Re: Integrating Encoder Into Gearbox
You are being too concerned with space in your design. Poke the shaft 3/8 - 1/2" past the gearbox plate, and put the set screw on the other side. That's what we do.
When you *turn* the hole into the shaft, finish it with a reamer. You'll get a nicer fit. Probably a .2505 reamer.
For mounting, we've been bending a lexan z out of 1/32" lexan and using that to constrain the encoder torsionally. It seems to be working fine. There should be some pictures on our picasa site of how we've solved this exact problem before.
