Abstract
Description
[0001] Profile clamp with flange
[0002] The invention relates to a profile clamp with a flange according to the preamble of claim 1.
[0003] Profile clamps with V-profiles or other cross-sectional profiles are generally used to connect two lines or pipe sections that have radially projecting flanges at the ends to be connected. These flanges are often cylindrical or conical, and the profile clamp grips the flanges of the pipe sections with radially inwardly projecting legs. There is usually a gap between the inside of the profile or a base and the outside of the flange. The profile touches the flange at the radially inwardly projecting legs (V-profiles) to generate an axial load. When the profile clamp is tightened, the flanges are then pulled axially towards each other.
[0004] Such profile clamps are known, for example, from DE 198 82 234 B1 or EP 2 674 656 A1. The profile clamps have two half-shells, each extending circumferentially over half of the cylindrical or conical surface of the flanges. The half-shells have clamping heads at their first circumferential ends and corresponding first and second connecting structures at their second circumferential ends. The second circumferential ends of the two half-shells are connected to one another via the connecting structures, and the profile clamp then completely surrounds the flanges. Opposite the connection point of the second circumferential ends, for example, a clamping screw is guided through the two clamping heads to clamp and fix the profile clamp and then connects the two half-shells to one another at the other end.One disadvantage of existing profile clamps is that they are difficult to install due to the inherently limited opening angle of the clamp. Once the two circumferential ends are connected, the half-shells can only be opened to a limited opening angle, despite the use of articulated connectors between the circumferential ends. This complicates handling during installation of the profile clamp.
[0005] In addition, flange connections often cannot be equipped with such profile clamps due to limited space requirements or unsuitable secondary components. For example, in e-turbo applications or generally in electrical machines such as electric motors or generators, cylindrical housings are generally used. However, due to their design, the electrical components can be directly enclosed in box-shaped housings, for example, of power and voltage converters or directly connected gears. This eliminates the normally available installation space around the flange, and the profile clamp cannot therefore encompass the flange. Consequently, the profile clamp cannot be used in such special installation spaces.
[0006] The aim of the invention is to overcome these and other disadvantages of the prior art and to provide a profile clamp with improved compatibility, which can also be mounted quickly and easily on flange connections.
[0007] Main features of the invention are defined in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 15.
[0008] In a profile clamp with a flange, comprising a first partial shell which has a first clamping head at a first circumferential end and a first connecting structure at a second circumferential end, and a second partial shell which has a second clamping head at a first circumferential end and the first connecting structure at a second circumferential end, the invention provides that the flange, in the region of the second circumferential ends of the partial shells, has a second connecting structure complementary to the first connecting structures for releasably fixing the second circumferential ends of the partial shells. Due to the inventive possibility of directly fixing the second circumferential ends of the partial shells via the first connecting structures to the second connecting structures on the flange, the shells no longer need to be connected to one another at their circumferential ends.Advantageously, the opening angle of the profile clamp is no longer limited during assembly because the partial shells are fixed as separate shells to the flange via their second circumferential ends on the one hand and both clamping heads are facing each other and connected to each other via clamping devices in order to tighten the clamp.
[0009] Furthermore, the profile clamp can be used in hard-to-reach areas that do not allow for full clamping. The partial shells can preferably be designed in the circumferential direction such that the partial shells cover a cylindrical area and the second circumferential ends directly adjoin a differently shaped body (e.g., a box-shaped housing). Depending on the application, the partial shells and the second circumferential ends can preferably be positioned accordingly in the circumferential direction. This advantageously leads to a significant increase in the compatibility and handling of the profile clamp.
[0010] According to a preferred embodiment, the first connecting structures of the partial shells and the second connecting structures of the flange can engage with each other in a fixed state of the profile clamp in a form-fitting and force-fitting manner such that the circumferential loads and / or radial loads generated when the profile clamp is tightened can be converted into axial loads. The form-fitting and force-fitting connection between the two connecting structures creates a secure, releasable fixation between the partial shells of the profile clamp and the flange. The engagement geometry advantageously ensures the generation of axial loads in the flange connection. Other loads such as circumferential and / or radial loads that act on the partial shells and the two connecting structures during clamping and in the fixed state of the profile clamp are positively converted into axial loads.
[0011] According to a further preferred embodiment, the first and second connecting structures can form a latch, wherein the latch brings about a locking mechanism between the profile clamp and the flange during assembly. A latch and a locking mechanism associated with the latch have proven particularly advantageous because the profile clamp with the first connecting structures can initially latch into the second connecting structures during fixing and can be pre-positioned in order to then tighten the clamping heads, for example via a clamping bolt which can be passed through the two clamping heads. The pre-positioning can preferably be achieved by a simple hooking movement of the first connecting structures of the second circumferential ends of the partial shells into the second connecting structures of the flange. When hooked in, the connecting structures latch with one another.In addition, the locking mechanism is particularly cost-effective and easy to manufacture, whereby the locking mechanism can preferably be aligned on the flange and on the partial shells in such a way that, in addition to the advantageous locking effect, the desired clamping forces of the profile clamp can be safely transmitted in the fixed state.
[0012] Preferably, the partial shells of the profile clamp can extend in the circumferential direction of the flange such that the surface of the flange is partially enclosed by the partial shells when the profile clamp is fixed. Because the usually cylindrical or conical surfaces of flanges are only partially surrounded by the partial shells, rather than completely, the profile clamp can also be used in spaces with very limited installation space and strict packaging restrictions. For example, the profile clamp can be used on cylindrical flanges that directly adjoin a box-shaped or other-shaped housing of another component on one side and do not have a circular or cylindrical cross-section.Advantageously, due to the design of the partial shells and the flange, as well as the precise positioning of the first and second connecting structures, it is sufficient for one part of the flange or flange pair to be connected to be cylindrical or round. This advantageously increases the overall compatibility and usability of the profile clamp enormously. At the same time, installation is simplified because, inherently, there is no limited opening angle, as is the case with profile clamps connected to each other at the second circumferential ends, as is the case with prior art profile clamps. This ensures quick and easy installation, even in very tight spaces where a clamp with its full circumference cannot be attached and secured due to space restrictions.
[0013] According to a further preferred embodiment, the invention provides that the partial circumference of the flange enclosed by the partial shells corresponds at least to the circumference of a semicircle, preferably approximately to the circumference of a three-quarter circle. This positively ensures that the partial shells of the profile clamp encompass the flange at least sufficiently to be able to transfer the necessary loads and generate sufficient radial, circumferential, and axial tension. In particular, when the circumferential extent of both partial shells corresponds approximately to the circumferential length of a three-quarter circle, the advantages of increased usability and compatibility of the profile clamp, as well as the improved assembly and fixing properties, become apparent.
[0014] According to a further preferred embodiment, the second circumferential ends of the partial shells can be arranged diametrically opposite one another on the flange in the fixed state. The diametrical or circumferentially opposite arrangement of the second circumferential ends advantageously ensures easier positioning and handling of the profile clamp during installation on the flange. At the same time, this advantageously results in a uniform stress distribution during the fixing and in the fixed state of the profile clamp, and the clamping of the clamping heads via clamping devices as well as the engaging or hooking and pre-positioning of the second circumferential ends of the partial shells on the second connecting structures of the flange are further simplified.
[0015] Preferably, the cross-sectional profiles of the partial shells can be formed by base elements extending in the circumferential direction and two legs extending radially inward from the circumferential base elements. The base elements and the radially inward-facing legs of the partial shells can preferably be formed as a single piece and made of a single material. Further preferably, the clamping heads of the profile clamp can also be formed as a single piece and made of a single material with the partial shells, whereby the legs of the base elements can be produced by suitable forming processes.
[0016] This significantly reduces manufacturing and material costs. At the same time, the manufacturing process itself is simplified, and the desired cross-sectional profiles of the partial shells can be created much more quickly. The radially inclined legs project inwardly engage the flange surfaces and press the flange pairs axially against each other.
[0017] According to a further preferred embodiment, the partial shells of the profile clamp can be identically designed, whereby the partial shells can extend the same distance in the circumferential direction of the flange. This results in a symmetrical structure, which supports simple production on the one hand and an even load and stress distribution of the clamp in the fixed state on the other. Because the partial shells extend the same distance in the circumferential direction and only encompass a partial circumference of the flange in the fixed state, the clamping heads and the connecting structures are arranged exactly symmetrically, mirrored on a central, radial mirror axis of the flange.
[0018] According to a further preferred embodiment, the first partial shell of the profile clamp can be shorter or longer in the circumferential direction than the second partial shell of the profile clamp. Preferably, the second circumferential ends of the partial shells are nevertheless arranged diametrically to one another. Further preferably, the two clamping heads, which are connected and pressed together via a clamping element, can be shifted further towards the shorter partial shell by shortening one partial shell in the circumferential direction. Advantageously, the clamping heads, which by design project radially outwards, can thereby be shifted as desired along the circumferential direction, thereby further increasing the compatibility of the profile clamp. By shifting the two clamping heads, they can be arranged in a targeted, exposed position or in a free space, thus avoiding bulky packaging restrictions and tight installation spaces.This means that the profile clamp can also be used in more specific areas with very little installation space.
[0019] According to a further preferred embodiment, the first connecting structures of the second circumferential ends of the partial shells can be formed by recesses and axial webs, wherein the second connecting structures of the flange can be inserted and snapped into the recesses in such a way that the second connecting structures of the flange touch and engage around the axial webs at least in some areas. This creates a firm, secure fixation between the profile clamp and the flange. The second connecting structures of the flange can be easily inserted into the first connecting structures formed as recesses and snapped into place there.Because the axial webs are at least partially touched and enclosed by the second connecting structures during fastening, a radial pressure of the axial webs against the flange and the second connecting structures is advantageously created, which ensures that the profile clamp sits more firmly on the flange and can hook into place. At the same time, unwanted disengagement is also counteracted.
[0020] Preferably, the axial webs can directly adjoin the recesses, whereby the axial webs can be arranged at the end faces of the second circumferential ends. When the profile clamp is tightened or tensioned, the axial webs preferably press radially against the flange or the second connecting structures. As a result, the axial webs are advantageously displaced to the end faces of the second circumferential ends and form the outermost elements in the circumferential direction. This allows the recesses, axial webs, and second connecting structures to engage with one another more easily and securely.
[0021] According to a further preferred embodiment, the recesses can extend radially through the partial shells at the second circumferential ends, wherein the axial webs can be formed by the formation of the recesses at the second circumferential ends. This method has proven to be a particularly simple and cost-effective method for simultaneously creating the recesses and axial webs. In particular, production time is reduced because the axial web is already created after the recess is formed and does not need to be formed through additional production steps. At the same time, material costs for the formation of an additional axial web are saved.
[0022] Preferably, the recesses can be formed on the base elements of the partial shells, wherein the recesses can extend between the radially inwardly projecting legs across the entire axial width of the base element. The recesses preferably extend radially completely through the partial shells. Further preferably, the axial webs can be created by the remaining base element of the partial shell after the recess has been formed on the end faces of the second circumferential ends. This represents a simple and cost-effective method for creating the axial webs and recesses. Because the recesses are pronounced on the base element, the transmission of axial loads towards the flange connection is not disrupted. The legs therefore remain unchanged in their shape and can continue to completely and securely surround the flanges or the surface of the flanges, so that the flange pairs can be pressed axially against one another.
[0023] According to a further preferred embodiment, the second connecting structures of the flange can have a smaller axial extent than the recesses of the first connecting structures at the second circumferential ends of the partial shells. Due to the fact that the recesses are wider in the axial direction than the second connecting structures, which engage and can be inserted into the recesses, an engagement geometry is advantageously created between the first and second connecting structures which enables the generation of axial loads and ensures that circumferential and radial forces resulting from the tightening and fixing of the clamp can be converted into axial loads. The second connecting structures of the flange can preferably be formed by radially outwardly projecting locking elements, wherein the locking elements completely extend through the recesses of the second circumferential ends in the fixed state.This ensures a secure, firm connection between the profile clamp and the flange when fixing, and the second circumferential ends or the axial webs can be pressed radially against the locking elements and the flange during assembly.
[0024] Further preferably, the radially outwardly projecting locking elements can be hook-shaped. The hook shape advantageously further supports the locking or hooking of the first connecting structures of the second circumferential ends.
[0025] Preferably, the locking elements can be arranged at an angle with respect to a radial axis of the flange, wherein the locking elements are provided with guide bevels for guiding the axial webs of the first connecting structures. As a result, locking elements are advantageously designed as locking hooks on the flange element, which allow secure locking and fixing in the recesses of the first connecting structures of the partial shells. In addition, this enables the above-mentioned hooking movement during pre-positioning of the second circumferential ends on the flange and fixing of the profile clamp. The fact that the locking elements or the locking hooks are arranged at an angle on the flange with respect to a radial axis of the flange and extend completely through the recesses also counteracts unwanted disengagement during assembly.The guide bevels and the angled arrangement additionally support easy fixation and the aforementioned hanging movement or pre-positioning of the second circumferential ends of the partial shells, because the axial webs can advantageously be guided on the guide bevels of the locking elements when tightening the profile clamp and can be pressed against the flange body and the body of the locking element.
[0026] In order to enable the generation of axial loads, the hook-shaped locking hooks or locking elements are preferably designed to be narrower in the axial direction than the recesses of the second circumferential ends of the partial shells.
[0027] According to a further preferred embodiment, the locking elements can point away from the clamping heads of the profile clamp, wherein the locking elements can be arranged at an angle of at least 25° to 35° with respect to the radial axis. The locking elements can further preferably be arranged at an angle of approximately 30° with respect to the radial axis. In particular, an angle of approximately 30° between the radial axis and a continuation of the guide bevel has proven to be particularly effective and secure with regard to locking and hooking in. As a result, the locking elements point radially outwards and at the same time point away from the clamping heads that are in contact with one another, such that the axial webs securely engage around the hook-shaped locking elements and can be clamped in.
[0028] According to a further preferred embodiment, the locking elements of the flange can be formed as a single piece and made of the same material as the flange. This method has proven advantageous in terms of manufacturing and material costs. At the same time, the manufacturing effort is minimized.
[0029] Further preferably, the locking elements of the flange can be fastened to one another by means of a material fit, such as welding or gluing, or in another convenient manner.
[0030] According to an alternative preferred embodiment, the first connecting structures of the second circumferential ends of the partial shells can be formed by locking elements, whereas the second connecting structures of the flange can be formed by recesses complementary to the locking elements, into which the locking elements can be locked when the profile clamp is releasably fixed. This configuration provides an alternative implementation of the inventive idea to the previous configuration. Preferably, the locking elements of the first connecting structures can be hook-shaped and formed as a single piece and made of the same material as the base elements. The recesses on the flange can preferably be wider in the axial direction than the locking elements of the second circumferential ends of the partial shells, which are inserted into the recesses on the flange and fixed.
[0031] Further features, details, and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. They show:

[0034] Fig. 4a is a schematic representation of a connecting structure of the profile clamp according to the invention,
[0035] Fig. 4b is a schematic side view of a connecting structure of the profile clamp according to the invention,
[0036] Fig. 5 is a schematic representation of an alternative embodiment of the profile clamp according to the invention.
[0037] The profile clamp, generally designated 10 in Fig. 1, has a flange 30 which is surrounded on a partial circumference by the profile clamp 10.
[0038] The profile clamp 10 comprises a first partial shell 12, which has a first clamping head 2 at a first circumferential end and a first connecting structure 20 at a second circumferential end 22, and a second partial shell 14, which has a second clamping head 4 at a first circumferential end and also the first connecting structure 20 at a second circumferential end 22.
[0039] In the region of the second circumferential ends 22 of the partial shells 12, 14, the flange 30 has, at a corresponding circumferential position, a second connecting structure 21 complementary to the first connecting structures 20 for releasably fixing the second circumferential ends 22 of the partial shells 12, 14 to the flange 30.
[0040] When the profile clamp 10 is in the fixed state, the first connecting structures 20 of the partial shells 12, 14 and the second connecting structures 21 of the flange 30 engage with one another in a form-fitting and force-fitting manner such that the circumferential loads generated when the profile clamp 10 is tightened can be converted into axial loads. The first and second connecting structures 20, 21 form a locking connection, which, when the profile clamp 10 is mounted, creates a locking mechanism between the profile clamp 10 and the flange 30. As can be seen schematically, the partial shells 12, 14 of the profile clamp 10 extend in the circumferential direction of the flange 30 to such an extent that, when the profile clamp 10 is in the fixed state, the surface of the flange 30 is only partially and not fully enclosed by the two partial shells 12, 14.
[0041] As can be seen in particular from the partial shell 12 shown on the right, the first connecting structures 20 of the second circumferential ends 22 of the partial shells 12, 14 are formed by recesses 22' and axial webs 23 adjacent thereto, wherein the second connecting structures 21 of the flange 30 can be introduced into the recesses 22' and snapped into place in such a way that the second connecting structures 21 of the flange 30 touch and encompass the axial webs 23 at least in some areas.
[0042] By examining Fig. 2, it becomes clear that the partial circumference of the flange 30 enclosed by the partial shells 12, 14 approximately corresponds to the circumference of a three-quarter circle. The second circumferential ends 22 and the first connecting structures 20 of the partial shells 12, 14 are arranged diametrically opposite one another on the flange 30 in the fixed state.
[0043] As can be seen, the partial shells 12, 14 of the profile clamp are identically designed, with the partial shells 12, 14 extending the same distance in the circumferential direction of the flange 30. The two clamping heads 2, 4 rest against one another via two clamping lips 2", 4" and are pressed against one another when the clamp is tightened. Recesses 2', 4' are formed in the clamping heads, through which a corresponding clamping device, such as a clamping bolt (not shown), is passed. By tightening the clamping device and an additional spring element, the profile clamp 10 is tightened and fixed. The two clamping heads 2, 4 are arranged centrally and symmetrically between the identically designed partial shells 12, 14 and protrude radially outwards. The two identical partial shells 12, 14 and clamping heads 2, 4 are arranged symmetrically and mirrored on a central, radial mirror axis (not shown) of the flange 30.
[0044] As illustrated in Fig. 3, a symmetrical structure is not required. As can be seen, the second partial shell 14 is shorter in the circumferential direction than the first partial shell 12 of the profile clamp 10. Due to the shortening of the partial shell 14 in the circumferential direction, the two clamping heads 2, 4 pressed against one another are displaced further toward the shorter partial shell 14 and, as it were, protrude radially outward laterally on the circumference of the profile clamp 10.
[0045] As can be seen from the detailed representations of Fig. 4a and Fig. 4b, the recesses 22' project radially through the partial shells 12, 14 at the second circumferential ends 22, wherein the axial webs 23 are formed by the formation of the recesses 22' at the second circumferential ends 22.
[0046] The second connecting structures 21 of the flange 30 have a smaller axial extension in the axial direction A than the recesses 22' of the first connecting structures 20 at the second circumferential ends 22 of the partial shells 12, 14. The second connecting structures 21 of the flange 30 are formed by radially projecting, hook-shaped locking elements 32, wherein the locking elements 32 completely penetrate the recesses 22' of the second circumferential ends 22 in the fixed state.
[0047] The hook-shaped locking elements 32 are arranged at an angle with respect to a radial axis m of the flange 30, wherein the locking elements 32 are provided with guide bevels 35 for guiding the axial webs 23 of the first connecting structures 20. The locking elements 32 point away from the clamping heads 2, 4 of the profile clamp, wherein the locking elements 32 are arranged at an angle of approximately 30° with respect to the radial axis m.
[0048] Fig. 5 illustrates an alternative to the previously described embodiment. Accordingly, the first connecting structures 20 of the second circumferential ends 22 of the partial shells 12, 14 are formed by locking elements 26, while the second connecting structures 21 of the flange 30 are formed by corresponding, complementary recesses 36, into which the locking elements 26 engage when the profile clamp 10 is releasably secured.
[0049] The invention is not limited to the previously described embodiments, but can be modified in a variety of ways. In particular, the exact material combination, the circumferential dimensioning of the partial shells, or the precise structuring and design of the connecting structures can vary to ensure the required secure fixation of the clamp and the axial clamping of the flange connection. The profile clamp according to the invention can, for example, be designed as a V-profile clamp and used for connecting flanges in difficult-to-access installation spaces.
[0050] All features and advantages arising from the claims, the description and the drawings, including design details, spatial arrangements and method steps, can be essential to the invention both individually and in a wide variety of combinations.
