Rotary Geared Pump Modelling and Assembly

Isometric view of the Rotary Geared Pump assembly.

In my ME 430 Introduction to Computer Aided Design class, I was taught how to model, assemble, and draw parts using Creo and SolidWorks. Learning how to use a CAD software is one of the most important topics I learned in college, as mechanical engineers would need to learn how to create an object and analyze its functions and properties for whatever use the object is designed for.

Problem

The final project of the CAD class is to create and assemble a Rotary Geared Pump using all of the knowledge I learned using SolidWorks. Schematics for the parts, as well as instructions on how to write the report were provided and explained by the professor. Additionally, several drawings for different parts and an assembly drawing with the Bill of Materials are needed for the report.

Solution

Most of the parts created usually relied on extruding the sketch and creating holes with extruding cut. The fillets are used for some parts to round out the edges. However, some other parts required the use of more advanced features such as revolve boss/base, lofted boss/base, mirror, revolved cut and hole wizard. The screws, nuts, and woodruff key were exported from the SolidWorks Toolbox. All of the parts were assigned a material based on what was given in the schematic. When all of the parts are made, they were all assembled to make the rotary geared pump seen on the right.
