Three-Dimentional CAD Modeling Of The Gear Reducer And Research On Parameterized Design Of Its Key Parts

After more than 40 years' development, the technology of CAD has the substantial progress, already transferring from two-dimensional CAD to three-dimensional CAD, and there has been mature three-dimensional CAD software in market. Currently, the technology of CAD has been applied to each field in industry production. The key of three-dimension CAD design is the modeling of three-dimensional solid, three-dimensional modeling includes line modeling , surface modeling, solid modeling , currently most popular feature-based modeling and parameterized modeling. Feature-based parameterized solid modeling is a integration of these modeling technologies.This paper undertakes research on the realization of three-dimensional parameterized CAD system of the gear reduce parts. Applying feature-based parameterized solid modeling method to the CAD design of the gear reduce key...
