in total.

[0023] The elastic element 107 is arranged in the cavity 115. Advantageously, the number of the elastic elements 107 corresponds to the number of the cavities 115. The elastic element 107 preferably supports the inner part 102 in a central position of the outer part 103, i.e., the inner part 102 and the outer part 103 are arranged coaxially along the longitudinal direction 104. In other embodiments, the inner part 102 is supported eccentrically in the outer part 103, i.e., the inner part 102 and the outer part 103 are arranged biaxially with respect to the longitudinal direction 104.

[0024] The elastic element 107 of the torsion spring element 101 can be inserted into the cavity 115, wherein the elastic element 107 is compressed. The elastic element 107 can be, for example, rubber or other elastic materials. The elastic element can also be called an elastic insert.

[0025] Before the elastic elements 107 are inserted into the outer part 103, they may also initially be formed like a cylinder. For example, the elastic elements 107 extend over the entire length of the outer part 103 with respect to the longitudinal direction 104, but this is not absolutely necessary. A plurality of elastic elements 107 may also be arranged one after another with respect to the longitudinal direction 104.

[0026] The inner part 102 is supported relative to the outer part 103 by the elastic element 107 so that in the case of a deflection caused by a rotation of the inner part 102 and the outer part 103 relative to each other, in particular an azimuthal rotation relative to the longitudinal direction 104, and / or in the case of a linear displacement of the outer part 103 relative to the inner part 102 along and / or transversely to the longitudinal direction 104, i.e. in the case of an axial and / or radial load, a restoring force is generated between the inner part 102 and the outer part 103. By selecting suitable materials for the outer part 103, the inner part 102 and the elastic element 107 and / or by selecting suitable geometries for the outer part 103, the inner part 102 and the elastic element 107, the restoring force-deflection curve and the hysteresis of the torsion spring element 101 can be adapted to the respective application.

[0027] The torsion spring elements 101 are arranged one above the other with respect to a first direction extending perpendicularly to the longitudinal direction 104. The second torsion spring element 111 is located above the first torsion spring element 110. The third torsion spring element 112 is located above the second torsion spring element 111. The fourth torsion spring element 113 is located above the third torsion spring element 112. The second torsion spring element 111 is rigidly connected to the third torsion spring element 112.

[0028] The second torsion spring element 111 and the third torsion spring element 112 share the same outer part 114, and the second torsion spring element 111 and the third torsion spring element 112 are rigidly connected to each other via the outer part 114. The outer part 114 has two receiving spaces for receiving the inner part 102 and the at least one elastic element 107, respectively. Alternatively, it is conceivable that the second and third torsion spring elements 111, 112 each have their own outer part 103, which are rigidly connected to each other. The receiving spaces are separated from each other by a partition wall 116 of the outer part 114, however, this partition wall 116 is not absolutely necessary. The inner parts 102 of the second torsion spring element 111 and the third torsion spring element 112 are thus connected in series in a first direction and therefore perpendicular to the longitudinal direction 104.

[0029] Furthermore, the shock absorber 100 has two lever elements 109. For example, the lever elements 109 are made of metal. The lever elements 109 can be manufactured, for example, by casting or by a printing process. The lever elements 109 are rigidly connected to the connecting element 108, for example, they can be welded to the connecting element 108. The connecting element 108 is arranged to extend perpendicularly to the lever elements 109. The lever elements 109 can be constructed, for example, in a straight line, however, lever elements 109 of different shapes are also explained in this specification.

[0030] The lever element 109 is arranged transversely at the open end of the torsion spring element 101 and connected to the torsion spring element 101 through the connecting element 108. Each lever element 109 connects the inner parts 102 of two torsion spring elements 101 together. The first lever element 117 connects the first torsion spring element 110 to the second torsion spring element 111. The second lever element 118 connects the third torsion spring element 112 and the fourth torsion spring element 113.

[0031] For example, the vibration damper 100 can also have a total of four lever elements 109. Two further lever elements can be arranged on the side of the torsion spring element 101 opposite the lever element 109 in the longitudinal direction 104. In this case, the third lever element connects the first torsion spring element 110 to the second torsion spring element 111. The fourth lever element 118 connects the third torsion spring element 112 to the fourth torsion spring element 113.

[0032] FIG. 2 shows a first embodiment of a shock absorber 200 of the present invention in two different perspective views. The shock absorber 200 of the first embodiment is similar to the shock absorber 100 of the prior art. Only the differences between the shock absorbers 100 and 200 are described below. Figure 1The same reference numerals are used throughout to indicate similar or identical elements.

[0033] and Figure 1 Compared with the shock absorber in Figure 2 The torsion spring elements 101 in the shock absorber 200 are connected to each other in different ways. The first lever element 117 connects the first torsion spring element 110 to the third torsion spring element 112. The second lever element 118 connects the second torsion spring element 111 to the fourth torsion spring element 113. Therefore, the torsion spring elements 101 are interconnected in a staggered manner, that is, the torsion spring elements 101 that are not directly adjacent are connected to each other, instead of being connected as shown in FIG. Figure 1 Like the shock absorber 100 in FIG.

[0034] The vibration dampers 100, 200 can be used, for example, to provide a spring mount, respectively. By means of a spring mount, for example, a motor or a machine can be mounted on a spring, which is particularly advantageous in the case of unbalanced motors and vibrators or corresponding vibration transmission systems with regard to the damping of oscillations and vibrations.

[0035] In order to connect the vibration dampers 100 and 200, these vibration dampers respectively have fastening protrusions. The fastening protrusions are respectively rigidly connected to the outer part 103 of the torsion spring element 101, so that the outer part 103 can be fastened to the base and the vibration block by the fastening element. A first fastening frame is arranged on the outer part 103 of the first torsion spring element 110. A second fastening frame is arranged on the outer part 103 of the fourth torsion spring element 114. The fastening frames are arranged on the outer sides of the outer parts 103 of the torsion spring elements 110 and 114 that are away from each other. Thus, the first torsion spring element 110 can be connected to the base. The second torsion spring element 111 can be connected to the vibration block. Instead of the fastening protrusions, a fastening frame can also be used, which is not rigidly connected to the outer part 103, but can be applied to the outer part 103 and connected to the base or the vibration block by fasteners.

[0036] In applications with high insulation requirements against vibrations and oscillations, it may be advantageous to reduce the natural frequency of the vibration absorber 100, 200 as much as possible. The natural frequency depends on the length 119 of the lever element 109. The longer the lever element 109, the lower the natural frequency of the vibration absorber.

[0037] However, the longer the lever element 109 is, the lower the load capacity of the shock absorber 100, 200 is. A reduction in the load capacity may require the use of additional shock absorbers 100, 200. The load capacity of the shock absorber 100, 200 also depends on the angle 121 enclosed by the lever element 109. The larger the angle 121 selected, the greater the load capacity of the shock absorber 100, 200.

[0038] By using a longer lever element 109, the height 120 of the vibration absorber 100, 200 measured perpendicularly to the longitudinal direction 104 or parallel to the first direction can be increased. As a result, the distance from the center of gravity of the machine, for example the vibration transmission system, to the base can also be increased. However, for reasons of stability and safety, this distance should be kept as small as possible, which applies in particular to the switching on and off processes of the vibration transmission system, because in these cases, the resonance curve of the vibration absorber 100, 200 is passed through.

[0039] Compared with the vibration absorber 100 according to the prior art, the vibration absorber 200 of the first embodiment allows the use of a longer lever element 109, so that the vibration absorber 200 of the present invention has a lower natural frequency. Figure 2 The torsion spring elements 101 are interconnected in a staggered manner, thereby reducing the distance of the center of gravity relative to the base. With this arrangement, the height 120 of the shock absorber 200 of the present invention is also reduced compared to the height of the existing shock absorber 100, so that increasing the angle 121 between the lever elements 109 can offset the excessive reduction in the load capacity of the shock absorber 200. Therefore, the length 119 of the lever elements 109, the height 120 of the shock absorber 200 and the angle 121 between the lever elements 109 can be balanced overall, so that the natural frequency, the load capacity and the distance of the center of gravity relative to the base can reach a desired or corresponding favorable value range.

[0040] Since the first lever element 117 and the second lever element 118 are arranged on opposite sides of the torsion spring element 101 along the longitudinal direction 104, the connection of the torsion spring element 101 in the shock absorber 200 of the first embodiment is achieved. Figure 1 An arrangement on one side of the torsion spring element is not possible because the lever elements 109 would interfere with each other.

[0041] Furthermore, according to the first embodiment, the vibration damper 200 is constructed in a symmetrical manner. More precisely, the torsion spring element 101 or its outer part 103 is arranged symmetrically with respect to a plane 122 extending perpendicularly to the first direction. The plane 122 extends parallel to the partition wall 116 between the second torsion spring element 111 and the third torsion spring element 112. This symmetry is related to the arrangement of the outer part 103. Thus, in the case of a load perpendicular to the longitudinal direction 104 or parallel to the first direction, the vibration damper 200 is compressed in the direction of the force and not in, for example, an oblique direction. As a result, the resulting load is evenly distributed to the torsion spring element 101, so that the vibration damper 200 can be used particularly effectively.

[0042] Figure 3 A second embodiment of the shock absorber 300 of the present invention is illustrated in two different perspective views. The shock absorber 300 of the second embodiment has similarities to the shock absorber 200 of the first embodiment.

[0043] Only the differences between the shock absorbers 200 and 300 are described below. Figure 3 In Figure 2 The same reference numerals in the drawings indicate similar or identical elements.

[0044] Unlike the vibration absorber 200 of the first embodiment, in the vibration absorber 300 of the second embodiment, the first lever element 117 and the second lever element 118 are configured in an angled manner. Therefore, the height 120 of the vibration absorber 300 of the second embodiment can be the same as the height 120 of the vibration absorber 200 of the first embodiment, for example, but the elastic element 107 can be more simply installed or connected to the inner part 102 and the outer part 103, respectively. Compared with the vibration absorber 200, the elastic element 107 in the vibration absorber 300 can be evaluated more intuitively.

[0045] Figure 4 A third embodiment of a vibration absorber 400 of the present invention is illustrated in two different perspective views. The vibration absorber 400 of the third embodiment is similar to the vibration absorber 300 of the second embodiment. Only the differences between the vibration absorbers 400 and 300 are described below. Figure 4 In Figure 3 The same reference numerals in the drawings indicate similar or identical elements.

[0046] Unlike the shock absorber 300 of the second embodiment, in the shock absorber 400 of the third embodiment, the first lever element 117 and the second lever element 118 are arranged on the same side of the torsion spring element 101 in the longitudinal direction 104. This is achieved in that the first lever element 117 is configured, for example, in an angled manner, the second lever element 118 is configured, for example, in a bent manner, and the first lever element 117 and the second lever element 118 are arranged to engage with each other. However, here, the first lever element 117 and the second lever element 118 are at least spaced apart from each other so that they do not abut each other when the shock absorber 400 is loaded.

[0047] The vibration damper 400 in the third embodiment makes it possible to more easily insert the elastic insert 107 into the inner part 102 on the side facing away from the lever elements 117 , 118 .

[0048] According to another embodiment, a further lever element can be arranged on the side of the shock absorber 400 opposite to the lever element 109. In this case, the shock absorber 400 has a total of four lever elements 109. The further lever elements are connected to the same torsion spring elements 101 as the lever element 109. Therefore, the further lever elements 109 are also connected to the torsion spring elements 101 in a staggered manner. Therefore, lever elements 109 are provided on both sides of each torsion spring element 101. As a result, the absorbed force is distributed to more lever elements 109.

[0049] All vibration dampers 200 , 300 , 400 described herein can each be designed as a one-piece cast steel component, wherein at least the inner part 102 , the connecting element 108 and the lever element 109 each form a one-piece cast steel component.

[0050] Figure 5 A side view of a vibration transmission system 500 is schematically shown. The vibration transmission system 500 can be configured as, for example, a linear vibrator or a circular vibrator. Figure 5 In Figure 2 The same reference numerals are used throughout to indicate similar or identical elements.

[0051] The vibration transmission system 500 has a vibration block 123 and, for example, a total of four vibration absorbers 200. Figure 5 Only two of the vibration absorbers are shown. More or less than four vibration absorbers 200 may also be provided. Merely by way of example, the vibration transmission system 500 has the vibration absorber 200 of the first embodiment. However, the vibration transmission system 500 may also have the vibration absorber 300, 400 of the second or third embodiment. The vibration absorber 200 is connected to the vibration block 123 and the base 124. For this purpose, the fastening protrusions or fastening brackets explained above may be used. The alignment of the vibration absorber 200 is only exemplarily described, wherein the common outer parts 114 of the respective second and third torsion spring elements 112, 113 of the vibration absorber 200 are arranged facing each other. However, they may also be arranged to deviate from each other or may be arranged to point in a common direction, for example. In the latter case, the first outer part 114 of the first vibration absorber 200 is arranged to face the second vibration absorber 200, while the second outer part 114 of the second vibration absorber 200 is arranged to face the first vibration absorber 200.
