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 HY
The Vetus vibration damper model HY is extremely suitable for application with marine diesel engines, by virtue of a low vertical stiffness, combined with high stiffness in the longitudinal direction. This sturdy vibration damper is suitable for engines in the power range between 30 and 125 kW, whether or not provided with a thrust bearing.
These flexible engine mountings are suitable for marine diesel engines in the power range between 30 kW and 125 kW (40hp - 170hp)
