All Vetus engine mouting absorb the propeller thrust.
The torque of an engine is one of the deciding factors for determinations of the load applied to the engine mounts. When more powerful engines are installed, it is important to use the following formula to define the load per support in kg (4 supporting points).
(engine weight in kg / number of supports) + (kW x 487 x reduction of gearbox / engine rpm x centre to centre spacing in meters of longitudinal engine bearers) = max. load per support in kg
Type LMX
These flexible engine mountings are suitable for marine diesel engines in the power range between 70 kW and 350 kW (95hp - 480hp)
The Vetus flexible engine mounting type LMX has been designed with particular regard to the power to weight ratio of modern diesel engines, which is of ever growing importance. In other words: the weight of an engine, in comparison to its thrust, has become lower and lower. For these engine types, the Vetus flexible engine mounting type LMX possesses the following ideal characteristics:
- The ample vertical compression guarantees optimum damping of vibrations, even at idling.
- The horizontal fore and aft stiffness is very high, which allows the acceptance of considerable thrust.
- The cushioning of vibrations in horizontal direction athwartships is of equal excellence.
