Disc spring washers

Description

A disc spring, also known as a Belleville spring or conical spring washer, is a type of spring that consists of a conical or disc-shaped metal washer.
It is designed to provide high load capacity and deflection while occupying minimal space.
Here are some key features and common applications of disc springs:

Features:
Conical Shape: Disc springs have a conical shape, with a larger outer diameter and a smaller inner diameter. This shape allows them to exert a high force or load capacity while maintaining flexibility and deflection.

Stackable Design: Disc springs can be stacked in series to increase the load capacity or adjust the amount of deflection. By adding or removing discs, the desired spring rate and load characteristics can be achieved.

Material Options: Disc springs are typically made of high-quality spring steel or stainless steel to provide durability, corrosion resistance, and fatigue resistance.

Common Applications:
Bolted Joints: Disc springs are commonly used in bolted joints to provide preloading and maintain tension in applications where maintaining clamping force is critical. They compensate for relaxation or settling of the joint over time, ensuring proper engagement of fasteners and preventing loosening.

Vibration Damping: Disc springs are utilized in applications subjected to vibrations or dynamic loads. They act as shock absorbers, dampening vibrations and reducing the risk of fastener loosening or failure due to excessive movement.

Mechanical Assemblies: These springs find applications in various mechanical assemblies, including valves, pumps, and industrial machinery. They provide controlled deflection, compensate for thermal expansion or contraction, and maintain the desired force or tension in the system.

Heavy-Duty Applications: Due to their high load capacity and compact design, disc springs are suitable for heavy-duty applications such as heavy machinery, construction equipment, and aerospace systems. They provide reliable and consistent spring force under demanding conditions.

Safety Devices: Disc springs are used in safety devices and systems that require controlled release or activation at a specific force threshold. They can be designed to provide precise force application and ensure proper operation of safety mechanisms.

When using disc springs, it is important to consider factors such as the desired force, deflection, and number of springs to stack based on the specific application requirements. Proper installation and torque control should be followed to ensure optimal performance and longevity.
