Manufacturers and Suppliers of Disc Washer

A disc washer spring, also known as a Belleville washer, is a type of spring shaped like a washer but with a slightly conical shape. It is used to provide a flexible preload and absorb shocks in a bolted joint or other assembly. The key characteristics and uses of disc washer springs include:

Conical Shape: The washer is not flat but has a conical shape, giving it a spring-like property.
Elastic Deformation: When a load is applied, the washer flattens slightly, providing a controlled deflection and force.
Material: Often made of spring steel or other high-strength materials to maintain their shape and properties under load.
Load Distribution: Helps distribute the load evenly over a larger area, reducing stress concentrations.

Uses

Preload in Bolted Joints: Provides a constant force to maintain tension in bolted assemblies, preventing loosening due to vibrations or thermal expansion.
Shock Absorption: Absorbs shock loads and reduces impact forces in mechanical systems.
Compensate for Creep and Relaxation: Maintains tension over time even if the joint materials undergo creep or relaxation.
Vibration Damping: Reduces vibration and noise in mechanical systems.

Applications

Automotive: Used in various components like clutch assemblies and suspension systems.
Aerospace: Ensures reliable connections in high-stress environments.
Industrial Machinery: Maintains tension in machinery assemblies subject to dynamic loads.
Electrical and Electronics: Provides reliable contact pressure in connectors and switches.

Advantages of Disc Washer

Compact Design: Provides a high force in a small package.
Adjustable Load: By stacking washers in series or parallel, the load-deflection characteristics can be adjusted.
Durability: Made from high-strength materials, they are durable and resistant to wear and fatigue.
