Compact drive line couplings for high performance and low inertia

摘要

An innovative design of shaft clamp is delivering key benefits in a range of power transmission applications, not least in the highly challenging marine environment. We look at their use on the latest super yachts, and how they are delivering a new paradigm in torque transmission capability, reliability and ease of maintenance. Marine power transmission systems make stringent demands on shafts and clamping components. Not only must they deliver high torque capacity, but they must also offer high levels of reliability combined with ease of maintenance. Marine power transmission systems can require frequent disassembly for maintenance, so quick mounting of dismounting is an essential feature. Then there is the challenging marine environment and the fact that there is often very little space in which to work. As yachts increase in size, outboard propulsion systems quickly become inappropriate, whilst on the very largest yachts and highest powered craft exotic propulsion systems such as water jets are becoming fashionable. But for yachts between 40 and 100 feet in length, from luxury yachts right up to the so-called super yachts, by far the most common propulsion arrangement where speeds above 40 knots are not required is the in-board drive with conventional submerged propellers.
