Tutorial – Creating Helical Gear in SolidWorks?

by

Creating helical gears in SolidWorks can be a challenging task, but with the right techniques and knowledge, you can easily model these complex components. In this tutorial, we will guide you through the step-by-step process of creating helical gears using SolidWorks. So let’s get started!

Step 1: Sketching the Gear Profile

Before we start creating the helical gear, we need to sketch its profile. To do this, follow these steps:

  1. Create a new part in SolidWorks by going to File > New > Part.
  2. Select the Front Plane from the Feature Manager Design Tree.
  3. Click on the Sketch icon to activate the sketching environment.
  4. Draw a circle with the desired diameter for your gear.
  5. Create another circle, concentric with the first one, representing the base circle of your gear.
  6. Add construction lines to define the tooth profile.
  7. Create each tooth profile, ensuring that they are evenly spaced around the base circle.

Step 2: Extruding and Modifying Gear Teeth

Once you have sketched the gear profile, it’s time to extrude it and modify the gear teeth:

  1. Select all of your sketch entities by dragging a selection box around them.
  2. Right-click on your sketch entities, and choose “Convert Entities”. This will create a new sketch on a plane parallel to your sketch.
  3. Extrude the sketch by going to Features > Extrude Boss/Base.

    Set the desired thickness for your gear.

  4. To create the helical shape of the gear, go to Insert > Curve > Helix/Spiral. Set the desired pitch and height for your gear.
  5. Select the top face of your extruded gear and apply a circular pattern to create multiple teeth.
  6. Modify each tooth shape by using tools like fillets or chamfers. This will add realism and functionality to your gear design.

Step 3: Adding Keyways and Fillets

In order to make our helical gear fully functional, we need to add keyways and fillets:

  1. Create a sketch on one of the faces of your gear, where you want to add a keyway.
  2. Draw a rectangle, representing the keyway profile. Make sure it aligns properly with the gear teeth.
  3. Cut out the keyway shape by going to Features > Extruded Cut.
  4. To add fillets, select the edges that need filleting and go to Features > Fillet. Set the desired radius for your fillet.

Step 4: Finalizing Your Design

You are now in the final stages of creating your helical gear. Follow these steps to complete your design:

  1. Add any additional features or details to your gear, such as shaft holes or surface finishes.
  2. Apply appropriate material properties to your gear by right-clicking on the feature and selecting “Edit Material”.
  3. Create technical drawings of your gear by going to File > Save As > Drawing. This will help you communicate your design intent and specifications.
  4. Save your SolidWorks part file for future reference and use.

Congratulations! You have successfully created a helical gear using SolidWorks.

By following these steps, you can create gears of different sizes and specifications. Remember to experiment with different parameters and features to achieve the desired results. Happy designing!
