Disc Springs

What Are Disc Springs?

Disc Springs, also known as Belleville washers, are conically shaped washers designed to provide a high load capacity in a compact space. They are widely used in various mechanical applications to absorb shock, maintain tension, and provide consistent force.


How Are They Made?

The manufacturing process of disc springs involves several key steps:

  1. Material Selection: High-quality materials such as 50CrV4, Stainless Steel 301, and EN 47 are chosen for their strength and durability. 

  2. Forming: The selected material is formed into a conical shape using precision machinery.

  3. Heat Treatment: The formed springs undergo heat treatment processes like austempering to enhance their toughness and fatigue resistance.

  4. Finishing: Post-processing includes grinding, shot peening, and surface treatments such as phosphating or powder coating to improve performance and longevity. 


Where Are They Used?

Disc springs find applications across various industries:

  • Automotive: In suspension systems, clutches, and transmissions to reduce shock and provide smooth functioning.

  • Aerospace: In aircraft landing gear systems and engines to ensure high performance and reliability. 

  • Industrial Machinery: In presses, punches, and stamping machines to support and absorb force during operation. 

  • Oil & Gas: In control valves, hydraulic cylinders, and drilling equipment to provide reliable pressure control. 

  • Medical Devices: In surgical instruments and prosthetic devices to provide precise tension and support. 


Importance and Significance

  • Space Efficiency: Disc springs offer high force in a compact design, making them ideal for applications with limited space

  • High Load Capacity: Their conical shape allows them to handle high loads without significant deformation.

  • Durability: With proper heat treatment and surface finishing, disc springs exhibit long service life and resistance to fatigue.

  • Versatility: They can be used individually or stacked in series or parallel to achieve desired load-deflection characteristics.


Advantages

  • No Deformation or Fatigue: Under normal loads, disc springs maintain their shape and performance.

  • High Energy Storage Capacity: They can store significant amounts of energy in a small space.

  • Long Service Life: With proper design and material selection, disc springs can last for extended periods.

  • Modular Design: Stacks of disc springs can be configured to meet specific load and deflection requirements. 


Key Features

  • Materials: Manufactured from materials like 50CrV4, Stainless Steel 301, and EN 47 for strength and durability.

  • Standards Compliance: Manufactured according to international standards such as DIN 2093 and DIN 6796. 

  • Customization: Available in various sizes and configurations to meet specific application needs.

  • Surface Treatments: Options include phosphating, powder coating, and shot peening to enhance performance. 


Frequently Asked Questions (FAQs)

Q1: What is the difference between disc springs and coil springs?
A1: Disc springs are conical and can handle higher loads in a compact space, while coil springs are cylindrical and may require more space for the same load capacity.


Q2: Can disc springs be used in high-temperature environments?
A2: Yes, materials like 50CrV4 and Stainless Steel 301 are suitable for high-temperature applications.


Q3: How are disc springs stacked to achieve desired characteristics?
A3: Disc springs can be stacked in series to increase deflection or in parallel to increase load capacity. 


Conclusion

Disc springs are essential components in various industries due to their high load capacity, durability, and space efficiency. Manufacturers in Gujarat, such as Khodiyar Spring Industries, Hindustan Spring Industries, and Gala Precision Engineering Ltd., provide high-quality disc springs tailored to meet specific application needs. Their adherence to international standards and commitment to quality ensure reliable performance in critical applications.
