Winch Coil Design

[Anonymous]

Hello,

I'm currently designing a wich and trying to use parameters to drive the dimensions of the winch. The drum has 2 flanches on both sides, so in total I now have an assembly with 3 parts. I have made a weldment.iam of this assembly for production purposes.

Next step in the process is to cut the coil for the cable that will be winded around the drum and partialy over a flanche. 

So this requires the coil to go over multiple parts in the assembly of the winch. The problem I'm having is that there is no Coil function in the Assembly mode. 

Are there anny other ways of making a coil pattern go over several parts? I have attached a .iam file of the drum and side flanches.

Thanks in advance!

An assembly file (*.iam) is only a list of hyperlinks to the part files (*.ipt) and a record of assembly constraints (and a bit more).

You must include the part files.

Ive not seen your model because there are no ipt's. as stated above. So I'm guessing your design a bit. I think from what you have stated that it looks a bit like a cotton reel...

I would create anther ipt to represent the cable. Then start with a 3d sketch and create a helix, then sweep a circle along this helix. Then constrain the CL of the helix to the centre of the cotton reel and the two origin planes that intersect the helix to the origin planes of the cotton reel.  You can then sketch the rest of the cable route and sweep along that.

Sketches in assemblies are not recommended, (well where i work) because they can be problematic, ie loose their origin points etc.

Oops, I forgot to include the parts lists

Here are the corresponding .ipt files.

Mean while I have tried some things myself like deriving this .iam and then using the coil function to cut away material.

I'm not sure if this is the "right" way or if there is a better way to making a coil cut away material from multiple parts.

Edit: The welds might be out of place in this file because I'm still continuing to work in this file. So you can ignore the welds.
