Marine forged couplings mainly include the following types: flange couplings, gear couplings, elastic pin couplings, star couplings, elastic sleeve pin couplings, and chain couplings, among others. Of course, I can further introduce the characteristics and applicable scenarios of these marine forged couplings.

1. Flange Coupling: Also known as a flange coupling, it connects two half couplings with flanges using bolts to achieve the connection of two shafts. This type of coupling has a simple structure, is easy to manufacture, and is low in cost, but requires moving the machine during assembly and disassembly, making it suitable for low-speed, high-rigidity drive shafts.
2. Gear Coupling: Composed of two inner gear rings and a middle sleeve, it transmits torque through the engagement of internal and external gears. It allows for certain axial, radial, and angular displacements between the two shafts and transmits a large torque, but is complex to manufacture and costly, making it suitable for situations where the distance between the two shafts is relatively far and high transmission accuracy is required.
3. Elastic Pin Coupling: Utilizes several non-metallic elastic materials to form pins, which are placed in the flange holes of the two half couplings, connecting the two half couplings through the pins. This type of coupling has a simple structure, is easy to manufacture, convenient for assembly and disassembly, and does not require lubrication, but the elastic elements have certain limitations on the magnitude of the transmitted torque, making it suitable for medium and small power drive shafts.
4. Plum Blossom Coupling: Composed of two half couplings with the same claw shape and elastic elements, it uses plum blossom-shaped elastic elements placed between the claws of the two half couplings to achieve their connection. It has advantages such as compensating for relative displacement between the two shafts, vibration reduction, buffering, small radial dimensions, simple structure, and no lubrication required, but the transmitted torque is limited, making it suitable for medium and small power drive shafts with low alignment precision requirements and small load variations.
