Re: [CAD_CAM_EDM_DRO] Rotary to linear translation - an interesting idea.

Imagine two gear side by side bolted together one is twisted relatative to the other to move the teeth slightly off from the other taking up the slack. The two halfs of the anti-backlash gear equal the thickness of the mating gear. This works with spur and worm gears.

Terry.

How are antibacklash gears made?
