Flexible Marine Gearbox Couplings For Marine Engine Mounts

 

A flexible marine gearbox coupling is a device that fits between the output flange of the gearbox and the boat's propeller shaft. Its primary function is to reduce noise and vibration. Different types of marine coupling are available, and the choice depends on the horsepower of the engine and the gearbox, the application, and the available space. Some also reduce torque.

Poly Flex's VF coupling provides vibration control and high thrust load resistance. It is available for working loads ranging from 35kg to 2000kg, and it is available in a variety of base configurations and core shore hardness. It is best suited for high-speed diesel engines with SAE flywheels of 14 to 21 and torque up to 18.0 kNm.

These flexible marine gearbox couplings are made of special engineering polymer alloys that are extremely resistant to petrol, diesel, and salt-water. They are plated with SA5 Cobalt Zinc for maximum corrosion resistance and durability. They are ideal for commercial and pleasure boats. A range of sizes is available, ranging from three studs to 460mm in diameter.

A flexible marine gearbox coupling offers a number of benefits, including a low weight and easy installation. They also feature electrical isolation and reduce electrolysis. Typically, they are non-conductive, but can be supplied with a silver-impregnated rubber element that fits into the center of the coupling. The coupling can also be supplied with a female or male gearbox flange spigot.
