Description

TECHNICAL FIELD OF THE INVENTION This invention relates to an actuation mechanism for a single-barreled gun, and more particularly to a gun ammunition feeding system that involves a rotary actuation mechanism that can be driven by a rear seat.

PRIOR ART In a conventional single-barrel gun operated by a rear seat with a high rate of fire, most of the reaction to the forward motion of the projectile and propellant gases is carried out by the rear barrel in one relatively As a short-lived shock,
It is transmitted to the sole. The bolt was thrown behind the gun,
It then rebounds forward to its firing position, extracting the bullet from the feeding mechanism. The position and time coordinates of the moving mass are not reliably controlled. Much of the reaction energy is transferred to the gun housing or breech, and from there to the gun breech. This reaction energy can be a disaster for vehicles that cannot absorb the force of large impacts. To withstand large shock loads of short duration requires a sturdy structure.

Typically, the feeders in such guns are operated intermittently and are only driven during a short portion of the gun cycle, thereby subjecting the ammunition feeder to high peak loads.

Solutions to this have been proposed in the past.
An externally powered rotary actuation mechanism is described in U.S. Pat. No. 125,563, issued April 9, 1877. More recent conventional rotary actuation mechanisms are disclosed, for example, in U.S. Pat. No. 2,849,921;
Described in No. 3380343. A gas-powered rotary actuation mechanism is described in U.S. Pat. No. 1,786,207 in which a feeder operated by a rear seat
It is described in GM Chin's book ``The Machine Gun'', volume 245, published by the Department of the Navy in 1955.

Purpose of the Invention Therefore, the purpose of the present invention is to provide an operating mechanism for a single-barreled gun operated by a rear seat with a high rate of fire: (a) to reliably control the time and position of all moving parts; The transmission and return of energy from the moving mass to the storage spring is reliably controlled; (c) the peak load on the main moving parts is small, resulting in low energy loss; and (d) the velocity of the bullet taken out from the ammunition feeding device is approximately constant. Overall, it is lightweight, simple, well-balanced, and
To provide a single barrel ammunition feeder with a high rate of fire operated by a reliable rear seat.

SUMMARY OF THE INVENTION A feature of the invention is the provision of a gun ammunition feeder having a single barrel and a rotary actuation mechanism that is symmetrical about the longitudinal axis of the barrel.

10 and enters the rear inner hole 126. A pin 136 passes through a lateral hole in the shaft 134 and the body and a slot in the head, securing these parts while allowing some relative rotation of the head with respect to the body. A firing pin 138 is disposed within the bore 128 and a transverse actuation arm 140 is secured thereto, which actuation arm is connected to the slot 130 and the body 1.

The slide 162 has a rear cam follower roller 166 that engages the cam track 148 of the rear rotor 24 and a front cam drive roller 168 that engages the cam track 146 of the gun bolt.

(Rear Rotor 24) As is clear from FIG. 9, a recess 170 is provided on the outer surface of the rear rotor 24, and a shoulder 172 is formed. A solenoid 174 is fixed to the main housing 10, and its armature 176 is connected to the main housing 10.
) is coupled to the dog 178 via a slot.
The dog 178 is pivotally mounted to the inner wall of the main housing and biased toward the rear rotor 24 by a helical compression spring 180. The dog can be provided as a toggle to reduce the force required from the solenoid.

(Operating Arm 200 and Locking and Unlocking) The barrel 68 has a rifling hole 182 and a chamber 184. A cavity 186 in which the barrel extension 60 is adapted to receive the forward portion 116 of the bolt head 72.
and a plurality of grooves 188 through which the lock pieces 118 pass. The rear end of the pillar 190 is fixed to the back plate 22.
A helical bolt return spring 192 is wound around the pillar 190 and inserted into the hole 114 of the bolt.
It is captured between the back plate 22 and the disk 132.
When the bolt head 72 is in the unlocked, ready-to-fire position (i.e., the firing pin actuation arm is positioned on the rear surface 194 of the inwardly directed projection 196 of the housing, which acts as a barb).
), the firing pin spring 144 is compressed. When the bolt head 72 is fully rotated to the locked position, the firing pin actuating arm disengages from the barb and the firing pin 138 is biased forward by the firing pin spring 144. The gun bolt 74 has a pair of slides 107 extending from the body 102 and resting on the track 64, and an actuation arm 200 extending laterally from the front portion 116 of the bolt head (Nos. 10A-11B).
figure). The actuation arm 200 has a cam follower surface 202 that rotates the cam 20 in a counterclockwise direction when in the unlocked, ready-to-fire position, as seen in FIG.
4 acts on this cam driven surface 202. Cam 204 is fixed to shaft 206 and rotates at non-uniform speeds, one revolution per gun cycle, to pivot actuating arm 200 clockwise (i.e., 11B).
10B) and lock it. The actuating arm 200 has another cam follower surface 208 which, when in the locked position in the ready-to-fire position, as well as when moving rearwardly in the rear seat, has a cam follower surface 208 which is attached to the cam follower surface 208 of a protrusion fixed to the housing. The arm 2 is
00 counterclockwise to unlock (ie, rotate from Figure 10B to the state of Figure 11B).

Cam tracks 96/98, 146 and 148 do not have uniform pitch angles. In order to eliminate the risk of the cam rollers and the cam track being blocked without being driven, the pitch angle of the cam track should be kept below 51°, preferably below 45°. If the diameter of the rear rotor 24 is large enough, the pitch angle of the raceway 146 can be 0°. That is, it may be a simple ring. However, when the diameter of the rear rotor 24 is small, the orbit 14
In order to keep the pitch angle of 8 small, the track 146 is given a considerable pitch angle. At this time, orbit 96/
98, the effective pitch angle of the combination of trajectories 146 and 148 must be considered. During the initial portion of movement of the barrel extension 60 by the rear seat, the effective pitch angle of the combination of tracks 146 and 148 is equal to that of tracks 96/98 until the gun bolt 74 is unlocked by the ramp 210. must be the same as the pitch angle (because bolt 74 and barrel extension 60
This is because they move backward as a unit. ). After the gun bolt 74 is unlocked, the effective pitch angle of the combination of tracks 146 and 148 is relatively greater than the pitch angle of the tracks 96/98, causing the rearward movement of the barrel extension 60 to be more rapid. Rearward movement of the bolt 74, i.e. the bolt 7 of the gun relative to the barrel extension 60
(In other words, after unlocking, the bolt 74 moves rearward faster than the barrel extension 60, and the two separate. See FIG. 2 for details.)

(Operation of Gun Mechanism) The gun mechanism described above operates as follows. The gun is in a ready-to-fire position with bullet R1 locked in chamber 184 and energizing solenoid 174, as shown in FIG. When the cam 204 drives the head of the bolt to the fully locked position, the firing pin actuating arm 140 disengages from the barb face 194 and the spring 144 drives the firing pin 138 to fire the bullet. The gun barrel 68 was destroyed by the explosion.
and the barrel extension 60 seats rearwardly with the gun bolt 74 locked thereto. When the gun bolt 74 moves rearward, the cam follower surface 208 moves toward the inclined surface 210.
Then, unlock the head 72 of the bolt. As the barrel extension 60 moves rearward, the cam tracks 96,9
8 drive cam driven rollers 92 and 94, respectively, to rotate the front rotor 32 and its gear ring portion 50.
The gear ring 50 drives the gear ring 48 of the connecting shaft 42, which rotates the gear ring 52 of the connecting shaft via the connecting shaft 42, thus rotating the gear ring 54 and the rear rotor 24. When the rear rotor 24 rotates together with the slider 162, the fixed cam track 14
8 drives the cam driven roller 166 rearward, thus driving the sliding body 162 and the front cam driving roller 168. The front cam drive roller 168 is the bolt 74 of the gun.
At the same time, the bolt cam track 146 is driven rearward. A slide 162 accelerates the rearward movement of the gun bolt 74 relative to the barrel extension 60, as shown in FIG. As barrel 68 and bolt 74 move rearward, they compress barrel return spring 84 and bolt return spring 192, respectively. Barrel return spring 84 is 180
The gun barrel 68 is returned to the firing preparation position before . The fired cartridge is thrown sideways.

To fire another bullet, the rotor rotates across the 180° trailing rest of the bolt 74 (when the bolt's longitudinal velocity is zero), throwing the fired cartridge laterally. During this period, a new cartridge is fed laterally. Bottom return spring 19
2 drives the bolt 74 forward with a new cartridge, inserts the head 72 of the bolt into the rear bore 70, and loads the cartridge. Actuation arm 140 hits rear surface 194 and compresses firing pin spring 144. The shaft 206 rotates counterclockwise and the cam 20
4 and pivot the actuating arm 200 to rotate the bolt head to the locking position.

If you do not want to fire another bullet, solenoid 17
4, so that the compression spring 180 compresses the shoulder 172.
The dog 178 is biased so as to grip the rear rotor 24, and the rotation of the rear rotor 24 is stopped. The front rotor 32 , which is connected to the rear rotor 24 by the connecting shaft 42 , continues to rotate, but due to its inertia as well as the connecting shaft 42 .
The barrel extension 60 is in the firing ready position. The wedging action of the cam tracks 96, 98 prevents reverse movement of the rollers 92, 94 and reverse rotation of the front rotor 32. The device thus stops in the loaded state with the connecting shaft 42 under torsional stress.

Thereafter, when the solenoid 174 is energized, the torsion of the connecting shaft 42 is released, thereby accelerating the rear rotor 24 and releasing the bolt return spring 192 from the bolt 7.
4 can be driven into the chamber 84 and locked. To initially load the gun, the front rotor 32 is rotated by an external power source. At this time, the cam rollers 92 and 94 move within the annular cam track 100.

(Mechanism and Operation of Ammunition Supply Device) When the gun is stationary at the rear of the bolt, the ammunition supply device feeds one bullet between the extraction pieces 122 of the bolt 74 and ejects the already fired cartridge case. The feeding device is driven by a connecting shaft 42, which connects the front rotor 3
2.

The connecting shaft 4 has a first intermediate gear 201 and a second intermediate sun gear 402. A second intermediate sun gear 402 meshes with a pair of planetary gears 404 . The planetary gears 404 are each pivotally supported by a spider 406, and mesh with a fixed ring gear 408, respectively. spider 40
6 has an annular sun gear 410, which meshes with a pair of planetary gears 212. The planetary gears 212 are each pivotally supported by a spider 214, and each fixed annular gear 4
It meshes with 08. This planetary gear system has a 16:1 reduction. A spider 214 is integral with a tubular shaft 216 coaxial with coupling shaft 42 .

A front peel-off sprocket 218 and a rear peel-off sprocket 220 are secured to the annular shaft 216. Peeling sprocket 218, 220
is the first bullet R2 in the row of bullets with bullets (a bullet is a small metal ring that connects each bullet)
(FIG. 5), and this row is connected to the bullet retainer positioning device 222, the front outer bullet guide portion 224, 224.
A, the bullet is passed through the rear outer bullet guide portions 226, 226A, the front peeling guide portion 228, and the rear peeling guide portion 230, and each bullet is sequentially peeled off and fed from each bullet. Each rip-off sprocket has four crescent-shaped sections, each with a speed of 1/
It rotates at a substantially uniform speed of 4.

The gear 201 (FIGS. 1 and 7) is the reduction gear 23
It meshes with 2. This reduction gear is fixed to rotate together with an elliptical gear 234 (FIG. 7), which meshes with an elliptical gear 236 (FIG. 7). The idler gear 238 is fixed to the shaft 206
(Fig. 3, Fig. 5) meshes with a gear 240 fixed thereto. For this reason, the feed shaft rotates once per gun cycle at a sinusoidal, ie non-uniform speed.
As previously mentioned, shaft 206 supports cam 204. A front infeed sprocket 242 and a rear infeed sprocket 244 (FIG. 5) are fixed to the shaft 206.

Gear 201 also meshes with planetary gear 246 (FIG. 7). A planetary gear 246 is fixed to rotate with an elliptical gear 250 at a gear 248 (FIG. 7).
The oval gear 250 (Fig. 7) meshes with the oval gear 252 (Fig. 7), the oval gear 252 is fixed to rotate together with the gear 254 (Fig. 7), and the gear 254 is It meshes with a gear 256 fixed to an output shaft 258. A forward forward dispensing lever 260 (FIG. 5) and a rear delayed dispensing lever 262 (FIG. 5) are fixed to the dispensing shaft 258.

In operation, as shown in FIG. 5, the stripping sprockets 218, 220 rotate counterclockwise at a substantially uniform speed to continuously pull a train of bullets into the feeder at a substantially uniform speed. Stake it out, tear off the first bullet, and send it in. The stripped bullet is guided onto the inner surfaces of the stripping guides 228, 230 and their extensions. The stripping sprockets 218, 220 deliver the bullet into the crescent-shaped portions of the now substantially stationary feed sprockets 242, 244 (which rotate at non-uniform speeds), and the bullet is now substantially stationary. The feed and discharge levers 260 and 262 are substantially in a stopped state.
It is held there by the end of the . gun bolt 74
When the lever reaches the rear stop, the delayed discharge lever 2
60, 262 rotates counterclockwise to move the fired cartridge across the bolt surface 120 and into the extractor piece 122.
It is swept out along the dispensing guide paths 264 and 266. At the same time, the infeed sprockets 242, 244
rotates clockwise to advance a new bullet along the extension of the feed guideway to the bolt surface 120, across the bolt surface to the extractor piece 122, and then continues for one cycle. delayed discharge levers 260, 2 which rotate to receive the next delivered bullet from the stripping sprockets 218, 220;
The trailing edge of the 62 prevents the bullet from tipping on the bolt surface, and when the bolt is forward, these levers continue to rotate out of its path, rotate for a full cycle, and then The bullets delivered to the feed sprockets 242 and 244 are held there.

In this way, the front and rear infeed sprockets 2
Since the shafts 206 of 42, 244 and the dispensing shafts 258 of the front and rear delayed dispensing levers 260, 262 rotate at non-uniform rotational speeds, the The bullet can be sent in and the sprockets 242, 244 can reliably receive it and advance it to the bolt surface,
Also, the ejection levers 260, 262 can temporarily hold the bullet forward to the bolt surface and eject the fired cartridge case.
