No drawings that we wish to share with other teams on the shafts sorry...
We have drawings, but I and I think WE (THE TIGERTRONS) feel that you should do some designing/calculating on your own.
I feel that building/designing a transmission should not be something that you can just build from a piece of paper.
Our team went out on the branch in the 2004 season and built this transmission from scratch with little help from outside sources. This was the first transmission we have ever built; we always used the drill motors and transmissions on our robot since 1996, up until the 2004 season.
None the less they worked!
I will give you these important dimensions though:
The biggest part diameter of this shaft is 1''
The smallest is 3/4'' to allow for output gearing/smaller bearings
The ball bearings we used were 5/16''
The inside hole for the shaft is 33/64''
The plunger that pushes the ball bearings into the gears is approximately 1/2''
The smaller hole that keeps the 5/16'' ball bearings from fall through the shaft is 9/32''
