Team 716, the Who’sCTEKs would like to share our 2002 dual motor gearbox design. The drawings are in AutoCAD R14 and are in a self extracting zip file. This shows a simple way to couple two motors using gears and sprockets. Key factors are shaft center distances and matching motor speeds.

This design gears the Atwood motor to match the Drill Motor in low. The chain setup allows the motors to spin in the same direction for troubleshooting. The same unit is used on both sides of the robot. One is located in the left rear, the other in the right front. Additional mounting holes were made 'at assembly'.

The drill transmission was modified according to the white paper 'Dr. Joe's Drill Advice'. The no-backup pins and clutch were removed and the setscrews were installed. The transmission was locked in low with a wire-tie. We did not use , but should have, 'Dr. Joe's Drill Shaft'.

Components are mostly from the kit and Small Parts. The main drive shaft material is from Stock Drive Products, www.sdp-si.com.

Notes:
1. Change to a variant of 'Dr. Joe's Drill Shaft' design. We broke four transmissions (the tabs on the final carrier) during finals at UTC-New England and at the Nationals.

2. Reduce weight where appropriate. Time constraints kept us from optimizing this.

3. Simplify the unit by gearing the motors together. This eliminates one plate and the sprockets/chain. The motors don't care if they spin in opposite directions.

4. Add heat sinks and/or additional fans.

5. Item #11 keeps the drill motor from torquing out of the transmission. We learned the hard way.
