kicker pull back? possibly power a winch? either way I'd bet those anti back drive pins are still in that dewalt

[Andrew Schreiber]

Nice to see the Bees are hanging Eric. Let's have some more details. Standard TB and standard NBD transmission on the CIM? (3/4/12) Locked in 1st gear? 36:1 reduction? If I recall there are back drive pins which I assume you left in place.

Knowing the bees this is for some sort of arm. Turreted?

[Eric Yahrmatter]

The Dewalt is in 1st gear, and after the Toughbox, we end up with a 153:1 reduction...I wonder what this is for...hmmm

Looks like what we were about to make tonight when our arm didn't pull the robot up. Then we just unjammed the arm :D Bigger sprocket is working wonders too, lifted me up no problem in a power test. Scary as all get out...

Something very slow with a ton of torque... Forklift?

[billbo911]

Following Dr. Joe's example (http://www.chiefdelphi.com/forums/showpost.php?p=913204&postcount=15), this set up should provide 34,780 Oz-in. of stall torque at about 35 RMP.
With 180 Lb-Ft of torque, lifting a robot is an easy proposition. :yikes:

[Kevin Sevcik]

Definitely makes for easy lifting if potentially... sedate. Given that a 153:1 gear down leaves your end effector turning at about 35 RPM. At 2 seconds per revolution, one would hope you're not planning on needing more than one revolution to complete a lift....

Where do you get the dewalt transmissions? Do you have to buy a whole drill?

[Mr.G]

I think they are planning on lifting there whole alliance. :ahh:

You do not have to buy the whole drill. Dewalt parts can be purchased here:
http://www.dewaltservicenet.com/Products/DocumentView.aspx?productid=75463&typeId=19037&documentId=37924

You will need items 42 (outer case) and 61 (transmission assy) to get this to work. Follow the instructions in the Nothing But Dewalts whitepaper:
http://www.chiefdelphi.com/media/papers/1592

Total cost for the transmission parts is $122.95. I have seen it cheaper elsewhere in the past though.

[daltore]

We've somehow found a source for $55 DeWalt drills (the whole thing minus the batteries). I think. I'll ask our mentor tomorrow if you'd like.

[sanddrag]

I think they are planning on lifting there whole alliance. :ahh:Remember guys, power equals work over time. Losses neglected, any motor can move any load, it's just a matter of time.

[Bruceb]

daltore, Yes if you could find a better price that would be great.
Thanks
Bruce
