Steering Gears, RMS Titanic
Steering Gears, RMS Titanic
(OP)
Interesting gear profile on these gears, apparently part of the mechanism used to drive the steering system of the Olympic-Class liners such as the RMS Titanic.
I'm not sure what the profile would be called. Double Herringbone perhaps?
This reference refers to the gears as 'Wilson-Pirrie' type.
"The steering gears for the Titanic were built by the machine shops at Harland & Wolff and were of the Wilson-Pirrie Type and were situated on C Deck under the after end of the Poop Deck."

I'd rather like to have smbdy have a look, smbdy specializing in the details of open gear engineering of that time, lest not to fall to a digital mockup

I have tried opening that link on a PC from IE, Chrome & Firefox and all I see is the opportunity to leave a review.
Are you using a mobile device?
In Chrome, this is all I'm seeing -

I hope it isn't a regional limitation; I'm in the U.S. There must be some consideration about international copyrights, though the page indicates it is freely distributable. It is over 1200 scanned pages or I would download and attach it here.

Sorry the link didn't work for you. I checked it before submitting the post and it worked OK for me. Like 3DDave I still run Win 7 Pro on my Dell workstation and use the current Firefox browser. Definitely worth a read to see how these types of gears were machined 100 years ago.
Here a link to another scanned version (from University of California library) of the same document: https://books.google.com/books?id=BMY7AQAAMAAJ&...

It was very illuminative about how to machine herringbone gears with an end mill, and also of how to construct a machine to do so.
Then it went on to hundreds of pages on all sorts of machinery and related subjects like laying out factories and hiring people and on and on.
Wow.

The most interesting part of these old steam-driven steering gears was the control valve that operated the steam cylinders. It would take an electrical signal from the pilot house and direct steam to the cylinders until the new rudder position was achieved. Then it would cut off the steam. It was entirely automatic. It had an internal worm gear and some other parts, and it was just a small part compared to the rest of the gear. Less than the size of a 1/4 HP induction motor. Truly an ingenious mechanism. I believe you can see them on the museum ships in Toledo, Ohio, the SS Willis B. Boyer and the SS Col. James M. Schoonmaker.
Modern steering gears are generally hydraulic. I have seen them with a Rapson Slide.
