Engine shaft coupling for ships
VULKARDAN L : 0.4 - 40.0 KNM VULKAN Kupplungs

The VULASTIK-L coupling is a torsionally flexible rubber coupling, that compensates axial, angular and, to a certain degree, radial displacement of the connected machines. Four rubber qualities and silicone are available in order to tune the coupling to the various system requirements. VULASTIK-L couplings are available with one elastic element in standard design or with two elements acting in parallel in Dual design. The main parts of the VULASTIK-L coupling are hub and flanged casing, between these, the disc-shaped element is arranged. This disc element is connected by vulcanization at its inner radius, the outer radius is connected to the flanged casing by a "plug-in" toothing. This toothing provides the axial "plug-in" feature and compensation of shaft displacements. The permissible angular coupling displacement is 0.5°. The VULASTIK-L elements are made from heat-resistant rubber, the admissible ambient temperatures range from -45°C to +90°C. Alternative elements in silicone are available (ambient temperatures range from -45°C to +120°C). With respect to a long lifetime, however, consideration should be given to sufficiently large ventilation cross sections. This is very important when considering bellhousing.
