Nx gear feature
Nx gear feature
(OP)
Hello everyone...
I'm trying to make a parametrized feature of a gear.
If someone have a tutorial or eaven a sample of how to do it, I would be greateful.

Tadej

RE: Nx gear feature
But this is to simple for me....I need a gear with corection and other details...
but thank you for the NX open programme...it is useful to see how thinks works.
Thank you,
Tadej

It is real basic.

RE: Nx gear feature
Very interesting approach to creating a gear tooth profile. One question though, why the offset curves (features #10 & 11).
Thanks in advance for your reply.

He did it in NX-5 for those one earlier releases.
This is the sort of thing I had been wanting for some time even though I'm not tuned into whether AGMA is the best or most common standard. Many of the gears we worked with are either SAE or Metric standard and the trouble is always that if you want to calculate and repoduce the involute geometry correctly then you've an uphill battle. One of the main problems is that access to information about the geometric detail of the involute form seems to be restricted to those willing to pay the standards orgainizations for their documetation.
I was therefore impressed to see how you had defined the involute and wondered if you would allow me to be ignorant enough to ask whether it is accurate or not?
I realise there are other examples available that do a passable job of putting teeth on a diameter but providing a correct involute tooth form that maintains a good contact angle is a different matter yet one highly to be desired given that we're using a high end CAD system to define such a common engineering mechanism.

The calculations for tooth width, depth, dedendum, etc. are based on AGMA standards. My job involves gearbox design with plastic molded gears, and AGMA standards work fine most of the time.
The involute equations are the same for metric or english gears, so with a bit of work my model could be converted to create a metric gear.
RE: Nx gear feature
I was wondering if you had any ideas about the part not updating correctly if I try making the gear larger than 1 inch. (say, 35 dp and 52 teeth). Do you get errors also?
