Encoder Mount Kit Diametrical Pitch

Our team has been using the VexPro shifting gearbox encoder mount kits to mount Grayhill encoders to our custom gearboxes - for one of our designs, we need to use a different number of teeth on the large gear - we’re not sure what DP these plastic gears have, however. Does anyone know what diametrical pitch these gears have?

Look here.

It doesn’t seem like any of the documents specifically give the pitch of the gears - am I looking in the wrong place?

The ballshifter housing CAD file is also available at the Vexpro site.

Looks like the C-C distance from output shaft axis to Greyhill encoder axis is one inch.

The encoder gear has 12 teeth and the output shaft gear has 36 teeth.

DP = (12 + 36) / 2 = 24.
