Understanding Spring Lock Washers Types and Manufacturers
Spring lock washers are essential components in various mechanical assemblies, providing an effective means of locking fasteners in place and preventing loosening due to vibration or torque. With a variety of designs and materials available, understanding the types of spring lock washers and the companies that manufacture them can provide valuable insights for engineers, designers, and DIY enthusiasts.
Types of Spring Lock Washers
1. Helical Spring Lock Washers These washers are coiled in a spiral shape and are designed to provide a significant amount of spring tension. They are particularly effective in maintaining a tight grip on screws and bolts by exerting a continuous pressure against the fastener. The helical design allows them to flex as the fastener is tightened, ensuring a consistent locking force.
2. Toothed Lock Washers Toothed lock washers, also known as serrated washers, have sharp edges or teeth that grip the surface of the fastener and the material it is being fastened to. This type of washer is very effective in applications where there is considerable vibration, as the teeth dig into the surface, preventing any movement. Toothed washers are commonly used in automotive and machinery applications.
3. Flat Lock Washers Although not technically a spring lock washer in the traditional sense, flat lock washers can provide some degree of locking action and are often used in conjunction with spring washers. They help distribute the load of the fastener and can reduce the risk of damage to the surface being fastened. Their simplicity makes them a popular choice in numerous applications.
4. Wave Washers These washers are designed in a wavy or undulating shape. When compressed, wave washers provide a spring-like action, making them suitable for applications requiring shock absorption, including automotive and aerospace uses. Their unique design allows them to be utilized in confined spaces, offering a compelling alternative to traditional spring washers.
5. Belleville Washers Also known as conical washers, Belleville washers are disc-shaped and have a steep slope. They are effective in providing a pre-load force and can adjust to variations in load, making them suitable for applications that experience fluctuating stresses. The Belleville washer is commonly used in assemblies needing a stable, compressive force.
