The closest thing to an anti-backlash gear is the Conical gear (a misnomer).
It can be used to load a gear train. I have used this in a design by Iain
Hendry.

I have tried using a second motor in the gear train with a slight reverse
current. This pretty bulky.

I think the gear you want is a sandwich of two gears that are spring loaded
so the teeth oppose each other. This would work in a small gear train.

There is another example of the conical gear at the end of this page.

Tech question for us: Any body know what an Anti-Backlash gear is?

What set(s) include this "conical" gear?

Far as I can tell, these are the gears used in the gearboxes in 8880, 8448,
8480, and prob'ly others.
