Rod Coupler

Rod Coupler

Rod Coupler

(OP)
I'd like to couple a 14mm solid steel shaft, to a 10mm x 1.5pitch
threaded rod.  If possibly I'd like to avoid modifying the
shafts in any way (threading the smooth one, drilling holes,
 ect).  Also, I would like the coupler to be removable.  

For the smooth shaft I was thinking of either screw-down
clamping sleeve or a simple sleeve with set screws.  For the
threaded rod I'd prefer if the couple is just threaded to
match and I can screw it in.

Is there anything like this available?

RE: Rod Coupler

Seems unlikely that there would be a sufficient market for a part like that to entice anyone to produce it for commercial distribution.

I think you're looking at a custom piece.

RE: Rod Coupler

xbulen,

If the shafts are to be coupled with anti-backlask , then try the following

If they are a straight mechanical coupling then the part will be bespoke.

I would contact Ruland. They make threaded shaft collars, also clamp-type rigid couplings. Although they do not show the exact item you are looking for in their catalog, I am confident they can easily adapt a stock item to your needs.

Is this a rotating joint?  Reciprocating?  Structural?

(OP)
It is a lever.  The force will be applied approx. 5" away from this joint (with the center of rotation approx. 2" in the other direction).  It  will be a few pounds of force, so it will have to be fairly sturdy.

I think more surface contact will be necessary than that of the collar-type couplings posted.

I would only need a few of these parts so a custom tooling seems a bit excessive, but I may have to fabricate something by hand if I cannot find anything suitable.
