Boone B.V., a technical solutions provider and Stromag recently completed modification of a TRI Coupling that was needed on a trailing suction hopper dredge (TSHD) in the Netherlands.
Due to age and operating conditions, the existing competitor coupling’s rubber elements began to crack. Installed between the vessel’s main engine and generator, the flexible coupling provides torsional vibration dampening.
According to the Altra Motion release, Stromag’s engineering team worked closely with the Boone team to design the custom TRI coupling using standard elements to ensure that future spare part availability would not be a problem.
Altra added that torsional vibration calculations were also completed to confirm the coupling’s application suitability.
Ultimately, the modified TRI 125 coupling with a nominal torque rating of 98,740 Nm (72,826 ft.lbs.) was chosen by the customer over a competitor coupling due to the TRI’s superior technical suitability and fast delivery.
Highly flexible TRI rubber couplings are designed to be mounted directly to piston engine flywheels. Their high axial and radial misalignment capacity makes these couplings an ideal choice for resiliently mounted drives.
