For modeling a chain my approach would be to build a guide curve and then assembly the individual chain components to each other and then tether them to the guide curve - this would allow the chain to move along the guide curve if your intention is to eventually animate the entire assembly. based on the type of chain you are using this will dictate the required tooth dimensions.
The sprockets tend to be more standard tooth profiles - you should be able to look it up in a machinery's handbook. In most cases the extra geometry or modifications to the tooth profiles is proprietary to different manufacturers.įor a single speed set up things get much easier.
Most multi speed gear sets have lots of added features along with a traditional tooth profile. Modeling a real chain between multi-speed gears is a relatively difficult task - it is something I have wanted to do for a while but never can justify the time required.
