Description

Technical Field

[0001] The present invention relates to a fastening device. The present invention further relates to a fiber machine, particularly a rotor spinning machine. The present invention relates to a digital twin. The present invention relates to a method for manufacturing a digital twin. The present invention relates to a computer program product. The present invention relates to a manufacturing method. The present invention relates to a computing device and / or a control device.

[0002] A fastening device, particularly a support, for receiving a bearing of a fiber machine, particularly a rotor spinning machine, is known in the prior art, for example, from German Patent Application Publication No. 10 2020 104 627 (A1). This publication discloses a bearing with a double-row rolling bearing for supporting a spinning rotor of a rotor spinning machine, in which case the outer ring is mounted in the bearing housing so as to be elastically displaceable.

[0003] Such fastening devices or supports may also be called elastic fasteners. These are functional elements or devices, in particular, for high-speed rotating components of textile machinery, especially rotor spinning machines, and the functional elements or devices can take over the positioning of supports for high-speed rotating components within textile machinery, especially rotor spinning machines, and can dampen vibrations caused by rotation. High-speed rotation is understood to mean components that rotate at rotational speeds exceeding 100,000 revolutions per minute, as achieved particularly in spinning rotors. To perform a function, elastic fasteners in the prior art consist of, in particular, at least one inner ring and at least one outer ring, in particular at least two outer rings, at least one damping element, and at least one run-on protection element. One or more damping elements are made of a vibration-damping material, in particular rubber, and are positioned, in particular, between at least one outer ring and at least one inner ring. This may include fixed connections, in particular adhesive and / or vulcanized connections. During use, the connection is particularly exposed to temperature and vibration, which can lead to loosening of the connection between the rings (inner and outer, especially the metal rings) and the rubber. If the connection fails, the support may disengage from its position, causing damage to other mechanical components. To limit the freedom of movement of the support in the event of connection failure, at least one run-on protection element is attached, in particular, to at least the starting and / or ending ends of the functional element. At least one run-on protection element is also used to limit the volume, particularly the rubber volume, that forms the gap between at least one inner ring and at least one outer ring. The design of the functional unit with a metal outer ring may also allow for corrosion processes to occur at the contact point between the elastic limiting part and the mechanical housing. The applicant implements effective protective and safety measures at the time of filing or on the priority date to prevent damage to the machine.

[0004] Therefore, an object of the present invention is to further improve the safety of the operation of textile machinery. In particular, an object of the present invention is to extend the operating life of textile machinery and thereby save resources. In particular, a further object of the present invention is to improve the operation of textile machinery.

[0005] This objective is achieved by a fastening device having the features of claim 1. This objective is further achieved by a textile machine having the features of claim 10. This objective is achieved by a digital twin having the features of claim 11. This objective is further achieved by a method for manufacturing a digital twin and / or fastening device having the features of claim 12. This objective is achieved by a computer program product having the features of claim 13. This objective is achieved by a method for manufacturing a fastening device having the features of claim 14. This objective is achieved by a computing device and / or control device having the features of claim 15.

[0006] Preferred embodiments of the present invention are the subject matter of the dependent claims and are described below.

[0007] According to one embodiment, the present objective is achieved by a fastening device having the features of claim 1 in particular.

[0008] A fastening device may be designed and configured to receive a bearing of a textile machine. In particular, the textile machine may be a rotor spinning machine. The fastening device may have at least one inner ring region and at least one outer ring region. The inner and outer ring regions may be formed integrally and further define the functional device. A region is understood to be a spatially defined region of a physical structure or component, and the respective body surfaces of the outward-facing structure or component, also called walls, define the region. Here, the outside of the physical structure is understood to mean the side of the body surface or wall that is located on the side facing away from the center of the physical structure, i.e., the side pointing away from the center of the physical structure, while the inside of the physical structure is understood to mean the side of the body surface or wall that is located on the side facing the center of the physical structure, i.e., the side pointing towards the center of the physical structure. Thus, the ring region is defined and limited in particular by the outside of the physical, in other words, three-dimensional ring walls. Thus, the inner ring region can be understood and viewed as the inner ring, and the outer ring region as the outer ring. The inner ring region, or both the inner ring and the outer ring region, or the outer ring, each comprises walls having surfaces that can define the outer, inner, and end sides in a corresponding manner. The characteristic of the ring region or ring is that it defines a passage through which physical structures such as walls and possible other physical structures of the ring or ring region are located.

[0009] The fastening device may be a support for bearings in a textile machine, particularly in the motor and / or rotor area, especially in a rotating part, especially in a high-speed rotating part. This improves the safety of the operation of the textile machine, extends the operating time of the textile machine, thereby saving resources, and improves the operation, especially the rotating, especially high-speed rotating part. A high-speed rotating part is understood to be a part that rotates at a rotational speed of more than 100,000 revolutions per minute in normal operation. Such a high-speed rotating part may be a spinning rotor of a rotor spinning machine, in particular in normal operation, i.e., spinning operation in which spun yarn is produced, and can reach higher speeds, for example, up to 180,000 revolutions per minute, and depending on the application, up to 250,000 revolutions per minute.

[0010] A fastening device is particularly distinguished in that the inner and outer ring regions, which form a functional device, consist of a single component, i.e., are formed integrally. In a preferred embodiment, the inner and outer ring regions are formed integrally. An integral design is understood to mean the design of different subcomponents, such as the inner and outer ring regions of a fastening device, from one or more of the same material, and the different subcomponents are connected to each other in any case so as to be joined integrally. The functions to be fulfilled by the fastening device (stability, damping of oscillation and / or vibration, bearing support) are made possible in particular by the geometric and material design.

[0011] In this case, the fastening device is designed to be axially symmetric with respect to its longitudinal axis, which can preferably form a rotation axis. The longitudinal axis is defined by the extension axis of the fastening device along its longest range. Thus, the transverse axis of the fastening device extends perpendicular to its longitudinal axis.

[0012] Furthermore, there may be regions of the fastening device where axial symmetry is interrupted, and locally, point symmetry with respect to the longitudinal axis may exist in a cross-section including the transverse axis. At least one inner ring region and at least one outer ring region are, in particular, regions in which the outer ring region at least partially surrounds the inner ring region. The outer contour of the outer ring region and / or the outer contour of the inner ring region may be at least partially interrupted in the circumferential direction around the longitudinal axis of the fastening device. Also, the outer ring region may have a cloverleaf structure, for example, in a cross-section perpendicular to the longitudinal axis. Two-leaf, three-leaf, four-leaf, ..., n-leaf clovers can function as basic shapes. A cloverleaf structure means, in particular, that the regions of the ring region extend toward the center and then extend outward again in other regions. The same may apply to the inner ring region accordingly. In other words, this means that the ring regions do not need to have a perfectly circular cross-section. Rather, they may be cross-sections, for example, based on spherical harmonics. The aforementioned cloverleaf structures may also be provided.

[0013] A bearing in textile machinery is specifically a bearing that allows the rotating part of the textile machinery to rotate. In particular, the rotating part is mounted so that it can rotate on a stationary textile machine, and thus forms a stationary reference frame. For this purpose, the bearing itself must also be able to support it. Fastening devices function particularly for this purpose and can therefore also be called supports for the bearings of the rotating parts of textile machinery, especially in the area of ​​rotors such as motors and / or spinning rotors.

[0014] In a preferred embodiment, the fastening device may include at least one bridge designed to integrally connect an inner ring region and an outer ring region to each other. In this way, the stability of the functional device can be enhanced, thereby enabling the fastening device to fulfill its intended functions (stability, damping of oscillation and / or vibration, bearing support) particularly through its geometric and material design. This improves the safety of the operation of the textile machine, extends its service life, saves resources, and improves its operation, especially its driving behavior.

[0015] A bridge is, in particular, a material connection between at least one inner ring region and at least one outer ring region, and the at least one inner ring region, at least one outer ring region, and at least one bridge can be formed integrally. The bridge may be designed and positioned to transition with its base into at least one inner ring region, and then, along a cross-section through the longitudinal axis, in a linear shape, particularly an S-shaped linear shape, away from at least one inner ring region and into at least one outer ring region. Alternatively or additionally, a step function may also be simulated by the bridge.

[0016] In a preferred embodiment, at least one bridge may be at least a first angle with respect to the inner ring region. Specifically, damping characteristics can be achieved by geometric design, in particular through at least a first angle, or a combination of at least two angles, and the length of the lever arm and / or different material thicknesses (i.e., widths). This improves the safety of the operation of the textile machine, extends the service life of the textile machine, thereby saving resources and improving operation, especially driving behavior.

[0017] Here, the first angle is formed particularly between the tangent extension in a linear bridge, particularly in an S-shaped linear bridge, and particularly between the base and / or lever arm of at least one outer ring region. In particular, the tangent can be positioned at the point having the greatest gradient to form the tangent extension. In particular, the cross section along the longitudinal axis of at least one outer ring region is formed as a lever arm. In this case, the lever arm can also be understood to mean that at least one outer ring region transitions through the bridge toward the base in the direction of the central cross section of the fastening device, and therefore toward at least one inner ring region. This is so that at least one outer edge region is designed to open outward toward the edge of the fastening device, particularly in a direction parallel to the longitudinal axis, and therefore can hang freely therefrom from a local viewpoint, and as a result, a lever arm can be formed, particularly at least locally, i.e., locally.

[0018] Alternatively or additionally, the bridge can form at least a second angle with respect to the transition area to the outer ring region. This can improve the safety of the operation of the textile machine, extend its service life, thereby saving resources and improving its operation, particularly its driving behavior.

[0019] The expression of the second angle can be understood, in particular, that the second angle differs from the first angle, especially with respect to its magnitude and / or sign. The second angle may be formed, in particular, between the tangential extension and the lever arm, both of which will be described elsewhere.

[0020] Alternatively or additionally, the bridge may comprise multiple bridge sections, of which at least two are at a second angle to each other. This can improve the safety of the operation of the textile machine, extend its service life, thereby saving resources and improving its operation, particularly its driving behavior.

[0021] The bridge section is understood to mean a region of the bridge that differs from other sections in terms of either the thickness and / or orientation of the material. In particular, this does not mean that the bridge is formed of multiple parts, but rather the bridge is formed integrally with at least one inner ring region and at least one outer ring region, as described particularly elsewhere.

[0022] In particular, the arrangement of the bridge sections can result in a spring structure, which can be distinguished by the alternating orientations in the cross-sectional plane along the longitudinal axis between upward-left and upward-right, and / or downward-left and downward-right. In other words, this means that when a cross-section passing through the cross-section along the longitudinal axis is "traced" from at least one inner ring region to at least one outer ring region, the bridge sections can each be angled with respect to one another, and the orientation of the bridge sections can accordingly alternate between leftward and rightward. This can also form a so-called accordion structure. In particular, at least two bridge sections can be angled with each other in a second angle, and in particular, other angles can also be provided.

[0023] Alternatively or additionally, the bridge may have recesses. On the one hand, this saves material, and especially weight. However, the corresponding holes and / or grooves can also serve, for example, for cooling, and / or can form channels for lubrication, allowing lubricant to be released into the fastening device, thus facilitating access to the bearing for periodic relubrication.

[0024] In this context, recesses should be understood to mean holes and / or grooves, as already mentioned above. Alternatively or additionally, especially in additive manufacturing, areas not filled with material can be provided, thereby forming corresponding recesses. These intentional defects can be used depending on the use of holes and / or grooves.

[0025] Alternatively or additionally, the thickness of at least one selected from the bridge, at least one transition portion, and at least one damping element section of the outer ring region may be tapered, particularly from the base where the bridge transitions into the inner ring region, particularly through the transition portion, toward the damping element section, particularly to the end of the damping element section. This may improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources, and improve operation, particularly driving behavior.

[0026] The damping element section can, in particular, represent the lever arm described elsewhere, which can be formed in particular by at least one outer ring region. The change in thickness corresponds in particular to the change in material thickness from the first wall to the second wall. In particular, whether or not recesses are provided in the wall can be ignored, as described elsewhere. Thus, thickness here refers in particular to a virtual path through the material from one side to the other, and recesses here are considered in particular to material inclusions.

[0027] In this case, a transition portion can be provided that transitions to at least one outer ring region. In particular, the transition portion may have a different orientation and / or thickness. This allows for optimization of oscillation and / or vibration damping.

[0028] In a preferred embodiment, the fastening device may have an intermediate space between the outer ring region and the inner ring region, which is designed in particular as a recess or in particular as a cavity. This can improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources and improving operation, especially driving behavior.

[0029] The term "intermediate space" should here be understood in particular as the area extending perpendicularly outwards from the central longitudinal axis and spreading by a line intersecting at least one inner ring area and at least one outer ring area, this area being defined by the inner wall of at least one outer ring area and the outer wall of at least one inner ring area. In particular, this is not filled by any material. Thereby, weight reduction can be achieved. Furthermore, the resulting shape enables the function of the functional device to be taken over accordingly, while on the one hand causing corrosion and on the other hand preventing material wear that can cause fatigue of the fastening device in the contact area between the parts of the multi-component fastening device.

[0030] In this case, the recesses or in particular the cavities can be understood as remaining empty during production and / or manufacturing of these areas, i.e., not being filled, for example, in an additional structure. In other preferred embodiments, the recesses and / or cavities may be at least partially hollowed out, thereby forming a free volume. In the context of additive manufacturing, corresponding support elements were necessary and / or important for the manufacturing, but post-processing can also be carried out to remove these support elements since they are no longer required to fulfill the function of the functional device described elsewhere.

[0031] According to a preferred embodiment, the intermediate space may be at least partially filled with a filling material. The filling material can be selected and / or designed to adapt the function of the functional device to specific application requirements.

[0032] In a preferred embodiment, the fastening device comprises, in particular in addition to at least one inner ring area and outer ring area and / or bridge, an extension of the functional device by additional elements. For example, by filling at least one intermediate space (also called free space) with another material, the damping characteristics in particular can be influenced.

[0033] Additional elements may include, for example, the inclusion of holes or grooves to facilitate access to the bearing for cooling or periodic re-lubrication. These grooves and / or holes may penetrate the outer wall of the fastening device in particular to reach the inner region where the bearing is positioned and housed. Further elements may include inserts that completely or partially enclose at least one intermediate space and can function, for example, to provide additional protection or to perform other functions such as fastening a support.

[0034] In a preferred embodiment, the fastening device may include at least one material selected from the group of materials consisting of metal alloys, plastics, natural materials, or material composites formed from the aforementioned materials, which integrally form at least one inner ring region and at least one outer ring region of the fastening device. In particular, all materials having both stability and damping properties are suitable. These include, among others, the aforementioned metal alloys, plastics, natural materials, or material composites formed from these materials. By selecting an appropriate material, in addition to positively influencing the damping behavior of the fastening device (also called an elastic fastener), it is possible to prevent the formation of corrosion between the functional device (also called a functional unit) and the machine holder. This can improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources and improving operation, especially driving behavior.

[0035] In a preferred embodiment, the fastening device may include at least one support column configured to separate at least one outer ring region from at least one inner ring region. This makes it possible to control damping as desired by at least one outer ring region held only by the support column or by a damping element in the shape of the support column. This can improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources and improving operation, particularly driving behavior.

[0036] A support or support shape can be understood here in particular as a shape in which the local outer wall of at least one inner ring region is connected to the local inner wall of at least one outer ring region. In particular, unlike the case of a linear, particularly S-shaped linear bridge, as described elsewhere, the base of the bridge does not transition to a lever arm, as described elsewhere. In the S-shape described above, in particular, it can be provided that the outer wall of at least one inner ring region transitions to the outer wall of the bridge, and this outer wall of the bridge transitions to the outer wall of at least one outer ring region. Since a support does not have an outer wall in the sense that it has a global wall, i.e., a wall visible across the entire surface of the support that faces away from the longitudinal axis of the fastening device, this connection does not exist, particularly in the case of a support. Rather, the support is positioned in particular in the intermediate space, as described elsewhere. In a preferred embodiment, the support extends particularly radially along at least selected imaginary lines that extend perpendicularly away from the longitudinal axis in order to define the intermediate space as described above.

[0037] In a preferred embodiment, the fastening device can be designed without run-on protection elements. By forming the functional device from a single component, failure of connection points within the functional device can be eliminated, thus reducing the need to use run-on protection elements in particular. This can improve the safety of the operation of the textile machine, extend its service life, thereby saving resources and improving its operation, especially its operating behavior.

[0038] As described in detail, run-on protection elements are used, particularly in multi-component fastening devices, to restrict the freedom of movement of the support, even in the event of a connection failure, especially between the damping element, which is made of rubber, and the inner and outer rings, which are made of metal. For this purpose, run-on protection elements are attached to multi-component fastening devices, particularly to the start and end ends of the fastening device. Run-on protection elements are also used to limit the volume of the damping element, especially the volume of rubber. If damping is achieved by the selection of shape and material, as described in detail, the damping element can be omitted, especially in the form of a rubber element. This also eliminates the possibility of connection failure, and thus the fastening device can be designed without run-on protection elements. In this context, particular attention must be paid to the necessity of these run-on protection elements. They may be placed for cosmetic reasons, but in particular, they no longer perform the technical function for which they were intended.

[0039] In a preferred embodiment, at least one reinforcing device can be introduced into the intermediate space. The reinforcing device may have legs in particular. This can improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources and improving its operation, especially its driving behavior.

[0040] The reinforcing device can, in particular, replace at least one run-on protection element that can no longer perform its original function, as described above. However, at least one reinforcing device can be provided, in particular at the starting and / or ending (i.e., edge) portions of the fastening device, thereby allowing for damping adjustment. Structural stabilization is also provided, which makes it possible to assign a support and / or brake to the lever arm that can dampen movement.

[0041] In a preferred embodiment, the reinforcing device can function as a restoring spring device, particularly via its legs, to act as a corresponding part of the lever arm as described elsewhere.

[0042] In an independent embodiment, a textile machine, in particular a rotor spinning machine, may have at least one fastening device as described in particular detail. The fastening device may be designed in particular as a support for receiving a bearing, in particular a bearing for supporting the spinning rotor of a rotor spinning machine. This can improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources, and improve operation, in particular operating behavior. The features, advantages, characteristics, and descriptions of fastening devices described elsewhere also apply to textile machines as appropriate. Thus, textile machines can be identified as appropriate by the features, advantages, characteristics, and descriptions described therein. Thus, fastening devices and textile machines can be identified by the features, advantages, characteristics, and descriptions relating to the methods and / or uses described elsewhere, as well as to computing devices, control devices, digital twins and / or computer program products.

[0043] In an independent embodiment, as will be described in detail, a digital twin of a fastening device may be provided. This may improve the safety of the operation of textile machinery, extend the service life of the textile machinery, thereby saving resources, and improve operation, particularly operating behavior. The features, advantages, characteristics, and descriptions of fastening devices described elsewhere also apply to the digital twin as appropriate. Thus, the digital twin may be identified as appropriate by the features, advantages, characteristics, and descriptions described therein. Thus, the digital twin may be identified by the methods and / or uses described elsewhere, as well as by the features, advantages, characteristics, and descriptions relating to fastening devices, textile machinery, computing devices, control devices, and / or computer program products.

[0044] In particular, a digital twin represents a machine-readable code that provides information in the form of electronic signals, which, when read or processed on a computing device and / or control device, enables at least partially to draw conclusions about the material, geometric and / or physical properties of an actual fastening device, as described elsewhere. Corresponding values ​​and parameters that can be experimentally determined can be stored, processed, read, and rewritten, and digital experiments and digital predictions based on the digital twin are also possible, such as the behavior of the digital twin in specific situations, such as specific installation conditions and / or specific rotational conditions and / or specific operating conditions such as speed. These predictions also enable conclusions and / or predictions about the behavior of the fastening device in the real world, for example, after manufacturing, by manufacturing methods as described elsewhere. In other words, a digital twin represents a digital electronic image of a real object.

[0045] In an independent embodiment, a method for generating a digital twin as described elsewhere may be provided. Alternatively or additionally, a method for manufacturing fasteners, in particular templates for fasteners, as described elsewhere may be provided. This may improve the safety of the operation of textile machinery, extend the service life of textile machinery, thereby saving resources, and improve operation, in particular, the operating behavior. The features, advantages, characteristics, and descriptions of fasteners, textile machinery, and / or digital twins as described elsewhere continue to apply to the method for generating a digital twin as appropriate. Thus, the method may be identified as appropriate by the features, advantages, characteristics, and descriptions described therein. Accordingly, fasteners, and textile machinery and / or digital twins may be identified by the features, advantages, characteristics, and descriptions relating to the method and / or use, and to computing devices, control devices, and / or computer program products as described elsewhere.

[0046] The method(s) may include at least one step of presenting a basic shape of a fastening device, in particular as a digital twin of such basic shape. The basic shape may have at least one outer ring region, at least one inner ring region, and in particular at least one bridge. The basic shape should be understood as a template, such as a first draft of a fastening device, in particular, enabling the provision of an initial shape for optimization.

[0047] This method may include at least one step of simulating, or providing, at least one physical parameter of a basic shape. The physical parameter may, in particular, be oscillation, damping, acceleration, and / or vibration. This makes it possible to perform the simulation based on at least one corresponding physical parameter, particularly related to at least one function of a functional device.

[0048] This method (one or more) may include at least one step of changing at least one design parameter of the basic shape, in particular thickness and / or at least one angle. Material constants may also be treated as corresponding physical parameters of the material used. The design parameter may, in particular, be the geometric progression of the shape, for example, a bridge. Alternatively or additionally, it may be the density of the filler and / or the distance between at least one inner ring region and at least one outer ring region. Alternatively or additionally, the design parameter may be at least one course of a line, in particular an S-curve, a bridge and / or an angle and / or material thickness, as described in particular elsewhere.

[0049] This method may include at least one step of simulating the physical parameters of the basic geometry after changing the design parameters. By simulating the physical parameters, it becomes possible to determine the effects of changes in the design parameters, particularly for performing optimization, as described below.

[0050] This method (one or more) may include at least one step of optimizing at least one design parameter by comparing at least one of the physical parameters after simulating or providing the physical parameters of the basic shape and / or the deformation of the basic shape.

[0051] In an independent embodiment, a computer program product may be designed to perform one of the methods described above when executed on a computing device. This can improve the safety of the operation of textile machinery, extend the service life of the textile machinery, thereby saving resources and improving its operation, particularly its driving behavior.

[0052] Alternatively or additionally, the computer program product may be designed and configured to output a digital twin, as described elsewhere, particularly when the computer program product is executed on a control device of a manufacturing apparatus.

[0053] As described elsewhere, the features, advantages, characteristics, and descriptions applicable to fasteners, textile machinery, digital twins, and methods for generating them or manufacturing fasteners by computing devices and / or control devices also apply as appropriate to computer program products. Therefore, computer program products can be appropriately identified by the features, advantages, characteristics, and descriptions provided herein. Thus, fasteners, textile machinery, digital twins, and methods for generating them and manufacturing fasteners, as well as computing devices and / or control devices, can be appropriately identified by the features, advantages, characteristics, and descriptions of computer program products.

[0054] In an independent embodiment, a method for manufacturing fastening devices as described elsewhere may be provided. This method may include at least one step of providing a template for the fastening device. The template may, in particular, be a digital twin, as described elsewhere. This may improve the safety of the operation of the textile machinery, extend its service life, thereby saving resources, and improve its operation, especially its driving behavior. Features, advantages, characteristics, and descriptions applicable to fastening devices, textile machinery, digital twins, computer program products, and methods for generating them, computing devices, and / or control devices, as described elsewhere, continue to apply accordingly to the method for manufacturing fastening devices. Thus, the method for manufacturing fastening devices can be identified accordingly by the features, advantages, characteristics, and descriptions described therein. Therefore, fastening devices, textile machinery, digital twins, and methods for generating them, computer program products, and computing devices, and / or control devices can be identified as appropriate by the features, advantages, characteristics, and descriptions of the method for manufacturing fastening devices.

[0055] The method may include at least one step of integrally forming at least one inner ring region and at least one outer ring region. In particular, it may provide additive manufacturing of at least a portion of a functional device. In particular, it may not be provided that the functional device can be formed from a block of material by removing material, but rather the body is formed by applying material layer by layer. In this case, a support structure may also be formed, which may be provided for the formation of the functional device and / or fastening device to stabilize the structure during assembly, but not for later use. This may also lead to post-processing steps in the field of additive manufacturing. The surface may also be reworked to meet the corresponding surface requirements of a support in a bearing of a textile machine.

[0056] In an independent embodiment, a computing device may be provided that includes a computer program product as described elsewhere. The computing device may be designed and configured to perform a method for generating a digital twin and / or fastening device as described elsewhere when the computer program product is executed on the computing device. This may improve the safety of the operation of the textile machine, extend the service life of the textile machine, thereby saving resources and improving its operation, particularly its operating behavior.

[0057] A computing device may be a CPU, computer, or corresponding apparatus designed and configured to execute computer program products, read and / or provide electronic signals, and enable corresponding methods for generating a digital twin. It may also enable simulations that allow the preparation and optimization of the digital twin, and to make available to the corresponding control device, in particular as electronic signals and / or alternatively on storage media such as USB, CD, DVD, Blu-ray, flash drive, SSD, and / or HDD, as described elsewhere.

[0058] Alternatively or additionally, a control device including a computer program product, as described elsewhere, may be provided. The control device may be designed and configured to perform a method for manufacturing fastening devices, as described elsewhere, when the computer program product is executed on the control device of the manufacturing apparatus. Alternatively, the control device may be connected to the manufacturing apparatus, even if it is located remotely.

[0059] The control device may be a corresponding device designed and configured to execute a computer program product, read electronic signals, and / or provide them, in order to enable a corresponding method for manufacturing fastening devices as described elsewhere, from a CPU, computer, or, in particular, a digital twin as a template.

[0060] The features, advantages, characteristics, and descriptions applicable to fasteners, textile machinery, digital twins, and methods for generating them or manufacturing fasteners, as well as computer program products, as described elsewhere, also apply appropriately to computing devices and / or control devices. Therefore, computing devices and / or control devices can be identified accordingly by the features, advantages, characteristics, and descriptions described therein. Thus, fasteners, textile machinery, digital twins, and methods for generating them and manufacturing fasteners, as well as computer program products, can be identified accordingly by the features, advantages, characteristics, and descriptions relating to computing devices and / or control devices.

[0062] The same reference numeral is used for elements and structures that have the same effect and / or are of the same type.

[0063] Figure 1A shows two cross-sectional views of an embodiment of the multi-component fastening device 5. In this case, the support 10 is formed for each bearing 55 (see Figure 5C schematically). Both embodiments shown in the cross-sectional views have features corresponding to the perspective view in Figure 1B. Figure 1B shows two external cross-sectional views of the embodiment of the multi-component fastening device 5 in Figure 1A.

[0064] In particular, the internal space 15 is formed therein by an inner ring 17, which is associated with a tube having a first diameter D1 and through which a longitudinal axis 39a can extend as an axis of symmetry 39. The outer ring 16 is made of metal accordingly and is associated with the inner ring 17 located on the outer surface 21 of the tube at the beginning and end of the tube. In this case, the outer ring 16 and the inner ring 17 are connected via a damper 20 which has a rubber material as a material filler 24 and connects the inner ring 17 and the outer ring 16 to each other.

[0065] The end 14 of the tube is open and, in particular, spaced apart by a length L. The outer diameter D2 is the outer diameter of the outer ring 16. In this case, the run-on protection element 25 is inserted into a housing 22 formed by the gap 18 between the outer ring 16 and the inner ring 17. In particular, the run-on protection element 25 is provided as the end portion of the gap 18 between the inner ring 17 and the outer ring 16. In the circumferential direction, the run-on protection element 25 is spaced apart from the outer ring 16 by a further gap 19. The run-on protection element 25 may have a recess 26 at its end that allows the run-on protection element 25 to be positioned in an oriented manner. As illustrated here, the recess 26 may be positioned at a distance of 120° in the circumferential direction around the longitudinal axis 39a.

[0066] The two embodiments shown in Figures 1A and 1B are compared with each other and differ only in the inlet 11, which is not included in the subject matter of the claims and can function for ventilation, cooling, and lubrication supply. Furthermore, a screw insert, which can assume a corresponding function and is located next to the inlet 11 in one embodiment, is also shown.

[0067] Figure 2A shows an external view of an integrated embodiment of the fastening device 5 according to a preferred exemplary embodiment. Figure 2B shows a perspective cross-sectional view of the integrated embodiment 5 of Figure 2A. The integrated embodiment of the fastening device 5 is designed and configured to receive a bearing 55 of a textile machine 100, in particular as schematically shown in Figure 5C. In particular, the textile machine 100 may be a rotor spinning machine. The fastening device 5 may have at least one inner ring region 36 and at least one outer ring region 34. The inner ring region 36 and the outer ring region 34 are particularly integrally formed. The fastening device 5 may be a support 10 for a bearing 55 of a rotating part of a textile machine 100, and in particular may be a support 10 in the region of a rotor such as a spinning rotor of a motor and / or a rotor spinning machine.

[0068] The fastening device 5 in the illustrated preferred embodiment is designed as a hollow cylinder and has an inner ring region 36 and an outer ring region 34 at each end. The two inner ring regions 36 form a tube surrounding an internal space 15 that functions in particular as a support 10 for a bearing 55. There may also be embodiments in which the inner ring regions 36 are at least partially separated from the rest of the tube by a material thickness portion 13, as shown as an example in Figure 3D. Each inner ring region 36 is integrally connected to the associated outer ring region 34 via a bridge 32, and the integral portion of the fastening device 5 from the inner ring region 36 through the bridge 32 to the outer ring region 34 forms an abstract S-shape. In particular, a base 41 is provided through which the bridge 32 transitions to the inner ring region 36. The base 41 is characterized in particular by projecting vertically from the outer wall 36a of the inner ring region 36 by a specified extension length, and the bridge 32 is formed integrally with the base 41. The outer ring region 34 and the inner ring region 36 are separated from each other by an intermediate space 38.

[0069] Figure 3A shows a schematic partial longitudinal section of an integrated embodiment of the fastening device 5, where at least one bridge 32 forms at least a first angle a with respect to the inner ring region 36 (left side of the figure). A base 41 may also be provided, through which the bridge 32 transitions to the inner ring region 36. An exemplary stepped shape corresponding to a Z shape is shown here.

[0070] Alternatively or additionally, the bridge 32 can form at least a second angle b with the transition region 31 of the outer ring region 34. The transition region 31 and the outer ring region 34 can also be positioned relative to each other at a third angle (not shown) (right side of the figure). Here again, the embodiment is designed particularly as a single unit. The second angle b extends particularly between the tangential extension of the bridge 32 and the transition region 31, particularly its tangential extension.

[0071] The fastening device 5 can be designed symmetrically or asymmetrically, and therefore, as shown in Figure 3A, it may have different functional devices at both ends, consisting of an inner ring region 36 and an outer ring region 34. The functional devices shown herein can occur individually or in any conceivable combination with the embodiments described in Figures 3A to 3E.

[0072] Figure 3B shows a schematic partial longitudinal section view of an integrated embodiment of the fastening device 5 according to a further preferred exemplary embodiment. On the left side of the figure, an embodiment of the functional device is shown, in which the fastening device 5 has an intermediate space 38 between the outer ring region 34 and the inner ring region 36, and this intermediate space 38 is designed in particular as a recess or in particular as a cavity. In the illustrated embodiment, the bridge 32 has in particular several bridge sections 32a, 32b, 32c. These may be at different angles to each other, but in particular at least two may be at a second angle b to each other. Herein, an example of an accordion structure that can function as a spring element is shown.

[0073] On the right side of the figure is an embodiment in which the thickness d of at least one damping element section 35 of the bridge 32, the transition portion 37, and the outer ring region 34 tapers, starting from the base 41 where the bridge 32 transitions particularly into the inner ring region 36, and particularly through the transition portion 37, towards the damping element section 35, and particularly to the end of the damping element section 35.

[0074] The fastening device 5 can be designed symmetrically or asymmetrically, and therefore may have different functional devices at both ends, as shown as an example in Figure 3B. The functional devices shown herein can occur individually or in any conceivable combination with the embodiments described in Figures 3A to 3E.

[0075] Figure 3C shows a schematic partial longitudinal section view of an integrated embodiment of the fastening device 5 according to a further preferred exemplary embodiment. Here, on the left side of the figure, an embodiment of a functional device is shown, in which the fastening device 5 has an intermediate space 38 between an outer ring region 34 and an inner ring region 36, which is designed in particular as a recess or in particular as a cavity. This intermediate space 38 may be at least partially filled with a filler 44, as shown as an example on the left side of Figure 3C. On the left side of the figure, an embodiment is shown in particular in which the bridge 32 has several bridge sections 32a, 32b, 32c. These may be at different angles to each other, in particular at least two of which may be at a second angle b to each other (see Figure 3B). Here, an example of an accordion structure which can function as a spring element for damping oscillation and vibration is shown. The accordion structure is filled with a filler material 44. An accordion structure consisting of multiple bridge sections 32a, 32b, and 32c can be provided, or any of the other described embodiments for the bridge 32 can be provided and combined with the filler 44 in the intermediate space 38.

[0076] On the right side of the figure, a functional device is shown in particular in which the base 41 has recesses f. These recesses f serve, on the one hand, particularly to cool the bearings and / or to supply lubricant to the bearings. According to an exemplary embodiment (not shown), one or more recesses f having defined dimensions may also be provided in the bridge 32, the inner ring region 36, and / or the outer ring region 34.

[0077] The fastening device 5 can be designed symmetrically or asymmetrically, and therefore may have different functional devices at both ends, as shown as an example in Figure 3C. The functional devices shown herein can be generated individually or in any conceivable combination with the embodiments described in Figures 3A to 3E.

[0078] Figure 3D shows a schematic partial longitudinal section view of an integrated embodiment of the fastening device 5 according to a further preferred exemplary embodiment. In particular, at least one reinforcing device 50 is introduced into the intermediate space 38 and has legs 45, 47 or legs 49, 51 in particular. The legs 45, 47, 49, 51 serve to reinforce the structure in particular, but can also be designed as damping elements. In particular, they can take over the function of the filler 44 and therefore can replace it in particular.

[0079] Furthermore, as described above, the inner ring region 36 is formed as a connecting region for the transition portion 37 having the material thickness portion 13. The transition portion 37 merges with the bridge 32, to which the outer ring region 34 is connected. The inner ring region 36 is formed integrally with the outer ring region 34 via the material thickness portion 13, the transition portion 37, and the bridge 32.

[0080] According to a preferred embodiment (not shown), the support column 42 can be positioned in the intermediate space 38, as shown in the cross-sectional view of the fastening device 5 in Figure 3E, to locally connect the inner ring region 36 to the outer ring region 34 and partially support the outer ring region 34. In this way, the target damping effect can be achieved.

[0081] Furthermore, if the intermediate space 38 is not filled with the filler 44, separation of the connection can no longer occur, and therefore the run-on protection element 25 is not necessary; thus, the fastening device 5 can be designed without the run-on protection element 25 in particular.

[0082] The fastening device 5 can be designed symmetrically or asymmetrically, and therefore may have different functional devices at both ends, as shown as an example in Figure 3D. The functional devices shown herein can be generated individually or in any conceivable combination with the embodiments described in Figures 3A to 3E.

[0083] Figure 3E shows a schematic cross-sectional view of an integrated embodiment of the fastening device 5 according to a further preferred exemplary embodiment. The fastening device 5 has, in particular, a support column 42 to connect and support an inner ring region 36 and an outer ring region 34 to each other and to separate them. Here, the support columns 42 are, for example, arranged at a 45-degree angle to each other in the circumferential direction around a longitudinal axis 39a that is perpendicular to the transverse axis 39b and extends through the intersection of the transverse axis 39b.

[0084] In the preferred embodiment of the fastening device 5 shown in and described herein, the at least one inner ring region 36 and the at least one outer ring region 34 of the fastening device 5 are made of a material selected from the group of materials consisting of metal alloys, plastics, natural materials, or material composites formed from the aforementioned materials, in order to integrally form the at least one inner ring region 36 and the at least one outer ring region 34 of the fastening device 5. In the embodiment shown herein, the bridge 32, the transition portion 37, the base 41, and the support 42 are also integrally formed with the at least one inner ring region 36 and the at least one outer ring region 34, and are therefore formed from the same material in particular.

[0085] Figure 4A shows a schematic diagram of method 200 for generating a digital twin 110. Alternatively or additionally, as described elsewhere, method 200 for manufacturing a fastening device 5, in particular a template for the fastening device 5, can be provided.

In this case, presentation specifically refers to providing corresponding electronic information and / or data that can be made available in the digital twin 110. The basic shape may have at least one outer ring region 34, at least one inner ring region 36, and at least one bridge 32 connecting the inner ring region 36 to the outer ring region 34.

[0089] In step (IV), where at least one physical parameter of the basic geometry is simulated after (III) the design parameters have been changed, the effect of the change in design parameters on system performance and / or physical behavior can be simulated. This makes it possible to check the changes immediately, in particular, in order to perform step V, which is optimization.

[0090] In step V, which optimizes at least one design parameter, in particular to optimize system performance, at least one of the physical parameters can be compared to the physical parameters from an iteratively previous step after simulating or providing the physical parameters of the base shape and / or deformation of the base shape.

[0095] Figure 5B shows a schematic diagram of a manufacturing apparatus 145 having a control device 140. The control device 140 has, in particular, a computer program product 120 as described elsewhere. The computer program product 120 may, in particular, have instructions for controlling the manufacturing apparatus 145, or may include machine-readable code that can determine such instructions. The control device 140 may be designed and configured to execute method 300 for manufacturing a fastening device 5, as described elsewhere, when the computer program product 120 is executed on the control device 140 of the manufacturing apparatus 145. The manufacturing apparatus 145 receives electronic signals to control the apparatus of the manufacturing apparatus 145, in particular, for example to control the removal of material (top-down method) and / or to allow the additional deposition of material (bottom-up method).
