unknown shape 1

[cervantes]

Hi all,

does anyone knows which norm describes this kind of shape? I have completely no idead how to specify this on the drawing

thanks in advance

 

[rb1957]

"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 ?

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

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

 

[europipe]

Can't you find the drawing?

 

[cervantes]

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

Do a reverse engineering.

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?

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.

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.

 

[FACS]

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

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