Marine coupling is a key component that connects the main engine and the gear unit. They are designed to ensure the effective operation of the ship's power system. These couplings can not only transmit torque, but also play a role in buffering, reducing vibration and improving the dynamic performance of the shaft system in high-speed and heavy-load power transmission. Especially between the elastically mounted main engine and the rigidly arranged propeller-thrust bearing, the use of flexible couplings suitable for marine propulsion can compensate for possible shaft displacement and prevent the deformation of the ship's base from having an adverse effect on the gearbox through the propeller shaft. In addition, Marine gearbox couplings also have an overload safety protection function, which can reduce vibration and impact in the mechanical transmission system and protect the equipment from damage.
1. Marine coupling has high strength and reliability. Marine coupling needs to withstand the huge torque transmitted by the ship's power system. Marine coupling is generally made of high-strength metal materials and is made through precision forging to ensure that it can reliably transmit power without loosening, breaking, etc., and ensure the continuity and stability of the ship's power transmission.
2. Marine coupling has good centering and coaxiality. The ship's power system has high requirements for transmission accuracy. When connecting two transmission shafts, the couplings for marine propeller shafts must ensure good centering and coaxiality. Even when the ship is shaken and vibrated by external forces such as wind and waves, the two transmission shafts can be kept in a nearly coaxial state.
3. Marine coupling has corrosion resistance. Since ships operate in the marine environment for a long time, Modern marine shaft couplings face the threat of corrosion factors such as seawater and salt spray. The anti-corrosion coating on the surface of the coupling can form a protective film on the surface of the coupling to prevent seawater from contacting the metal matrix and play an anti-corrosion role.
4. Marine Shaft Couplings have buffering and shock absorption functions. The ship power system will generate vibration during operation, and marine coupling has buffering and shock absorption functions, which can effectively reduce the transmission of these vibrations in the shaft system.
Marine coupling is widely used in the field of navigation. In the scope of commercial ships, whether it is a large ship that transports containers, oil, ore and other goods, or various passenger ships, its power system cannot do without marine coupling to ensure stable power transmission between the main engine and the transmission shaft and propeller to achieve efficient navigation. On military vessels, from aircraft carriers to frigates and submarines, marine flexible shaft coupling plays a key role in the maneuverability and combat effectiveness of the vessels, ensuring accurate power transmission to perform various combat missions. In addition, it is equally important in small vessels such as fishing boats and yachts, allowing the vessels to drive smoothly on rivers, lakes and seas, turn flexibly, and safely sail on the waters.
