Game-changing technique: mate lock washers with ease in solidworks
What To Know
- Select the outer edge of the lock washer and the corresponding edge on the mating surface.
- This will create a feature that defines the mate between the lock washer and the mating surface.
- Select a lock washer with an inner diameter slightly larger than the fastener shank and an outer diameter that fits within the mating surface.
Lock washers are essential components in mechanical assemblies, preventing fasteners from loosening due to vibration or movement. Mating these washers correctly in SolidWorks is crucial for ensuring the integrity and reliability of your designs. This comprehensive guide will walk you through the step-by-step process of mating lock washers in SolidWorks, empowering you to create secure and durable assemblies.
Understanding Lock Washers
Lock washers, also known as split washers, feature a split ring with slightly angled edges. When compressed, these edges bite into the mating surfaces, creating friction and preventing the fastener from rotating. They are commonly used in conjunction with bolts, nuts, and screws.
Selecting the Right Lock Washer
Selecting the appropriate lock washer size and type is essential for optimal performance. Consider the size of the fastener you are using and the amount of vibration or movement expected in the assembly. External tooth lock washers are suitable for applications where there is significant vibration, while internal tooth lock washers are ideal for lighter loads.
Step 1: Inserting the Lock Washer
Open SolidWorks and insert the lock washer into the assembly. Use the “Insert” menu and navigate to “Component” > “Standard” > “Washers.” Select the appropriate lock washer size and type.
Step 2: Positioning the Lock Washer
Place the lock washer between the fastener head and the mating surface. Ensure that the split ring is facing the fastener head. The washer should be positioned perpendicular to the fastener axis.
Step 3: Selecting the Mate Type
Select the “Mate” tool from the “Assembly” menu. Choose the “Coincident” mate type to align the lock washer with the mating surface. Select the outer edge of the lock washer and the corresponding edge on the mating surface.
Step 4: Applying the Mate
Click on the “Apply” button to create the coincident mate. This will align the lock washer perfectly with the mating surface.
Step 5: Adding a Concentric Mate
Select the “Mate” tool again and choose the “Concentric” mate type. Select the inner hole of the lock washer and the shank of the fastener. This mate will ensure that the lock washer is concentric with the fastener.
Step 6: Tightening the Mate
Click on the “Tighten” button to apply the concentric mate. This will fix the lock washer in place and prevent it from rotating.
Step 7: Checking the Mate
Use the “Check Mate” tool to verify that the lock washer is properly mated. The mate should be shown in green, indicating a successful connection.
Creating a Mate Feature
To create a permanent mate feature, select the “Mate Feature” tool from the “Assembly” menu. This will create a feature that defines the mate between the lock washer and the mating surface.
Key Points: Mastering the Art of Secure Connections
Mating lock washers in SolidWorks is an essential skill for engineers and designers. By following the steps outlined in this guide, you can ensure that your assemblies are secure and reliable. Remember to select the appropriate lock washer, position it correctly, and apply the necessary mates to prevent fastener loosening. With these techniques mastered, you can create robust assemblies that withstand the challenges of vibration and movement.
Frequently Asked Questions
Q1: What are the different types of lock washers?
A: There are various types of lock washers, including external tooth, internal tooth, Belleville, and wave washers.
Q2: How do I determine the correct lock washer size?
A: Select a lock washer with an inner diameter slightly larger than the fastener shank and an outer diameter that fits within the mating surface.
Q3: Can I use lock washers with any type of fastener?
A: Lock washers are primarily used with bolts, nuts, and screws. However, their effectiveness may vary depending on the fastener type and application.
Q4: How many lock washers should I use?
A: Generally, one lock washer is sufficient for most applications. However, in high-vibration environments, consider using two lock washers, one on each side of the fastener head.
Q5: Can I reuse lock washers?
A: No, lock washers should not be reused as they lose their effectiveness after being compressed.
