Drawing Gears In Solidworks

Introduction to Drawing Gears in SolidWorks

SolidWorks is a powerful 3D CAD software that can be used to create a variety of mechanical components, including gears. Gearing is a complex subject and it can be difficult to know where to start when designing a gear in SolidWorks. In this article, we will provide a step by step tutorial on how to draw gears in SolidWorks.

Creating the Base Gear

The first step in creating a gear in SolidWorks is to draw the base gear. This can be done by creating a sketch of the gear on the x-y plane. The sketch should include the outer and inner diameters of the gear, as well as the number of teeth. Once the sketch is complete, it can be extruded to create the base gear.

Adding Tooth Profiles

Once the base gear has been created, it is time to add the tooth profiles. This can be done by creating a new sketch on the top face of the gear. This sketch should be the same as the original sketch, except the teeth should now be drawn in. Once the sketch is complete, it should be extruded to create the tooth profiles.

Creating the Pitch Circle

The next step in creating a gear in SolidWorks is to create the pitch circle. This can be done by creating a sketch on the top face of the gear. This sketch should be concentric with the outer diameter of the gear and should be the same diameter as the pitch diameter. The pitch diameter is the distance between the two pitch points of the gear. Once the sketch is complete, it should be extruded to create the pitch circle.

Adding Fillets and Chamfers

The final step in creating a gear in SolidWorks is to add fillets and chamfers to the gear. This can be done by creating a new sketch on the top face of the gear. This sketch should be a circle concentric with the pitch circle and should be the same size as the fillet or chamfer. Once the sketch is complete, it should be extruded to create the fillet or chamfer.

Conclusion

Drawing gears in SolidWorks can be a complex process. However, with the right steps and techniques, it is possible to create a high-quality gear in SolidWorks. In this article, we provided a step-by-step tutorial on how to draw gears in SolidWorks. We started by creating the base gear and then added the tooth profiles, pitch circle, and fillets and chamfers. With a bit of practice, you should be able to create gears in SolidWorks with ease.
