IMPLEMENTATION OF THE USEFUL MODEL

The proposed utility model is illustrated by a specific example of implementation, which, however, is not the only possible one, but clearly demonstrates the achievement of a given set of essential features of a given technical result.

FIG. 1 shows the following parts and elements of the proposed loose cartridge tape:

1 - an element of engagement in the form of a hook;

2 - jumper;

3 - front removable element;

4 - rear removable element;

5 - differentiated thickness;

6 - front paws of girth;

7 - hind legs of girth.

A loose ammunition belt for automatic weapons containing machine-gun links arranged in series and interconnected. The link is a body made of lightweight plastic, physicomechanical characteristics are not inferior to metal of a similar purpose, to connect to each other, each machine-gun link has an engaging element in the form of a hook 1 on one side, and on the opposite side a window bounded by a jumper 2, for placing a hook of an adjacent link in it when it engages with a jumper, each machine-gun link is equipped with a reinforced front 3 and a reinforced rear 4 removable element, which also serves to fix the machine-gun link on the cartridge, while to give rigidity along the entire length of the cartridge belt link has a differentiated thickness 5 , the machine-gun link is fixed on the cartridge using the front 6 and rear paws of the girth 7. The links of the loose cartridge belt are made of polycarbonate.

The proposed loose cartridge tape works as follows.

Before direct operation, the loose cartridge tape is loaded with cartridges (Fig. 3). When collecting the cartridge belt, the cartridges are placed in links and fixed by the front and rear legs 6 and rear 7 and additionally secured by the rear removable element 3, which also performs the function of removing the cartridge link from the belt due to the design of the removable mechanism of the machine gun. To connect to each other, each machine-gun link has an engaging element in the form of a hook 1 on one side, and on the opposite side a window bounded by a bridge 2 for placing a hook of an adjacent link in it when it engages with the bridge.

The assembled loose ammunition tape is installed in the machine gun and firing is carried out. In this case, after the shot, the cartridge case is separated from the links of the loose cartridge tape using the front 3 and rear 4 removable elements. The opening of the cartridge strip occurs automatically after the shot, since the engaging element in the form of a hook 1 is freely disconnected from the bridge 2 under the action of the forces arising during firing. Detached links of loose ammunition tape are removed outside the machine gun, i.e. the cartridge strip is scattered.

Developed, manufactured, tested an experimental loose cartridge tape for a standard cartridge of 12.7 mm caliber (Fig. 3). A complex of laboratory experimental studies was carried out to determine the strength, stiffness and performance of a loose cartridge belt under normal conditions, as well as at -50 and +50 degrees Celsius with a friction coefficient in the range of 0.02-0.05, an uninterrupted supply of cartridges for a shot, ease of sliding was recorded , ease of feeding (figure 4) and high strength and stiffness. During the tests (Fig. 5), the links flew out without hindrance, without creating conditions for jamming the machine gun during firing. The strength and rigidity of the machine-gun link of the cartridge belt was tested in a number of static and dynamic experiments. The link was subjected to tensile tests. The breaking load, which the links withstood at the joints, exceeded 25 kg. It is worth noting that the strength and stiffness of the machine gun belt link will vary greatly depending on the method of making the plastic link. When casting the links of a cartridge strip, the rigidity will be an order of magnitude higher than when making links using 3D printing.

In addition, preliminary field tests in various modes of fire gave positive results (Fig. 6).

The loose cartridge belt for automatic weapons proposed for patenting has a simple design, does not create difficulties for moving around the battlefield, has comparable strength and rigidity with similar indicators of the links of a cartridge belt made of metal, despite the fact that the links of a machine-gun belt made of polycarbonate are several times lighter ...

Thus, the specified technical result is achieved due to the formulated essential features, clearly presented below:

- sequentially located and interconnected machine-gun links; the link is a body made of lightweight plastic, which is not inferior in physical and mechanical characteristics to metal of a similar purpose;

- to connect to each other, each machine-gun link has on one side an engaging element in the form of a hook 1, and on the opposite side a window bounded by a bridge 2 for placing a hook of an adjacent link in it when it engages with the bridge;

- each machine-gun link is equipped with a reinforced front 3 and a reinforced rear 4 removable element, which serves to fix the machine-gun link on the cartridge;

- in this case, to impart rigidity along the entire length of the cartridge belt link has a differentiated thickness 5;

- the machine-gun link is fixed on the cartridge using the front 6 and hind legs of the girth 7.

An example of a specific implementation is shown in FIG. 7. Loose ammunition tape was developed, in particular, for the YakB 12.7 multi-barreled automatic aircraft machine gun, in which a special mechanism is used to remove the machine-gun link from the sleeve, which consists of two guides along which the link is removed from the sleeve and separated from liners, protrusion 8 18 mm wide and 33 mm long corresponds to a special groove in the machine-gun belt feed device in the YakB 12.7 aircraft rapid-fire machine gun.

The utility model is a classic-type machine-gun link for a rapid-fire machine gun. The utility model differs from the classic execution of the machine-gun link in the material of manufacture and design features. The material of the utility model was chosen from lightweight plastics, in the particular case from polycarbonate. The model of the machine-gun link has thickenings to make it more rigid. The machine-gun link experiences the greatest loads during the operation of the machine gun and the supply of a cartridge to the machine gun, as well as during the operation of the rotation mechanism in the machine gun box. Consequently, the most vulnerable points of the machine-gun link are the places of contact with the elements of the machine gun and the places where one link is connected to another. To compensate for the loads, the link thickness was increased by 1 mm and reinforcing elements were added. On the longitudinal part of the machine-gun link on the side opposite to the fitting of the cartridge with the link at a distance of 5 mm from the edge of the front removable element, an additional thickening is added with a width of 18 mm and a length of 33 mm. From it, thickening elements were also added to the elements of gripping and connecting two machine-gun links in the transverse direction. The element of connection of machine-gun links has a window of 17 × 8 mm. It is formed by means of a bridge, which is connected to the link body, the length of the bridge is 33 mm. Through which the two links are connected. A gripping element is placed in the window, which has the shape of a hook, the length of which is 15 mm. The machine-gun link at its edges has girth legs that fix the cartridge in the link. The width of the front legs along their entire length is 10 mm, when the hind legs have a width that varies from 10 mm at the base of the legs to 7.3 mm at the top. Their diameter is less than the outer diameters of the walls of the cartridge cone. The rear removable element also serves to fix the cartridge in the link using a special groove in the sleeve. The link height is 21.2 mm, the width is 37.2 mm, and the length is 84.8 mm.
