Re: Engaging Gears Perpendicular to Shaft Direction?

If I were going to make a transmission that used the swing in type system to engage the gears, I would make the swing-arm movement such that it bottoms out or stalls out against a fixed flat on the gearbox to set the mesh at the perfect distance. This would be a perfect location to also simply screw the movement to the gearbox to lock it into gear or 'latch' it in like a swining gate. I can imagine some sort of ball screw driving the assembly back and forth or maybe two opposing swing arms for the two gears such that FWD on the motor brings one in and the other out and vice versa. Not sure if I would trust an Air cylinder for this unless it was fairly substantial or it pushed on a lever fairly far from the pivot point.
