Unlock the secrets of mate locking washers: a solidworks guide for professionals

Lock washers play a crucial role in securing bolted connections, preventing loosening due to vibration or dynamic loads. In SolidWorks, mating lock washers can be a challenging task, especially for beginners. This comprehensive guide will provide a step-by-step process to help you master the art of mating lock washers in SolidWorks, ensuring secure and reliable assemblies.

Understanding Lock Washers

Lock washers, also known as split washers or spring washers, are thin, disc-shaped components that are placed under the bolt head or nut to prevent loosening. They work by creating friction between the mating surfaces, ensuring that the connection remains tight even under external forces.

Step 1: Inserting the Lock Washer

1. Open the SolidWorks assembly and insert the bolt and nut components.
2. Click on the “Insert” tab and select “Component” from the drop-down menu.
3. Browse to the location of the lock washer file and insert it into the assembly.

Step 2: Positioning the Lock Washer

1. Select the lock washer and drag it into position between the bolt head and the nut.
2. Make sure that the lock washer is properly oriented, with the split ends facing outwards.

Step 3: Selecting the Mate Type

1. Click on the “Mate” tab and select the “Concentric” mate type from the drop-down menu.
2. Select the bolt head as the first entity and the lock washer as the second entity.

Step 4: Defining the Mate Parameters

1. In the “Mate Parameters” dialog box, ensure that the “Angle” value is set to “0” degrees.
2. Click on the “Reverse” checkbox to indicate that the lock washer should be on the opposite side of the bolt head.

Step 5: Selecting the Contact Point

1. Click on the “Contact Point” tab and select the “Edge Loop” option from the drop-down menu.
2. Select the outer edge loop of the lock washer as the contact point.

Step 6: Completing the Mate

1. Click on the “OK” button to complete the mate.
2. Repeat the process for the other side of the bolt or nut, if necessary.

Tips for Success

• Ensure that the lock washer is the correct size for the bolt or nut.
• Use a washer face to create a smooth contact surface between the lock washer and the mating component.
• Consider using a friction coefficient to simulate the actual friction between the lock washer and the mating surfaces.

Troubleshooting

• If the lock washer is not properly positioned, adjust the mate parameters or the contact point.
• If the lock washer is not mating correctly, check for any interference or gaps between the components.
• If the lock washer is not visible in the assembly, ensure that it is not hidden or suppressed.

The Bottom Line: Enhancing Assembly Integrity with Secure Lock Washer Mates

Mastering the art of mating lock washers in SolidWorks is essential for creating secure and reliable assemblies. By following the steps outlined in this guide, you can ensure that your bolted connections remain tight and functional, even under demanding operating conditions.
