Description

Anti-recoil device of artillery

Technical Field

The utility model belongs to weaponry development field, concretely relates to anti-recoil device of artillery.

Background

The anti-recoil device, known as the "heart" of the artillery, is a significant revolution in the technological development history of artillery. The recoil device connects the gun body and the gun rack, and the recoil movement of the gun body reduces the force of hundreds of tons acting on the gun body to dozens of tons acting on the gun rack, so that the gun power is very large, but the gun rack can be very light, and the contradiction between the gun power and the maneuverability is greatly relieved.

Structurally, the anti-squat device comprises three, in particular 3, basic components. The first function is that the recoil energy is consumed when the gun body recoils, so that the gun body recoils for a certain distance and stops, and the function is completed by a recoil brake; the second function is to store energy when the gun body sits backwards, and push the gun body forwards to enable the gun body to re-advance to the position after the gun body sits backwards and stops, and the function is finished by a re-advancing machine; the third function is that the gun body consumes energy when in recoil, so that the gun body stops when in recoil, and the function is finished by a recoil controller. The domestic artillery generally combines a recoil brake and a re-advancing check brake together to form a parking machine, and the re-advancing check is placed independently; the united states, et al, is accustomed to combining 3 basic components together, known as a stationary recoil machine. However combined, the 3 basic components of the anti-recoil device are absent and all together perform the three functions of the anti-recoil device.

No matter the form of adopting parking machine and recoil machine, or adopt the form of parking recoil machine, the anti recoil device of present artillery all has a problem: connect gun body and re-advancing machine (the machine of stopping back is one with the re-advancing machine through the connecting rod, and all dispose in gun body side), the line of action of force that anti recoil device produced this moment is a section distance of staggering always with bore axis (barrel recoil and re-advancing direction of motion), this is when gun recoil and re-advancing, can arouse the torsion of gun rack, leads to the line of sight skew, is unfavorable for the continuous shooting of gun, especially sets up under the less reasonable condition (like soil flaccidity) at the hoe that stops, this kind of condition can be more outstanding.

The working principle is as follows: when the gun is fired, the gunpowder gas pushes the projectile forward, and simultaneously, an acting force (bore resultant force) which is backward along the axis of the bore is given to the gun body, the bore resultant force pushes the gun body to sit backward, the gun body drives the gun tail and the parking cylinder and the re-advancing cylinder which are fixed on the gun tail to sit backward relative to the respective parking rod and the re-advancing rod, in the process of the recoil, the parking machine generates resistance and consumes energy, and the re-advancing machine stores energy; when the gun sits backwards to a certain distance, the recoil machine stops, releases energy, pulls the gun tail and the barrel to recoil forwards, and the parking machine (sometimes also comprising the recoil machine with the recoil valve) generates resistance to consume energy, so that the gun can recoil to the position stably. It should be noted that, in the recoil and recoil processes, the main power and the restraint reaction force both pass through the axis of the bore (the friction force of the cradle caused by the gravity component of the recoil part is small and can be approximately ignored), so that the torsion of the cradle can be well prevented, and the continuous shooting precision of the artillery is improved.
