Spring Washers

A double coil spring washer is a type of washer designed with two coils or helical springs, which provide enhanced spring action compared to single coil washers. These washers are typically used in applications where increased load-bearing capacity, resilience, or resistance to loosening is required. The double coil design offers more flexibility and compressive strength, making them ideal for heavy-duty or high-stress environments.

Key Features of a Double Coil Spring Washer:

1. Double Helical Coils: Unlike single coil washers, double coil washers feature two coils that are wound together, providing greater elasticity and a higher spring force.

2. Material: They are typically made from spring steel, stainless steel, or other materials that provide strength and flexibility to withstand the compressive forces and vibrations they are exposed to.

3. Function: When a fastener is tightened, the double coil washer compresses and exerts a spring-like force that resists loosening due to vibrations or external forces. The dual coils offer a more stable and consistent force compared to single coil washers.

Benefits of Double Coil Spring Washers:

• Increased Load Resistance: The dual coils can handle larger loads and higher compression, making them suitable for more demanding applications.

• Vibration Resistance: Like other spring washers, they resist loosening due to vibration or movement, but the double coil design offers superior performance in applications with frequent or high-intensity vibrations.

• Compact Yet Effective: Double coil washers often take up less space than other types of locking mechanisms (like lock nuts or split washers) while offering comparable or superior performance.

• Durability: These washers can last longer under heavy stress, providing a more reliable long-term solution.

Applications of Double Coil Spring Washers:

 

• Automotive: In car engines or other automotive components where high vibration is common, double coil washers help keep fasteners tight.

• Industrial Machinery: In machines or equipment that undergo frequent movement, these washers help maintain secure assemblies by absorbing shock and preventing fastener loosening.

• Construction Equipment: Heavy-duty machinery and equipment often use double coil washers to ensure tight connections under harsh conditions.

A wave washer is a type of spring washer that has a wavy, undulating shape. The washer is designed to provide axial load and create a spring-like effect when compressed. These washers are commonly used in applications where vibration, shock absorption, or the need for a constant compressive force is required.

Key Features of a Wave Washer:

1. Wave Shape: The washer has multiple waves or undulations, which give it flexibility. These waves compress under load, creating tension that resists loosening.

2. Material: Wave washers are typically made from spring steel, stainless steel, or other materials that offer good elasticity and strength.

3. Size: Wave washers come in a variety of sizes, based on the diameter of the fastener they are designed to fit. The key measurements are the inner diameter (ID), outer diameter (OD), and thickness.

4. Function: When the wave washer is compressed, the waves flatten out and push back against the applied load, offering a spring effect. This helps absorb vibrations and prevents loosening of fasteners.

Applications:

 

• Shock Absorption: Wave washers help absorb shock and vibrations in machinery or automotive parts.

• Electrical and Electronics: In devices like motors and gears that experience frequent movement or vibration.

• Prevent Loosening: Like other spring washers, they prevent nuts and bolts from loosening due to movement or vibration.

• Compact Designs: Wave washers are often used in applications where space is limited but a reliable spring action is needed.
