The coupling needed to accommodate a large amount of radial and axial misalignment due to the sway of the resilient mounted engine as the tug moves through the current and waves.
After a careful review of the challenging application requirements, Stromag engineers recommended the use of a Stromag Vector 20 coupling, which has a maximum torque rating of 14,603 ft.lbs. (19,800 Nm) and a high misalignment capacity.
The highly flexible Vector coupling uses Stromag’s GE elastic element concept with high tensile strength fabric embedded into the rubber. This design has years of proven performance in diverse applications worldwide. The coupling provides zero backlash, flywheel-to-shaft and shaft-to-shaft connections. The radial arrangement of the coupling’s flexible element within a compact design allows for installation and removal without the need to move the drive units.
