Racks and Pinions

Dear CEIan,

I have been searching alot on internet this few weeks, but i could hardly get some idea on how to determine the tooth of my racks which i already determined it on my pinions. How to i looking on it to design my racks???

As my racks is 50mm diameter with 18 no.teeth. Module 2.75, Face width 40mm and its in 4.15 helix angle.

I got the tooth shape from Inventor. But, how to design the rack tooth shape to coincidents with my pinions.

Please help..

    I think we both have the same problem!
    These few days i keep searching on internet about the calculation for rack and pinion but i could hardly find one.
    Anyway, we can find it from misumi catalogue.
