Creating straight bevel gear model in UG

The shape of straight bevel gear is relatively complex, and its surface is basically composed of curves and curved surfaces. The general commercial software UG can accurately describe the finite element of straight bevel gear.

The forging drawing of straight bevel gear obtained through the process is shown in the figure. After modeling, save and save a part in IGES format at the same time, which is convenient for importing to Pro / E to generate mold model.
