2&3. The gears on our CIM motors are not stem pinions. We had planned on stem pinions and using another bearing in the plate opposite the CIM motors, but decided we could save some weight and headaches by switching to a regular gear. the reason we have collars on the CIM gears is to 'pinch' the gear onto the shaft. We did this mainly because our team doesn't have any metric broaches and we didn't want to modify the CIM shaft. We have used this design previously in 2004 and it worked very well for us.

Thanks all for the kind compliments! Transmissions like this only happen when enthusiastic STUDENTS get involved in the design and build and constantly push the team to do better! Thanks Henry and Bunney you guys put in alot of time convincing the team we needed a dual motor drive and even more time machining your wishes.

Thanks Cliff for believing in us!
