In this SolidWorks tutorial we'll cover the calculations and methods of modeling a pair of spur gears that is used in a windmill water pump engine.

 

We'll begin this tutorial with a brief tour of the finished spur gear pair assembled onto a mounting stand while demonstrating how these two gears work together.

 

After exploring an Excel spreadsheet of gear calculations we'll then insert these values into a design sketch which will be used to drive the major features of each gear of our spur gear pair. To speed up the design process we'll then apply some design automation by embedding SolidWorks equations and global variables into some Smart Dimensions so that multiple gear designs can be created in just a few minutes.

 

In the end we create both our pinion and wheel gears of the windmill engine, assemble them together with our mounting stand then make them work along with a discussion of potential modifications that can be made to optimize our design.

 

Ultimately, you'll be leaving this SolidWorks training, not only with a good understanding and appreciation on how a spur gear pair is created, but also with a model that can be used for various other spur gear applications of your own design.
