If you dislike chain so much, why did you choose to chain together your omni-wheels and traction wheels? From your models it looks like you have enough CAD experience to space and use timing belts. SolidWorks (at least, maybe Inventor does too) comes with a tool for calculating belt lengths that's very handy. Belts are quieter and don't need tensioning.
