Description

[0001] DECOUPLING BEARING MODULE FOR GUIDED MISSILE [0002]

The present invention is a projectile, such as a shell capable of guided control, is installed between the control body and the body provided with a steering pin for the direction change, guided weapons to support the spin movement of the body by separating the control body from the spin movement of the body The present invention relates to a decoupling bearing module for use.

In general, there are two ways to control the direction of a projectile launched from a ground platform or artillery, which is a one-dimensional ballistic correction method that increases the aerodynamic resistance received by the projectile and appropriately reduces the range. There is a two-dimensional ballistic correction method that controls the angle of the canard or tailfin.

The method of controlling the direction of the projectile is mainly used two-dimensional ballistic correction method with excellent accuracy, a pair of fixed pins and a pair of control pins are radially symmetrically installed on the projectile for the flight and direction of the projectile. do.

The front wing of the projectile is called an ear wing or a canard, and the rear wing of the projectile is called a tail wing or a tail pin. For guided control of the projectile, either a canard or a tail fin can be installed or installed together, depending on what the projectile's main target is.

That is, whether the projectile is an anti-tank ground missile or an anti-aircraft surface-to-air missile determines whether the canad or the tail fin is installed, which may vary depending on whether the projectile is controlled in the subsonic region or the supersonic region. For example, the canard is easier to control the projectile's lift than the tail fins, so for land-based missiles in subsonic zones, it is better to install canards. Since the tail fin is better at exhibiting the maximum moment performance of the projectile than the canard, it is better to install the tail fin at the projectile for the surface-to-air missile in the supersonic zone.

FIG. 1 is a perspective view showing a general guided weapon projecting body, FIG. 2 is a side sectional view showing a bearing module for guided weapons according to the related art, and FIG. 3 is an enlarged view of 'A' in the embodiment of FIG.

1, a pair of the fixing pins 10 and a pair of the control pins 20 are connected to the projectile 1 for the purpose of flight and direction change of the projectile 1, such as the canard or tail pin, In a radially symmetrical manner. The projectile 1 includes a body 2 as shown in FIG. 1 and a control body 3 on which the fixing pin 10 and the control pin 20 are installed. Inside the drive unit (not shown) for controlling the angle of the control pin 20 is installed.

The pair of fixing pins 10 are fixed to the control body 3 as the name so as to separate the control body 3 from the spin movement of the body 2 using aerodynamic force when the projectile 1 is launched. And, the pair of control pins 20 are rotatably installed on the control body 3 serves to change the direction of the projectile (1).

Therefore, the body 2 and the manipulator 3 of the projectile 1 are coupled to each other through the bearing module 30 as shown in FIGS. 2 and 3, and are rotatably installed separately. That is, the bearing module 30 for guided weapon according to the prior art is installed between the steering body 3 having the control pin 20 for changing the direction of the projectile 1 and the body 2 for spin movement. The steering body 3 is separated from the spin movement of the body 2 to support the spin movement of the body 2.

Looking at the configuration of the bearing module 30 according to the prior art in more detail, it extends in the longitudinal direction from one end of the steering body 3 to be inserted into the front end of the body 2 together with the steering body (3) The body 2 so as to correspond to the rotating shaft 31 to rotate, the pair of bearing inner ring 32 spaced apart from each other on the outer peripheral surface of the rotating shaft 31, and the pair of bearing inner ring 32, respectively A pair of bearing outer races 33, which are spaced apart from each other on the inner circumferential surface of the distal end of the pair, and a pair of rolling elements respectively inserted and rotated between the corresponding bearing inner races 32 and the bearing outer races 33, respectively. (34). In addition, the stator 35 is embedded in the outer circumferential surface of the rotating shaft 31 so as to be located between the pair of bearing inner ring 32, the coil is wound with a voltage formed by the magnetic force, and the pair of bearing outer ring ( The rotor 36 may further include a rotor 36 embedded in the inner circumferential surface of the distal end of the body 2 so as to be positioned between the rotors 2 and a permanent magnet that rotates together with the body 2 and forms a magnetic force. The stator 35 and the rotor 36 function as a generator for generating electric power by the spin motion of the body 2. [

In the case of the bearing module 30 according to the prior art of the above configuration, as shown in Figure 3 to support the spin movement of the body 2 by separating the control body 3 from the spin movement of the body 2 To this end, a minimum rotational interval G for rotation between both members is required between the front end face of the body 2 and the one end face of the steering body 3. This rotation interval (G) is for smoothing the separated spin movement between the body 2 and the steering body (3).

However, two fatal problems arise due to the rotation interval G between the front end face of the body 2 and the one end face of the steering body 3. First, when storing, transporting and installing the projectile 1, foreign matters or the like flows between the rotation intervals G to prevent rotation of the rolling element 33 or separate spins of the body 2 and the steering body 3. By limiting the movement, a serious error occurs in precise guided steering of the projectile 1.

Second, since the projectile 1 is subjected to an impact of 10,000 to 20,000 times the gravity acceleration from the platform or artillery when firing, the front end surface of the bullet body 2 and one end surface of the control body 3 collide with each other. The impact is concentrated on the pair of bearing outer ring 33, there is also a problem that the risk of damage is very high, leading to a situation where the guided steering of the projectile 1 is virtually impossible.

The object of the present invention devised to solve the above problems is to minimize the risk of damage by absorbing most of the launch impact generated during the launch of the projectile, the rotation between the carcass and the control when the projectile is stored, transported and mounted The present invention provides a decoupling bearing module for guided weapons, which is capable of smoothly separating spin motion between the body and the steering body while blocking the inflow of foreign substances at intervals.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments with reference to the accompanying drawings.

In order to achieve the above object, the decoupling bearing module for guided weapons according to the present invention is installed between a control body provided with a control pin for changing the direction of a projectile and a spinning body and the steering from the spin movement of the body. A decoupling bearing module for guided weapons that separates the body and supports the spin motion of the body, comprising: a rotating shaft extending in a longitudinal direction from one end of the body to be inserted into the front end of the body and rotating together with the body, A pair of bearing inner races spaced apart from each other on the outer circumferential surface of the rotary shaft, and a pair of bearing outer races spaced apart from each other on the inner circumferential surface of the distal end of the car body so as to correspond to the pair of bearing inner rings, respectively; A pair of rotations respectively inserted and rotated between the bearing inner ring and the bearing outer ring The main body and the front end face of the car body facing the one end face of the control body are coupled to and protruded on one of the front end face of the control body or the front end face of the car body so as not to come into contact with each other. It includes an annular plastic deformation ring that absorbs the launch impact of the projectile while plastic deformation when one end surface of the steering body and the front end surface of the car body is close.

In addition, an annular engaging groove recessed inwardly is formed on one of the one end surface or the front end surface of the car body, and the plastic deformation ring has one side inserted into and fixed to the coupling groove, and the other side thereof is It is characterized by plastic deformation by absorbing the launching impact of the projectile.

In addition, the plastic deformation ring is characterized in that the irregularities are formed on the other side.

In addition, the annular elastic deformation of the elastic material which is fixedly coupled to the inner peripheral surface of the front end of the body and is located between the pair of bearing outer ring, in contact with one side of the bearing outer ring of the pair of bearing outer ring to provide elastic force And an annular bearing stopper fixedly coupled to an inner circumferential surface of the distal end of the car body to be in contact with the other side of the outer ring of the bearing in contact with the elastic deformation ring to prevent the outer ring of the bearing from being separated.

In addition, the stator is embedded in the outer circumferential surface of the rotating shaft so as to be located between the pair of bearing inner ring, and the coil is wound around the pair of the outer ring of the bearing body, and the coil is wound around the pair of bearing outer ring. It is characterized in that it further comprises a rotor made of permanent magnets, which are embedded, and rotates together with the body to form a magnetic force.

Decoupling bearing module for guided weapons according to the present invention, through the plastic deformation ring is installed in the rotation interval between the front end surface of the body and the end surface of the control body, the first between the body and the control body during storage, transport and installation of the projectile It is possible to block the inflow of foreign substances at intervals at the source, and to minimize the risk of breakage by absorbing most of the launching impact while plastic deformation when the launching impact of the second projectile occurs. As plastic deformation occurs, a gap is generated between the front end face of the carcass and the end face of the control body, so that the separated spin motion between the car body and the control body can be smoothly performed.

Hereinafter, a preferred embodiment of a decoupling bearing module for guided weapons according to the present invention will be described in detail with reference to the accompanying drawings.

Decoupling bearing module for guided weapons according to the present invention, as shown in Figures 4 to 10, the steering body 3 is provided with a control pin 20 for changing the direction of the projectile (1) and the bullet body (2) The rotary shaft 100, the bearing inner ring 200, and the bearing outer ring (B) to separate the steering body 3 from the spin motion of the body 2 and support the spin motion of the body 2. 300, the rolling element 400 and the plastic deformation ring 500 may be further included, and further include a stator 910 and a rotor 920. In addition, the decoupling bearing module for guided weapons of the present invention may further include an elastically deformable ring 700 and a bearing stopper 800 as shown in FIGS.

First, a projectile 1 to which an induction decoupling bearing module of the present invention is applied is provided with a steering pin 20 for switching the direction of the projectile 1 on the front or rear of the body 2 A manipulator 3 is provided. When the pilot 3 is installed in front of the projectile 1 as shown in the figure, the pilot pin 20 is called an ear wing or a canard. When the pilot 3 is not shown in the drawing, 1, the steering pin 20 is referred to as a tail wing or a tail pin. Whether the control member 3 is disposed forward or rearward of the projectile 1 can be determined according to the main flying area or the target of the striking of the projectile 1 and the configuration and function of the control pin 20 are widely And detailed description thereof will be omitted.

In the projectile 1 having the above-described structure, the pilot 3 equipped with the pilot pin 20 must be free from the spinning motion of the torus 2 for changing the direction with respect to the traveling direction of the projectile 1 . To this end, the decoupling bearing module for guided weapons according to the present invention is installed between the body 2 and the manipulator 3.

At this time, with respect to the name of the present invention of a decoupling bearing module, it is assumed that decoupling is performed while the second coupling is realized while realizing the function as the first bearing, that is, 3) is disconnected from the connected state before the firing to the unconnected state after the firing. The features of the present invention will become more apparent from the detailed description of the respective constitutions described below and the operation and effect thereof.

The rotating shaft 100 is for connecting the body 2 and the steering body 3 to each other to perform separate spin movements, and to be inserted into the front end of the body 2 as shown in FIGS. 4 to 10. It extends longitudinally from one end of the steering body 3 and rotates with the steering body 3. In order to rotate the rotary shaft 100 together with the steering body 3, it means to be integrally formed with the steering body 3 or to be combined with one body as a separate part.

At this time, since the diameter of the rotating shaft 100 is smaller than the diameter of one end surface of the steering body 3, when the rotating shaft 100 is inserted into the front end of the body 2, the one end surface and the body 2 of the steering body (3). The leading end face of) comes into contact. However, if one end surface of the control body 3 and the front end surface of the body 2 are coupled in contact with each other, a minimum rotation interval G may be interfered with each other during the spin movement of the control body 3 and the body 2. ) Is required. Therefore, in the state where the rotation interval G is formed so that one end surface of the steering body 3 and the front end surface of the body 2 are formed, the bearing inner ring 200, the bearing outer ring 300, and the rolling element 400 to be described later. It will be able to support the spin movement of each of the carcass (2) and the steering (3).

That is, as shown in FIGS. 4 to 10, a pair of bearing inner rings 200 are provided so as to be spaced apart from each other on the outer circumferential surface of the rotating shaft 100, and a pair of bearing outer rings 300 is also provided with the pair of Each of the bearing inner ring 200 and the bearing outer ring are provided with a pair of rolling elements 400 which are mutually spaced apart from each other on the inner circumference of the distal end of the body 2 so as to correspond to the bearing inner ring 200, respectively. Inserted between the 300 and rotate. The rolling member 400 may be constituted by a plurality of balls as shown in the drawing, or may be a plurality of rollers, and may be extended to indicate a plane due to surface contact between the bearing inner ring 200 and the bearing outer ring 300 You may.

In other words, although the bearing inner ring 200, the bearing outer ring 300, and the rolling member 400 are referred to as the bearing inner ring 200 and the rolling inner ring 400, respectively, it is possible to use a ball bearing, a rolling bearing, or a flat bearing. The bearing inner ring 200 is coupled to the rotary shaft 100 and the bearing outer ring 300 is coupled to the body 2 to be inserted between the bearing inner ring 200 and the bearing outer ring 300, The body 2 and the manipulator 3 that rotates together with the rotary shaft 100 are in a state of being able to spin independently of each other.

As emphasized in the above-described problems of the prior art and the object of the present invention, the launching impact of the projectile 1 is impacted by 10,000 to 20,000 times the gravity acceleration, and as shown in FIG. 3. A launching shock is generated by the rotational interval G between the front end face of the body 2 and the one end face of the steering body 3. Naturally, the front end surface of the body 2 and the one end surface of the steering body 3 are in contact with each other to generate a large impact. At this time, the launching shock is transmitted to the bearing outer ring 300, so that the corresponding surface with the bearing inner ring 200 There is bound to cause a failure in the rotational movement of the rolling element 400. In addition, the rotational interval (G) formed between the front end surface of the body 2 and the one end surface of the steering body 3 can cause a serious blow to the rotational movement of the rolling element 400 by the inflow of foreign matters. Problems eventually interfere with precise guided steering of the projectile (1), causing the target to not hit correctly. Therefore, in the decoupling bearing module for guided weapons according to the present invention, the plastic deformation ring 500 described below is solved simply to solve the above problems.

The plastic deformation ring 500 has a ring shape as shown in FIGS. 4 to 10 so that the front end faces of the body 2 facing the one end face of the steering body 3 do not contact each other. It is coupled to one end surface of the (3) or one of the front end surface of the body 2, and protrudes, and through the launching impact of the projectile (1) of the one end surface of the control body 3 and the body 2 When the tip surface is close to the plastic deformation while absorbing the firing impact of the projectile (1).

For example, as shown in FIGS. 4 and 5, the plastic deformation ring 500 has one side coupled to one end surface of the steering body 3 and the other side protruding to be in contact with the front end surface of the body 2. It is a state. Through the plastic deformation ring 500, since the rotation interval (G) formed between the first end surface of the first control body 3 and the front end surface of the body 2 is closed, it is possible to prevent the inflow of foreign matter, Second, as shown in FIG. 6, plastic deformation is carried out by absorbing the launching impact of the projectile 1, and in the third plastic deformation state, a rotational interval G is formed between the control body 3 and the body 2 so that each is smooth. Allow spin motion to occur.

That is, the decoupling bearing module for guided weapons according to the present invention performs a bearing function through the bearing inner ring 200, the bearing outer ring 300 and the rolling member 400, And the pilot 3 are connected to each other before the launch vehicle 1 is launched. After the launching, the plastic deformation ring 500 is plastic-deformed and the spin of each of the body 2 and the pilot 3 is performed So that the connection is released.

Meanwhile, as shown in FIGS. 9 and 10, the plastic deformation ring 500 has one side coupled to the front end surface of the carbon body 2, and the other side protruding from the one end surface of the steering body 3. It may be in a state. However, it is preferable that the fixed engagement position of the plastic deformation ring 500 is coupled to one end surface of the control body 3 rather than the front end surface of the body 2. The reason for this is that the control member 3 has a main function to change the direction of the projectile 1 by driving the control pin 20 rather than to the spin motion but the toroidal body 2 has a high speed spin movement of about 18,000 times per minute This is because the plastic deformation ring 500 may be disengaged due to the high-speed spinning motion of the body 2 to be released.

In the case of the plastic deformation ring 500 as described above, if one side of the plastic deformation ring 500 is directly fixed to one of the one end surface of the control body 3 or the front end surface of the carbon body 2, the attachment area is narrow, and thus the rigidity of the coupling is somewhat increased. It can be a problem. However, as shown in FIGS. 4 to 10, an annular coupling groove 600 recessed inwardly is formed in one of one end surface of the steering body 3 or the front end surface of the body 2, and the plastic Deformation ring 500 may be installed so that one side is fixed to the coupling groove 600, the other side is plastic deformation by absorbing the launch impact of the projectile (1). In other words, since the one side of the plastic deformation ring 500 is inserted through the coupling groove 600 and buried therein, the attachment area can be widened to further secure the rigidity of the coupling.

As shown in FIGS. 5 and 6, the plastic deformation ring 500 has to be plastically deformed by the impact of the launch vehicle 1, so that it is difficult for the plastic deformation ring 500 to be a brittle material that easily breaks the material or an elastic material with excellent restoring force. Therefore, the plastic-deformed ring 500 can be made of a metal or an alloy of a soft material which is plastic-deformed, and for example, steel, a copper alloy, an aluminum alloy, or the like can be used depending on the size of a launching impact. It is more preferable to use the above. The degree to which the plastic deformation ring 500 is plastic-deformed by the impact of the launch vehicle 1 should be designed differently according to the overall size of the projectile 1, but it is preferable that the plastic deformation ring 500 is approximately 0.03 mm to 0.2 mm It is suitable as plastic deformation amount.

On the other hand, it will vary depending on the metal or alloy material of the plastic deformation ring 500, but if the size of the projectile (1) is very large, even if the plastic deformation of the plastic deformation ring 500 is not properly due to the launch impact of the projectile (1). 9 and 10, as shown in FIGS. 9 and 10, the uneven surface 510 may be formed on the other side of the plastic deformation ring 500. Therefore, the plastic deformation ring 500 can be more easily plastically deformed by the impact force of the same force even at a small contact area through the protrusions and recesses 510 of the plastic deformation ring 500.

The plastic deformation of the plastically deformed ring 500 can largely absorb the impact of the launch vehicle 1 to reduce the impact transmitted to the bearing outer ring 300. However, 300 may be provided with an elastic force to further attenuate the transmitted impact. That is, as shown in FIGS. 7 and 8, the bearing 2 is fixedly coupled to the inner peripheral surface of the tip end portion of the body 2 and is positioned between the pair of bearing outer rings 300, And an annular resiliently deformable ring 700 made of an elastic material that provides an elastic force in contact with one side of the outer ring 300. In the case of the elastic deformation ring 700, it refers to a material or a spring which is easy to shrink and expand due to an external force such as elastic rubber or soft synthetic resin. Therefore, in a state where the resiliently deforming ring 700 is provided with the resilient force of the resilient deforming ring 700, the impact of the projectile 1, which is slightly transmitted to the bearing outer ring 300, can be completely absorbed and minimized.

The elastically deformable ring 700 may be installed on each of the pair of bearing outer rings 300. Since most of the impact of the projectile 1 is absorbed through the plastic deforming ring 500, The bearing outer ring 300 may be provided only on one of the bearing outer ring 300. When the resiliently deforming ring 700 comes into contact with one side surface of the bearing outer ring 300 and provides elastic force in the other direction of the bearing outer ring 300, the bearing outer ring 300 slides in the other direction, And the corresponding surface of the rolling member 300 may be deformed. The bearing stopper 800 may further include a bearing stopper 800 to prevent the bearing outer ring 300 from coming off due to the elastic force of the resiliently deforming ring 700. That is, the bearing stopper 800 is in contact with the other side of the bearing outer ring 300 in contact with the elastic deformation ring 700 in a ring shape as shown in Figures 7 and 8 to the bearing outer ring 300 It is fixedly coupled to the inner circumferential surface of the front end portion of the body 2 to prevent the separation.

On the other hand, the body 2 of the projectile 1, which is fired from a ground platform or a captive, is subjected to a spin motion together with firing. In the process of cruising toward the object to be struck, the spinning motion of the body 2 is continuously maintained. At this time, as shown in Figures 4 to 10 embedded in the outer peripheral surface of the rotating shaft 100 so as to be located between the pair of bearing inner ring 200, the coil stator 910 is wound around the coil is formed by a magnetic force And a rotor 920 made of a permanent magnet, which is embedded in the inner circumferential surface of the tip of the carbon body 2 so as to be located between the pair of bearing outer rings 300, and rotates together with the carbon body 2 to form a magnetic force. It may further include. As described above, the so-called generator using the stator 910 and the rotor 920, which produce electric power from the spinning motion of the body 2, can be easily implemented from the prior art, and thus a detailed description thereof will be omitted.

Each of the configurations of the decoupling bearing module for guided weapons according to the present invention has a cylindrical shape, a cylindrical shape, or a ring shape. This is because the trunk 2 or the manipulator 3 constituting the projectile 1 has a circular or annular shape in section Because.

Decoupling bearing module for guided weapons according to the present invention as described above, through the plastic deformation ring 500 is installed in the rotation interval (G) between the front end surface of the body 2 and the end surface of the steering body (3), First, when the storage, transportation and installation of the projectile (1) can be blocked at the source of foreign matter, etc. at the interval between the body (2) and the control (3), the second projectile (1) when the launch impact occurs While plastic deformation, most of the shot impact can be absorbed to minimize the risk of breakage. Third, the plastic deformation ring 500 is plastically deformed due to the firing impact, and a rotational interval G is generated, resulting in the body 2 and the control body 3. Separate spin movements between) can also be made smoothly.

The elastic deformation ring 700 that provides the elastic force to the bearing outer ring 300 is also absorbed by the bearing outer ring 300 through the bearing stopper 800 and the bearing outer ring 300 is displaced It is possible to provide the projecting body 1 capable of smoothly performing the separate spin motion between the body 2 and the pilot 3 and capable of conducting the induction control with high precision and reliability.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
