As a widely used mechanical transmission device, the serpentine spring coupling has unique characteristics mainly reflected in the following aspects:
1. Structural design and functional characteristicsStructural composition: The serpentine spring coupling is composed of an elastic cylindrical elastic element consisting of two half coupling sleeves and an outer ring, which is connected to a parallel outer ring through two semicircular keys, and the two semicircular keys are fixed together through the hole of the inner ring. This structure makes the coupling have high flexibility and reliability when transmitting torque.Diverse functions: The serpentine spring coupling not only has the function of compensating the relative offset of the two shafts of the flexible coupling, but also has different degrees of buffering function of the elastic coupling and overload retention function of the safety coupling. It can effectively reduce vibration and impact and improve the stability and life of the transmission system.2. Performance characteristicsGood shock absorption: The serpentine spring coupling can effectively absorb and disperse the vibration and impact in the transmission process through its internal elastic element-serpentine spring, thereby reducing the noise and vibration level of the equipment and improving the smooth operation of the equipment.High transmission efficiency: Due to the compact structure and high matching accuracy of the serpentine spring coupling, it can maintain a high transmission efficiency and reduce energy loss when transmitting torque.Strong load-bearing capacity: The serpentine spring coupling has a high load-bearing capacity and can transmit a large torque. It is suitable for various medium and small power transmission systems.Allowing large angular displacement and axis offset: This feature makes the serpentine spring coupling more flexible and convenient during installation and use, and can adapt to the axis offset and angular displacement under different working conditions.
3. Tooth design and stress analysisTooth design: The tooth shapes on the two half couplings of the serpentine spring coupling are generally linear and curved. Straight teeth are suitable for occasions where the torque changes little, while curved teeth are suitable for occasions where the torque changes greatly. Different tooth designs can meet different transmission requirements.Stress analysis: Under actual working conditions, the serpentine spring coupling will be subjected to various forces during operation, including torque, vibration and impact. Therefore, its stress analysis is an important part of the design process. Through reasonable stress analysis, it can be ensured that the coupling can still maintain stable performance and long service life when subjected to various loads.4. Use and maintenanceEasy installation: The installation of the serpentine spring coupling is relatively simple and quick, and can be completed without complex tools and equipment.Simple maintenance: Due to its compact structure and good sealing, maintenance during use is relatively simple and convenient. However, it should be noted that the operating status and wear of the coupling should be checked regularly during use, and damaged parts should be replaced in time to ensure its normal operation.
The unique characteristics of the serpentine spring coupling mainly come from its structural design and functional characteristics, performance characteristics, tooth design and stress analysis, and use and maintenance. These characteristics make the serpentine spring coupling have broad application prospects and important value in the field of mechanical transmission.
