The world wide market leader for dual stage couplings between diesel engines and flanged marine gear. It has a torsionally very soft roller coupling for the first stage to avoid gear clatter at low speeds as well as a stiffer, robust and failsafe 2. stage for higher speeds. Silicon versions for high temperatures are available.
Extremely low torsional stiffness at low speeds (idling), therefore the resonance falls far below idling speed and torsional vibrations and gear noise are avoided, and a very low idling speed becomes possible.
The stiffer, robust, well proven jaw coupling transmits the torque at higher speeds.
Simple, compact, reliable and economical design - no bonded rubber, no rubber in shear, only rubber in compression i.e. ideal working conditions. The rubber is heat resistant and the coupling has internal ventilation for good heat dissipation.
Failsafe
Suitable for blind assembly in flanged housings, input shaft of the gear can be splined or tapered.
Well matches sizes for SAE flywheels and all types of gears.
Ship propulsion main drives, between diesel engine and flange mounted gear, or between diesel engine and independently mounted gear, if both are rigidly mounted and well aligned.
auxiliary drives for high idling speeds, e.g. with clutches, fire extinguishing pumps etc.
