JJP thanks for the response, I was thinking to follow this line of thinking. I plan on using this method, and ensuring the interference fit is sufficient.
Dan T,
The current design has a 0.002" interference fit so the clamping load can be transferred. So it does mimic the design you...
The current design is machined from a casting that is manufactured internally.
I think this thread has deviated to far from the intended target.
I'm trying to understand the calculations or assumptions needed to achieve confidence in creating a design based on this one, in the future.
Thanks...
This is an existing design that I am looking to understand and optimize for casting.
There are many of these couplings utilized by existing equipment at my company without any recorded failures after many years of use.
JJP your impression of the coupling is spot on, and I was under the same...
Good afternoon,
I am working on a rigid coupling that connects a gearbox to a driven shaft.
The shaft being coupled is a 10.125" Dia shaft (4140 @ 200-240 Brinell )seeing a 100,000 ft lbs of torque.
The shaft is keyed using a pair of 3.5 x 2.5" rectangular keys made from key steel @ 180...
