Chain
Chain
(OP)
Hi,
Does someone know how to draw a chain? I already have one link. I can copy that one, but the constraints between the two links aren't copied.
Plz?

RE: Chain
It will be a bit of work, but I can't think of a way around it.
RE: Chain
It will be indeed quite a work. luckely i only need one concentric constraint to connect two links.

RE: Chain
Yea, but it would be nice if i can insert my chain and just put it around the chainwheels. Thats why i need the constraints.
RE: Chain
Some time ago I tried to design a chain and put it around the chain wheel, but with no success. Try to find some videos in youtube about modeling chains. as I remember there are few, but made with solid works or inventor.
RE: Chain
If I did download a copy, not sure which of the 5 CDs of files it would be on. Maybe with my new 8GB USB memory device, I can consolidate and cleanup the CDs. In my spare time, of course!

RE: Chain
I searched youtube about modeling chain. I saw a video where they draw the path the chain must follow, divide it into equal pieces and put a link at each point of the path (something like follow path or something).
But i never saw the doing constraints.
Is there something like autoconstraint in NX? If you putted the links right (by copying) it automaticly finds its constraints?

RE: Chain
For example, create a part whose only purpose is to represent each of the links via a combination of sketch(es) and datums. Then, assemble the chain components to this part. One approach that has worked for us is to:
1. Create a sketch of the pitch line of your chain. This should be a tangent-continuous sketch composed of lines and arcs.
2. Join the sketch curves (Insert > Curve from Curves > Join) to create a new, single, continuous curve.
3. Create a new sketch representing every single link in the chain. (Tedious, but depending on what you want to achieve with this model, very useful). Mate the link ends to the Join Curve above. A simple angle expression can enable you to animate the chain links. Think about it...
4. Use a creative combination of datums, referencing your new "Chain Link" sketch, to give your eventual chain assembly robust mating datums.
5. Finally, make a new assembly, assemble this "design master" into it, and then assemble all your little links and pins to the "design master".
Hope this helps.
