I'm not a modeling expert, but I might be able to help with the mainspring. Here's what I did:

Start with a large circle and fill it in back and forth with 2 point circles along the X axis

Use Sketch trim to delete half of each circle to make a spiral pattern

Use sketch offset and close the ends to make a valid profile

Extrude the profile, and cut a hole in the end.

Hopefully that will at least give you an idea to work off. I attached the model in case you want it. Good Luck!

1. The Coil operation has a spiral option.

2. You need to provide more information. Do you need help designing a flat pulley with a crown or how to model the belt and pulleys?

This is a much better solution! Thanks for posting.
