No more vibrations at the propeller shaft
The Sigmadrive joint considerably reduces the vibrations at the propeller shaft, improving the comfort on board and the life of the transmission components.
It is also possible to install the Sigmadrive coupling as an angular corrector in case there are small misalignments (within 3°) between the motor and the propeller shaft line.
How to install Sigmadrive
Installation of these products is very simple: simply remove the old flange/shackle that locks the axis and replace it with SigmaDrive. The axis locking method is the same as the old flange, and there is no need to change the length of the axis or the position of the motor. In terms of operation, SigmaDrive, when receiving thrust from the propeller shaft, acts as a pivot between the motor and the shaft, mechanically compensating for motor movement (vibration) and keeping the propeller shaft aligned with the bushings and seal. Sigmadrive also compensates for axis movements resulting from propeller turbulence.
