Spring Washer Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A spring washer, specifically a disc spring or Belleville washer, is a conical-shaped washer that applies a continuous spring force against a nut or bolt head. When compressed during tightening, it creates axial tension that counteracts vibrational loosening in mechanical assemblies. In coupling mechanisms, it maintains preload on connecting elements, ensuring torque transmission reliability.

Working Principle

Works on the spring principle: when compressed between mating surfaces during bolt tightening, the washer's conical shape deflects elastically, storing mechanical energy as spring force. This force maintains constant pressure on the threaded connection, increasing friction at the thread interface and preventing rotation-induced loosening under dynamic loads.

Materials

Typically made from spring steel (SAE 1070-1095, AISI 1050-1095), stainless steel (AISI 302/304/316), or alloy steel. May feature zinc plating, phosphate coating, or dichromate treatment for corrosion resistance. Material hardness: HRC 40-50 for standard applications.

Frequently Asked Questions

How does a spring washer prevent loosening?

It creates continuous spring pressure that increases friction between threads, resisting rotational forces from vibration or thermal cycling.

Can spring washers be reused?

Not recommended, as repeated compression cycles can cause spring fatigue and loss of tension, compromising locking effectiveness.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
