High Quality Indusrial Spring

Manufacturers and Suppliers of Belleville Spring

A Belleville spring, also known as a conical or disc spring, is a type of compression spring characterized by its unique shape. Here are the key features and applications of Belleville springs:

Key Features

Shape: Belleville springs are conically shaped, resembling a washer or a disc.
Load Distribution: They provide high load-bearing capacity in a small space, making them ideal for applications where space is limited.
Deflection and Load: The deflection and load characteristics of a Belleville spring can be adjusted by stacking multiple springs in parallel or series, allowing for customization of spring properties.
Material: Typically made from high-strength steel alloys, stainless steel, or other durable materials to withstand high stress and environmental factors.

Applications

Vibration Damping: Used in applications requiring vibration damping and shock absorption, such as in machinery and automotive suspensions.
Preload of Bearings: Commonly used to maintain the preload in ball bearings, ensuring consistent performance and longevity.
Thermal Expansion Compensation: Employed in assemblies where thermal expansion or contraction is a concern, as they can accommodate changes in length.
Load Distribution in Bolted Assemblies: Used to distribute load evenly in bolted assemblies, preventing loosening due to thermal cycling or vibration.
Valve Actuation: In valves and actuators, where precise force control is needed.

Advantages of Belleville Spring

Compact Design: High load capacity in a small form factor.
Customizable: Load-deflection characteristics can be tailored by stacking configurations.
Durable: Made from materials that can withstand harsh conditions and high loads.

Example Use Case

In a bolted flange joint, Belleville springs can be used to maintain a constant tension on the bolts, compensating for thermal expansion and contraction. This ensures that the joint remains secure under varying temperature conditions, preventing leaks and maintaining the integrity of the assembly.

By leveraging the unique properties of Belleville springs, engineers can solve complex mechanical challenges in a wide range of industrial and commercial applications.
