RE: unknown shape

"specify" means describe ? tapped, splined shaft ?

maybe if you showed us the assembly we'd better undertand the function ?

if the thread is for a standard rod-end, then i wouldn't include it in the description.

another day in paradise, or is paradise one day closer ?

RE: unknown shape

(OP)
Yes, I am asking about spline shape.
This shape is not included in DIN ISO 14...

RE: unknown shape

I would guess that is a spline compliant with another standard (US or British or industry-specific?). Could be proprietary. Who knows???

RE: unknown shape

Can't you find the drawing?

RE: unknown shape

(OP)
Yes I need to copy this part and I do not have a drawing.

RE: unknown shape

Do a reverse engineering.

RE: unknown shape

with out some dimeinsions, it loooks like a 6T spline DIN9611, that is either imcomplete in machining or has reliefed roots.
a tractor 540rpm PTO drive?

RE: unknown shape

Who cares what you call it? 8<)

If you are actually legal to copy it, measure it.
Drawing the shape.
Figure out the material.
Tell the shop to make one "machined shaft" per dwg.

RE: unknown shape

It looks like an external fillet root involute spline based on an 18T blank with every third groove eliminated, with an end portion of the spline cut down to a reduced OD, and the full length of the single teeth cut down to the same reduced height.

RE: unknown shape

Search around for "Ball Screw Spline" or "Ball Spline".

RE: unknown shape

(if you're looking for a one-word adjective that sort of describes the cross-section, closest I can think of is "fluted" ;>)
