Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and in particular to a disassembly method based on a large coupling. Background Technology

[0002] A coupling, also known as a shaft coupling, is a mechanical component used to securely connect the driving and driven shafts in different mechanisms, enabling them to rotate together and transmit motion and torque. It is sometimes also used to connect shafts to other parts (such as gears and pulleys). It is usually composed of two halves, each connected by a key or tight fit to one end of the shaft, and then joined together in some way. Couplings can also compensate for misalignment (including axial, radial, angular, or combined misalignment) between the two shafts caused by manufacturing or installation inaccuracies, deformation during operation, or thermal expansion; and can also mitigate shocks and absorb vibrations.

[0003] A coupling typically consists of two bushings, each connected to a corresponding drive shaft. Each bushing has an outer disc, which is coaxial with and integral with the bushing. The outer disc has several mounting holes. The two bushings are connected to their respective drive shafts, with the two outer discs touching and their mounting holes communicating. Mounting bolts are then passed through the corresponding mounting holes and secured with mounting nuts, thus achieving the linkage of the two drive shafts.

[0004] When using this disassembly device, the coupling bushing is first fixed, and then the mounting nut and mounting bolt are removed to release the fixed relationship between the two outer discs. Then, the drive shaft is pushed out by a jack. Since the bushing is installed on the drive shaft with an interference fit, it is inconvenient to push it out by this method, which increases the difficulty of disassembly. At the same time, the existing disassembly device cannot fix coupling bushings of different diameters, which reduces its working efficiency. Summary of the Invention

[0005] This invention discloses a disassembly method for large couplings, aiming to solve the problems in the prior art where the disassembly device is used. First, the coupling bushing is fixed, then the mounting nut and mounting bolt are removed to release the fixed relationship between the two outer discs. Then, the drive shaft is pushed out by a jack. Since the bushing is installed on the drive shaft with an interference fit, it is inconvenient to push it out in this way, increasing the difficulty of disassembly. At the same time, the existing disassembly device cannot fix the bushing of couplings with different diameters, reducing its working efficiency.

[0006] The present invention proposes a disassembly device based on a large coupling, including a tooling base. A disassembly assembly is provided on one side of the tooling base, and the disassembly assembly includes a tooling support plate one and a tooling support plate two. A mounting circular hole is opened on one side of the tooling support plate one, and a fixing circular frame is fixedly connected inside the mounting circular hole. A tensioning tooth plate is connected to one side of the fixing circular frame through a bearing, and an arc-shaped groove is opened at equal intervals on one side of the tensioning tooth plate.

[0007] In a preferred embodiment, a fixed seat is bolted to one side of the tooling support plate, and a general-purpose motor is fixedly connected to one side of the fixed seat. An adjusting gear is fixedly connected to the drive end of the general-purpose motor. The adjusting gear meshes with the tooth block end of the tensioning tooth plate. Slide grooves are provided at equal intervals on one side of the tooling support plate. A push slider is slidably connected inside each slide groove. A circular hole is provided on one side of each push slider. A limiting cylinder is connected inside each circular hole through a bearing. The limiting cylinder is located in the arc-shaped groove opened in the tensioning tooth plate.

[0008] In a preferred embodiment, the tooling support plate is provided with smooth holes at equal distances from one side of the fixed circular frame, and a clamping cylinder is slidably connected inside each smooth hole. One side of the clamping cylinder is fixedly connected to one side of the pushing slider. The same arc-shaped clamping plate is fixedly connected to one side of every two clamping cylinders. Two telescopic springs are fixedly connected to one side of each arc-shaped clamping plate. A power abutment plate is fixedly connected to one side of the two telescopic springs on the same arc-shaped clamping plate. The same coupling body is clamped on one side of multiple arc-shaped clamping plates.

[0009] In a preferred embodiment, a limiting sliding hole is provided on one side of the tooling support plate two, and a disassembly sliding column is slidably connected inside the limiting sliding hole. A reciprocating impact seat is bolted to one side of the disassembly sliding column, and an installation frame is bolted to one side of the tooling support plate two. Two return springs are fixedly connected to one side of the disassembly sliding column, and one side of the return spring is fixedly connected to one side of the installation frame.

[0010] In a preferred embodiment, two circular holes are provided on both sides of the mounting frame, and the two circular holes are connected to the same rotating shaft through bearings. A semi-circular gear is fixedly connected to one side of the rotating shaft, and a linkage rack is bolted to the side of the disassembly slide column. The linkage rack meshes with the tooth block end of the semi-circular gear. A drive motor is fixedly connected to one side of the mounting frame, and the drive end of the drive motor is connected to one side of the rotating shaft through a coupling.

[0011] With a disassembly assembly, when disassembling the coupling body, it is placed inside multiple arc-shaped clamping plates. Then, a universal motor is activated, driving an adjusting gear to rotate a tensioning gear plate. The arc-shaped grooves of the tensioning gear plate move, causing a limiting cylinder to move along a sliding block on a tooling support plate. This sliding block moves multiple arc-shaped clamping plates on one side of the clamping cylinder, simultaneously clamping and fixing the coupling body's bushing. When disassembling the drive shaft inside the bushing, a drive motor is activated, driving a semi-circular gear to rotate, causing the teeth of the semi-circular gear to mesh with the linkage gear. When the coupling is engaged, the linkage rack drives the reciprocating impact seat on the disassembly slide column to move to one side. At the same time, the return spring is compressed. When the tooth block end of the semi-circular gear separates from the linkage rack, the return spring rebounds quickly, causing the reciprocating impact seat to repeatedly impact the drive shaft inside the bushing. Simultaneously, the power abutment plate on the telescopic spring located on one side of the arc-shaped clamping plate buffers the impact force received by the bushing end of the coupling body, preventing displacement of the bushing part of the coupling body due to the reciprocating impact. By disassembling the assembly, it is easy to push the drive shaft out of the bushing of the coupling, reducing the difficulty of disassembly. At the same time, it can fix bushings of couplings with different diameters, improving its working efficiency.

[0012] In a preferred embodiment, a limit adjustment component is provided on one side of the tooling base, and the limit adjustment component includes a mounting rod. Slide grooves are equally spaced on one side of the tooling base, and the same adjustment slide is slidably connected inside the two slide grooves on the same side. Tooling support plate one and tooling support plate two are respectively bolted to one side of the adjustment slide.

[0013] In a preferred embodiment, one side of each of the two adjusting slides is bolted to a nut mounting tube, and both nut mounting tubes have screw holes inside. Both sides of the tooling base have three round holes, and the two round holes are connected to the same bidirectional screw through bearings.

[0014] In a preferred embodiment, an L-shaped support is fixedly connected to one side of the tooling base, and a lead screw motor is fixedly connected to one side of the L-shaped support. The drive end of the lead screw motor is connected to one side of a bidirectional screw via a coupling. The same limiting round rod is fixedly connected to one side of two opposing mounting rods. Two guide seats are slidably connected to the outside of the two limiting round rods. A compression spring is fixedly connected to one side of each guide seat at equal distances. The same fixing frame is fixedly connected to one side of multiple compression springs located on the same side. Circular holes four are opened at equal distances on both sides of the multiple fixing frames. Rotary rollers are connected to the inside of two opposing circular holes four via bearings. The outside of the rotating rollers abuts against the outside of the limiting round rods.

[0015] By incorporating a limit adjustment assembly, when disassembling the fixed coupling body, the lead screw motor is activated, driving a bidirectional screw to rotate. This causes the tooling support plates 1 and 2 on both sides to move in opposite directions, facilitating the disassembly assembly to disassemble coupling bodies of different lengths. During movement, tooling support plates 1 and 2 are limited by guide seats sliding outside the limiting rod, preventing deviation from the trajectory. Simultaneously, a compression spring compresses the rotating roller inside the fixed frame, causing it to abut against the outer wall of the limiting rod. The small contact area between the rotating roller and the limiting rod reduces friction. Furthermore, when the reciprocating impact seat impacts and disassembles the drive shaft inside the coupling body bushing, the lead screw motor is intermittently activated, causing tooling support plates 1 and 2 to gradually move in opposite directions, ensuring normal contact between the reciprocating impact seat and the drive shaft inside the coupling body bushing.

[0016] In a preferred embodiment, the tooling support plate 2 has two mounting ports on one side, and an electric drive rod is fixedly connected inside each of the two mounting ports. The drive ends of the two electric drive rods are fixedly connected to the same hollow circular frame. Air inlets are equidistantly provided on one side of the hollow circular frame. Two circular holes 5 are provided on one side of the tooling support plate 2. The same air inlet pipe is fixedly connected inside the two circular holes 5. The air outlet end of the air inlet pipe is connected to the inside of the hollow circular frame through a metal telescopic tube.

[0017] Equipped with an electric drive rod, an air inlet pipe, a metal telescopic tube, and a hollow circular frame, when disassembling the two outer discs of the coupling body, the electric drive rod is activated to move the hollow circular frame to the outside of the outer discs of the coupling body. Then, hot air is blown into the air inlet pipe and then heated through the air inlet in the hollow circular frame, thereby facilitating the flow of lubricating oil inside and making it easier to remove the mounting bolts of the two outer discs.

[0018] A method of using a disassembly device based on a large coupling, comprising the following steps:

[0019] Step 1: When disassembling the coupling body, place the coupling body inside multiple arc-shaped clamping plates. Then, start the general motor, which drives the adjusting gear to rotate the tensioning gear plate. As the tensioning gear plate moves, the arc-shaped groove drives the limiting cylinder to move on the tooling support plate by pushing the slider. By pushing the slider, the multiple arc-shaped clamping plates on one side of the clamping cylinder move simultaneously to clamp and fix the shaft sleeve of the coupling body.

[0020] Step 2: When disassembling the drive shaft inside the bushing, the drive motor is started, which drives the semi-circular gear to rotate. When the tooth block end of the semi-circular gear meshes with the linkage rack, the linkage rack drives the reciprocating impact seat on the disassembly slide column to move to one side. At the same time, the return spring is compressed. When the tooth block end of the semi-circular gear separates from the linkage rack, the return spring rebounds quickly, so that the reciprocating impact seat repeatedly impacts the drive shaft inside the bushing.

[0021] Step 3: At the same time as the impact, the dynamic abutment plate on the telescopic spring located on one side of the arc-shaped clamping plate buffers the impact force received by the coupling body bushing end, preventing the reciprocating impact from causing displacement of the coupling body bushing part.

[0022] As can be seen from the above, the disassembly device based on a large coupling provided by the present invention has the beneficial effects of facilitating the removal of the transmission shaft from the coupling sleeve, reducing the difficulty of disassembly, and fixing coupling sleeves of different diameters, thereby improving their working efficiency.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] The disassembly device for large couplings disclosed in this invention is mainly used when the coupling bushing is first fixed, and then the mounting nut and mounting bolt are removed to release the fixed relationship between the two outer discs. Then, the drive shaft is pushed out by a jack. Since the bushing is installed on the drive shaft with an interference fit, it is inconvenient to push it out by this method, which increases the difficulty of disassembly. At the same time, the existing disassembly device cannot fix the bushing of couplings with different diameters, which reduces its working efficiency.

[0035] Reference Figures 1-7 A disassembly device based on a large coupling includes a tooling base 1. A disassembly component 3 is provided on one side of the tooling base 1. The disassembly component 3 includes a tooling support plate 1 301 and a tooling support plate 2 313. A mounting circular hole is opened on one side of the tooling support plate 1 301. A fixing circular frame 303 is fixedly connected inside the mounting circular hole. A tensioning toothed plate 305 is connected to one side of the fixing circular frame 303 through a bearing. Arc-shaped slots are opened at equal intervals on one side of the tensioning toothed plate 305.

[0036] Reference Figures 1-7A fixed seat 306 is bolted to one side of the tooling support plate 301, and a general motor 307 is fixedly connected to one side of the fixed seat 306. An adjusting gear 308 is fixedly connected to the drive end of the general motor 307. The adjusting gear 308 meshes with the tooth block end of the tensioning tooth plate 305. Slide grooves are provided at equal intervals on one side of the tooling support plate 301. A push slider 302 is slidably connected inside each slide groove. A circular hole is provided on one side of each push slider 302. A limiting cylinder 309 is connected inside each circular hole through a bearing. The limiting cylinder 309 is located in the arc-shaped groove opened in the tensioning tooth plate 305.

[0037] Reference Figures 1-7 The tooling support plate 301 and the fixed circular frame 303 are provided with smooth holes at equal distances on one side, and each smooth hole is slidably connected to a clamping cylinder 304. One side of the clamping cylinder 304 is fixedly connected to one side of the pushing slider 302. The same arc-shaped clamping plate 310 is fixedly connected to one side of every two clamping cylinders 304. Two telescopic springs 311 are fixedly connected to one side of each arc-shaped clamping plate 310. The two telescopic springs 311 on the same arc-shaped clamping plate 310 are fixedly connected to one side of a power abutment plate 312. The same coupling body 2 is clamped on one side of multiple arc-shaped clamping plates 310.

[0038] Reference Figures 1-7 One side of the tooling support plate 313 has a limiting sliding hole, and a disassembly slide column 314 is slidably connected inside the limiting sliding hole. One side of the disassembly slide column 314 is connected to a reciprocating impact seat 315 by bolts. One side of the tooling support plate 313 is connected to a mounting frame 316 by bolts. Two return springs 320 are fixedly connected to one side of the disassembly slide column 314. One side of the return spring 320 is fixedly connected to one side of the mounting frame 316.

[0039] Reference Figures 1-7 The mounting frame 316 has two round holes on both sides, and the two round holes are connected to the same rotating shaft 318 through bearings. A semi-circular gear 319 is fixedly connected to one side of the rotating shaft 318. A linkage rack 317 is bolted to one side of the disassembly slide column 314. The linkage rack 317 meshes with the tooth block end of the semi-circular gear 319. A drive motor 321 is fixedly connected to one side of the mounting frame 316, and the drive end of the drive motor 321 is connected to one side of the rotating shaft 318 through a coupling.

[0040] In specific application scenarios, when disassembling the coupling body 2, it is placed inside multiple arc-shaped clamping plates 310. Then, by starting the general-purpose motor 307, the motor drives the adjusting gear 308, causing the tensioning gear plate 305 to rotate. The arc-shaped groove of the tensioning gear plate 305 moves, causing the limiting cylinder 309 to push the slider 302 onto the tooling support plate 301. This pushes the slider 302, causing the multiple arc-shaped clamping plates 310 on one side of the clamping cylinder 304 to move simultaneously, clamping and fixing the shaft sleeve of the coupling body 2. Then, when disassembling the drive shaft inside the shaft sleeve, the drive motor 321 is started. 321 drives the semi-circular gear 319 to rotate, so that when the tooth block end of the semi-circular gear 319 meshes with the linkage rod 317, the linkage rod 317 drives the reciprocating impact seat 315 on the disassembly slide column 314 to move to one side. At the same time, the return spring 320 is compressed. When the tooth block end of the semi-circular gear 319 separates from the linkage rod 317, the return spring 320 rebounds quickly, so that the reciprocating impact seat 315 reciprocates to impact the transmission shaft inside the bushing. At the same time, the power abutment plate 312 on the telescopic spring 311 located on one side of the arc-shaped clamping plate 310 buffers the impact force received by the bushing end of the coupling body 2, so as to prevent the reciprocating impact from causing displacement of the bushing part of the coupling body 2.

[0041] Reference Figure 1 , Figure 8 and Figure 9 The tooling base 1 is provided with a limit adjustment component 4 on one side, and the limit adjustment component 4 includes a mounting support rod 405. The tooling base 1 is provided with sliding grooves at equal intervals on one side. The same adjustment slide 401 is slidably connected inside the two sliding grooves on the same side. The tooling support plate 1 301 and the tooling support plate 2 313 are respectively connected to one side of the adjustment slide 401 by bolts.

[0042] Reference Figure 1 , Figure 8 and Figure 9 Both adjusting slides 401 have nut mounting tubes 402 bolted to one side, and both nut mounting tubes 402 have screw holes inside. Both sides of the tooling base 1 have three round holes, and the two round holes are connected to the same bidirectional screw 403 through bearings.

[0043] Reference Figure 1 , Figure 8 and Figure 9An L-shaped support 411 is fixedly connected to one side of the tooling base 1, and a lead screw motor 404 is fixedly connected to one side of the L-shaped support 411. The drive end of the lead screw motor 404 is connected to one side of the bidirectional screw 403 via a coupling. The same limiting round rod 406 is fixedly connected to one side of the two opposite mounting rods 405. Two guide seats 407 are slidably connected to the outside of the two limiting round rods 406. A compression spring 408 is fixedly connected to one side of each guide seat 407 at equal distances. The same fixing frame 409 is fixedly connected to one side of the multiple compression springs 408 located on the same side. Circular holes 4 are opened at equal distances on both sides of the multiple fixing frames 409. Rotary rollers 410 are connected to the inside of the two opposite circular holes 4 via bearings. The outside of the rotating rollers 410 abuts against the outside of the limiting round rods 406.

[0044] In specific application scenarios, when disassembling the fixed coupling body 2, the lead screw motor 404 is activated, driving the bidirectional screw 403 to rotate. This causes the tooling support plates 301 and 313 on both sides to move in opposite directions, facilitating the disassembly assembly 3 to disassemble coupling bodies 2 of different lengths. During the movement of the tooling support plates 301 and 313, the guide seat 407 slides outside the limiting rod 406 to limit their movement, preventing deviation from the trajectory. Simultaneously, the compression... Spring 408 presses the rotating roller 410 inside the fixed frame 409, causing the rotating roller 410 to abut against the outer wall of the limiting round rod 406. The contact area between the rotating roller 410 and the limiting round rod 406 is small, thereby reducing friction on the limiting round rod 406. At the same time, when the reciprocating impact seat 315 impacts and disassembles the transmission shaft inside the bushing of the coupling body 2, the intermittent starting of the lead screw motor 404 causes the tooling support plate 1 301 and tooling support plate 2 313 to move gradually in opposite directions, thereby ensuring normal contact between the reciprocating impact seat 315 and the transmission shaft inside the bushing of the coupling body 2.

[0045] Reference Figure 6 The tooling support plate 2 313 has two mounting ports on one side, and electric drive rods 5 are fixedly connected inside the two mounting ports. The driving ends of the two electric drive rods 5 are fixedly connected to the same hollow circular frame 8. Air inlets are opened at equal intervals on one side of the hollow circular frame 8. The tooling support plate 2 313 has two circular holes 5 on one side, and the same air inlet pipe 6 is fixedly connected inside the two circular holes 5. The air outlet of the air inlet pipe 6 is connected to the inside of the hollow circular frame 8 through a metal telescopic pipe 7.

[0046] In specific application scenarios, when disassembling the two outer discs of the coupling body 2, the electric drive rod 5 is activated to move the hollow circular frame 8 to the outside of the outer discs of the coupling body 2. Then, hot air is blown into the air inlet pipe 6 and heated through the air inlet of the hollow circular frame 8, thereby facilitating the flow of lubricating oil inside and making it easier to remove the mounting bolts of the two outer discs.

[0047] A method of using a disassembly device based on a large coupling, comprising the following steps:

[0048] Step 1: When disassembling the coupling body 2, place the coupling body 2 inside multiple arc-shaped clamping plates 310. Then, start the general motor 307, which drives the adjusting gear 308 to rotate the tensioning gear plate 305. As the tensioning gear plate 305 moves, the arc-shaped groove drives the limiting cylinder 309 to move on the tooling support plate 301 by pushing the slider 302. By pushing the slider 302, the multiple arc-shaped clamping plates 310 on one side of the clamping cylinder 304 move simultaneously to clamp and fix the bushing of the coupling body 2.

[0049] Step 2: When disassembling the drive shaft inside the bushing, the drive motor 321 is started, which drives the semi-circular gear 319 to rotate. When the tooth block end of the semi-circular gear 319 meshes with the linkage rack 317, the linkage rack 317 drives the reciprocating impact seat 315 on the disassembly slide 314 to move to one side. At the same time, the return spring 320 is compressed. When the tooth block end of the semi-circular gear 319 separates from the linkage rack 317, the return spring 320 rebounds quickly, so that the reciprocating impact seat 315 repeatedly impacts the drive shaft inside the bushing.

[0050] Step 3: At the same time as the impact, the dynamic abutment plate 312 on the telescopic spring 311 located on one side of the arc-shaped clamping plate 310 buffers the impact force received by the shaft sleeve end of the coupling body 2, so as to avoid the reciprocating impact causing displacement of the shaft sleeve part of the coupling body 2.

[0051] Working principle: When disassembling the coupling body 2, the coupling body 2 is placed inside multiple arc-shaped clamping plates 310. Then, by starting the general-purpose motor 307, the general-purpose motor 307 drives the adjusting gear 308 to rotate the tensioning gear plate 305. As the arc-shaped groove of the tensioning gear plate 305 moves, it drives the limiting cylinder 309 to push the slider 302 to move on the tooling support plate 301. By pushing the slider 302, the multiple arc-shaped clamping plates 310 on one side of the clamping cylinder 304 move simultaneously to clamp and fix the bushing of the coupling body 2. Then, the lead screw motor 404 is started, which drives the bidirectional screw 403 to rotate, so that the tooling support plates on both sides move. Support plate 301 and tooling support plate 313 move in opposite directions, facilitating the disassembly assembly 3 to disassemble coupling bodies 2 of different lengths. During movement, tooling support plate 301 and tooling support plate 313 are limited by guide seat 407 sliding outside the limiting rod 406 to prevent deviation from the trajectory. Simultaneously, compression spring 408 compresses the rotating roller 410 inside the fixed frame 409, causing the rotating roller 410 to abut against the outer wall of the limiting rod 406. The small contact area between the rotating roller 410 and the limiting rod 406 reduces friction on the limiting rod 406. Then, when disassembling the drive shaft inside the bushing, the drive motor 321 is started. The drive motor 321 drives the semi-circular gear 319 to rotate, causing the tooth block end of the semi-circular gear 319 to mesh with the linkage rack 317. At this time, the linkage rack 317 drives the reciprocating impact seat 315 on the disassembly slide 314 to move to one side. At the same time, the return spring 320 is compressed. When the tooth block end of the semi-circular gear 319 separates from the linkage rack 317, the return spring 320 rebounds quickly, causing the reciprocating impact seat 315 to reciprocate and impact the transmission shaft inside the bushing. At the same time, the power abutment plate 312 on the telescopic spring 311 located on one side of the arc-shaped clamping plate 310 buffers the impact force received by the bushing end of the coupling body 2, preventing the reciprocating impact from damaging the bushing part of the coupling body 2. When displacement occurs, and the reciprocating impact seat 315 impacts and disassembles the transmission shaft inside the bushing of the coupling body 2, the intermittent starting screw motor 404 causes the tooling support plate 301 and tooling support plate 313 to move gradually towards each other, so that the reciprocating impact seat 315 and the transmission shaft inside the bushing of the coupling body 2 can make normal contact. When disassembling the two outer discs of the coupling body 2, the electric drive rod 5 is started to move the hollow circular frame 8 to the outside of the outer discs of the coupling body 2, and then hot air is blown into the air inlet pipe 6, and then the outer discs of the coupling body 2 are heated through the air inlet of the hollow circular frame 8, so as to facilitate the flow of lubricating oil inside and facilitate the disassembly of the mounting bolts of the two outer discs.

The disassembly method includes the following steps: Step 1: When disassembling the coupling body (2), the coupling body (2) is placed inside multiple arc-shaped clamping plates (310). Then, by starting the general motor (307), the general motor (307) drives the adjusting gear (308) to rotate the tensioning gear plate (305). As a result, the arc groove of the tensioning gear plate (305) moves, it drives the limiting cylinder (309) to move on the tooling support plate (301) by pushing the slider (302). By pushing the slider (302), the multiple arc-shaped clamping plates (310) on one side of the clamping cylinder (304) move simultaneously to clamp and fix the bushing of the coupling body (2). Step 2: When disassembling the drive shaft inside the bushing, the drive motor (321) is started, and the drive motor (321) drives the semi-circular gear (319) to rotate, so that the tooth block end of the semi-circular gear (319) meshes with the linkage rack (317). At this time, the linkage rack (317) drives the reciprocating impact seat (315) on the disassembly slide (314) to move to one side. At this time, the return spring (320) is squeezed. When the tooth block end of the semi-circular gear (319) separates from the linkage rack (317), the return spring (320) rebounds quickly, so that the reciprocating impact seat (315) reciprocates to impact the drive shaft inside the bushing. Step 3: At the same time as the impact, the dynamic abutment plate (312) on the telescopic spring (311) located on one side of the arc-shaped clamping plate (310) buffers the impact force on the bushing end of the coupling body (2) to avoid the reciprocating impact causing displacement of the bushing part of the coupling body (2).
