[0001] Gun barrel storage system and gun with the gun barrel storage system
[0002] The invention relates to a weapon barrel storage system having the features of the preamble of patent claim 1 and a gun having the weapon barrel storage system according to claim 20.
[0003] DE 10 2007 056 633 A1 discloses a barrel weapon with a barrel mounted in a weapon mount or cradle and a barrel support. An additional device in the form of a measuring and / or programming device is arranged in the area of the muzzle of the weapon barrel. An extension element extending to the muzzle of the weapon barrel is arranged at the front end of the barrel support, which supports the additional device located in front of the muzzle. The barrel support and the weapon cradle are individual elements that are firmly screwed together. The transmission of barrel vibrations leads to inaccurate aiming. The barrel support should be firmly connected to the weapon mount or cradle and be stiffened in such a way that it absorbs the barrel vibrations. The weapon barrel can be supported radially on the barrel support by means of a support element, which can also be referred to as a barrel bearing element.
[0004] DE 10 2011 106 199 B3 discloses a device and method for thermal compensation of a weapon barrel of a gun with at least one weapon barrel. The weapon barrel is mounted in a barrel cradle and, as an extension of the barrel cradle, in a barrel support. The barrel cradle serves for stabilization, guidance, and vibration damping and is continued into a barrel support that carries or supports the weapon barrel at several points. The gun comprises a lower carriage, a turret, and the barrel cradle with the barrel support in which the barrel is mounted. Temperature sensors are arranged on the barrel cradle and on the barrel support. The temperature is measured via the respective sensor, and the alignment of the weapon barrel in azimuth and elevation is corrected based on the temperature differences.
[0005] State-of-the-art weapon barrels are mounted so that they can move in the axial direction. At least one barrel bearing element is attached to the barrel to ensure that the barrel is securely mounted in the barrel support, even during recoil of the weapon. The barrel bearing elements are typically designed as hollow cylinders with a constant outer radius or outer diameter around the barrel. When a shot is fired, recoil forces occur which push the weapon barrel back in the axial direction. The axial travel of the weapon barrel is approximately 10 mm to 20 mm. The barrel bearing elements must therefore allow the weapon barrel to move in the axial direction. In addition, high temperatures are generated in a weapon barrel when the shot is fired. The geometry of the elements in the weapon can change relative to one another, not only due to the increase in temperature during firing, but also due to external influences such as sunlight. This can lead to the weapon barrel becoming jammed or to the barrel becoming loose.Its barrel bearing elements can become snagged on the barrel support, which alone can lead to inaccurate aiming. Furthermore, tilting leads to wear on the barrel bearing elements and / or the barrel support, which negatively impacts the guidance precision during the axial movement of the weapon barrel and thus leads to further inaccuracies. In extreme cases, it can even damage the weapon barrel and / or the barrel support.
[0006] Typically, in addition to the barrel cradle, only one barrel support is used, either in the center or at the muzzle of the weapon barrel. A barrel support with two additional barrel supports is relatively rare and originates from aircraft armament.
[0007] The invention is based on the object of improving the weapon barrel support system and the gun with the weapon barrel support system and, in particular, of designing and / or developing it in such a way that jamming / tilting of the barrel support element with the barrel support is avoided.
[0008] This problem underlying the invention is now initially solved by a weapon barrel storage system having the features of patent claim 1.
[0009] One aspect of the invention essentially lies in the fact that the barrel support element has at least two inner support regions for transmitting force between the weapon barrel and the barrel support element, wherein the barrel support element has at least one outer support region for transmitting force between the barrel support element and the barrel support, wherein the inner support regions and the at least one outer support region are formed alternately in the circumferential direction of the barrel support element. A further aspect of the invention is that the outer radius of the barrel support element is smaller in the inner support regions than in the outer support region. The thermal expansion from the weapon barrel is transferred to the barrel support element in the inner support regions of the barrel support element.Since the outer radius of the barrel support element is smaller in the inner support areas than in the outer support areas, the barrel support element can expand due to heat in the inner support areas without increasing its maximum outer diameter, which occurs in the outer support areas. This successfully prevents jamming between the barrel support element and the barrel support, since the force transmission between the weapon barrel and the barrel support element only occurs in the outer support areas. In particular, different materials with different thermal expansion coefficients can be used for the weapon barrel and the barrel support element, which are selected based on the respective different functions of the two components.
[0010] In one embodiment of the weapon barrel support system, a flattened portion is formed on the outer circumference of the barrel support element in each of the inner support areas. The flattened portion is formed essentially in a plane running parallel to the longitudinal axis of the weapon barrel.
[0011] Such a reduction of the outer radius of the pipe support element in the inner support areas is particularly easy to produce, e.g. by a milling process in which the milling cutter only has to be guided in one plane.
[0012] Adjacent to the outer support area of the barrel support element, a free space is advantageously formed between the weapon barrel and the barrel support element.
[0013] The clearance successfully prevents a force from being directly transferred between the weapon barrel and the barrel support element in the external support area.
[0014] In an advantageous embodiment of the weapon barrel storage system, the barrel support element has at least three, in particular four or five, internal support areas.
[0015] This optimizes heat distribution and thermal expansion between the weapon barrel and the barrel support element. Furthermore, the barrel support element provides particularly good radial support of the weapon barrel against the barrel support. In another embodiment of the weapon barrel support system, the inner support areas are evenly spaced circumferentially.
[0016] With three inner support areas and three outer support areas, an angle of 120° forms between two adjacent areas of the same type, which can be measured, for example, between the respective centers of the areas. With four inner support areas and four outer support areas, an angle of 90° forms accordingly.
[0017] Preferably, the barrel support element has substantially equal inner radii in the inner support areas in the axial direction of the weapon barrel.
[0018] This enables good force transmission between the weapon barrel and the inner support areas, since the weapon barrel usually has a constant outer diameter in the area of the barrel support element and thus contact can be created over the entire axial length of the barrel support element between the weapon barrel and the inner support areas.
[0019] In a further embodiment of the pipe support element,
[0020] Weapon barrel storage system in the external support area in the axial direction
[0021] Guide area with a maximum outer radius. The outer radius of the
[0022] The tube support element takes from a first end face facing a firing end of the weapon barrel and from a second end face of the tube support element facing away from a firing end of the weapon barrel in each case in the axial direction to
[0023] It steadily increases towards the guide area. The firing end of the weapon barrel is also called the muzzle.
[0024] This further reduces the risk of jamming / tilting between the pipe support element and the pipe support, as jamming is most likely to occur at the corners of the pipe support element on the end faces. If the diameter there is smaller than in the axially central area of the pipe support element, the pipe support element cannot jam / tilt there.
[0025] Advantageously, the outer radius of the pipe support element tapers conically from the first end face and / or the second end face of the pipe support element in the axial direction toward the guide area. Such conical contours are particularly easy to manufacture.
[0026] In a further embodiment of the weapon barrel support system, the outer radius of the barrel support element increases convexly from the first end face and / or from the second end face of the barrel support element in the axial direction towards the guide region.
[0027] This further reduces the risk of jamming / tilting between the pipe support element and the pipe support.
[0028] Preferably, the guide area is formed centrally on the pipe support element in the axial direction.
[0029] This further simplifies the manufacture of the barrel support element. Furthermore, when mounting the barrel support element on the weapon barrel, there's no need to pay attention to the alignment of the barrel support element to the weapon barrel.
[0030] Advantageously, the increase in the outer radius of the pipe support element is the same from the first end face and from the second end face of the pipe support element towards the guide area.
[0031] In this way, the production of the pipe support element is further simplified, since both sides adjacent to the guide area can be manufactured in the same way.
[0032] In an alternative, advantageous embodiment of the weapon barrel storage system, the guide region has a smaller distance to the first end face than to the second end face of the barrel storage element.
[0033] This optimizes the guidance of the weapon barrel during recoil. The longer side of the barrel support element is preferably aligned in the direction in which the weapon barrel is first accelerated during recoil.
[0034] The guide region preferably has a specific axial length, which is less than half, in particular less than one-third, of the axial length of the pipe support element. The pipe support element advantageously has a circumferential groove on the outer periphery in the guide region.
[0035] This groove has a beneficial effect on the air flows between the pipe support element and the pipe support during recoil, so that a kind of air cushion is formed between the pipe support element and the pipe support, thus reducing the friction between the pipe support element and the pipe support.
[0036] In an advantageous embodiment of the weapon barrel support system, at least one bore is formed in the barrel support element. The bore is radially aligned in one of the inner support areas of the barrel support element, with a bolt arranged in the bore and in a hole in the weapon barrel to connect the barrel support element to the weapon barrel.
[0037] In a further embodiment of the weapon barrel storage system, the bore opens into a groove bottom of the groove.
[0038] This minimizes the risk of a bolt causing jamming on the pipe support.
[0039] The weapon barrel support system preferably comprises a barrel cradle. The weapon barrel is rotatably mounted by means of the cradle, in particular on a gun. The barrel support is connected to the barrel cradle in a cantilevered manner toward the firing end of the weapon barrel. The weapon barrel can be supported radially on the barrel support by means of the barrel support element between a rotational axis of the barrel cradle and the firing end of the weapon barrel.
[0040] The support of the weapon barrel on the barrel support is preferably carried out by means of the barrel support element in a hollow cylindrical area of the barrel support.
[0041] Furthermore, the weapon barrel can preferably be supported in a rest position of the weapon barrel by means of a first barrel support element in the radial direction on the barrel support. Due to recoil when an ammunition is fired, the weapon barrel can be moved from the rest position in the axial direction into a recoil position, wherein during the movement of the weapon barrel into the recoil position, contact for radial support of the weapon barrel can be generated between the barrel support and a second barrel support element. This improves the radial support of the weapon barrel during recoil and thus target accuracy. This sliding of the second barrel support element into the barrel support is possible with a particularly low risk of jamming, particularly in the special design of the barrel support element with the guide area of maximum outer diameter.
[0042] The object underlying the invention is now further achieved by a gun with the weapon barrel storage system described above with the features of patent claim 20.
[0043] The gun barrel mounting system and the gun with the gun barrel mounting system are used primarily for land, vehicle, and sea-based air defense. The gun barrel mounting system and the gun with the gun barrel mounting system are used, for example, in medium-caliber guns, typically with an inner barrel diameter of 12.7 mm to 50 mm. Other areas of application for the gun barrel mounting system are revolver cannons, breech-loading cannons, or autocannons. Such breech-loading cannons are also referred to as gas-operated guns, which refers to an automatic firearm in which the reloading process is triggered by the gas pressure created by the combustion of a cartridge's propellant charge. An autocannon, on the other hand, has an external drive for the loading process instead of the energy of the high-pressure powder gases as in gas-operated guns. In the autocannon, the drive is achieved, for example, by means of a motor and a roller chain.
[0044] There are now numerous possibilities for advantageously designing and developing the weapon barrel storage system according to the invention and the gun with the weapon barrel storage system according to the invention. Reference is made to the claims subordinate to claim 1. A preferred embodiment of the weapon barrel storage system according to the invention and the gun with the weapon barrel storage system according to the invention will now be explained and described in more detail with reference to the drawing and the associated description. The drawing shows:

[0049] Fig.6 shows a schematic representation of a third embodiment of the weapon barrel storage system in a sectional view through the longitudinal axis of the weapon barrel.
[0050] Fig. 1 shows a schematic representation of a first embodiment of the weapon barrel storage system 1 and the gun 15 with the weapon barrel storage system 1 according to the invention in a side view. The weapon barrel storage system 1 comprises a weapon barrel 2, at least one barrel storage element, namely in particular a barrel storage element in the form of a first barrel storage element 3.1 and a
[0051] Pipe support element in the form of a second pipe support element 3.2 and a
[0052] Barrel support 4. In Fig. 1, two barrel support elements 3.1, 3.2 are shown. The use of just one barrel support element or more than two barrel support elements would also be conceivable. The barrel support element 3.1 or 3.2 surrounds the weapon barrel 2 at least partially. The weapon barrel 2 can be supported on the barrel support 4 in the radial direction r of the weapon barrel 2 by means of the barrel support element 3.1 or 3.2. In the axial direction a of the weapon barrel 2, movement between the barrel support element 3.1 or 3.2 and the barrel support 4 is possible.
[0053] When an ammunition is fired, the weapon barrel 2 moves in this axial direction a along a longitudinal axis L of the weapon barrel 2 due to the recoil. The barrel support element 3.1 or 3.2 has at least two inner support areas, namely in particular a first inner support area 5.1, a second inner support area 5.2 and a third inner support area 5.3, for transmitting force between the weapon barrel 2 and the barrel support element 3.1 or 3.2. The barrel support element 3.1 or 3.2 has at least one outer support area, namely in particular a first outer support area 6.1, a second outer support area 6.2 and a third outer support area 6.3, for transmitting force between the barrel support element 3.1 or 3.2 and the barrel support 4. The inner support areas 5.1, 5.2 and 5.3 and the at least one outer support area 6.1, 6.2 and 6.3 are arranged alternately in the circumferential direction u of the pipe support element 3.1 and 3, respectively.2. The outer radius R. a of the pipe support element 3.1 or 3.2 is smaller in the inner support areas 5.1, 5.2 or 5.3 than in the outer support area 6.1, 6.2 or 6.3. This is particularly evident in Fig.2 and Fig.3. The outer radius R a of the barrel support element 3.1 or 3.2 is measured from the longitudinal axis L of the weapon barrel 2 in the radial direction r of the weapon barrel 2 to the outermost point of the barrel support element 3.1 or 3.2. The outer radius R a , i in the respective inner support area 5.1 , 5.2 or 5.3 is in a plane, exemplarily in each plane perpendicular to the longitudinal axis L of the weapon barrel 2 smaller than the outer radius R a , A in the respective external support area 6.1 , 6.2 or 6.3.
[0054] On the outer circumference of the pipe support element 3.1 or 3.2, in the inner support areas
[0055] 5.1, 5.2, and 5.3, respectively, a flattened portion 7 is formed. For the sake of clarity, only the flattened portion 7 of the first inner support region 5.1 is provided with a reference symbol in Fig. 2 and Fig. 3. The flattened portion 7 is essentially formed in a plane parallel to the longitudinal axis L of the weapon barrel 2. It would also be conceivable to use other types of reductions of the outer radius R compared to the flattened portion 7. a of the pipe support element 3.1 or 3.2 in the internal support areas 5.1, 5.2 or 5.3.
[0056] Adjacent to the external support area 6.1, 6.2 or 6.3 of the pipe support element 3.1 or
[0057] 3.2, a free space 8 is formed between the weapon barrel 2 and the barrel support element 3.1 or 3.2. For clarity, only the free space 8 adjacent to the first outer support area 6.1 is provided with a reference symbol in Fig. 2.
[0058] According to Fig. 2 and Fig. 3, the pipe support element 3.1 or 3.2 has three internal support areas 5.1, 5.2, and 5.3, respectively. However, the use of two, four, or more internal support areas would also be conceivable. The internal support areas 5.1, 5.2, and 5.3 are evenly spaced circumferentially, as can be seen particularly from Fig. 2. Thus, according to Fig. 2, due to the number of three, they each form an angle of 120° to one another. When using only two internal support areas, the use of only one external support area would theoretically be conceivable.
[0059] The barrel support element 3.1 or 3.2 has essentially identical inner radii in the inner support areas 5.1, 5.2, and 5.3 in the axial direction a of the weapon barrel 2. This is particularly evident in Fig. 4.
[0060] The barrel support element 3.1 or 3.2 has essentially the same inner radii in the inner support regions 5.1, 5.2 or 5.3 in the axial direction a of the weapon barrel 2, as in the second exemplary embodiment of the weapon barrel support system 1 from Fig. 5 and the third exemplary embodiment of the weapon barrel support system 1 from Fig. 6. The second and third exemplary embodiments of the weapon barrel support system 1 from Fig. 5 and Fig. 6 differ from the first exemplary embodiment of the weapon barrel support system 1 only in the design of the outer contour of the barrel support element 3.1 or 3.2. The second and third embodiments of the weapon barrel storage system 1 also each have three inner support areas 5.1, 5.2 and 5.3 and three outer support areas 6.1, 6.2 and 6.3, wherein in the sectional views of Fig.5 and Fig.6 the third inner support area 5.3 and the first outer support area 6.1 are shown adjacent to the weapon barrel 2.
[0061] The pipe support element 3.1 or 3.2 has, according to Figures 1 to 6, in the outer support area 6.1, 6.2 or 6.3 in the axial direction a a guide area 9 maximum outer radius R a ,Amax. The outer radius Ran of the barrel support element 3.1 or 3.2 increases continuously from a first end face 10.1 facing a firing end E of the weapon barrel 2 and from a second end face 10.2 of the barrel support element 3.1 or 3.2 facing away from a firing end E of the weapon barrel 2, in each case in the axial direction a towards the guide region 9.
[0062] The outer radius R a ,A of the pipe support element 3.1 or 3.2 increases according to Figures 1 to 6 in the outer support area 6.1, 6.2 or 6.3 from the first end face 10.1 and / or from the second end face 10.2 of the pipe support element 3.1 or 3.2 in each case in the axial direction a towards the guide area 9 convexly.
[0063] The outer radius R a,A of the pipe support element 3.1 or 3.2 could, in contrast, also increase conically in the outer support area 6.1, 6.2 or 6.3 from the first end face 10.1 and / or from the second end face 10.2 of the pipe support element 3.1 or 3.2 in the axial direction a towards the guide area 9.
[0064] According to the second embodiment of the weapon barrel support system 1 from Fig.5, the guide region 9 is formed centrally in the axial direction a on the barrel support element 3.1 or 3.2.
[0065] According to Fig.5, the increase of the outer radius R a ,A of the pipe support element 3.1 or 3.2 from the first end face 10.1 and from the second end face 10.2 of the pipe support element 3.1 or 3.2 to the guide area 9 are equal. A first distance Li from the guide area 9 to the first end face 10.1 is equal to a second distance l_2 from the guide area 9 to the second end face 10.2.
[0066] Alternatively, according to Fig.1, Fig.2, Fig.3, Fig.4 and Fig.6, the guide area 9 has a smaller distance to the first end face 10.1 than to the second end face 10.2 of the pipe support element
[0067] 3.1 and 3.2, respectively. The smaller, first distance Li then has a smaller value than the larger, second distance L2.
[0068] The guide area 9 has a certain axial length which is less than half, in particular less than a third, of the axial length LR of the pipe support element 3.1 or
[0069] 3.2. The axial length of the guide area 9 is then given by the axial length L R of the pipe support element 3.1 or 3.2 minus the two distances Li and L2.
[0070] The pipe support element 3.1 or 3.2 has a circumferential groove 11 on the outer circumference in the guide area 9.
[0071] The groove 11 extends in particular through the inner support areas 5.1, 5.2, and 5.3, and in particular through the respective flattened portions 7. The groove 11 also extends in particular through the outer support area 6.1, 6.2, and 6.3.
[0072] At least one bore 12 is formed in the barrel support element 3.1 or 3.2. The bore 12 is aligned in the radial direction r in one of the inner support regions 5.1, 5.2, or 5.3 of the barrel support element 3.1 or 3.2, respectively. A bolt 13 is arranged in the bore 12 and in a hole in the weapon barrel 2 in order to connect the barrel support element 3.1 or 3.2 to the weapon barrel 2. It is conceivable that the bolt 13 is designed as a threaded bolt, so that the barrel support element 3.1 or 3.2 is screwed to the weapon barrel 2.
[0073] Preferably, a bore is formed in each of the inner support regions 5.1, 5.2, and 5.3, respectively, and a bolt is arranged in each bore and an associated hole in the weapon barrel 2, as shown in Fig. 2. For the sake of clarity, only the bore 12 and the bolt 13 in the first inner support region 5.1 are provided with a reference numeral in Fig. 2.
[0074] The bore 12 opens into a groove bottom of the groove 11 .
[0075] It is conceivable that the at least one bolt 13 is secured against loosening from the pipe support element 3.1 or 3.2 by a wire running circumferentially in the groove 11.
[0076] The weapon barrel support system 1 has a barrel cradle 14. The weapon barrel 2 is rotatably mounted by means of the barrel cradle 14, in particular on the gun 15. The barrel support 4 is connected to the barrel cradle 14 in a cantilevered manner toward the firing end E of the weapon barrel 2. The weapon barrel 2 can be supported on the barrel support 4 in the radial direction r by means of the barrel support element 3.1 or 3.2 between a rotation axis D of the barrel cradle 14 and the firing end E of the weapon barrel 2.
[0077] The support of the weapon barrel 2 on the barrel support 4 is preferably carried out by means of the barrel support element 3.1 or 3.2 in a hollow cylindrical area of the barrel support 4.
[0078] The weapon barrel 2 can be supported in a rest position 16 of the weapon barrel 2 by means of the first barrel support element 3.1 in the radial direction r on the barrel support 4. Due to recoil upon firing of an ammunition, the weapon barrel 2 can be moved from the rest position 16 in the axial direction a into a return position 17, wherein during the movement of the weapon barrel 2 into the return position 17, contact for radial support of the weapon barrel 2 can be created between the barrel support 4 and the second barrel support element 3.2. To symbolize this function, the second barrel support element 3.2 is shown in dashed lines in Fig. 1. List of reference symbols
