3D heli-coil with cutouts

[Nifty280]

I require some advice / suggestions please as I need to draw a 3D heli-coil with cutouts. This is for a mixing auger where will be using ribbon flight with an integral leg to the centre pipe. I have no problems with the heli-coil just the cut out sections!

It would help if you could post an image or two and even better if you could attach a copy of the drawing to your next post. Without seeing the drawing we would be guessing.

Looks like you would sweep the correct profile along a helix and then mirror it?

 

I notice there are a handful of different designs so once again if we could get some further information in the way of an image or a drawing it would be helpful.

This is my "rough cut" as I've got some tweaking left to do but at least it is a start.

My variation on a theme Opus 1.

The magenta helix is inside the blue helix.

Oops...I think one of the support posts is out of place.

 

My advice/suggestions would be to not do what I did.

[ReMark]

What happened to Nifty? Did he lose interest?

I would not do cut outs i would simply offset it equal distance from the middle post that way it roll equally balanced inner and outter.

Just like the one remark posted.

 

In the shop it will be easy to make for the workers and like the one on the site you posted rings are cut out all the same sizes.

Voila the best and cheapest way to do it.

Thanks for the responses. There are many different variations of ribbon flight, I will see if I can post a picture to help clarify.

Shows profile of the ribbon flight before it is pressed / pulled.

What data can you provide regarding the helix?

 

The one you have pictured is quite different than most I have seen.

...I have no problems with the heli-coil just the cut out sections!

 

And yet, you still haven't attached your *.dwg file here.

 

Trim helical surface.

Thicken.

Done.

 

[ReMark]

Well that was easy. Next!

 

Wait. Can you demonstrate how it would be done in AutoCAD too?

Attach your dwg file here. (of swept helical surface)

 

When I think heli-coil this is what I think of http://www.helicoil.in/

used a lot of those in my previous work-life.

Really JD? That one is just too easy. I meant using the profile the OP posted the image of and the one you did in Inventor. I know you like a challenge.

[ReMark]

My first (rough) attempt using AutoCAD.

Before anyone starts throwing bricks I've yet to work out some of the kinks.

In other words...I know there is something wrong with it. Consider it a work-in-progress.

Top view. Looks kind of like a steering wheel.

 

Twist it up baby! Twist it up baby. Twist and shout!

 

OK. That's enough fun and frivolity for one morning. Time for an early lunch.

[ROBP]

But a world away from the one on the Falcon site you did indeed trough us off quite a bit.

 

hehe

[ReMark]

I'm not sure who you are talking about.

[Nifty280]

JD that's exactly what I'm after and I was actually going to draw this in Solid Works. Could you please humour me and explain that process with a bit more detail.
