Description

Technical Field

[0001] This invention relates to the field of ammunition supply technology, and in particular to a chainless ammunition feeding interface device, a chainless ammunition feeding device, and an ammunition feeding method. Background Technology

[0002] Linkless ammunition feeding technology can improve the rate of fire, reliability, and energy consumption of aircraft cannon weapon systems. Compared with traditional chain-fed ammunition feeding, linkless ammunition feeding can significantly increase the rate of fire of automatic weapons, shorten the firing response time, and effectively reduce energy consumption during the ammunition feeding process. However, as the most complex component in automatic weapons, the ammunition feeding system accounts for 30%-70% of all failures. Especially in aircraft cannon applications, the space between the ammunition storage device and the ammunition feeding circuit is extremely limited due to the structural layout of the carrier aircraft, and traditional ammunition feeding interface devices are no longer sufficient to meet tactical requirements. For example, in the existing linear linkless ammunition feeding replenishment technology, each time ammunition is replenished, it first connects to the linkless ammunition feeding system, and then the ammunition is transferred to the closed ammunition belt of the linear linkless ammunition feeding system through the exchange of five ammunition feeding wheels. The number of ammunition exchanges is high, the replenishment device structure is too complex, and most of them are large-angle interfaces. However, due to the structural layout limitations of the carrier aircraft, the space between its ammunition storage device and the ammunition feeding circuit is small, and the traditional large-angle interface device is difficult to meet the platform requirements.

[0003] Therefore, there is an urgent need to design a technical solution that is simple in structure and can realize the handover of ammunition in a closed loop in a limited space. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The purpose of this invention is to provide a chainless ammunition feeding interface device, a chainless ammunition feeding device, and an ammunition feeding method to solve the problems existing in the prior art. The invention has a simple structure and can realize ammunition handover in a closed loop in a limited space.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Existing linear chainless ammunition replenishment technology involves connecting to a chainless ammunition supply system each time ammunition is replenished. The ammunition is then transferred to the closed ammunition belt of the linear chainless ammunition supply system through the interleaving of five feed wheels. This process involves numerous ammunition transfers, resulting in an overly complex replenishment device structure, often employing a large-angle interface. However, due to the limitations of the aircraft's structural layout, the space between the ammunition storage device and the supply circuit is limited, making it difficult to meet platform requirements with traditional large-angle interface devices. To address this technical problem, the first objective of this invention is to provide a chainless ammunition supply interface device, referencing... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a frame 1, a guide assembly, and a drive assembly 2. The frame 1 is used for the installation and connection between various structures and provides a movement channel for the closed cartridge belt. The guide assembly is located on the frame 1 and is used to guide and limit the ammunition 15 set on the closed cartridge belt. The drive assembly 2 is located on the frame 1 and can drive the closed cartridge belt so that the closed cartridge belt and the ammunition 15 move along the guide rail groove of the frame 1. The closed cartridge belt in this embodiment includes a cartridge holder 16. A link plate 17 is connected to the outside of the cartridge holder 16. Two adjacent cartridge holders 16 are movably connected through the link plate 17. A positioning bushing 18 is provided at the connecting end. The ammunition 15 is attached to the inside of the cartridge holder 16. The structure of the cartridge holder 16 is similar to a tile. The drive assembly is used to actuate the positioning bushing 18. The ammunition transfer device 19 of the present invention is located on one side of the frame 1, and the outlet of the ammunition transfer device 19 is located near the end of the guide rail groove. The ammunition 15 in the ammunition box enters the ammunition transfer device 19, and then enters the frame 1 through the guide rail groove and is transferred to the closed ammunition belt. This can realize the transfer of ammunition 15 between the ammunition box and the chainless ammunition feeding circuit under the condition of small wrap angle. The device has a compact structure and flexible layout, which improves the platform adaptability of the chainless ammunition feeding system.

[0035] In one embodiment, the frame 1 is a hollow cuboid structure, comprising a top plate 3 and a bottom plate 4 arranged in parallel. One end of the top plate 3 and the bottom plate 4 are fixedly connected by two parallel first side plates 5, and the other end is fixedly connected by two parallel second side plates 5. A guide rail groove is formed on the bottom plate 4, with a smoothly curved end that penetrates the side wall of the bottom plate 4. The end of the guide rail groove is located between the first and second side plates 5. The smooth structure of the guide rail groove can guide and limit the movement of the ammunition 15, facilitating the transfer of the ammunition 15. The side plates 5 support the bottom plate 4 and the top plate 3, and also fix the guide assembly. Through the limiting effect of the guide assembly, the trajectory of the closed ammunition belt is approximately a straight line.

[0036] In one embodiment, the guiding assembly includes a left limiting guide rail 8 and a right limiting guide rail 9. One end of the left limiting guide rail 8 is fixed to one of the first side plates 5, and the other end extends toward the second side plate 5 on the same side to a position near the end of the guide rail groove. One end of the right limiting guide rail 9 is fixed to another first side plate 5 on the side near the end of the guide rail groove, and the other end extends toward the second side plate 5 on the same side to a position near the end of the guide rail groove. The left limiting guide rail 8 has a smooth guide portion that deflects toward the side away from the first side plate 5, and the right limiting guide rail 9 has a smooth guide portion that deflects toward the side away from the end of the guide rail groove at the end away from the first side plate 5. The length of the smooth guide portion of the right limiting guide rail 9 is shorter than the length of the smooth guide portion of the left limiting guide rail 8, so that the ammunition 15 can be smoothly transferred between the left limiting guide rail 8 and the right limiting guide rail 9. The upper part and circumferential movement of the ammunition 15 are limited by the left limiting guide rail 8, the right limiting guide rail 9 and the sabot 16. The trajectory of the smooth guide part is adapted to the trajectory of the smooth curve at the end of the guide rail groove. During transmission, the bottom edge of the ammunition 15 is limited by the guide rail groove in the base plate 4.

[0037] To increase stability during transmission, in one embodiment, the guide assembly further includes a lower limit guide rail 6 and an upper limit guide rail 7. The lower limit guide rail 6 is fixed at both ends to a first side plate 5 and a second side plate 5 located on the same side, respectively. The upper limit guide rail 7 is also fixed at both ends to the first side plate 5 and the second side plate 5 located on the same side, respectively. The lower limit guide rail 6 has a smooth limiting portion that is recessed inwards towards the side away from the end of the guide groove near the end of the guide groove. The upper limit guide rail 7 has the same structure as the lower limit guide rail 6. The lower limit guide rail 6 and the upper limit guide rail 7 limit the movement of the spring support 16 and the chain link 17. The spring release wheel 13 acts on the positioning bushing 18 to drive the chain movement.

[0038] In one embodiment, the drive assembly includes two drive shafts 11, with both ends of the drive shafts 11 connected to the top plate 3 and the bottom plate 4. The two drive shafts 11 are located at both ends of the smooth limiting part, and the drive shafts 11 are located on the side of the smooth limiting part away from the end of the guide rail groove. Each drive shaft 11 is fixedly provided with two picking wheels 13, which can improve the stability during the picking process. The outer ring of the picking wheel 13 is provided with multiple picking teeth. Bearing assemblies 10 are installed on the top plate 3 and the bottom plate 4; the drive shaft 11 is installed on the bearing assembly 10 of the frame 1, and the lower part of the drive shaft 11 is provided with an end cover 12, which is connected to the adjacent bearing assembly 10 through the end cover 12 to realize the axial positioning of the drive shaft 11. The feed wheel 13 and the first gear 14 are fixed to the drive shaft 11 by splines. The top of the drive shaft 11 passes through the top plate 3 and is connected to the first gear 14. The bottom of one of the drive shafts 11 passes through the bottom plate 4 and is connected to the drive motor. Both first gears 14 mesh with the intermediate gear 21 to realize the transmission of power between the two drive shafts 11 and ensure that the two drive shafts 11 rotate synchronously.

[0039] A second objective of this invention is to provide a chainless ammunition feeding device, as described in the reference. Figure 5 As shown, the assembly includes a transfer device 19 and a chainless feeding interface device as described above. The transfer device 19 is located on one side of the frame 1, and its outlet is located near the end of the guide rail groove. The transfer device 19 is equipped with a driven shaft 20, which has a feed wheel 13 and an intermediate gear 21. This allows the drive shaft 11 to rotate synchronously with the driven shaft 20. The top of the driven shaft 20 passes through the transfer device 19 and is connected to a driven gear, which meshes with the main gear of the transfer device 19 for transmission. The chainless feeding interface device is bolted to the transfer device 19, and the drive shaft 11 of the transfer device 19 is matched in phase and transmits power through gears, thereby completing the transfer of ammunition 15.

[0040] The present invention also provides a method for feeding ammunition, comprising the following steps:

[0041] The drive motor controls the transmission shaft 11 to rotate, and the feed wheel 13 sequentially feeds the positioning sleeve 18 of the closed feed belt to drive the closed feed belt to move along the guide rail groove of the base plate 4.

[0042] When the drive shaft 11 rotates, the feed wheel 13 sequentially moves the positioning sleeve of the closed ammunition belt, the driven shaft 20 of the ammunition transfer device rotates, and the feed wheel 13 on the driven shaft 20 moves the ammunition in the ammunition transfer device to the end of the guide rail groove and enters the guide rail groove, while simultaneously engaging with the ammunition support 16 of the closed ammunition belt.

[0043] The feed wheel 13 continuously actuates the positioning sleeve 18 of the closed cartridge belt to drive the closed cartridge belt after the ammunition 15 is handed over to move along the guide groove of the base plate 4.

[0044] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
