Reverse Engineering Gears
Reverse Engineering Gears
(OP)
I have a gear that I want to figure out the information on. I do not have a cmm with reverse engineering capabilities.
Can I use traditional gear inspection methods (dimension over pins, span, #teeth, etc...) to figure out the gear data of this particular gear?
Is there a sequence of steps that I need to take in order to achieve such a thing? Maybe there is a simple calculator out there for standard gear sets?
please advise.

RE: Reverse Engineering Gears
Yes you can.
The only thing that'll throw you is working out the helix angle.
The only way that this can be done *properly* is by setting up the sample (or the mating part) on either a hobber or CMM.
Use Google to help you find the math you'll need to learn.

The hardest part will be trying to work out if and how much addendum correction has been used.
Once again, Google can be your friend.
When you're done, come back with the data and we'll help you confirm your results.

This is the procedure I will follow.

This will help you work out what the pitch & pressure angle is.
