Description

The claimed technical solution relates to military equipment, in particular to the design of an automatic weapon loading device. At present, the problem of placing the maximum number of unitary rounds for automatic guns in the minimum dimensions of the fighting compartment with a high rate of fire is urgent.

Known domestic tanks T-72, T-80 and T-90, which are equipped with an automatic loading device located in the tower at the bottom of the tank, equipped with a carousel-type conveyor and equipped with mechanisms for lifting and sending shots [1]. Cassettes for storing shots are evenly installed on the frame of the carousel-type conveyor.

However, such a given solution is difficult to implement for unitary shots and has a number of disadvantages, namely

in view of the fact that unitary shots are long compared to separate-case loading, and it is also necessary to ensure the rate of fire at the elevation angles of the automatic anti-aircraft gun from -5 to 75 degrees - there was a problem with the placement of the feed system as a whole within the dimensions of the BMP chassis- 3;

in the automatic loader of the T-72, T-80 and T-90 tanks, the shell and the sleeve are picked up by separate mechanisms for lifting and sending shots, which increases the loading time and introduces additional mechanisms into the shot feed system (design complication).

There is also a design solution for an automatic loader with unitary 125-mm rounds [2]. In this solution, the automatic loader is made in the form of an annular ammunition rack with lifting mechanisms. The characteristic features of this automatic loader are shortened cassettes, hingedly mounted on the frame of the ammunition rack, the connection of the working body of the cassette lifting mechanism with the rammer chain, and the installation of an intermediate tray on the gun. The proposed design of an automatic loading device with a ring stacking of unitary shots makes it possible to increase the loading rate by increasing the chambering speed and the proportion of combined operations, to simplify the arrangement of cassettes, locks and the automatic loading device as a whole.

However, the above version also has an additional tray lifting mechanism, which leads to an increase in the charging time.

This technical solution, as the closest to the problem being solved, was chosen as a prototype.

The technical task of the proposed utility model is to place the maximum possible number of unitary rounds in the limited space of the fighting compartment.

The specified problem is solved with the help of the technical result from the use of the claimed utility model, which consists in the use of a compact and simple design of the shot feed mechanism.

The claimed utility model offers a variant of an automatic loading device in the form of a horizontally located carousel-type ammunition rack, the composition of which includes the required number of trays with unitary shots placed in them.

A characteristic feature of the claimed utility model is the elimination of an additional drive for lifting the tray due to the introduction of simple kinematic elements directly into the rotating part of the carousel ammunition rack. This problem is solved by using the elements for lifting the tray, made in the form of levers, connected at one end through an axis with brackets, which are rigidly fixed to the rotating part of the automatic loader. At the other end, the levers are connected via an axle to the trays. The trays, on the other hand, are connected to the carriages, which, in turn, can move along the guides in the longitudinal direction. The position of the carriages in the longitudinal direction is set by a copier, which is fixed on the stationary part of the automatic loader in the form of a platform. The guides are rigidly connected to the rotating part of the automatic loader. The number of similar parts of the lifting mechanisms is equal to the number of trays. The rotating part is installed on a ball-and-slewing device of the lower platform. The transmission of torque to the rotating part occurs through the gear ring of the rotary bearing from the motor-reducer.

The specified technical result in the proposed design is achieved by the fact that when turning the carousel stacking, namely turning the trays in the radial direction, there is a gradual rotation of the trays relative to the horizon to the ramming line to the next loading mechanism (elevator).

The claimed utility model is illustrated by a diagram (Fig. 1, Fig. 2), which shows a functional diagram of the device. The proposed automatic loader contains Lever 1;

Unitary shot tray 2;

Bracket 3;

Carriage 4;

Guide 5;

Copier 6;

The rotating part of the automatic loader 7;

The fixed part of the automatic loader 8;

Gear ring 9;

Roller 10;

Axis 11.

The claimed utility model works as follows:

When turning the rotating part 7, the trays 2 are rotated in the radial direction by a "feed" step equal to n degrees (where n = 360 / the number of shots in the ammunition rack). At the same time, there is an interaction through the roller 10 of the carriages 4 with the copier 6. The copier 6 is made in such a way as to drive the carriage 4 towards the center of rotation of the supporting-rotary device for the required number of "feed steps" at the ramming angle, and then the movement of the carriage 4 from the center. The sector, in which the movement of the carriages 4 begins to the center and from the center, takes about half of the revolution of the rotating part 7 of the automatic loader. When the carriages 4 move to the center through the levers 1, the trays 2 rotate around the axes 11 connecting the trays 2 with the carriages 4. Thus, with a gradual rotation of the trays 2 in the radial direction, the trays 2 gradually rotate relative to the horizon, as a result of which the spatial position changes shot installed in tray 2 for its further delivery to the next mechanism.

The use of the proposed utility model has the following advantages:

in this carousel installation it was possible to accommodate the maximum number of trays within a small diametrical dimension;

lack of an additional drive for lifting the shot;

reduction of loading time, since the shot immediately approaches the elevator raised;

the ability to quickly change the type of shots;

the possibility of additional replenishment with shots of the proposed automatic loader directly from above into the tray;

due to the gradual rise of shots, the proposed automatic loader consumes much less power compared to the prototype with an additional drive.

The proposed technical solution made it possible to solve the problem of placing an uninhabited fighting compartment with a 57-mm automatic anti-aircraft gun of high ballistics in the dimensions of the BMP-3 chassis.

The use of the proposed technical solution in the design made it possible to place a large number of unitary shots in the minimum dimensions of the chassis, ensuring a high rate of fire of an automatic anti-aircraft gun at guidance angles from -5 radians to 75 degrees.

The applied technical solution made it possible to organize a system for feeding unitary 57-mm shots from a horizontally located operational ammunition rack of a carousel type to the dispensing line to the next loading mechanism (elevator). The use of the proposed technical solution allows the shot to be brought up simultaneously with the rotation of the carousel and raising the shot by the angle of loading (72 degrees) in a short time (0.3 s).
