Fillet radius on turned shaft
Fillet radius on turned shaft
(OP)
I have been asked to review a tension rod design for a safety catcher on a press. Bascially the catcher is a rod that goes up and down through a cylindrycal braking mechanism. The vendor is looking to attach the fixed end of the rod using a collar connection. The rod will have to be turned down to receive the collar. He is asking me to specify the radius at the edges of the turned portion. I beleive that this is to reduce stress concentrations at these locations. Does anyone have any idea of how to arrive at the appropriate radius?
Thanks,
Jim

Sometimes you can undercut/relieve the shoulder to get a bigger radius or use a compound radius for lower SCF's.
