610's Preseason Drive

[Avram Kachura]

This year for our pre-season drive train, we wanted to take a different approach to our design. Instead of having a 2 stage gearbox, we wanted to make it simpler by making a single stage 5:1 reduction using VexPro 60 and 12 tooth gears. We then used #25 sprockets to increase our reduction from 5:1 to 7.9 :1 using 14 and 22 teeth sprockets. We also decided to run the chain lengths inside the frame of our drive train to make it easier to assemble and access. As for the frame of the drive train, we decided on having the wheels inserted in a 2.5 inch box channel leaving the wheels enclosed and neatly tucked inside the drive train opposed to having it cantilevered or outside of our frame. Our estimate speed is 11.7 ft/second. reaching it in 1.8 seconds.

Drive train specifications:
- 6 wheel (Colson 4 inch)
- 4 motor gearbox (Designed for 6)
- 7.9:1 gear reduction
- # 25 chain
