How Do You Make a Chain and Sprocket in SolidWorks?

by

In this tutorial, we will learn how to create a chain and sprocket in SolidWorks. Chains and sprockets are essential components in many mechanical designs, especially in the field of robotics and machinery. SolidWorks provides powerful tools to model and simulate these components accurately.

Step 1: Creating the Sprocket

To start, we need to create the sprocket. Follow these steps:

  1. Open SolidWorks: Launch SolidWorks and create a new part file.
  2. Create a Sketch: Go to the Sketch tab and select the plane on which you want to create the sprocket.
  3. Draw the Pitch Circle: Use the Circle tool (Sketch > Circle) to draw a circle representing the pitch diameter of the sprocket.
  4. Add Teeth: Now, use the Line tool (Sketch > Line) to draw lines that represent each tooth of the sprocket. You can use dimensions and constraints to ensure accuracy.
  5. Create Cut Extrude: Select all the tooth profiles and use the Cut Extrude feature (Features > Extruded Cut) to remove material from the base circle, leaving behind only the teeth.

Step 2: Creating a Chain Link

The next step is to create a chain link that will be repeated along with our sprocket. Here’s how you can do it:

  1. Create a New Part File: Open a new part file in SolidWorks.
  2. Create a Sketch: Select the plane where you want to create the chain link.
  3. Draw the Chain Link Profile: Use sketch tools such as Line, Arc, and Circle to draw the profile of the chain link. Make sure to include features like pins or holes that will connect the links.
  4. Create a Revolve Feature: Once you have drawn the profile, use the Revolve feature (Features > Revolved Boss/Base) to revolve it around an axis. This will create a three-dimensional chain link.

Step 3: Assembling the Sprocket and Chain

Now that we have both the sprocket and chain link ready, let’s assemble them together:

  1. Create a New Assembly File: Open a new assembly file in SolidWorks.
  2. Add Components: Insert both the sprocket and chain link parts into the assembly by going to Insert > Component > Existing Part/Assembly.
  3. Mate Components: Use mates (Mates) to position and constrain the sprocket and chain links correctly. You can use mates like coincident, concentric, and distance mates for this purpose.
  4. Create a Pattern: If you want multiple instances of chain links around your sprocket, you can create a pattern using features like Linear Pattern or Circular Pattern.

Congratulations! You have successfully created a chain and sprocket assembly in SolidWorks. You can now further customize your design by adding additional features like guards, bearings, or adjusting parameters such as pitch diameter or number of teeth.

Remember to save your work regularly and experiment with different settings and configurations to achieve the desired design.

Happy designing!
