Cutting Gears out of Plastics

This looks a lot like 3476’s 2019 turret gear.

Team 3476: Code Orange 2019 “Cloudbreak” Robot Reveal

[IMG_20190210_180803] [turret] We are using a custom-made roller pinion drive that basically consists of a pinion with rollers arranged in a circle and a large internal ring gear. The rollers are on bearings and rotate freely instead of sliding against the gear teeth, so it has very low friction. Due to the nature of the design, there is practically no backlash if it can be manufactured accurately. We made the ring gear on a CNC router and CNC milled the bearing holes on the pinion.
