    What rack and pinion for direct drive to use.

    I have just bought some new Gecko G202's that will run a 270oz and 1200oz stepper. I now need to know what size pinion and rack that i need to buy. Like what angle/pitch, how many teeth etc.



    Also where to buy from, I am in Australia. I do not mind buying from over-seas.

    Cheers

    Peter

    I believe Misumi will ship to Queensland out of Singapore, They have a huge free catalogue full of hardware. Although they do not appear to stock 14.5deg pressure angle rack. But 20deg is fine especially if the load is not really heavy. For a small table you could go with 20 diametral pitch with 12 at the largest.

    This is their worldwide website http://www.misumi.co.jp/world/index.html
    Here in N.A. Boston Gear is a very cost effective supplier but I suspect they may not be available in Australia.
