How Do You Use Bearing Fixtures in SolidWorks?

by

In this tutorial, we will explore the use of bearing fixtures in SolidWorks. Bearing fixtures are an essential component in mechanical engineering design, as they provide support and stability to rotating or oscillating parts. By using bearing fixtures, designers can accurately model and simulate the behavior of these parts within their assemblies.

Creating a Bearing Fixture

To create a bearing fixture in SolidWorks, follow these steps:

  1. Step 1: Open your assembly file in SolidWorks.
  2. Step 2: Go to the “Insert” menu and select “Component”. Then choose “New Part”.
  3. Step 3: In the new part document, sketch a cylinder using the sketch tools.
  4. Step 4: Extrude the cylinder to the desired length using the extrusion feature.
  5. Step 5: Save the part as a separate file. This will be your bearing fixture component.

Inserting a Bearing Fixture

To insert a bearing fixture into your assembly, follow these steps:

  1. Step 1: Go to the “Insert” menu and select “Component”. Then choose “Existing Part/Assembly”.
  2. Step 2: Browse for the previously saved bearing fixture part file and click “Open”.
  3. Step 3: Position and orient the bearing fixture within your assembly using the move/rotate commands.

Note:

In order for the bearing fixture to function properly, it must be aligned with the corresponding parts that it supports. Ensure that the bearing fixture is concentric with the shaft or any other rotating part that it interacts with.

Configuring Bearing Fixture Properties

After inserting a bearing fixture, you can configure its properties to accurately represent its behavior. To do this, follow these steps:

  1. Step 1: Right-click on the bearing fixture component in the assembly tree and select “Component Properties”.
  2. Step 2: In the Component Properties dialog box, go to the “Physical Dynamics” tab.
  3. Step 3: Adjust the appropriate parameters such as friction coefficient, damping, and stiffness according to your design requirements.

The values you set for these parameters will affect how your bearing fixture interacts with other parts in your assembly. It is important to understand these parameters and their impact on the overall system behavior.

Analyzing Bearing Fixture Behavior

SolidWorks provides powerful simulation tools that allow you to analyze the behavior of your bearing fixtures. By applying forces, motion, or other loads to your assembly, you can observe how the bearing fixtures respond under different conditions.

  • Static Analysis: Use static analysis to study how your bearing fixtures react under steady-state loads. This can help you determine if they are capable of supporting the required loads without failure.
  • Motion Analysis: Motion analysis allows you to simulate the movement of your assembly over time.

    By applying rotational or translational motion to specific components, you can observe how your bearing fixtures contribute to the overall motion of your system.

  • Stress Analysis: If you want to evaluate the stress distribution and deformation of your bearing fixtures, use stress analysis. This can help you identify potential weak points or areas of excessive stress.

Conclusion

In conclusion, bearing fixtures play a crucial role in mechanical design, providing support and stability to rotating or oscillating parts. With SolidWorks, you can easily create, insert, and analyze the behavior of these fixtures within your assemblies. By understanding the steps involved and utilizing the simulation tools available, you can ensure that your bearing fixtures perform optimally in your designs.
