In 2016, VULKAN Couplings, the innovative provider of system solutions for maritime drive systems, introduced the new VULKARDAN F. These highly flexible couplings are optimally suited for use in freestanding and flexibly mounted main and auxiliary drives, and power generation.
Even though it was introduced over five years ago, the VULKARDAN F is torsionally softer, shorter, and considerably lighter than any other comparable product. This contributes to optimal operation of the drive systems and a clear improvement in the acoustic properties of the ship's drive system, and ensures a high level of comfort.
Different Designs, Same Reliability
The VKF will be available in different designs: for flywheels and shafts, for main drives and for flexibly mounted generators. There will also be a version for auxiliary drives onboard ships and a version with a torque limiter device for a safe return home (after an overload-related damage). Available in four optimized rubber stiffness classes and in a silicone version that optimally tune the torsional vibration behavior of different drive systems, the VULKARDAN F can achieve a minimal vibratory torque load.
Since the introduction of sizes F54 and F57, VULKAN Couplings has since further developed the VULKARDAN F line and added three other sizes : the F50, F 60 and F62 up to 24" with SAE flywheel connections. Combined, these products cover a torque range between 4 kNm and 25 kNm and SAE connections between 14” and 24.”
Outstanding acoustic properties
The VULKARDAN F couplings are characterized by outstanding acoustic properties and they have received the required type approval from all major classification companies. The extremely high demand for this coupling and the satisfied customers also substantiates the practical suitability of the VULKARDAN F.
“Selecting the right coupling configuration is of utmost importance when you want to optimize structure-borne noise transmitted by the gearbox,” said Eric de Leeuw van Weenen, Director of Business Development at VULKAN USA. “Effective isolation is often a challenge due to natural frequencies in the transmission system and using the wrong coupling may cause excessive structure-borne noise.”
As an example, a noise reduction of more than 10 dB(A) was achieved in a yacht’s main saloon by replacing the original 3-row (competitor’s) coupling with a customized 2-row VULKARDAN F coupling.
Compact and short-build design for smallest possible space requirements and easy handling, the VULKARDAN F is available in four rubber qualities, enabling a perfect torsional tuning of the drive train.
