drills and gear housing...

Coach on team #419, Rambots, from UMass Boston / BC High and NONE AT THE MOMENT! :(.

does anyone have pictures of their bots in the past years with their gear housing used as a mount for the drills?

a description will go a long way too…

at the moment, although we’d rahter mill a pretty looking mount for our drive motors, we do not have the luxury. on the other hand, we would also settle for the gear housings for the drills if we could spraypaint them a different color.

So basically, i’d like to how people have modified (cut?) their drill motor housings in the past years…

thanks…

the past few years we have pretty much just zip tied the motor to the frame, it held ok, last year we made a mount, just a hole drilled in 1/4" aluminum plate, to fit the housing into. it worked good. another thing we found is that to let the motor float just a little. if you strap it down too tight, that puts all the work force on the shaft, not always a good thing… good luck guys -rich

If you really do it right, your drive shaft will be mounted on it’s own bearings. The white papers recommend it. You’ll never be wrong for doing it, but may pay a costly price for not doing it.
Good Luck

There are a variety of cheap and easy ways to mount the drill motors to the robot. First of all, a pretty easy way is to put it on a plywood platform where you cut out parts of the plywood (well, really sand down) so it matches up to the shape of the housing. In that case you probably want some sort of plywood bolted above the drill with the same cut out parts to match the top of the drill. Other things you can do can be to cut off the handles of the drills to give a flat mounting point. You can also bend sheet metal around the drill to keep it in place. If you do any of the “floating drill” ideas make sure you have a misalignment coupler inline with the drive shaft or you’ll be getting in a world of hurt.

We posted these pictures last year: http://www.geocities.com/elliotjo/
There are some close ups on our motor mounts. They worked out very well in the competition. The main problem we had with it was a misalignment with the motor output shaft and the shaft with a sprocket that it connected to. Also, we figured out it was a better idea to have two bearings holding that same shaft rather than just one and the gearbox.
The motor and gearbox were held on with three aluminum brackets. Each bracket had two parts. One was welded to the same plate as the others, and the second plates screwed down to the top of the others. The plates didn’t clamp down on the motors too much, it was mostly the shape of the motors and the plates that kept them in place. Sorry if that description makes no sense at all :-), hopefully the pictures will make more sense.

later,
