A flexible coupling provides a flexible connection between the shaft and gearbox. This will reduce noise and vibration on board and is damping torsional vibrations.Blokflex couplings
Blokflex flexible couplings are manufactured according to our high quality standards. Loads can be transferred from different directions (both radially and axially). The flexible couplings are capable to transmit the propeller thrust to the gearbox. The construction of the coupling is fail-safe and ensures a long service life.
In case of the smaller coupling sizes (type 115-4 and 150-4), the aluminum housing is machined fit to the gearbox flange. The standard version comes with a straight bore and keyway. Larger types (160-6 and bigger) are using a separate steel adapter flange (spacer). This adapter is available for e.g. ZF/ Hurth/Velvet, PRM and Paragon gearboxes. Standard type 160-6 and bigger couplings come with a taper bore (1:10) and keyway.
Blokflex couplings can also be supplied with a self-centering clamp kit, instead of the standard keyed bore (an extra price is applicable).
