Mock-up Rack and Pinion steering components
Schedule
of correct (designed) dimensions
Relative wide recess for draglink movement :-(
Notes to myself
So far, I am not satisfied with the above R&P solutions.
That's why I've ultimately
chosen for a transmission steering system.
Some notes and sketches for
myself.
It turns out that the proposed position of the gearbox is too far aft
with the
consequence that the torque tube is too high for the aft cabin bed
where it is
intended to go underneath the bed bottom.
The solution is to move forward the whole rudder 96 mm.
This means the lower step
in the stern will change in width from 374 to 278 mm.
Resulting in a 210 mm.
extension of the reduction gearbox shaft.
Below the final design and ordered Jefa parts.
The reduction gearbox is housed in
its own watertight compartment
and separated from "outside" by a sealed roller
bearing.
The still missing pedestal is on my design board and will be built
in composite by myself.
Now this looks more like what I was looking,
a nice compact setup with minimal
couplings
and an integrated autopilot drive unit.
Case closed.
