Flexible Coupling

This new flexible coupling from VETUS combines the best features of the well-known UNIFLEX and BULLFLEX models at a lower price. The Combiflex coupling has been designed to ensure optimal damping of torsional vibrations, created by cycle irregularities especially at low revs. The flexible rubber element ensures low-noise and vibration-free transmission, without backlash between the marine engine and the propeller shaft. The Combiflex coupling is secured against shearing off, both axially and radially, thus ensuring safe transmission under all circumstances. The Combiflex coupling also provides excellent alignment of the propeller shaft. Perfect alignment of engine and propeller shaft can be a rather time consuming affair, but the Combiflex comes to the aid of the installation engineer. Even with a misalignment of 2 degrees, the shaft will remain perfectly centred onto the gearbox flange. The parallel clamping hub ensures easy installation and probably even more importantly, easy dismantling of the shaftassembly. Compared with a tapered clamping hub costly machining of the shaft, tapering and keyway-cutting are no longer required. Just cut the shaft to length, free of burrs, degrease and install. The Combiflex has a 4” flange to fit most common gearbox models. For the most popular Volvo, Yanmar and Kanzaki gearboxes, special adapter flanges are available.
