Drive coupling specialists Vulkan, based in Germany, is supplying both fixed and flexible drive couplings to Brazil’s home-built burgeoning offshore energy sector, and interestingly is also involved in a project to develop a nuclear-powered submarine propulsion system for the Brazil Navy. The diesel engine beats to the sound of a pulsating drum in its cycle giving rise to shaft vibration. Secondly, slight misalignments, in connected drive shafts also need to be smoothed out, and to achieve this, flexible couplings incorporate rubber-like polymer subrstances in their design – elastomers.Vulcan explains that compound research in its R&D facility with highly specialized vulcanization technology has led to the development of an elastomer with considerably higher power density  – the 'Acotec' compound. This new compound distinguishes itself from other conventionally used materials not only through its enhanced tensile and tear strength and increased ultimate ... [More]
