Description

Technical Field

[0001] The present application relates to the technical field of couplings, in particular to a clamp-type coupling. Background Art

[0002] Couplings are important connecting components in mechanical transmission systems, used to achieve power transmission between two shafts. Traditional couplings mainly include rigid couplings, elastic couplings and universal couplings. Rigid couplings have a simple structure and high transmission efficiency, but have high requirements for the alignment of the two shafts and are prone to vibration and impact; elastic couplings absorb vibration and impact through elastic elements and are suitable for occasions with poor alignment, but have limited load-bearing capacity; universal couplings can compensate for larger angular displacements, but have a complex structure and are relatively expensive.

[0003] However, the low centering accuracy of the existing clamp-type coupling may cause unstable relative motion between the two shafts, thereby generating vibration and noise, which will not only affect the smooth operation of the equipment, but may also interfere with the surrounding environment. Long-term vibration and unstable operation will accelerate the wear of the coupling and its related components, and may even cause damage, increase maintenance costs, and may also affect the overall life of the equipment. Low centering accuracy will lead to increased energy loss in the power transmission process, thereby reducing transmission efficiency, which will affect the overall performance and operating efficiency of the equipment. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a clamp-type coupling, which has the advantages of improving installation stability, etc., and solves the problem that the low centering accuracy of the existing clamp-type coupling may cause unstable relative movement between the two shafts, thereby generating vibration and noise, which not only affects the smooth operation of the equipment, but may also cause interference to the surrounding environment. Long-term vibration and unstable operation will accelerate the wear of the coupling and its related components, and may even cause damage, increase maintenance costs, and may also affect the overall life of the equipment. Low centering accuracy will lead to increased energy loss in the power transmission process, thereby reducing transmission efficiency, which will affect the overall performance and operating efficiency of the equipment.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a clamp-shell coupling, comprising an upper fixed sleeve and a lower fixed sleeve, wherein the upper fixed sleeve and the lower fixed sleeve are both fixedly connected to a plurality of anti-slip strips, and the upper and lower fixed sleeves are both fixedly connected to mounting plates on both sides of the outer walls, and the upper and lower fixed sleeves are both fixedly connected to a plurality of reinforcing plates arranged in a linear array on the outer walls, and the plurality of reinforcing plates are each provided with three through holes therethrough, and the plurality of through holes are each fixedly connected to an anti-torsion rod in a group of five, and the bottom end of the upper fixed sleeve is fixedly connected to a plurality of positioning pins arranged in a rectangular array, and the upper end of the lower fixed sleeve is provided with a plurality of positioning holes arranged in a rectangular array.

[0006] Through the above scheme, multiple anti-slip strips are fixedly connected to the inside of the upper fixed sleeve and the lower fixed sleeve, which can increase the friction between the connected shaft, prevent sliding during transmission, and reduce vibration during transmission, ensuring the stability and reliability of transmission. The outer wall of the coupling is provided with multiple reinforcing plates in a linear array. These reinforcing plates not only enhance the overall structural strength of the coupling, but also provide it with additional support and protection, enabling it to withstand greater torque and load. Anti-torsion bars are fixedly connected in the through holes opened through the inside of the reinforcing plates. These anti-torsion bars can effectively resist the transmission of torque and prevent the coupling from deformation or damage during force. The bottom end of the upper fixed sleeve is provided with multiple locating pins, and the upper end of the lower fixed sleeve is provided with locating holes matching the locating pins. This design enables the upper and lower fixed sleeves to be easily aligned and fixed, ensuring precise alignment between the two shafts. The device has the advantages of improving transmission stability, enhancing load-bearing capacity, simplifying the installation process and increasing service life.

[0007] Furthermore, a plurality of mounting holes arranged in a linear array are provided inside the four mounting plates, and anti-slip washers are fixedly connected to the inner walls of the plurality of mounting holes.

[0008] Through the above solution, the anti-slip washer on the inner wall of the mounting hole can increase the friction between the bolt or nut and the mounting plate, effectively preventing the bolt or nut from loosening during vibration or load changes, thereby ensuring a stable connection between the coupling and the mechanical equipment. The use of the anti-slip washer makes the fit between the mounting hole and the bolt or nut tighter, reduces the vibration and noise caused by the fit clearance, and improves the connection reliability between the coupling and the mechanical equipment.

[0009] Furthermore, a plurality of the mounting holes are slidably connected to the inside thereof with fixing bolts, and one end of the plurality of the fixing bolts passing through the mounting holes is threadedly connected to a nut.

[0010] Through the above solution, the fixed bolt design of the sliding connection makes the installation process more convenient. The bolt can be easily slid into the mounting hole and then fixed by the nut without the need for additional tools or complicated operating steps. The threaded connection between the nut and the bolt provides a strong fixing force, ensuring that the coupling can be firmly installed on the mechanical equipment. This connection method can also maintain stability and prevent loosening even in the event of vibration or load changes. When the coupling needs to be disassembled or replaced, it is only necessary to loosen the nut and pull out the bolt. This design simplifies the maintenance process and reduces maintenance costs.

[0011] Furthermore, a positioning groove is provided on the inner wall of the upper fixing sleeve.

[0012] Through the above solution, the design of the positioning groove enables the upper fixing sleeve to be more accurately aligned with the transmission component, and by matching the shape of the connecting shaft of the transmission component, it can better drive the transmission component.

[0013] Furthermore, the plurality of positioning pins are all slidably arranged inside the positioning hole.

[0014] Through the above solution, the sliding fit between the locating pin and the locating hole ensures the installation accuracy between the upper fixing sleeve and the lower fixing sleeve, reduces the vibration and noise caused by misalignment, and improves the stability and reliability of the transmission.

[0015] Furthermore, the upper ends of the plurality of positioning holes are all provided with chamfers.

[0016] Through the above solution, the presence of the chamfer makes it easier for the locating pin to align with the locating hole, thereby speeding up the installation speed. The chamfer design makes the locating pin smoother when inserted into the locating hole, simplifies the installation process, and reduces damage caused by improper installation.

[0017] Furthermore, the plurality of anti-slip strips are all made of rubber.

[0018] Through the above solution, the rubber material has natural elasticity, the rubber anti-slip strip can fit tightly to the surface of the connecting shaft, effectively preventing sliding during the transmission process, ensuring the stability and reliability of the transmission, the rubber material has good wear resistance, and can withstand long-term use and frequent friction without easy wear, which helps to extend the service life of the coupling, and the rubber material has certain shock-absorbing properties, which can absorb and disperse the vibration and impact generated during the transmission process, which helps to reduce the noise and vibration of mechanical equipment and improve the stability and reliability of the entire transmission system.

[0019] Furthermore, the upper fixing sleeve and the lower fixing sleeve are both made of carbon steel.

[0020] Through the above solution, the carbon steel material has excellent strength and hardness, and can withstand large mechanical stress and loads, so that the upper and lower fixed sleeves are not easily deformed or damaged when subjected to high torque, thereby ensuring the stability and reliability of the coupling. The carbon steel material has good wear resistance and can maintain surface flatness and precision during long-term use, reducing performance degradation and failure risks caused by wear, and extending the service life of the coupling.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The clamp-shell coupling has multiple anti-slip strips fixedly connected to the inside of the upper and lower fixed sleeves, which can increase the friction between the connected shafts, prevent sliding during transmission, reduce vibration during transmission, and ensure the stability and reliability of transmission. The outer wall of the coupling is provided with multiple reinforcing plates in a linear array. These reinforcing plates not only enhance the overall structural strength of the coupling, but also provide it with additional support and protection, enabling it to withstand greater torque and load. Anti-torsion bars are fixedly connected in the through holes opened through the inside of the reinforcing plates. These anti-torsion bars can effectively resist the transmission of torque and prevent the coupling from deformation or damage during force. The bottom end of the upper fixed sleeve is provided with multiple locating pins, and the upper end of the lower fixed sleeve is provided with locating holes matching the locating pins. This design enables the upper and lower fixed sleeves to be easily aligned and fixed, ensuring precise alignment between the two shafts.
