Description

Стрелковое оружие с подвижным стволом Moving barrel small arms
Изобретение относится к оружейной технике, а именно, к установке ствола огнестрельного оружия в ствольной коробке.The invention relates to weapons technology, namely, to install a barrel of a firearm in a receiver.
Известно автоматическое огнестрельное оружие по патенту RU, 2241940, кл. F41A 3/54, 2004г., в котором ствол установлен в направляющих короба с возможностью наката и отката. Свободному движению ствола препятствует трение в контактных поверхностях ствола и ствольной коробки. Трение усиливается по мере износа поверхностей и особенно при попадании в зазор мелких твердых частиц, например, песка. Известно огнестрельное оружие по патенту RU, 2258883, кл. F41A 21/36, 2005г., в котором ствол установлен в ствольной коробке, содержащей амортизирующее устройство в виде пакета подвижных в осевом направлении колец, имеющих возможность взаимного перемещения по наклонным направляющим. Хорошая амортизация ствола при накате и откате и сравнительно небольшие габариты достигаются существенным усложнением конструкции. Известно автоматическое стрелковое оружие по патенту RU,Known automatic firearms according to patent RU, 2241940, class. F41A 3/54, 2004, in which the barrel is installed in the guide rails of the box with the ability to roll and roll back. The free movement of the barrel is prevented by friction in the contact surfaces of the barrel and receiver. Friction increases as surfaces wear and especially when small solid particles, such as sand, get into the gap. Known firearms according to patent RU, 2258883, cl. F41A 21/36, 2005, in which the barrel is mounted in a receiver containing a shock-absorbing device in the form of a packet of axially movable rings having the possibility of mutual movement along inclined guides. Good depreciation of the barrel during rollback and rollback and relatively small dimensions are achieved by a significant complication of the design. Known automatic small arms patent RU,
2064152, KЛ.F41A 5/06, 1976г., наиболее близкое к заявляемому по числу совпадающих признаков, в котором ствол установлен в стволы-юй коробке в подвижной относительно ствола опоре. Опора выполнена в виде подшипника качения в обойме, закрепленной на стволы-юй коробке в плоскости, перпендикулярной продольной оси ствола. Подшипник обеспечивает свободное вращение ствола вокруг оси в момент и после выстрела.2064152, KL.F41A 5/06, 1976, which is closest to the claimed one according to the number of matching features, in which the barrel is installed in the trunk of a box in a support movable relative to the barrel. The support is made in the form of a rolling bearing in a cage fixed to the trunks of the box in a plane perpendicular to the longitudinal axis of the barrel. The bearing provides free rotation of the barrel around the axis at the time and after the shot.
Настоящее изобретение решает задачу создания надежного в эксплуатации и несложного в изготовлении стрелкового оружия с подвижным стволом, закрепленным в стволы-юй коробке с обеспечением свободного хода при откате и накате ствола в направлении его продольной оси. Задача решается тем, что в стрелковом оружии, содержащем ствол, установленный в ствольной коробке, выполнены как минимум две, опоры, каждая из опор содержит обойму и по меньшей мере один подвижный элемент, размещенный в обойме с возможностью вращения и ограниченного перемещения вдоль продольной оси ствола, при этом в ствольной коробке выполнена подпружиненная опорная площадка под подвижный элемент. Подвижные элементы каждой из опор могут быть выполнены в количестве трех, равномерно расположенных в обойме в перпендикулярной оси ствола плоскости. Подвижный элемент может быть выполнен в форме шарика либо ролика.The present invention solves the problem of creating reliable in operation and not complicated in the manufacture of small arms with a movable barrel fixed in the trunks of the box with free movement during rollback and roll of the barrel in the direction of its longitudinal axis. The problem is solved in that in small arms containing a barrel mounted in the receiver, at least two supports are made, each of the supports contains a clip and at least one movable element placed in the clip with the possibility of rotation and limited movement along the longitudinal axis of the barrel while the receiver has a spring-loaded support platform for a movable element. The movable elements of each of the supports can be made in the amount of three, evenly spaced in a cage in the plane perpendicular to the axis of the barrel. The movable element can be made in the form of a ball or roller.
Опоры с подвижными в направлении наката и отката ствола элементами обеспечивают достаточный зазор между поверхностями ствола и ствольной коробки с тем, чтобы трение между поверхностями было минимальным, что обеспечивает надежность оружия даже в жестких условиях эксплуатации.Supports with moving elements in the direction of rollback and rollback of the barrel provide sufficient clearance between the surfaces of the barrel and the receiver so that the friction between the surfaces is minimal, which ensures the reliability of the weapon even in harsh operating conditions.
Изобретение поясняется описанием и приложенными к нему чертежами. На фиг.l представлен ствол в опорах без ствольной коробки; на фиг.2 и фиг.З - поперечный разрез ствола и жестко связанной с ним опоры с подвижными элементами различной формы; на фиг.4 и фиг.5 -поперечный разрез ствола и ствольной коробки с жестко связанной с ней обоймой и подвижными элементами различной формы; на фиг.б и фиг.7 -поперечный разрез ствола в ствольной коробке с подпружиненным подвижным элементом.The invention is illustrated by the description and the accompanying drawings. Figure l presents the barrel in the supports without a receiver; in Fig.2 and Fig.Z - a cross section of the trunk and rigidly connected supports with movable elements of various shapes; figure 4 and figure 5 is a transverse section of the barrel and receiver with a rigidly connected clip and movable elements of various shapes; on figb and Fig.7 is a transverse section of the barrel in the receiver with a spring-loaded movable element.
Устройство содержит ствол 1, установленный в ствольной коробке 2 в опорах 3. Каждая из опор содержит обойму 4, жестко связанную (выполненную заодно либо закрепленную) со стволом. В обойме равномерно по окружности установлены с возможностью вращения и одновременного ограниченного перемещения вдоль продольной оси ствола подвижные элементы, выполненные в форме шариiсов 5 либо роликов б, для чего в поверхности обоймы выполнены выемки соответственно 7 и 8, ответные по форме подвижным элементам. Обойма опоры может быть жестко связана (выполнена заодно либо закреплена) с внутренней поверхности ствольной коробки. Один из элементов опоры, размещенный в обойме, закрепленной на стволе, подпружинен относительно ствольной коробки пружиной: цилиндрической 9 или пластинчатой 10. Для надежности подпружинивания под подвижный элемент выполнена опорная площадка 11, размещенная в специальном «кapмaнe» ствольной коробки.The device comprises a barrel 1, mounted in the receiver 2 in the supports 3. Each of the supports contains a clip 4, rigidly connected (made at the same time or fixed) with the barrel. In the cage, movable elements made in the form of balls 5 or rollers b are mounted uniformly around the circumference with the possibility of rotation and simultaneous limited movement along the longitudinal axis of the barrel, for which recesses 7 and 8 are made in the surface of the cage, corresponding in shape to the movable elements. The support clip can be rigidly connected (made at the same time or fixed) with the inner surface of the receiver. One of the support elements, placed in a holder mounted on the barrel, is spring loaded relative to the receiver by a spring: cylindrical 9 or plate 10. For reliability of springing under the movable element, a support platform 11 is placed, which is placed in a special “pocket” of the receiver.
Устройство работает следующим образом. При накате и откате ствола в процессе стрельбы из стрелкового оружия он движется в опорах. При этом взаимодействие поверхностей ствола и ствольной коробки осуществляется посредством подвижных элементов, перемещающихся в обойме в пределах, определяемых ходом ствола. За счет зазора, обеспечиваемого опорами, уменьшается трение, улучшаются параметры стрельбы и повышается живучесть ствола и оружия в целом.The device operates as follows. During the rollback and rollback of the barrel in the process of firing from small arms, it moves in supports. In this case, the interaction of the surfaces of the barrel and the receiver is carried out by means of movable elements moving in the holder within the limits determined by the course of the barrel. Due to the clearance provided by the supports, friction is reduced, shooting parameters are improved, and the survivability of the barrel and weapon as a whole is increased.
Изобретение может быть использовано в стрелковом оружии с подвижным стволом для улучшения показателей стрельбы. The invention can be used in small arms with a moving barrel to improve shooting performance.
