Roller Chain Model
Roller Chain Model
(OP)
Hi,
I am trying to model a roller chain.
Like a bike chain
They are in a complete circle.
How do I array the links to get the exact diameter.?
I have tried calculating the pcd from the 152mm pitch
I have tried calculating the radius from the pitch x number of links, the smallest error is thrown out by Solidworks.
Any Ideas.?
thanks
Howard

aitchem ... To save time, can you ZIP and post the parts and assy for review?
RE: Roller Chain Model
if you array a straight segment around a circle, you will always get an error.....it's all about Pi !
I ran into this same "problem" and ended up using a Mate to locate an axis of one link to the next within a tolerance, however this was only on the sprocket that I wanted to be dimensionally correct; when the chain went to a straight line, the links were exactly pitched, e.g. axis of one link mated to the next.

Thanks wiliedawg
The tip about mate tolerances will crack it I think.
