Ultraflex 4-T71FC Fast Connect Steering Helm, Single Cable.
Ultraflex mechanical steering helms T71FC and T73NRFC, as well as their dual cable versions use Planetary Gear Design.
A Planetary Gear design has three satalite gears that rotate on their axis and at the same time rotate around the central helm axis.This allows for equal distribution of engine torque over three points of the central gear, dividing and balancing the system loads.
The benefits of the special design are increased system longevity, increase efficiency and less engine feedback compared to single pinion gear helms.
