Question

internal ring gear...

Hi folks,

I need to generate an internal tooth ring gear. The PD and # of teeth, etc.
are designed, but I am not happy with the accuracy of the CAD geometry I
found downloading a sample from SDP. (SDP has a 24 pitch 6" ID, I need a
10", but the tooth profile on their model is a simple straight tooth
approximation) Would anybody out there know of a good source for that type
of geometry for download? I don't want to go through the exercise of
generating the involute profile, but I need something close for
presenting...

Thanks a lot!

    Well, I did learn something that I will pass on.

    I got the usual links to MCAD central, etc. where one can find some examples
    of gears - not really any internal spurs like I needed, but thanks to all
    who took the time to respond.

    Someone mentioned Boston Gear, which I had forgotten about. Thanks for that
    link. But the models that you can download from there (once you figure out
    how to use their site) are Pro|E neutral files.

    I did find via Google, the set of engineering calc worksheets called MITCalc
