Resortes de Plato

Resortes de Plato

Los resortes de plato, también conocidos como arandelas Belleville, son componentes con alta capacidad de carga axial y comportamiento no lineal, diseñados para soportar grandes esfuerzos en espacios reducidos. Su forma cónica y compacta permite aplicaciones en las que otros resortes no podrían operar con la misma eficiencia. Gracias a su deformación controlada, estas piezas se utilizan especialmente en proyectos que requieren resistencia a cargas elevadas con respuesta proporcional.

Unlike helical or flat springs, disc spring geometry favors uniform stress distribution, contributing to greater stability of the mechanical assembly. They are frequently applied in clutches, industrial brakes, safety valves and thermal expansion compensation systems. Versatility and robustness make this part a high-performance technical choice.

How do disc springs work?

Unlike conventional helical springs, disc springs feature a conical profile and operate under axial compression. When subjected to load, they elastically deform, storing energy and returning to their original shape after the force is removed.

This behavior provides: high stiffness, immediate response, controlled shock absorption, and reliable load retention. Which makes them ideal for systems that require precise motion control or energy absorption.

Industrial applications

• Safety valves – ensuring proper sealing under sudden pressure changes
• Brake and clutch systems – providing consistent operating force
• Mechanical assemblies with variable clearance – compensating thermal or structural deformation
• Power generation equipment – such as turbines and industrial compressors

Their compact structure makes them suitable for environments with limited space, where high force with minimal displacement is required.

Disc springs vs. conventional spring models

A disc spring differs significantly from conventional springs in both geometry and load capacity. It is engineered for critical applications requiring high performance under concentrated loads and repetitive cycles. By arranging disc springs in stacks — parallel, in series, or combined — it's possible to tune load behavior and travel distance, optimizing system performance.

Advantages of stainless-steel and carbon-steel disc springs: Key benefits include: High corrosion resistance – especially in stainless steel versions, ideal for aggressive or humid environments. Superior durability – ensures long service life even under continuous high-pressure operation. Dimensional stability – maintains mechanical characteristics even under intense thermal variation. Compliance with international standards – ensuring technical reliability for demanding projects. WM Molas manufactures both carbon-steel and stainless-steel disc springs, delivering custom solutions tailored to each application.

Customization: disc springs made to specification

• Reduced production lead times
• Supply in various materials, including special alloys
• Performance testing and quality control
• Ensuring full functionality and application safety

One of the strongest demands in the industrial sector is the production of custom disc springs, designed with precise dimensional and material specifications. This requires not only advanced technology, but also applied engineering expertise and deep technical standards knowledge. Companies like WM Molas stand out by offering these advantages.
