This is where I'm going to need a mechanical engineer with a little more experience than me...
1. With how much force will they want to push each other apart? I assume that this actually varies... so I guess I'm looking for the maximum force. I assume this is some ratio of the torque.
and the other obvious question is:
2. In which direction is this force applied? As for direction, I assume a significant amount of the force is pushing them directly tangent to where the teeth mesh, but I think this is this too much of a simplification. Is the direction actually related to the gears' pressure angle? What about with mutiple teeth engaging? This seems like it could develop into a rather complex problem...
I'll guess it's something like (T / (D/2))*SIN(PA) is the force pushing them apart in the plane of the shaft centers... but I'd really appreciate it if someone had something better than a guess.
Thanks in advance,
Matt
