Presentation Transcript

  1. Parametric Gears Presented by Stephen M. Samuel PE

  2. A customer has a gear program that didn’t do internal sun gears. It wasn’t friendly. The law curve capability in NX12 is excellent. You are able to quickly input four equations; t=1, xt=f(t) yt=f(t) and zt = f(t), then access the law curves ability on the curve tab. It will make the appropriate curve. In this case the equations perform the involute gear tooth profile.

  3. A law curve and other features were used to create a parametric model.

  4. Animation of the gear pair Animation done using “framenumber”

  5. The part file is used to make a few components

  6. An assembly is produced

  7. A laser cutter is used to quickly cut out the actual models
