Threaded flange affixing
Threaded flange affixing
(OP)
I have a question regarding affixing a threaded flange to a shaft.
The flange is the end element of a hydraulic cylinder transfering the axial force. The flange and shaft have a threaded connection.
My question is related to the method fixing the flange in position on the thread. Currently the idea is to use a pin as illustrated in the very crude sketch accompanying the post. (If it´s unclear I can make a more precise sketch but I have nothing better than paint on hand at the moment)
What worries me is that I have never seen an example of such a connection, and I´m doubtfull a pin can be used to secure a threaded connection.
The connection is mainly loaded axially with very little tangential stress, and must be easy to dismantle. The axial forces are approximately 100 tons. I have tried searching the forum and internet in general bu I am apparently asking the wrong question. I would be grateful on any advice given.

By the way I am a chemical engineer so I might be way off on this.

I can't make much of your sketch.
How about just a jam nut?
RE: Threaded flange affixing
I was also thinking of using a locking nut, it seems a logical solution.
Along that line is there a way to quantify the safety provided by the locking nut.
But just for future reference does anyone know if it is even possible to use something like a safety pin for securing a threaded connection.

It can be done, but:
It's hard to do.
It's ugly.
It's a custom match, and if it ever does get taken apart it won't line up again.
