[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0017] The utility model coupling, such as Figure 1As shown, it includes a coupling body 1, which is provided with a connecting hole. The coupling body 1 includes a first half coupling 2, a second half coupling 3 and a noise reduction component 4. The first half coupling 2 and the second half coupling 3 are both made of high-strength alloy steel, which can withstand greater torque and load, and reduce the risk of deformation or breakage under high-load working conditions. The first half coupling 2 and the second half coupling 3 have the same structure except for the connecting hole. The first half coupling 2 and the second half coupling 3 can engage with each other. The first half coupling 2 and the second half coupling 3 are both detachably connected to the noise reduction component 4. The noise reduction component 4 includes a first noise reduction ring 5, a second noise reduction ring 6 and a noise reduction sleeve 7. The first noise reduction ring 5 and the second noise reduction ring 6 have the same structure.
[0018] like Figure 1 As shown, when in use, first insert the first half coupling 2 and the second half coupling 3 from both ends of the noise reduction sleeve 7 for clamping, and then install the first noise reduction ring 5 and the second noise reduction ring 6. The first noise reduction ring 5 is provided with a first protrusion 8, and the first protrusion 8 is provided with a plurality of first protrusions 8. The plurality of first protrusions 8 are distributed in a circular array on the outer side of the first noise reduction ring 5. The noise reduction sleeve 7 is provided with a second protrusion 9, and the second protrusion 9 is provided with a plurality of second protrusions 9. The plurality of second protrusions 9 are distributed in a circular array on the inner wall of the noise reduction sleeve 7. The second protrusion 9 can engage with the first protrusion 8, and the thickness of the first protrusion 8 is consistent with that of the second protrusion 9. Therefore, the first noise reduction ring 5 and the second noise reduction ring 6 can be inserted into the noise reduction sleeve 7. The noise reduction sleeve 7 is made of silicone rubber. Silicone rubber can effectively absorb and buffer the vibration and impact generated during the operation of the coupling, thereby reducing the generation and spread of noise. In addition, the temperature of the coupling is generally high, while silicone rubber can maintain stable performance within a wide temperature range and adapt to different working environment temperatures. At the same time, silicone rubber has good sealing properties, which can prevent dust, moisture and other impurities from entering the interior of the coupling, protecting the normal operation of the coupling, and reducing the noise caused by friction due to impurities.
[0019] like Figure 1 、 Figure 2 、 Figure 3As shown, an annular protrusion 10 is provided on one side of the first noise reduction ring 5, and a convex thread 11 is provided on the outer side of the annular protrusion 10. An annular groove 12 is provided on one side of the first half coupling 2, and a concave thread 13 is provided on the inner wall of the annular groove 12. The annular protrusion 10 is threadedly connected to the annular groove 12, and a shock-absorbing gasket 14 is provided between the convex thread 11 and the first noise reduction ring 5. Anti-skid protrusions 15 distributed in a circumferential array are provided at both ends of the noise reduction sleeve 7. When the first noise reduction ring 5 and the second noise reduction ring 6 are inserted into the two ends of the noise reduction sleeve 7, the first noise reduction ring 5 can be easily screwed into the first half coupling 2 with the help of the anti-skid protrusions 15. The second noise reduction ring 6 is screwed into the second half coupling 3, and due to the presence of the shock-absorbing gasket 14, the stability of the threaded connection between the two is improved. The tightening direction of the first noise reduction ring 5 and the second noise reduction ring 6 are both clockwise, and the noise reduction sleeve 7 is made of silicone rubber, which also has excellent elasticity. As the first noise reduction ring 5 and the second noise reduction ring 6 are tightened, the silicone rubber can be tightly wrapped around the surface of the coupling body 1, and because the first protrusion 8 is engaged with the second protrusion 9, the noise reduction sleeve 7 cannot recover by itself, and is always tightly wrapped around the outer surface of the coupling body 1, thereby improving its shock absorption and sound insulation effects.
[0020] Working principle: First, put the first noise reduction ring 5 and the second noise reduction ring 6 on the shafts of the machines to be connected on both sides, and then insert the shafts of the machines to be connected on both sides into the first half coupling 2 and the second half coupling 3 respectively, and then insert the first half coupling 2 and the second half coupling 3 into the noise reduction sleeve 7 and engage them, and then clamp the first protrusion 8 on the first noise reduction ring 5 and the second noise reduction ring 6 with the second protrusion 9 on the noise reduction sleeve 7, and then tighten the first noise reduction ring 5 and the second noise reduction ring 6 respectively through the anti-slip protrusion 15. The installation process has a simple structure and obvious effect.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
