Technical Field

[0001] The invention relates to the technical field of turning gears, in particular to a coupling turning gear traction device. Background Art

[0002] In the industrial production process, it is usually necessary to perform cranking operations on rotating equipment in a stopped state, such as couplings, steam turbines, etc., to reduce the occurrence of rotor bending and deformation due to long-term shutdown of the equipment, or scaling of the rotating parts of the equipment, which causes the equipment to lock and be unable to start. This makes cranking operations a very important part of equipment maintenance work.

[0003] In the traditional method of turning the coupling, the equipment needs to be powered off and the protective cover removed for approval. After that, the workers continue to turn the coupling by manually pushing it to turn for a certain period of time. When maintaining a larger coupling, multiple workers are usually required to manually turn and maintain the coupling.

[0004] A turning gear is a special tool for installing, maintaining and repairing rotating equipment. It is widely used in scenarios involving coupling installation and shaft alignment. In the prior art, a Chinese patent with publication number CN113567150A proposes a new type of efficient shaft turning gear assembly and torque detection platform device and a method of use, which includes a shaft assembly support, the shaft assembly support is connected to a shaft rotation support, the shaft rotation support is connected to a shaft rotation traction, the shaft rotation traction is connected to a shaft assembly platform, an electrical control system is arranged on the shaft assembly platform, four groups of step assemblies with the same structure are connected to the shaft assembly platform, and the fixed axis is rotated by traction driving the shaft rotation support, so that the turning gear and torque detection can be achieved in a shorter time.

[0005] With regard to the above technical solution, the rotating equipment is prone to local deformation after long-term use or placement. The prior art usually adopts fixed-size assembly supports and shaft system rotation traction, which can easily cause assembly errors during turning, resulting in wear or assembly failure of the rotating equipment, thereby affecting the turning accuracy of the rotating equipment. Summary of the invention

[0006] Based on this, it is necessary to provide a coupling turning traction device to address the above-mentioned technical problems. When using this device, the coupling can be quickly clamped and the position can be fine-tuned, effectively bearing a larger load, improving the stability of the coupling rotation, maintaining the effective output of traction force, reducing assembly errors during turning, and reducing the risk of wear or assembly failure of the rotating equipment, thereby improving the turning accuracy of the rotating equipment.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A coupling turning tractor comprises a frame, a wall panel and a coupling, and a driving mechanism, a transmission mechanism, a traction mechanism and a fixing mechanism all arranged on the wall panel, wherein the wall panel is arranged on the frame, the fixing mechanism is used to install the coupling on the wall panel, the driving mechanism is used to drive the transmission mechanism to rotate, the transmission mechanism is used to drive the traction mechanism to rotate, and the traction mechanism is used to drive the coupling to rotate;

[0009] The fixing mechanism includes a clamp and an adjusting assembly, the clamp is rotatably set on the wall panel, the clamp is used to install the coupling on the wall panel, the adjusting assembly includes a first pin, a second pin and a tensioning screw, the first pin is set on the wall panel, the second pin is set on the clamp, one end of the tensioning screw is connected to the first pin, and the other end is connected to the second pin.

[0010] By adopting the above technical solution, when in use, the coupling is installed between the wall panel and the clamp, the tensioning screw is connected and installed on the first column pin and the second column pin, and it is adjusted so that the coupling can be clamped quickly and accurately, the driving mechanism starts to drive the transmission mechanism to operate, the transmission mechanism drives the traction mechanism to operate, and then the coupling is pulled to rotate, and the laser detector array detects the surface of the coupling; in this way, the coupling is quickly clamped and the position is fine-tuned through the clamp, wall panel and tensioning screw, the assembly error during the turning is reduced, the probability of serious wear of the equipment is reduced, the transmission mechanism and the traction mechanism are used for multi-stage transmission, the torque transmission capacity is improved, and a stable speed output is provided. During the startup phase, it can effectively withstand a large Load, improve the stability of the coupling rotation, when applied to turning operations with slight shaft misalignment, can reduce the vibration transmission caused by rigid connection, suitable for space-constrained scenes such as machine rooms, improve the scope of application and reliability, and thus improve the turning accuracy of rotating equipment; the installation tightness of the clamp is adjusted by the first column pin, the second column pin and the tensioning screw. When the coupling is locally deformed, expands due to heat, or produces axial displacement due to load changes, workers can compensate for the tightness of the belt in time by adjusting the tensioning screw to adjust the tension, thereby maintaining the effective output of traction, improving output efficiency, reducing the probability of belt slippage, and thereby reducing the risk of wear or assembly failure of rotating equipment, thereby improving the turning accuracy of rotating equipment.

[0011] As a preferred embodiment of the coupling turning device provided by the present invention, the fixing mechanism includes a rotating roller and a roller frame, the roller frame is arranged on the clamp, and the rotating roller is rotatably arranged on the roller frame.

[0012] By adopting the above technical scheme, the rotating roller installed on the clamp is rollingly connected with the coupling, and the sliding friction is converted into rolling friction, which is beneficial to reducing the degree of wear between the coupling and the clamp. When the coupling is locally deformed or slightly offset due to assembly error, the tangential force generated by rolling friction can reduce the probability of the rotating equipment getting stuck or slipping, and improve the turning accuracy of the rotating equipment. At the same time, the roller frame, as a distributed support structure, can evenly transfer the radial load of the coupling to each connection position of the clamp, reduce the probability of deformation of the clamp due to local stress concentration, and thus improve the turning accuracy of the rotating equipment.

[0013] As a preferred embodiment of the coupling turning device provided by the present invention, the fixing mechanism further includes a detection component, and the detection component includes a laser detector array, and the laser detector array is arranged on the clamp.

[0014] By adopting the above technical solution, the laser detector array detects the surface of the coupling, which is convenient for timely observation of the deformation of the equipment surface and rotation deviation data during the turning operation, so that workers can adjust the assembly status of the coupling in time, eliminate potential risks such as coupling wear and aging, improve the stability and reliability of equipment use, and thus improve the turning accuracy of the rotating equipment.

[0015] As a preferred embodiment of the coupling turning device provided by the present invention, the rotating roller is made of elastic material.

[0016] By adopting the above technical scheme, the rotating roller made of elastic material has a certain deformation ability. When there are foreign objects or burrs on the surface of the coupling, the elastic deformation can effectively alleviate the contact impact and reduce the wear of the equipment. It is convenient for workers to observe the deformation of the rotating roller and adjust the assembly state of the coupling in time to reduce the assembly deviation. At the same time, the rotating roller made of elastic material can absorb the high-frequency vibration existing in the turning process of the equipment to a certain extent, improve the stability of the coupling rotation, and thus improve the turning accuracy of the rotating equipment.

[0017] As a preferred embodiment of the coupling turning and traction device provided by the present invention, the laser detector array is arranged at one end of the hoop close to the rotating roller.

[0018] By adopting the above technical scheme, the laser detector array detects the surface of the rotating roller. When the laser detector array detects that the rotating roller is deformed, it means that the coupling has undergone local deformation or local stress concentration during the turning process, which is convenient for workers to adjust the assembly state of the coupling in time, reduce assembly deviations, and improve the rotation stability of the coupling. At the same time, the rotating roller made of elastic material can absorb the high-frequency vibrations existing in the turning process of the equipment to a certain extent, which is beneficial to reduce the measurement error of the laser detector array caused by mechanical vibration and reduce the scattering loss of the laser beam, thereby improving the turning accuracy of the rotating equipment.

[0019] As a preferred embodiment of the coupling turning device provided by the present invention, the detection component also includes a traction belt, and the rotating rollers and roller frames are provided in multiple and one-to-one correspondence, and the traction belt is sleeved on multiple rotating rollers.

[0020] By adopting the above technical scheme, when the coupling is turned, the traction belt is set on multiple rotating rollers to form a loop. When the coupling has local deformation or axial vibration, the traction belt can reduce torque fluctuations through the friction between the rotating rollers and the traction belt, thereby reducing the impact on the transmission efficiency. At the same time, when some rotating rollers are greatly deformed or a single set of roller frames fails, the traction belt allows the traction force to be distributed in a certain proportion among the multiple rotating rollers, which is conducive to the laser detector array to accurately detect the overall deformation of the rotating rollers, thereby effectively judging the overall deformation of the coupling, and then accurately judging the assembly state of the coupling, reducing the probability of misjudgment, reducing assembly errors, and thus improving the turning accuracy of the rotating equipment.

[0021] As a preferred embodiment of the coupling handwheel traction device provided by the present invention, the adjustment component also includes a hydraulic cylinder and a locking valve. The hydraulic cylinder is arranged on the wall panel, one end of the locking valve is connected to the output end of the hydraulic cylinder, and the other end is connected to the tensioning screw. The hydraulic cylinder is connected to the electrical signal of the laser detector array.

[0022] By adopting the above technical solution, when the coupling is turned, the laser detector array detects the surface of the rotating roller. When the laser detector array detects that the rotating roller is locally deformed, the laser detector array transmits a signal to the hydraulic cylinder, and the hydraulic cylinder is started to drive the locking valve to further tighten or loosen the tensioning screw. Through the setting of the hydraulic cylinder and the locking valve, the device can adjust the clamping force of the coupling with higher accuracy and more timely adjustment, and can perform dynamic adjustment according to the signal feedback from the laser detector array, thereby effectively reducing the labor intensity of workers, improving work efficiency, and improving the stability and reliability of equipment use, thereby improving the turning accuracy of the rotating equipment.

[0023] As a preferred embodiment of the coupling turning tractor provided by the present invention, the adjustment component also includes an airbag and an air pump. The airbag is arranged at one end of the wall panel close to the belt, and the output end of the air pump is connected to the airbag.

[0024] By adopting the above technical solution, when the equipment has shaft system deviation, stress concentration or equipment slippage during operation, the air pump inflates the airbag so that the airbag contacts the surface of the coupling to provide a certain degree of support for the coupling. After the airbag is inflated, a flexible contact surface is formed, which produces a certain deformation according to the surface contour of the coupling to adapt to the coupling surface under different local deformation conditions, thereby reducing the probability of belt slippage. At the same time, the air inside the airbag can effectively absorb high-frequency vibrations during the turning process, reducing the probability of vibration being transmitted to other equipment such as wall panels and causing resonance, thereby reducing the probability of wear or assembly failure of the rotating equipment, and thereby improving the turning accuracy of the rotating equipment.

[0025] As a preferred embodiment of the coupling disc puller provided by the present invention, the driving mechanism includes a driving device, a driving gear and a driving chain, the transmission mechanism includes a transmission gear and a transmission chain, the traction mechanism includes a leather roller and a belt, the driving device is arranged on the wall panel, the driving gear is rotatably arranged on the wall panel, the driving gear is transmission-connected to the output end of the driving device, the driving chain is sleeved on the driving gear, the driving gear is meshed with the driving chain for transmission, the driving gear is connected to the transmission gear, the transmission gear is rotationally arranged on the wall panel, the transmission chain is sleeved on the transmission gear, the transmission gear is meshed with the transmission chain for transmission, the transmission gear is connected to the leather roller, the leather roller is rotationally arranged on the wall panel, the belt is sleeved on the leather roller, the leather roller is in rolling contact with the coupling, and the leather roller is used to drive the coupling to rotate.

[0026] By adopting the above technical solution, when in use, the driving device is started, and the output end of the driving device drives the driving gear to rotate, the driving gear drives the transmission gear to rotate through the driving chain, the transmission gear drives the remaining transmission gears to rotate through the transmission chain, and then drives the leather roller to rotate. By using transmission gears, transmission chains, leather rollers and belts for multi-stage transmission, the torque transmission capacity is improved, stable speed output is provided, output efficiency is improved, and the probability of belt slippage is reduced.

[0027] As a preferred embodiment of the coupling turning device provided by the present invention, the belt is also provided with spiral groove patterns.

[0028] By adopting the above technical solution, the spiral groove patterns on the belt surface form a certain angle with the running direction of the coupling, which can effectively improve the friction coefficient of the belt surface and reduce the probability of belt slippage, thereby reducing the probability of large wear or assembly failure of the rotating equipment. At the same time, the spiral groove patterns can form a heat dissipation channel, thereby improving the heat dissipation efficiency of the coupling during operation and improving the stability and reliability of equipment use.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The coupling can be quickly clamped and fine-tuned in position through the clamp, wall plate and tensioning screw to reduce the assembly error during turning. The transmission mechanism and traction mechanism are used for multi-stage transmission to improve the torque transmission capacity and provide stable speed output. During the startup phase, it can effectively withstand large loads and improve the rotation stability of the coupling. When it is used in turning operations with slight shaft misalignment, it can reduce the vibration transmission caused by the rigid connection. When the coupling has local deformation or axial displacement, the tensioning screw is adjusted to compensate for the clamping tightness in time to maintain the effective output of traction force, reduce the probability of belt slippage, and thus reduce the risk of wear or assembly failure of the rotating equipment, and improve the turning accuracy of the rotating equipment.

[0031] 2. The rotating roller installed on the clamp is connected to the coupling in a rolling manner, converting the sliding friction into rolling friction, which is beneficial to reducing the wear between the coupling and the clamp. When the coupling is locally deformed or slightly offset due to assembly error, the tangential force generated by rolling friction can reduce the probability of the rotating equipment getting stuck or slipping, and improve the turning accuracy of the rotating equipment. At the same time, the roller frame, as a distributed support structure, can evenly transfer the radial load of the coupling to each connection position of the clamp, reducing the probability of deformation of the clamp due to local stress concentration, thereby improving the turning accuracy of the rotating equipment.

[0032] 3. The rotating roller made of elastic material has a certain deformation ability. When there are foreign objects or burrs on the surface of the coupling, the elastic deformation can effectively alleviate the contact impact and reduce the wear of the equipment. It is convenient for workers to observe the deformation of the rotating roller and adjust the assembly state of the coupling in time to reduce the assembly deviation. At the same time, the rotating roller made of elastic material can absorb the high-frequency vibration existing in the turning process of the equipment to a certain extent, improve the stability of the coupling rotation, and thus improve the turning accuracy of the rotating equipment.

[0033] 4. The laser detector array detects the surface of the rotating roller. When the laser detector array detects that the rotating roller is deformed, it means that the coupling has experienced local deformation or local stress concentration during the turning process. This allows workers to adjust the assembly state of the coupling in time, reduce assembly deviations, and improve the rotation stability of the coupling. At the same time, the rotating roller made of elastic material can absorb high-frequency vibrations in the turning process of the equipment to a certain extent, which is beneficial to reduce the measurement error of the laser detector array caused by mechanical vibration and reduce the scattering loss of the laser beam, thereby improving the turning accuracy of the rotating equipment.

[0034] 5. When the coupling is turned, the traction belt is set on multiple rotating rollers to form a loop. When the coupling has local deformation or axial vibration, the traction belt can reduce torque fluctuations through the friction between the rotating rollers and the traction belt, thereby reducing the impact on transmission efficiency. At the same time, when some rotating rollers are greatly deformed or a single set of roller frames fails, the traction belt allows the traction force to be distributed in a certain proportion among multiple rotating rollers, which is conducive to the laser detector array to accurately detect the overall deformation of the rotating rollers, thereby effectively judging the overall deformation of the coupling, and then accurately judging the assembly status of the coupling, reducing the probability of misjudgment, reducing assembly errors, and thus improving the turning accuracy of the rotating equipment.

[0048] In order to solve this technical problem, the present invention provides a coupling turning gear traction device, which is used in the turning gear operation of the rotating equipment.

[0049] Specifically, please refer to Figures 1 to 4 The coupling barring traction device specifically comprises: a frame 1, a wall panel 2 and a coupling 3, and a driving mechanism 4, a transmission mechanism 5, a traction mechanism 6 and a fixing mechanism 7 all arranged on the wall panel 2, the wall panel 2 is arranged on the frame 1, the fixing mechanism 7 is used to install the coupling 3 on the wall panel 2, the driving mechanism 4 is used to drive the transmission mechanism 5 to rotate, the transmission mechanism 5 is used to drive the traction mechanism 6 to rotate, and the traction mechanism 6 is used to drive the coupling 3 to rotate;

[0055] Example 1: Please refer to Figures 1 to 4 A coupling turning device comprises a frame 1, a wall panel 2, a coupling 3, a driving mechanism 4, a transmission mechanism 5, a traction mechanism 6 and a fixing mechanism 7.

The transmission gear 51 is connected to the leather roller 61 and is coaxially arranged.

The leather roller 61 and the belt 62 are used to drive the coupling 3 to rotate, and the belt 62 is also provided with a spiral groove pattern.

[0058] The fixing mechanism 7 includes a clamp 71, an adjusting component 72, a rotating roller 73, a roller frame 74 and a detection component 75. The adjusting component 72 includes a first pin 721, a second pin 722 and a tensioning screw 723. One end of the clamp 71 is rotatably connected to the wall panel 2. The clamp 71 is used to install the coupling 3 on the wall panel 2.

The roller frame 74 is rotatably connected to the clamp 71, and the rotating roller 73 is fixedly connected to the roller frame 74. The detection component 75 includes a laser detector array 751, and the laser detector array 751 is fixedly connected to the clamp 71.

[0059] The working principle of this embodiment is:

[0060] When in use, the coupling 3 is installed between the wall panel 2 and the clamp 71, the tensioning screw 723 is connected and installed on the first column pin 721 and the second column pin 722, and adjusted so that the coupling 3 can be clamped quickly and accurately, the driving device 41 is started, and the output end of the driving device 41 drives the driving gear 42 to rotate, and the driving gear 42 drives the transmission gear 51 to rotate through the driving chain 43, and the transmission gear 51 drives the remaining transmission gears 51 to rotate through the transmission chain 52, thereby driving the leather roller 61 to rotate, and the leather roller 61 drives the belt 62 to rotate, thereby driving the coupling 3 and the belt 62 to rotate frictionally, pulling the coupling 3 to rotate, and the laser detector array 751 detects the surface of the coupling 3.

[0061] With such arrangement, the coupling 3 is quickly clamped and finely adjusted in position through the clamping hoop 71, the wall panel 2 and the tensioning screw 723, thereby reducing the assembly error during the turning and the probability of serious wear of the equipment. By using the transmission gear 51, the transmission chain 52, the leather roller 61 and the belt 62 for multi-stage transmission, the torque transmission capacity is improved and a stable speed output is provided. In the startup phase, the elastic friction contact between the belt 62 and the coupling 3 can effectively withstand a large load and improve the rotation stability of the coupling 3. When applied to the turning operation with slight shaft misalignment, the vibration transmission caused by the rigid connection can be reduced. It is suitable for scenes with limited space such as machine rooms, and the scope of application and reliability are improved, thereby improving the turning accuracy of the rotating equipment.

[0062] The spiral grooves on the surface of the belt 62 form a certain angle with the running direction of the coupling 3, which can effectively increase the friction coefficient of the surface of the belt 62 and reduce the probability of the belt 62 slipping, thereby reducing the probability of large wear or assembly failure of the rotating equipment. At the same time, the spiral grooves can form a heat dissipation channel, thereby improving the heat dissipation efficiency of the coupling 3 during operation and improving the stability and reliability of the equipment.

[0063] The installation tightness of the clamp 71 is adjusted by the first column pin 721, the second column pin 722 and the tensioning screw 723. When the coupling 3 is partially deformed, expands due to heat, or has axial displacement due to load changes, the worker can adjust the tensioning screw 723 to compensate for the tightness of the belt 62 in time, thereby adjusting the tension, thereby maintaining the effective output of traction, improving the output efficiency, reducing the probability of the belt 62 slipping, and thus reducing the risk of wear or assembly failure of the rotating equipment, thereby improving the turning accuracy of the rotating equipment;

[0064] The rotating roller 73 installed on the hoop 71 is connected to the coupling 3 by rolling, and the sliding friction is converted into rolling friction, which is beneficial to reduce the wear between the coupling 3 and the hoop 71. When the coupling 3 is locally deformed or slightly offset due to assembly error, the tangential force generated by the rolling friction can reduce the probability of the rotating equipment getting stuck or slipping, and improve the turning accuracy of the rotating equipment. At the same time, the roller frame 74, as a distributed support structure, can evenly transfer the radial load of the coupling 3 to each connection position of the hoop 71, reduce the probability of deformation of the hoop 71 caused by local stress concentration, and thus improve the turning accuracy of the rotating equipment.

[0065] The surface of the coupling 3 is detected by the laser detector array 751, so that the deformation of the equipment surface and the rotation deviation and other data can be observed in time during the turning operation, so that the workers can adjust the assembly state of the coupling 3 in time, eliminate the potential risks such as the wear and aging of the coupling 3, improve the stability and reliability of the equipment, and further improve the turning accuracy of the rotating equipment.

[0066] Example 2: Please refer to Figures 1 to 4 , a coupling turning puller provided in Example 1 is further optimized. Specifically, the difference between it and Example 1 is that: the rotating roller 73 is made of elastic material, the laser detector array 751 is fixedly connected to one end of the clamp 71 close to the rotating roller 73, the laser detector array 751 is used to detect the surface of the rotating roller 73, the adjustment component 72 also includes a hydraulic cylinder 724 and a locking valve 725, the hydraulic cylinder 724 is fixedly connected to the wall panel 2 by bolts, one end of the locking valve 725 is connected to the output end of the hydraulic cylinder 724, and the other end is connected to the tensioning screw 723, and the hydraulic cylinder 724 is electrically connected to the laser detector array 751.

[0067] The working principle of this embodiment is:

[0068] When the coupling 3 is turned, the laser detector array 751 detects the surface of the rotating roller 73. When the laser detector array 751 detects that the rotating roller 73 is locally deformed, the laser detector array 751 transmits a signal to the hydraulic cylinder 724. The hydraulic cylinder 724 starts to drive the locking valve 725 to further tighten or loosen the tensioning screw 723.

[0069] The rotating roller 73 made of elastic materials such as polyurethane has a certain deformation ability. When there are foreign objects or burrs on the surface of the coupling 3, the elastic deformation can effectively alleviate the contact impact and reduce the wear of the equipment. At the same time, when the laser detector array 751 detects that the rotating roller 73 is deformed, it means that the coupling 3 has local deformation or local stress concentration during the turning process, which is convenient for workers to adjust the assembly state of the coupling 3 in time, reduce assembly deviation, and improve the rotation stability of the coupling 3. At the same time, the rotating roller 73 made of elastic material can absorb the high-frequency vibration existing in the turning process of the equipment to a certain extent, which is conducive to reducing the measurement error of the laser detector array 751 caused by mechanical vibration, and reducing the scattering loss of the laser beam, thereby improving the turning accuracy of the rotating equipment;

[0070] By setting the hydraulic cylinder 724 and the locking valve 725, the device can adjust the clamping force of the coupling 3 with higher accuracy and more timely, and can perform dynamic adjustment according to the signal feedback from the laser detector array 751, thereby effectively reducing the labor intensity of workers, improving work efficiency, improving the stability and reliability of equipment use, and thus improving the turning accuracy of the rotating equipment.

[0071] Example 3: Please refer to Figures 1 to 4, a coupling turning traction device provided in Example 2 is further optimized. Specifically, it differs from Example 2 in that: the detection component 75 also includes a traction belt 752, two rotating rollers 73 and roller frames 74 are each provided and correspond one to one, the traction belt 752 is sleeved on the two rotating rollers 73, the traction belt 752 is in frictional contact with the two rotating rollers 73, the traction belt 752 is in frictional contact with the coupling 3, the adjustment component 72 also includes an airbag 726 and an air pump 727, the airbag 726 is detachably connected to one end of the wall panel 2 close to the belt 62, and the output end of the air pump 727 is connected to the airbag 726 through a pipeline.

[0072] The working principle of this embodiment is:

[0073] When the coupling 3 is turned, the traction belt 752 is sleeved on the multiple rotating rollers 73 to form a loop. When the coupling 3 has local deformation or axial vibration, the traction belt 752 can reduce torque fluctuations through the friction between the rotating rollers 73 and the traction belt 752, thereby reducing the impact on the transmission efficiency. At the same time, when some rotating rollers 73 are greatly deformed or a single group of roller frames 74 fails, the traction belt 752 allows the traction force to be distributed in a certain proportion among the multiple rotating rollers 73, which is conducive to the laser detector array 751 to accurately detect the overall deformation of the rotating rollers 73, thereby effectively judging the overall deformation of the coupling 3, and then accurately judging the assembly state of the coupling 3, reducing the probability of misjudgment, reducing assembly errors, and thus improving the turning accuracy of the rotating equipment;

[0074] When the equipment experiences shaft system deviation, stress concentration or equipment slippage during operation, the air pump 727 inflates the airbag 726 so that the airbag 726 contacts the surface of the coupling 3, providing a certain degree of support for the coupling 3. After the airbag 726 is inflated, a flexible contact surface is formed, which is deformed to a certain extent according to the surface contour of the coupling 3 to adapt to the surface of the coupling 3 under different local deformation conditions, thereby reducing the probability of slippage of the belt 62. At the same time, the air inside the airbag 726 can effectively absorb high-frequency vibrations during the turning process, reducing the probability of vibration being transmitted to other equipment such as the wall panel 2 and causing resonance, thereby reducing the probability of wear or assembly failure of the rotating equipment, and thereby improving the turning accuracy of the rotating equipment.
