Description

[0001] A ROTOR IMPROVED FOR ROTARY BARREL FIREARMS

[0002] TECHNICAL FIELD

[0003] The present invention relates to improvements in rotors for firearms in general and more particularly for rotary barrel firearms such as miniguns.

[0004] BACKGROUND OF THE INVENTION

[0005] Conventional rotary barrel firearms, despite having the same calibers as single-barrel weapons, can inflict greater damage due to multiple barrels rotating at high speeds.

[0006] These systems perform loading, firing, and unloading functions simultaneously in different barrels, cooling the barrels during rotation and the entire rotor assembly can rotate. Rotary-barreled firearms contain multiple barrels mounted on a rotor, which are driven sequentially by a motor. In the firing position, one round is fired from the firing barrel at a time, and this cycle continues in a synchronized manner. Modern rotary-barrel firearm systems are multiple-barrel machine guns that fire rounds automatically and have a high rate of fire. They feature a rotary-barrel assembly driven by an electric motor powered by an external battery pack in aircraft, marine vessels, land vehicles, or similar environments. Modern rotary-barreled weapon systems have a rotor located in the center of the firearm. The rotor works in conjunction with other components during the firing sequence to complete the firing cycle. The rotor typically contains elevations located in the bolt assembly channels, which are connected by a locking mechanism called guides. The guides are usually mounted to the rotor by screws. The detachable and fixed guides on the rotor together form the sliding surface that allows the bolt assembly to slide forward and backward. The rotor's front face contains slots and channels that allow the barrels to be inserted and locked in place, usually by rotating the barrels one hundred and eighty degrees. When the firearm is fired, the motor turns the drive gear at the front of the rotor, which rotates the rotor counterclockwise and uses the cam track in the rotor shell to move the bolt assembly throughout the firing sequence. The shot is fired when the bolt assembly fires the ammunition.

[0007] The rotors of rotary barrel firearm systems, known in the state of the art, generally consist of a single piece made of steel alloy material, weighing approximately five kilograms. The rotor, which plays a crucial role in rotary barrel firearm systems, is a system component consisting of a single-piece body and the guides mounted on it. Driven by an electric motor, the rotor is a mechanical assembly that enables the bolt assembly to move through the bolt assembly channels and guides located on the rotor.

[0008] US Patent No. US11215424B1 describes firearms in general, and more specifically, rotary-barreled weapon systems and a rotor assembly for them. The rotary-barreled weapon systems described in US11215424B1 include a gear system driven by a motor, a rotor connected to the gear system, and a plurality of barrels mounted on the rotor.

[0009] The guides on rotors of rotary-barreled weapon systems, known in the state of the art, have a circular sliding surface. It has been observed that the circular sliding surfaces on rotors of rotary-barreled weapons, as known in the prior art, do not provide as good sliding performance in practice as they do in theory. Due to centrifugal forces, the circular surfaces cannot fully compress, causing wear and deformation of the sliding surfaces on the rotors and guides. Due to the circular structure of the rotor body, the bolt assembly's movement on the guides creates high friction. This high friction increases wear on the sliding surfaces, reducing rotor efficiency and shortening its lifespan. Furthermore, the circular structure of the sliding surfaces on the rotor also increases manufacturing and installation costs. Microroughnesses occur in rotors and parts interacting with rotors, especially during the machining of circular surfaces, which are included in the state of the art. These micro-roughnesses bring about other friction-related problems such as temperature increase, coating wear, reduction of material life, and corrosion during system operation. Creating the circular guideway surfaces on the rotor, which is part of the state of the art, requires specialized cutting tools. This results in high production (man-hour) and material costs. Furthermore, in rotors with rotary-barreled weapons systems, which are part of the state of the art, the guides are generally attached to the rotor at a single point. It has been observed that attaching the guides to the rotor at a single point causes the guides to rotate about the connection axis during operation. To prevent this problem, the present invention attaches the guides to the rotor at least at two points.

[0010] According to all these explanations, there is a need in the art for a rotating barrel gun rotor that can provide better sliding by reducing the friction coefficient and thus wear, while also reducing the weight of the rotor and providing cost advantages in production.

[0011] An invention related to the improvement made on the bolt assembly developed for rotary barrel firearms, developed by the inventors, was disclosed in the patent application no 2024 / 008483, which was filed on a previous date. The invention, which is the subject of patent application no 2024 / 008483, aims to solve the problems of circular guiding surfaces in bolt assemblies included in the state of the art, not providing good sliding and some of the semicircles not being pressed due to the centrifugal effect, thus causing wear and deformation on the guiding surfaces on the bolt assembly and the guides on the rotor, and to reduce the surface roughness values of the bolt assembly included in the state of the art and to increase the quality of the guiding surfaces. In addition, the invention of the patent application no 2024 / 008483, aims to reduce the manufacturing and assembly costs of the parts that affect movement in bolt assemblies. To overcome these problems, it has been proposed on the patent application no 2024 / 008483 that, instead of the semi- cylindrical circular guiding surfaces without any corner structure, guiding surfaces with corner structure and planar surfaces were proposed. Therefore, in order for the bolt assembly, which is the subject of the patent application no 2024 / 008483, to operate, a rotor structure developed in such a way that the sliding surfaces on the guides on which the bolt assembly moves are compatible with the bolt assembly channels (8) is required.

[0012] BRIEF DESCRIPTION OF THE INVENTION

[0013] The present invention relates to the improvements made for the rotor assembly (A) used in rotary barrel weapon systems in order to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field

[0014] It has been observed that the circular sliding surface (3a) of the fixed guides (4) and detachable guides (2) on the rotors (A) of the rotary barrel weapon systems, which are included in the state of the art, does not provide as good sliding as in theory in practice and that the semicircles do not exert full pressure due to the centrifugal effect, thus causing wear and deformation on the fixed and detachable guides (2, 4) on the rotor (Figure 2).

[0015] In order to reduce the problem of the circular sliding surfaces (3a) of the fixed guides (4) and detachable guides (2) located on the rotor (A) not being able to provide as good a sliding as in theory due to high friction during the advancement movement of the bolt assembly (1 ) on the rotor (A), included in the state of the art as shown in Figure 2, and the problem of some of the semicircles not being able to make full pressure due to the centrifugal effect, improvements have been made on the sliding surfaces (3) of the fixed guides (4) and detachable guides (2) of the rotor and on the rotor channels (5) as shown in Figure 3b. On the guiding structure which is the subject of the invention, the bolt assembly channels (8) are better fitted to the sliding surfaces of the guides (3) on the rotor, thus reducing the friction that occurs in the bolt assembly channels (8) and the sliding surfaces of the guides (3) during the movement of the bolt assembly, thus ensuring better sliding. In addition, in the rotor channels (5) and the fixed and detachable guides (2, 4) located on the rotor, which are included in the state of the art, the micro-roughnesses that occur on the surfaces during the machining of the circular sliding surfaces of the guides (3a) are more common than the machining of the planar sliding surfaces of the slides (3b). Therefore, with the invention, the surfaces of the rotor channels (5) and the sliding surfaces that enable the bolt assembly (1) of the fixed and detachable guides (2, 4) on the rotor to slide, contain planar sliding surfaces (3b) instead of the semi- cylindrical and circular sliding surfaces (3a) that do not contain an angular structure in the state of the art. Thus, the present invention has enabled the reduction of surface roughness values and the improvement of the quality of the sliding surfaces.

[0016] Moreover, with the present invention, it is possible to reduce man / hour times and thus production costs in the production and installation of the parts affecting the movement of the rotors (A) with circular sliding surfaces and the fixed and detachable guides (2, 4) on the rotor, which are included in the state of the art. The present invention has simplified the production of rotary-barreled firearm rotors and, by facilitating assembly, significantly reduced the problems of component deformation during assembly. The creation of circular sliding surfaces, which is already known, necessitates a specialized cutting tool. In the form of the invention, the sliding surfaces can be machined with standard cutting tools commonly and routinely used in industry.

[0017] With this development, the friction that occurs during the operation of the bolt assembly (1 ) on the fixed and detachable guides (2, 4) on the rotor is reduced and blockages are eliminated, thus reducing wear, preventing the decrease in sliding speed caused by friction, and increasing the life of the product and the efficiency of the process.

[0018] At the same time, with this development, a significant advantage has been achieved in carrying the weapon and increasing the maneuverability of the user by reducing the rotor weight by approximately 20% by machining the excess material in the nonfunctional parts corresponding to the channel corners in the rotor channels (5).

[0019] In the present invention, the sliding surfaces (3) on the fixed and detachable slides (2, 4) on the rotor are in a structure where the slides contain a sliding surface in planar form (3b), which includes at least two planar surfaces and joining areas where these surfaces come together at an angle to each other, as shown in Figure 12, instead of the sliding surface (3a) in circular form, which does not contain a cornered structure used in the prior art, as shown in Figure 11 . The junction area or areas where the surfaces meet at an angle to each other can be a “sharp-edged”, i.e. cornered structure, creating a cross-section in a linear line (Figure 13a), or a “non- sharp-edged”, i.e. curved structure, with no corners (Figure 13b). Preferably, the sliding surfaces (3) of the fixed and detachable guides (2, 4) of the present invention have a sharp-edged form with a polygonal angle, having at least two planar surfaces and at least one corner where these surfaces come together to form an angle with each other. Therefore, the sliding surfaces of the guides (3) which are the subject of the invention are formed by edges with a ridge where single corners in the shape of a “V”, two comers in the shape of a or “CZ” or planar surfaces come together to include more corners. The sliding surfaces of the slides which are the subject of the invention, more preferably, form ridges and edges comprising three planar surfaces and two joining regions where these three surfaces come together at an angle to each other and form an intersection in a linear line, that is, they comprise a ridge and edges in the shape

[0050] In this detailed description, the subject of the invention is explained only with examples that will not create any limiting effect on the better understanding of the subject.

[0051] As representatively shown in Figure 1 , the current rotary barrel firearm systems used in the state of the art generally have a plurality of barrels (20) mounted on a rotor (A) that is driven sequentially by a motor. The ammunition, which is connected to each other with ammunition cartridges in the form of a strip, is first installed on the weapon by opening the cover of the separation and feeding mechanism, and the ammunition separated from the ammunition cartridges by the separation mechanism is pushed into the ammunition channels (40) by the elements of the feeding mechanism and the bolt assembly (1 ). The ammunition is moved ahead along a cam track (60) with the bolt assembly (1 ) until it is loaded into the barrel (20) and fired. The bolt assembly (1 ) then move back, releasing the empty ammunition case for ejection. Moving ahead and back of the bolt assembly (1 ) are achieved by the interaction of a cam roller (roller) positioned on the upper surface of the bolt assembly (1 ) and the helical cam track (60) formed within the housing (50). As the rotor (A) rotates in a cycle, the cam roller follows the cam track (60) and adjusts the position of the bolt assembly (1 ) on the rotor (A) depending on where the bolt assembly (1 ) and rotor (A) are positioned within the cycle.

[0052] The invention relates to the improvement made on the rotor (A) which serves as a house for the bolt assembly (1 ), detachable guides (2) and barrels (20) mounted on, used in rotary barrel firearm systems, as shown in Figure 3b.

[0053] The rotor (A) which is subject to the invention is driven by a drive gear connected to the firearm's engine and often serves as a link to translate the rotary motion into a delinker gear. Thus, the firearm can be driven by the delinker itself. For proper operation of the weapon, it's crucial that the drive gear and delinker gear maintain correct timing relative to each other. It also provides the structure that keeps the barrel (20) and bolt assembly (1 ) aligned as the rotor rotates and allows for longitudinal displacement of the bolt assembly (1 ) as it moves with the rotor. This structure also features a locking mechanism that secures the bolt in the forward (firing) position, allowing each firing pin to release the firing pin. Over time, the locking mechanism wears to the point where it must be replaced for the weapon to function properly. Similarly, the gears wear. This wear can eventually necessitate the replacement of individual components, or even the entire rotor.

[0054] The rotor (A), one of the most basic elements of rotary barrel weapon systems, includes detachable guides (2) and fixed guides (4) mounted on the rotor channels (5) extending along the rotor body (A) and the rotor channel edges (7) located between these channels. These channels are the same number as the number of barrels (20) attached to the rotor (A). The bolt assembly (1 ), which moves along the rotor channels (5) on the rotor (A), achieves this movement by sliding on the sliding surfaces of guides (3) located on the edges of the fixed and detachable guides (2, 4) on the rotor, using the bolt assembly channels (8) on both sides. The bolt assembly (1 ), which moves along the rotor channels (5) on the fixed and detachable guides (2, 4), carries the loaded ammunition on the rotor (A), firing the ammunition, and removing the empty cartridge from the system after firing.

[0055] In a more detailed explanation, in rotary-barreled firearm systems, the rotor (A) functions as a bearing (body) for firing the ammunition and ejecting the spent cartridge case from the system by enabling the movement of the firing bolt assembly (1 ) on fixed and detachable guides (2, 4). This function is achieved through the sliding surfaces of the guides (3). The rotor channels (5) extending along the rotor body (A) allow the bolt assembly (1) to move on the rotor (A) via fixed and detachable guides (2, 4). This movement of the bolt assembly on the rotor is made possible by the compatibility of the bolt assembly channels (8) with the circular and sliding surfaces of the guides (3). More precisely, the bolt assembly channels (8) located longitudinally on the two side surfaces of the bolt assembly (1) and the sliding surfaces of the guides (3) fixed on the rotor (A) allow the bolt assembly (1 ) to slide back and forth on the rotor (A) to occur. Therefore, the fixed and detachable guides (2, 4) have surfaces that fit into the recesses of the sliding surfaces of the bolt assembly (6) formed by the bolt assembly channels (8) located on both sides of the needle assembly, while the rotor channels (5) serve as a slot (channel) within which the lower edge of the bolt assembly moves. The invention is essentially the implementation of the development made on the bolt assembly (1) developed for rotary barrel firearms, which is the subject of the patent application no TR2024 / 008483, on the rotor assembly on which this bolt assembly operates and especially on the rotor guides (2).

[0056] The detachable guides (2) of the rotor (A), which is included in the state of the art, consist of a metal part containing the circular sliding surface (3a) of the slides, whose two side surfaces have a semicircular curved form. The upper surface of these detachable guides (2) is flat. The lower surface has a longitudinal channel for the rotor channel edges (7) located between the rotor channels (5) to fit into. These detachable guides (2) are fixed to the rotor channel edges (7) through a hole located approximately in the middle. While the detachable guides (2) of the rotor are seated on the rotor channel edges (7) with longitudinal channels on the lower surface, the bolt assembly channels (8) on the side surfaces of the bolt assembly (1) are seated on the circular sliding surfaces of the guides (3a) that form the sliding surfaces (3) of the fixed and detachable guides (2, 4). Thus, the sliding surfaces (3) of the fixed and detachable guides (2, 4) form a rail structure on which the bolt assembly can move on the rotor guides via the bolt assembly channels (8). Since the movement of the bolt assembly (1 ) on the rotor depends entirely on the compatibility of the bolt assembly channels (8) formed by the bolt assembly sliding surfaces (6) and the sliding surfaces of the guides (3) on the rotor, these two must fully overlap.

[0057] In the patent application no TR2024 / 008483, for bolt assembly channels (8), planar sliding surfaces are proposed instead of the circular sliding surfaces of prier art. In the present invention, the sliding surfaces of the rotor guides (3) serve as rails, and in order to ensure perfect sliding and maximum efficiency, the edge forms and sliding surfaces of the rotor guides are designed as "planar sliding surface of the guides (3b)”, which includes a "planar" form, instead of the "circular sliding surface of the guides (3a)" which includes a "circular" form in the prior art. Similarly, the surfaces of the rotor channels (5), which are generally six in number in accordance with the number of barrels on the outer surface of the rotor (A), are also designed as planar surfaces, instead of the circular surfaces in the prior art.

[0058] Thus, in the present invention, the rotor (A) comprises planar sliding surfaces (3b) that form the edge forms of the fixed and detachable guides (2, 4) of the rotor. In the said embodiment, the sliding surfaces (3) of the detachable guides (2) and the fixed guides (4) mounted on the rotor channel edges (7) form a protrusion on the rail structure, and the said sliding surfaces (3) comprise at least two planar surfaces and at least one joining region where these surfaces come together at an angle to each other, forming an intersection in a linear line. In other words, the planar sliding surfaces (3b) on the rail structure formed by the sliding surfaces (3) of the detachable guides (2) and the fixed slides (4) comprise at least two planar surfaces and at least one joining region or regions where these surfaces come together at an angle to each other and join.

[0059] The present invention relates to a rotor (A) used in rotary barrel firearm systems, which includes rotor channels (5), rotor channel edges (7) extending along the rotor body (A), detachable and fixed guides (2, 4) mounted on the rotor channel edges (7). In the rotor (A) which is the subject of the invention, the sliding surfaces (3) of the detachable and fixed guides (2, 4) mounted on the rotor channel edges (7) form a protrusion in the rail structure and the sliding surfaces (3) in question comprise at least two planar surfaces and at least one joining region where these surfaces come together at an angle to each other, forming an intersection in a linear line, and the surfaces of the rotor channels (5) comprise at least two planar surfaces and at least one joining region where these surfaces come together at an angle to each other, forming an intersection in a linear line.

[0060] In the present invention, the rotor (A) comprises a planar surface formed by at least two planar surfaces on the surfaces of the rotor channels (5) and at least one junction area where these surfaces come together at an angle to each other, creating an intersection in a linear line.

[0061] In the present invention, the junction area or areas where the sliding surfaces of guides (3b) are in the planar form that form the edge forms of the fixed and detachable guides (2, 4) of the rotor and the surfaces of the rotor channels (5) meet at an angle to each other can be either "sharp-edged" (Figure 13a), i.e., angular, or "non-sharp-edged" (Figure 13b), i.e., curved, without corners. Within the scope of the present invention, the term "sharp-edged" refers to structures that include corners (Figure 13a); while the term "non-sharp-edged" refers to curved structures that do not include corners (Figure 13b).

[0062] In the rotor (A) embodiment which is the subject of the present invention, the planar sliding surface (3b) comprised of the bearing surfaces of the rotor channels (5) and the sliding surfaces (3) of the detachable guides (2) mounted on the rotor channel edges (7) and fixed guides (4) comprises at least two planar surfaces and at least one joining region where these surfaces come together at an angle to each other, forming an intersection in a linear line, and the said joining region has a sharp-edged structure.

[0063] Preferably, the planar sliding surfaces of the rotor guides (3b) and the surfaces of the rotor channels (5) of the present invention have a sharp-edged form with a polygonal angle, that is, an angular form, with at least two planar surfaces and at least one corner where these surfaces come together to form an angle with each other (figure 13a). Therefore, the surfaces of the fixed and detachable guides (2, 4) and rotor channels (5) form a single corner in the form of a “V”, which is two planar surfaces and one corner where these surfaces come together at an angle to each other; two comers in the form which are three planar surfaces and two comers where these surfaces come together at an angle to each other; or a polygonal form where planar surfaces come together to include more corners. More preferably, the planar sliding surfaces (3b) of the fixed and detachable guides (2, 4) of the rotor in question form a rail structure, particularly comprising three planar surfaces and two joining regions where these three surfaces come together at an angle to each other, forming an intersection in a linear line. Similarly, the surfaces of the rotor channels (5) form a channel comprising, in particular, three planar surfaces and two junction regions where these three surfaces meet at an angle to each other, forming a linear intersection. In other words, the planar sliding surfaces of the guides (3b) and the surfaces of the rotor channels (5) comprise rail and channel forms in the shape or "C", respectively. In the preferred embodiment of the invention, the planar sliding surfaces of the guides (3b) and the surfaces of the rotor channels (5), in particular, have a structure comprising two junction regions where the three surfaces meet at an angle to each other, forming a linear intersection in a way that creates a 90°, i.e., a right angle.

[0064] Thanks to the improvements described above made to the sliding surfaces of the fixed and detachable guides (2, 4) of the rotor (A) in question, the problem of the bolt assembly (1 ) not being able to slide as well as theoretically due to high friction during the advancement movement of the guides included in the state of the art on the sliding surfaces (3a) and the problem of some of the semicircles not being able to press due to the centrifugal effect has been reduced. Thanks to the guiding structure in question, by reducing friction, better pressing and sliding can be achieved with a smooth, full overlap between the bolt assembly channels (8) and the planar sliding surfaces (3b). Furthermore, since the planar sliding surfaces of the guides (3b) in question in the present invention contain planar surfaces, the surface roughness values can be reduced and the quality of the guiding surfaces can be improved. In addition, the present invention has reduced man-hour costs and production costs in the production and assembly of rotor skids with circular surfaces, which are included in the state of the art, and also reduced the problems of deformation of parts during installation.
