Re: Help Needed With Vex Ball Shifter

Ok -

So - I'm going to post the info I have. I'll be honest - I'm not sure how to calculate the gear ratios.


Ball Shifter is 3 cim Ball Shifter using 2 Cims with a 2.65 spread. The pinion gear attached is 12 tooth and the wheels have a 30 tooth gear on them.

The Single Speed is a WCP with 2 motors with a 44:30 ratio attached to the same gears on the wheels.

Wheels are 12 inch pneumatic taped to reduce friction.

As far as we can tell the air actuator is working correctly - we are using another to launch our catapult and that is working properly.

Let me know what else you need.

Thx,
Daniel
