[FTC]: TETRIX gear specs

[Nate Laverdure]

For posterity:
TETRIX gears have a diametral pitch (DP) of 32 teeth/in, a pressure angle (PA) of 20 degrees, and a face width of 0.250 in.

I'm lost as to what the purpose of this was?

[Nate Laverdure]

I thought I explained it pretty succinctly... I needed this information and I couldn't find it on ChiefDelphi or any other obvious place. So after doing the research to find the information, I shared it here for other people to use because I couldn't find a more appropriate place.

I think they're actually 0.80 module based on the dimensions of the CAD models that I downloaded. 0.80 module is equivalent to 31.75 pitch, so a custom 32 DP gear would work fine in any case. I'm not positive that the models match reality. If one measures the outer diamter of a 40 tooth gear, then if it's closer to 1.313" it's 32 dp, and if it's closer to 1.323" it's 0.80 module.
