High Quality Indusrial Spring

Manufacturers and Suppliers of Disc Springs

A disc spring, also known as a Belleville washer or conical spring washer, is a conical-shaped metallic washer that provides a high load capacity and deflection in a small space compared to other types of springs. Here are the key characteristics and applications of disc springs:

Advantages of Disc Spring:

Compact Size: Occupies less space compared to coil springs for the same load capacity.
High Load Capacity: Capable of bearing high loads.
Customizable Performance: Load and deflection characteristics can be altered by stacking multiple springs.
Durability: Resistant to fatigue and can withstand repeated loading and unloading.

Applications

Industrial Machinery: Used in clutches, brakes, and shock absorbers.
Aerospace: Employed in landing gear and other high-load components.
Automotive: Used in suspension systems and vibration dampening.
Valves and Pipe Flanges: Ensures tight seals under high pressure.
Electrical Contacts: Maintains constant pressure for reliable electrical connections.

Disc Spring Characteristics

Shape: Conical or truncated cone shape.
Material: Typically made from high-strength steel, stainless steel, or other alloys.
Load Capacity: Can support high loads with relatively small deflections.
Stacking: Can be stacked in series or parallel to modify load and deflection characteristics.

Design Considerations

Dimensions: Inner and outer diameters, thickness, and height.
Material Properties: Tensile strength, elasticity, and corrosion resistance.
Load-Deflection Curve: Ensuring the spring operates within its elastic range without permanent deformation.
Environmental Factors: Temperature, corrosive environments, and dynamic loading conditions.
Disc springs are versatile components widely used in various industries due to their ability to handle high loads in confined spaces and their adaptability to different configurations and performance requirements.
