Yet another way to do bearings

(1/3) > >>

crueby:
Hi all,
We've all seen and discussed different ways to fabricate split bronze bearings on multiple threads. I just came across a layout that I had not seen before when looking at some old engine plans for a Navy engine. Rather than having two 180-degree halves for the bearing, then having to put in a pin or something to keep the bearing from spinning, they made the bearings less than 180 degrees and put lips on the openings they go into to keep them from spinning. Here is a snippet from the plans:

The upper left arrow shows the bearing 'halves', the other two arrows point at the openings they slip into. On this machine the bearings are kept from moving side to side by the larger diameter pieces on the shaft turning in the bearings.

Just thought I'd throw this one out there to show yet another way to do it!

That's an interesting variation on the theme. Thanks for posting it.

Could the Engine Frames be for an Inclined Paddle Wheel engine?

Complex!!  :hammerbash:.......would the Side Butt Caps [and there mating Lower Caps], be initially machined to  7 5/8" bore, then the 4 7/16" radial bore be created/machinned in a Vertcal Slotting machine that had an effective stroke of 10" +? :facepalm:

I cannot see any other method to manufacture the radiused profile + the lower interface profiles....or am I missing something?  :Doh:

These caps are on the uprights holding a ship windlass that hauls up the anchor, so they inclined it to brace against the weight. The way the plan sheet is labeled, these are castings with machined faces where needed. Hard to say how they machined it, all sorts of specialized machines probably.

the recesses for the bearings would be a walk in the park for a Butler or Elliot 32" shaper with a rotary tool indexer.  :cheers:
