Mechanism of automatic infantry weapon

FIELD: infantry automatic weapon.

SUBSTANCE: the invention refers to automatic infantry weapon, to mechanisms which mobile links in extreme positions impact the weapon decreasing grouping of shots mainly to the mechanisms that lock the barrel's bore. In the weapon mechanism last driving member and connected with it intermediate links moving in the same direction are fulfilled light -weight, kinematically connected with a screw gear with two rotatable in the opposite direction fly-wheels which are accumulators of kinetic energy. Rotational axes of the fly-wheels are parallel to the axis of the barrel's bore and with one of these fly-wheels with a screw-gear a counter balance is connected moving in the opposite direction of the driving member and connected with it links. Reduced mass of the forward moving details of the group of driven link, availability of the counter balance of the driven link, construction and location of rotatable fly-wheels which have no forward moving, are offsetting the axes of impacts against the weapon from forward moving links and mutually offset reactive rotational moments acting against the weapon from the fly-wheels' side with additional stabilization of an angular location of the weapon from gyroscopic action of the fly-wheels reducing hitting and overturning of the mobile parts of the mechanism on the weapon.

EFFECT: increases grouping of automating shooting.

In known automatic small arms movable parts of the locking mechanisms, mechanisms for feeding the cartridge belt, mechanisms drummer and other produce in extreme operating positions strikes on weapons with energy equal to the total kinetic energy of linear motion in one direction of the links of the mechanism that reduces the accuracy of fire in the greater degree, the larger the mass and the speed of movement of the links relative to the weight of the weapon, which is a disadvantage of these mechanisms.

Known locking mechanism stem AEK-971 assault rifle designs of the Kovrov mechanical plant, taken as a prototype system exhaust gases and hard lock in which the locking mechanism includes divided by the mass of the breech with a rotating cylinder, which consists of two parts moving in opposite process, kinematically connected gear-rack and pinion, which in case of equality of the kinetic energy of these parts shutter provide equality and protivonapravlennyh power stroke of the parts of the shutter in the extreme positions. This compensates for the effect of the shock progressively moving parts of the shutter in arms, not compensating for the influence of the reactive torque from the rotation of the larvae, and is characterized by high dynamic balancing mechanism for irania. However, the mechanism of this design has no other more constructive means of increasing stability when shooting and not compensate the action of the shock torque from the rotary cylinder shutter, which is a disadvantage of the mechanism.

The aim of the invention is to eliminate this drawback of the prototype by introducing the mechanism of additional technical means of balancing, increases the stability when shooting.

In the first embodiment of the mechanism of this goal is achieved by the fact that the mechanism of small arms, containing the slave link and the associated intermediate and passive links translational and rotary action, moving with him consistently in one direction, these units, unlike the prototype, made lightweight, with the lowest possible mass for their mechanical strength, connection and installation dimensions, kinematically connected by a screw transmission with two opposite rotating flywheels, missing from the prototype, which batteries kinetic energy, dened in the bearings of the rotation locking in the axial direction, which prevents forward movement and the associated axial blows to the axis of rotation of which are mainly computers the flax stem.

In another embodiment of the mechanism, which is the improvement of the first, with the combination of all these structural elements of the first version of the mechanism, additionally contains a lightweight contrast, kinematically associated screw transmission with one of the wheels, moving opposite to the slave link with the movement of the kinetic energy is equal to the total energy of the group details of the slave link, and one of the flywheels, rotating opposite to the rotation of the rotary parts group slave link, for example, the rotation of the larvae of the shutter mechanism of the prototype, made with a moment of inertia equal to its kinetic energy, the total energy of the second flywheel and the rotary cylinder bolt.

In the first variant of the mechanism, the absence of axial blows to the arms from the side of the flywheel in the parish of parts of the mechanism in the extreme position, the mutual balancing reactive torque acting on the weapon side of the flywheel, the reduced mass of the linear motion links and additional gyroscopic stabilization, from the action of the rotating flywheels, simultaneously in vertical and horizontal plane, allows on this basis to obtain the stability of the weapon mechanism equivalent of a prototype or surpasses it,depending on the ratio of the mass of the flywheel and translationally moving parts.

The second variant of the mechanism is complicated additional counterweight translationally moving parts group slave link, with the increased weight of one of the wheels exceeds a prototype of the sum of the stabilizing factors affecting the stability of the weapon when firing.

The proposed design of the mechanism illustrated in the example mechanisms for locking the trunk with the semi-shutter and hard locking.

Figure 5 shows the locking mechanism of the trunk with the semi-shutter with flywheels associated bevel gear, in which one of the flywheel and counterweight shutter set at an angle of 90 degrees to about the and trunk.

Fig. 6, 7, 8, 9, 10 shows the options for the location of the flywheel bolt with a counterweight and shaft relative to each other in the locking mechanism of the trunk with the semi-shutter and rotating the trunk as one of the flywheels.

Figure 11 shows the locking mechanism of the barrel with the exhaust gases for vehicles with hard locking counter shutter placed in the zone of the gas chamber.

All drawings except 11, details of one destination designated by the same numerals. Return spring not shown on all drawings, since the execution and placement of the return spring is diverse and its placement not fundamentally affect the operation of the mechanism, and also because as a return spring in a number of designs mechanism can be used torsion springs associated with the flywheels.

In the drawings, for simplicity not shown elements of the guide surfaces of the bolt and the receiver.

The locking mechanism bore automatic firearms of figure 1, with the shortest layout moving parts, consists of linear motion along the guides of the receiver lightweight shutter 1 located on the sides of two bolt lugs 2, a bearing mounted in it and the firing pin and extractor, mainly determining the size of the shutter, two is protivopolojno rotating flywheels 3 and 4, located in the supports of rotation 5 of the receiver 6, is fixed in the axial direction on the end surfaces of the receiver.

The shutter 1 and the flywheels 3, 4 kinematically connected elements, helical gears, i.e. on the cylindrical surface of the flywheel is screw groove 7, with the side surfaces which interacts with the sliding of one of the fighting stops 2 shutter. The geometry of the helical grooves 7 of the flywheel the same step round and angle of the groove of the flywheel having equal moments of inertia, but have opposite direction of the helical line, which provides the opposite rotation of the flywheel at the same speed.

Over the grooves 7 it has variables calculated angles. In the initial part of the groove when the bolt is in the locking position, the angle of the helical grooves and the step orbits have small value to increase the braking force of the shutter during its acceleration at the beginning of the shot. On a plot of inertial motion of the bolt and flywheel after the termination of the return groove has a larger inclination angle and the step of revolution defined by the average rate rollback and roll forward of the bolt under the action of the return spring 8 and provides the specified rate of fire.

With such design, the grooves of the flywheel fighting stops shutter, shown in cross-section B-B, have the AGC bevels 9, interacting with the initial upper section of the groove, and a pair of bevels 10 that interacts with the side surfaces of the groove on its site inertial movement of parts of the locking mechanism. Fighting stops sliding in the guide slots 11, while holding the bolt from turning around its axis. Return spring 8 is seated on the guide rod 12, which is located above the axis of the shaft 13, is supported on the rear wall of the receiver and affects other end to the gate. Perhaps the design of hollow flywheels 3, 4 through cutting helical grooves 7 if necessary, install the return spring inside each wheel, as shown in figure 2.

In its rearmost position the bolt interacts with the buffer 14 possible bezbarernoy variant of the stop bolt in the rear position, when the bolt hits the bolt stops at the end of the spiral groove 7 of each of the flywheel. Geometric and gravimetric parameters of the flywheels 3, 4, and the angle of the helical grooves on the areas of accelerating and inertial motion of the bolt and flywheel, the characteristics of the return spring are defined: performance characteristics cartridge, nerazreshimosti case of the cartridge, the length of stroke of the shutter, the specified rate of fire. On the section a-a indicated angle αequal to 90...130 degrees, between the vertical plane and the overall plane, in which lie the axes of rotation of the flywheel permitted if necessary, rotate the flywheel about the axis of the shutter to ensure optimal conditions for the extraction sleeve.

The locking mechanism of figure 2 also has a light shutter 1 translationally moving along the guides of the receiver, with one combat focus 2, interacting simultaneously with the helical grooves 7 two different sizes of the flywheel 3 and 4 mounted in the bearings of rotation 5 of the receiver 6 with rigid fixation in the axial direction.

Flywheels mounted coaxially with the flywheel 3 inside of the flywheel 4, with possibility of rotation, and are hollow. The helical groove 7 is cut in the wall of the flywheel through.

The calculated geometrical dimensions of pitch and angle of the helical grooves 7 each wheel have different values as on the site of acceleration of the shutter and at the site of the inertial motion of the shutter, and have the opposite direction of the helical line to ensure multidirectional rotation of the flywheel. In accordance with the angle of the grooves is made of the angles of the bevels of the parts 9 and 10 of the combat emphasis, each interacting with its flywheel, the mutual arrangement of which is shown in section B-B.

Unlike the flywheel shown in figure 1, have the same dimensions, moments of inertia and the geometry of the screw is of Anavar, flywheels in this embodiment have different size diameters and different lengths of the shoulders of the application of the County force, which causes a certain relation in the calculation of the moments of inertia of the flywheel on the ratio of the radii of the application of a circumferential force of the flywheel. Internal flywheel 3 is outside the grooves 7 a cylindrical section with a spiral groove 15, which communicates the counterweight 16 shutter, made in the form of the coupling-nut, fixed against rotation, progressively moving along the cylindrical surface of the flywheel as it rotates opposite to the shutter, by performing the direction of the groove 15.

Drawing thin lines shows another possible arrangement of the counterweight 16 is in the area of the chamber to reduce the length of the weapon.

Counterbalance weight if necessary constructive reduce the length of its progress must be made larger than the total mass of the shutter 1 and the moving of parts, calculated from the condition of equality impact energy gate and counterweight in the extreme positions. If you need to solve the opposite problem - reduce the mass of the counterweight in comparison with the bolt, the length of its stroke must be proportionally increased. Return a cylindrical spring 8 in this embodiment is located inside the hollow wheels planted on the fixed rod 12 and is based omnimancer in zatylny part of the receiver, and the second end affects the eyelet combat focus 2 with a hole for the rod 12, responsible for the movement of the shutter. Other choices are possible installation and location recoil - nesosna the flywheels, for example, for the construction of weapons, in which the flywheels are close to the line of aiming, and aiming can be done through the inner hole of the hollow flywheel.

Shows the locking mechanism by smaller transverse dimensions and allows you to get a weapon with a tight layout with a fully balanced blows rotatable and translationally moving parts of the mechanism.

The locking mechanism on figure 3 is translationally moving the light shutter 1 with one martial focus 2, the counterweight 16 bolt with screw thorn within helical groove 15 of the flywheel 4, moving on the guide rod 12. Combat focus 2 interacts with the helical groove 7 of the flywheel 3. Different designs of the flywheels 3 and 4 are installed on poles of rotation 5 of the receiver 6 with fixation in the axial direction and are connected by a linked gear 17 with a gear ratio equal to or not equal to one. Geometrical parameters of the groove 7 provide the desired amount of braking force to the shutter, taking into account the inertia of the mass kinematically connected is it the flywheel 3, 4 and counterweight 16 under the action of the recoil forces of the shutter and when the inertial roll back to the rear position. Groove, as for any type of semi-shutter has two characteristic sites on the step of a coil with a small step on a plot of acceleration for the return and a big step on a plot of inertial motion of the bolt.

A spiral groove 15 links the operation of the shutter 1, and related links and counterweight 16, providing their opposite movement during operation, and the equality of the energy of their impact on arms in front and rear positions, which ensures the balance of effects on weapons translationally moving parts.

In case of equality of the sum of the masses of the shutter 1 and the associated parts of the counterbalance weight 16 and equal to one gear ratio gear 17, the helical grooves 7 and 15 have the same direction of cutting and the same step of a coil on a plot of inertial motion of the bolt and the counterweight. Otherwise the mass ratio of the gate and counterweight, step spiral grooves 7 and 15 is inversely proportional to the magnitude of the mass of interacting with them gate and counterweight.

To ensure equality of the torques acting on the part of the flywheel on the weapon, the flywheels 3 and 4 are made with equal moments of inertia at equal speed of rotation or with unequal moments of inertia, providing what their ratio, equal to the transmission ratio of the gearing 17. The flywheel 3 is made hollow, and inside it installed return spring 8 on the guide rod 12, one end resting on the wall of the receiver, and the other end acts on the counterweight 16. The buffer 14 is placed in the zone of movement of the counterweight 16. In this arrangement, the teeth 17 carries little more than half of the load from the efforts of the impact speed, and combat focus 2 is two times the load in comparison with the bolt stops of shutter mechanisms 1 and 2. The axial space "H" provides the shutter speed and placement of the trigger.

The scheme of the mechanism extends the choice of design of the seal in the ratio of the magnitude of its mass, since in all cases the effect on the weapon bolt with a larger mass is balanced by the weight of the counterweight 16 and the reduced mass of the flywheel.

Shows the locking mechanism, with the introduction of mutual coupling rotary flywheel gear with easy-to-variable ratio provides, as will be seen from subsequent drawings, a big opportunity rational layout of the weapons due to the locations and sizes of the flywheel 4.

The mechanism allows to achieve the coaxial arrangement of the flywheel 4 and the shaft 13, or to position the axis of rotation below the axis of the barrel, and also to reduce the length of the flywheel 4 and x is d counterweight 16 1.5...2 times.

In the mechanism in figure 4, the shutter 1 combat focus 2 is connected by a spiral groove with a flywheel 3, which gear 17 is coupled with the flywheel 4, mounted on the shaft 13. The flywheel 4 has a spiral groove 15, which interacts spiral spike counterweight 16, progressively moving along the guiding rod 12, opposite to the shutter through the execution direction of the helical grooves 15. Weapons with this locking mechanism has shortened zatylny part.

The locking mechanism of the trunk with the semi-shutter in figure 5, also has a light shutter 1 with combat focus 2, which is connected through a spiral groove 7 with the flywheel 4, which is characterized by the presence of conical gears 17, kinematically connecting the flywheel 3 to the flywheel 4, angled at 90 degrees, or other angles to the axis of the barrel in the vertical plane.

The flywheel 4 has a spiral groove 15, which interacts spiral spike counterweight 16, progressively moving along the guide rod in a vertical direction perpendicular to the axis of the trunk, or under other close to 90° angle defined by structural necessity. Running grooves 15 in the direction of the coils provides movement of the counterweight along the vector having the opposite direction component of the movement of the slide.

In this mechanism is the ZMA with a perpendicular orientation of the shock to the axis of the barrel vertically moving the counterweight 16, structurally enlarged shoulder against the force of the blows of the counterweight relative to the center of mass of the weapon, allowing more efficient use of the counterbalance weight to stabilize the angular position of the weapon.

Device locking mechanisms on Fig. 6, 7, 8, 9, 10 differs from the one considered the fact that one of the two flywheels are made constructively together with the barrel, with the possibility of rotation in the guide rotation of the receiver and fixed in the axial direction.

When using these mechanisms to prevent rupture of the cartridge case of the cartridge during rotation of the barrel relative to the shutter in the chamber are grooves, Revelli with a larger area, allowing the sleeve, coupled with the shutter to rotate in the chamber when the pressure of the powder gases.

Each of these mechanisms, including the slave link, which is a lightweight shutter 1 with combat focus 2, kinematically associated helical gear with the flywheel 3 or 4, linked gear 17, one of which is a barrel, and a counterweight 16, moving opposite to the shutter associated screw transmission with one of these wheels is the fulfillment of the shutter 1 and the counterweight 16 by mass, the geometry of the helical grooves 7, 15 wheels and interacting with them fighting stops 2 and thorn counterweight, zootoxin the e mass of the rotary shaft and the second flywheel is determined similarly to the method of calculation and geometric constructions listed items mechanisms of figure 1... 5, achieving the same effect balance bumps on arms translationally moving and rotating parts.

The locking mechanism on 6 differs in that the flywheel 3, the associated screw transmission gate 1, located in the zone of movement of the shutter above the axis of the shaft 13 and has a cylindrical section, which is the track surface for the counterweight 16 with a spiral groove 15, the control movement of the counterweight.

The return spring is made from a combination of a cylindrical compression spring, acting on the counterweight 16 and the torsion spring 8 mounted on the shaft, turning the barrel when in its original position. In zatylny part there is a buffer 14 bolt.

The mechanism has an easy short shutter and determines short zatylny part of the receiver.

The locking mechanism on 7 differs in that the shutter 1 is connected by a screw passing directly with the barrel 13 having a spiral groove 7 in the zone of the chamber, and coupled gear 17 with the flywheel 4, located below the axis of the barrel before the area of the chamber is connected by a screw transmission with a counterweight 16, mounted on the barrel as a guide.

Cylindrical return compression spring 8 is also mounted on the shaft and a working end rests on the counterweight 16 and the back plate of the receiver is set BU is EP 14 bolt.

Weapons with this mechanism is characterized by free and open top of the receiver.

The locking mechanism on Fig differs in that the shutter 1 with combat focus 2 is connected by a screw passing directly with the barrel 13 having a spiral groove 7 on the breech and coupled gear 17 with the flywheel 4, located below the axis of the barrel in the zone of the chamber. The flywheel 4 is kinematically connected by a screw transmission, including the groove 15 cut into the shank of the flywheel, counterweight 16 shutter mounted on the stem as a guide.

Return spring 8 is connected with the shutter, and the buffer 14 is installed in the front part of the receiver 6 and the work interacts with the counterweight 16.

Weapons with this locking mechanism has a short zatylny part of the receiver.

The locking mechanism in figure 9 differs in that the elongated shutter 1 has two combat focus 2, one of which communicates with a spiral groove 7 of the rotary shaft 13, act flywheel, and a second extreme position 2 with a spiral groove 7 of the flywheel 4, placed directly on the barrel as to guide rotation. On the rear of the flywheel 4 has a counterweight 16, spiral bound spine with a spiral groove 15 of the flywheel.

In the mechanism there is no gearing between the rotary shaft and the Mach is not far away.

Return a cylindrical spring 8 communicates with the shutter. On the front and zatylny side of the receiver 6 is placed buffers 14, interacting one with the bolt 1, the other with a counterweight 16 if necessary, split the buffer in order to reduce its size and power.

Weapons with this locking mechanism has a small transverse dimensions.

The locking mechanism according to figure 10, largely repeating the scheme of the mechanism of figure 2, characterized in that the shutter 1 has a combat focus 2, interacting simultaneously with a spiral groove 7 of the hollow flywheel 4, covering the breech of the barrel, and a screw groove 7 of the rotary shaft 13, also performs the function of guiding rotation of the flywheel, and therefore the mechanism is not gearing 17 between the swivel links.

Return a cylindrical spring 8 mounted on the shaft and communicates with the counterweight 16.

Instead of cylindrical compression springs 8 in this section of the trunk can accommodate a cylindrical torsion spring, one end of which is fixedly mounted in the receiver 6, and a movable end with the flywheel 4 or trunk. In zatylny part of the receiver placed buffer 14 that interacts with the shutter.

The design of the weapon with such a locking characteristic compact and suitable for the samples is of estolate gun.

Specialized weapons counterweight 16 may structurally be combined, for example, with Nadolny device.

The locking mechanism on 11 includes slave units - lightweight shutter housing 1 with a rotary cylinder 2 bolt engaged when turning hard clutch with the tabs of the receiver, moving progressively along the guides, kinetically associated screw transmission, including the groove 17 with the flywheel 4, which is coupled gear 5 with the flywheel 6. Flywheels 4, 6 mounted in bearings of rotation 7 of the receiver 3 with fixation in the axial direction. One of these flywheels, rotating oppositely to the rotation of the larvae of 2 paddles, made with a larger moment of inertia, ensuring equality of its kinetic energy to the total energy of the second flywheel and turning larvae 2.

Leading link piston 8 slides on the inner surface of the gas chamber 9, is rigidly fixed to the stem 10 having a hole 11 for venting propellant gases from the barrel.

Gas piston 8 has a spiral projection 12 moving along the guide slot 13 of the gas chamber that communicates with the sliding screw groove 14 made on the continuation of the flywheel 4 in the zone of movement of the protrusion 12, which is loaded by the force required for acceleration and movement of all moving parts of the fur the mechanism.

At the end of the cantilever part of the rotating flywheel 4 is screw groove 15, which interacts thorn translationally moving the counterweight 16 opposite to the movable parts 1, 2, 8.

Return a cylindrical compression spring 18 communicates with a gas piston 8 and returns links to the original position due to the unwinding of the flywheel 4 by the movement of the protrusion 12 is a spiral groove 14.

Based on all of the above-described locking mechanisms can be created mechanisms with the exception of the construction details of the counterweight 16 with elements of kinematic connection, simplifying the weapon, but with a slight decline in the balance of the steps of moving parts. Such mechanisms are of course alternative considered, constructive achievement of the smallest size and weight of the shutter and its parts.

In the drawings the location of the conventional buffer 14 corresponds to the traditional, for cases of shock interaction with him translationally moving the bolt in its rearmost position. The placement of such a buffer device requires some space and execution of the walls of the receiver, designed for axial impact load from moving parts.

When solving the problem of shortening the arms, it is advisable to renounce the use of Tr is conventional buffer, providing a stop valve by uticaria combat focus 2 in the closed end of the helical groove 7 of the flywheel, which excludes the impact of the shutter with the back plate of the receiver.

With such design, the flywheel their kinetic energy in the extreme rear position of the shock is transmitted to the receiver box through the support rotation in two opposite torques of equal magnitude, in addition to giving cross reactive forces and the axial component of the force arising and existing on the side of the helical groove 7 in the direction opposite to the movement of the shutter 1, determining the occurrence of compressive stresses in the longitudinal walls of the receiver cow, its size and weight.

On the other hand, to preserve the transverse strength of the receiver and the combat focus 2, perceiving the shock of the flywheel in its rearmost position, you must enter the damping elements in the design of the flywheel or the bearings of the rotation.

Mechanisms require careful execution of structural elements helical gears connecting the shutter and balanced with the flywheel in relation to zagryaznennosti, self-cleaning and dirt removal.

Introduction to mechanism design swivel wheels, which batteries kinetic energy, in addition to obtaining gyroscopic action, allows to reduce the weight of the moveable the piece at the expense of the flywheel, at a given operating amount of kinetic energy, increasing the estimated speed that does not require, as in the mechanism prototype, increasing the stroke length of the movable parts.

The number of revolutions of the flywheel in one move parts is determined by the optimum angle of inclination of the helical groove 7, 15, which must be not less than 3...4 values of angle-locking - angle of friction.

Step screw grooves 7, 15 is calculated on the basis of structurally defined stroke length of the bolt and cooperating parts.

In General, the effectiveness of the mechanism depends on the degree achieved facilitate linear motion of the links of the mechanism of the prototype, i.e. from reducing their size and weight.

The locking mechanism of figure 1 operates as follows.

The ignition of the charge sleeve begins to move the shutter 1 held through the fighting stops 2 helical grooves 7 of the flywheel 3 and 4. The axial component of the force of recoil of the bolt, the current through each battle, focusing on the side wall of the groove 7 of the flywheel, provides a component of force perpendicular to the axial force of bestowal, which is the flywheel torque force, the value of which depends on the angle of inclination of the grooves.

The force of the inertial braking of the shutter side of the flywheel is directly proportional to the calculated moment of inertia of the flywheel is in, providing the value of the angular acceleration of the flywheel, the speed and the amount of recoil that is safe against break liner cartridge in the period of acceleration from the pressure of the powder gases in the barrel. After overcoming the initial phase of the spiral grooves of the flywheel with a small angle and spin the flywheel up to the estimated angular velocity, battle 2 stops of shutter move on to the section of the grooves 7 having a large angle of inclination of the grooves, resulting in a light shutter begins to move faster through the extraction cartridge and cocked return spring 8 by the accumulated kinetic energy of the rotating flywheel communicating side walls of the grooves 7 through the fighting stops.

Rate rollback and roll forward on this part of the stroke of the shutter, depending on the speed of rotation of the flywheel and the force of the return spring determines the average cyclic shutter speed and rate of fire.

In its rearmost position the bolt hits the buffer 14 and stops together with flywheels, and then under the action of return spring 8 starts faster return to its original position, with the acceleration of rotating the flywheel in the opposite direction, producing the path of extraction and supply of the cartridge and the breech before the next shot.

When considering the impact of the movement of the moveable the piece under consideration of the locking mechanism to reject weapons, we must proceed from the fact that at the initial moment of recoil axial reaction on the part of the flywheel, acting on the receiver box, is part of efforts recoil and is not shown as a shock moving parts. After the disappearance of the efforts of bestowal, theoretically, jet action of the wheels on the weapon in the process, in the form of torque, acting in the transverse direction, are of equal magnitude, but opposite direction, i.e. balanced.

No translational motion of the flywheels do not have their own axial forces acting on the weapon and transmitted to the receiver box only efforts on them by the gate.

The shock of the translationally moving the shutter in arms in the extreme positions are not balanced, but their energy is reduced by reducing the mass of the shutter. This indicates an incomplete balanced axial forces acting in this weapon compared to the prototype.

The total efficiency of the balancing action of the moving parts of the locking mechanism depends on the ratio of the mass of translationally moving speed and total moment of inertia of the two flywheels.

The excess of the stabilizing gyroscopic action of two massive wheels on the moment of force created by the lightweight shutter determine the effectiveness of the mechanism in comparison with the prototype.

The locking mechanism of figure 2 operates as follows.

The ignition of the charge sleeve moves the stopper 1, which bevels 8 and 9 of the combat focus 2 acting on the side wall of the spiral grooves 7 of the flywheel 3 and 4 starts to rotate them in opposite directions with a speed that determines the rate of fire, while generating extraction of the sleeve, the compression of the return spring 8 and the movement of the counterweight 16 opposite the shutter due to the helical gears between the counterweight and the flywheel 3, consisting of helical grooves 15 of the flywheel 3 and screw the cleat of opposed, cooperating with the slide to side walls of the groove.

In its rearmost position battle focus 2 bolt hits the end of the helical grooves 7 of the flywheel 3 and 4 and stops along with the flywheel and counterweight. After stopping moving parts return spring 8 begins to move the shutter 1 and kinematically associated flywheels with a counterweight 16 in the opposite direction, making the extraction and supply of the cartridge and the breech.

When the mechanism of axial shock load on the weapon in the extreme positions from the side of the gate and counterweight by equality of their kinetic energy balance as well as the reactive torque of the flywheel by equality of their kinetic energy act is their weapons in the transverse direction.

This indicates that the full balance of the actions of the moving parts of the mechanism, as the mechanism prototype, and gives him an advantage over them due to the additional stabilization of the weapons from the action of the gyroscopic effect of the flywheel.

The locking mechanism on figure 3 translationally moving the shutter 1, shift from the action of the powder gases, combat focus 2 through screw transmission spins the flywheel 3 and the flywheel 4, associated gear 17, and moves the counterweight 16 associated helical gear with the rotating flywheel 4, and vvodit return spring 8 connected with the counterweight. During the course of the shutter extracts and extraction of the cartridge case. In the rear position, the counterweight 16 is faced with the buffer 14, and the combat focus 2 with stub end part of the helical grooves 7 moving parts to stop, and then the return spring 8 begins to move the counterweight 16, which circuit kinematic relations begins to reverse the movement of the flywheel and bolt 1, producing feed of the cartridge and the breech. This mechanism according to the degree of balance steps of moving parts identical with the mechanism of figure 2, and also has an additional stabilizing factor in the situation when shooting, what is the gyroscopic effect of the rotating wheels.

the address locking mechanisms on 4 ... figure 10, having a kinematic building, repeating basically the kinematic scheme of the mechanisms 1, 2, 3, is similarly described.

The design of the considered mechanisms are distinguished by the absence or presence of the gear 17, pin flywheels, and the spatial location of the links relative to the barrel and each other. In the arrangements according to Fig. 6, 7, 8, 9, 10 one of the flywheels is the barrel of the weapon.

Under the action of the powder gases through the bottom liner accelerating the shutter 1 through combat focus 2, interacting with the helical groove 7 of the two flywheels 3 and 4, or only with the groove 7 of one of the flywheel, when the mutual coupling of the flywheel gear 17, performs the rotation of the flywheel in the opposite direction, moving the existing counterweight 16, cocked return spring 8 and all operations of extraction and extraction sleeves.

After the arrival of the moving parts in the rearmost position, the return spring 8 through gate 1 or the counterweight 16 moves the parts of the mechanism in the reverse direction to its original position, during which the shutter 1 extracts the cartridge from the magazine, slams it into the chamber and locks the barrel of the gun. When providing constructive principle of the equality of the kinetic energy of oppositely moving shutter 1 and the counterweight 16 and the equality of the kinetic energy is AI opposite rotating flywheel 3 and the barrel 13 weapons, these mechanisms on the level of balance between work units and the degree of dynamic stabilization when shooting equivalent of mechanisms 2 and 3.

The mechanism 11, the characteristic mechanisms for rigid locking of the guns with the lower location of the gas chamber and the top location of the cartridge belt, works in the following sequence.

When fired, the gas piston 8 begins forward movement under pressure of the powder gases supplied to the gas chamber 9 of the shaft 10 through the opening 11, cocking his return spring 18. When this helical protrusion 12 of the piston 8 moves in a longitudinal slot 13, preventing rotation of the piston begins with acceleration to rotate the flywheel 4, interacting with its helical groove 14. Rotating the flywheel 4 through the transmission gear 5 rotates oppositely yourself flywheel 6, moves the shutter housing 1 and the larva 2 use is made on the flywheel groove 17, and the counterweight 16 which is connected by a stud with a spiral groove 15.

During this course part 1 and 2 paddles perform the unlocking of the barrel and extraction of the cartridge case.

After stopping the shutter housing 1 and the piston 8 in its rear position, the return spring 18 begins to move the piston 8 in the opposite direction, and all movable parts of the mechanism due to the kinematic connection between September the Ute reverse, producing removing the cartridge from the tape, ramming him into the chamber and the breech.

The mechanism in case of equality of the kinetic energy of the counterweight 16 and the total kinetic energy of the parts 1, 2, 8 and the equality of the kinetic energies of the turning of the flywheel 4 and 6, one of which includes a rotary energy larvae 2, exceeds the prototype for the dynamic balance of work units, improving his record accuracy of fire from the action of the gyroscopic effect of the rotating parts and trim rotary reaction larvae.

A real superiority in comparison with the prototype depends on the degree of ease - reduce the size and weight of the linear motion links and the relative increase of the weight of the swivel wheels.

The proposed design of the locking mechanisms and similar effects on a weapon other mechanisms solve the technical problem of improving the accuracy of automatic fire weapons.
