Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to an anti-vibration coupling. Background Art

[0002] In many industrial fields, especially in situations involving large-scale machinery and important infrastructure, such as electricity, petroleum, chemical industry, transportation, etc., anti-vibration couplings are crucial components. They are not only used to transmit power and torque, but also can protect machinery and equipment from damage when ground vibration, vibration or impact occurs.

[0003] In traditional couplings, rigid connectors made of metal materials are usually used to connect two shafts. Although such couplings can effectively transmit force under normal circumstances, when encountering external vibration or impact, the rigid connection will cause vibration and impact to be transmitted to the entire mechanical system, which may cause damage or failure of the equipment, or even endanger personnel safety. However, the existing coupling structure still has the problems of poor stability after connection, lack of vibration resistance, and easy influence of external factors on the coupling.

[0004] Therefore, it is very necessary to invent a vibration-resistant coupling. Utility Model Content

[0008] The connection gasket adopts a group of annular rubber sheets, and the cross section of the connection gasket is consistent with the gap between the first coupling unit and the second coupling unit. After the installation is completed, the connection gasket is melted by high temperature heating to form a liquid that flows into the gap between the first coupling unit and the second coupling unit, which has the following functions: ① Buffering and vibration reduction: The connection gasket is made of annular rubber sheets and has good elasticity and vibration absorption performance.

[0022] The anti-vibration coupling is a device used to transmit rotational force and torque. It is designed to reduce the impact of ground vibration, vibration and shock on the mechanical system and improve the stability and reliability of the system. The working principle of the anti-vibration coupling will be introduced in detail below.

[0023] 1. Connection and force transmission: The first shaft body 1 and the second shaft body 2 are fixedly connected through the first coupling unit 3 and the second coupling unit 4.

[0024] 2. Relieve vibration and impact: One of the key components of the anti-vibration coupling is the connecting gasket 7, which is made of an annular rubber sheet. During operation, if the mechanical system is subjected to impact forces caused by external vibration or ground vibration, the connecting gasket 7 can absorb and alleviate these forces, thereby reducing the impact on the coupling and mechanical equipment.

[0025] 3. Support and stability: The first coupling unit 3 includes a support base 31, a mounting hole 32, a support arm 33 and a support base 34. These components together constitute a support structure, which helps to maintain the position and direction of the first shaft 1, reduce vibration and deviation during operation, and improve the stability and reliability of the system.

[0026] 4. Sealing and protection: The connection gasket 7 can not only relieve vibration and impact, but also play a sealing role to prevent external dust, impurities or liquids from entering the interior of the coupling and protect the internal parts from contamination and corrosion.

[0027] 5. Elastic compensation: The elastic characteristics of the connecting gasket 7 can compensate for axial, radial or angular deviations caused by temperature changes, mechanical loads or manufacturing errors, ensuring that the coupling can operate normally under different working conditions.

[0028] In summary, anti-vibration couplings can effectively reduce the impact of ground vibration, vibration and shock on mechanical systems through functions such as connection, vibration relief, support stability, sealing protection and elastic compensation, improve the stability and reliability of the system and extend the service life of the equipment.
