Our team has been experimenting with 3D printed gear plates. Here’s a preseason release of a design that we might use this season, depending on the game.
The gearbox features a quick change cover for changing the 2nd stage gear ratio.
We used 3D printed gear plates in the offseason, trying to abuse them to see how they would hold up, and they held up. That includes an offseason event, practice driving, and some gratuitous wall ramming and ramp jumping. Those ones were simply printed versions of the flat aluminum plates we ran in 2018, and the general design was the same basic idea as this posted design. We’ve had an ABS set on one side of the robot and a PLA set on the other side since May. Both have survived with no apparent damage.
Our motivation for potentially using printed gear plates is to eliminate lead time and be
able to easily make our parts in house.
