Aquadrive Catalogue 2020

6 CV SHAFT THE AQUADRIVE SYSTEM The drive shaft of variable length includes two true plunging Constant Velocity joints that work independently at any angle, this eliminates the need for accurate engine alignment, either during initial installation or subsequent use. The rolling action of the balls within the CV-joints absorb all axial and radial loads, permitting the use of very soft engine mounts as well as reducing wear in connected bearings. A range of pre-machined gearbox coupling kits allows problem free coupling to almost every marine gearbox transmission. Our CV shafts, as a standalone ele- ment, do provide a perfect and maintenance free solution for coupling of waterjets, IPS drives etc. to the remote engine side. Beside the above mentioned homokinetic advantages, the ball joints absorb vibrations through the driveshafts. THRUST BEARING Aquadrive thrust bearing assemblies with rubber mounts attach to a cross brace in the hull. Robust bearings transfer the thrust directly to the hull and not the engine. In addition, the propeller shaft is much better supported, leading to smoother running and less wear on the stern seal. ENGINE MOUNTS Aquadrive’s proven engine mounts are softer than almost any other and should be used to take full advantage of the system. These mounts are steel hooded to prevent diesel damage and fully captive so that the engine cannot leave its frame even if the vessel is turned over.
