How much of a gear reduction do you have there?

I can't recall the exact numbers off the top of my head, but each gearbox has a drill and an atwood in it.

In high gear our final speed is about 10fps.
In low, it's 1.5 fps.

Our wheel diameter is 6". If you want to figure out the exact reduction, feel free

looks to me that they are matching RPM's then using the drill as a torque booster

Canadian Engineering

We are canadian too. Our gear box is different from this one only in that it is more compact.
Great minds think alike.

very nice indeed

Harrison, Sean and the rest of team 783:

Very nice gearbox and drivetrain. This is a robust design which is very well laid out with large bearings. I really like how the drill motor is simply an input device, and if FIRST would change that motor next year, it won't change your design much.

Also, nice use of extrusions to the benefit to get your chain tension to your front and back wheels... the most efficient way to do a 4 wheel drive.

One question: How do you switch gears? Is that device hidden, or just not installed yet?

Andy B.

We're using a little pneumatic cylinder on each gearbox to shift.

They are installed and functioning now, but no pics to upload of that just yet. They'll be up soon.

Thanks for the compliments!

Yes the design may look familiar.

Special thanks goes to Team Epsilon Delta (Team 116) and especially Dave Lavery for their Dual-motor, dual-speed drive transmission design.

Re: Image Discuss: 783 Almost done...(1)

nice tranny... if you guys ever have weight trouble, though, those bearings on the transmission could definitly br less bulky.. i think we use those in our rookie year and they can get weighty and excess.... but nice manufacturing
