Spring Washer Specification

A spring washer, on the other hand, is a type of washer that featured a curved shape. Unlike plain washers, they aren’t flat. Spring washers are curved. They can curve in different ways, but all spring washers feature a curved shape that prevents them from resting flush against a surface without the presence of a load.

Spring washers allow for the distribution of faster’s load as well, but they are particularly useful for applications involving vibrations. Vibrations can cause fasteners to loosen. If a fastener is driven into a machine or object that vibrates, it may loosen to the point where it comes out. Spring washers prevent this from happening. They provide an axial load that will secure the fastener in the object.

Types Of Spring Washers

Spring washers are disks of metal that are formed in an irregular shape so that when the washer is loaded it deflects, acts like a spring, and provides a preload between two surfaces. Spring washer types include adjustable spacers, Belleville washers, bowed or curved washers, conical washers, finger washers, and wave washers. Spring washers are typically used in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.

A Belleville Washer, also known as a Conical Spring Washer, Disc Spring Washer, Belleville Spring Washer or Cupped Spring Washer, is a type of spring that is shaped like a washer. Its shape gives the washer a spring characteristic. The benefits of Belleville washers include a long service lie, no setting or fatigue under normal loads and stresses, low creep tendency, high load capacity, efficient use of space, and high spring forces with low spring height. Belleville washers can be stacked to modify the spring constant or the amount of deflection to better meet a variety of application needs. Belleville washers are available in spring steel, stainless steel, and 410 stainless steel.

Wave washers, characterized by their undulating form, are specifically designed to provide a compensating spring force and sustain a load or absorb shock.

Applications for Spring Washers

A Spring washer also known as a helical spring is specifically designed to provide a compensation spring force and sustain a load or absorb a shock a spring washer is used to prevent components from loosening. The spring washer Provide hardened bearing surfaces to create more uniform torque control and provide more uniform load distribution through controlled radii section cutoff. Provide protection against looseness resulting from vibration and corrosion

Frequently Asked Questions

Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.

Washers are not always necessary but it is common practice to use them anyway. How do spring washers work? Spring washers add tension to a fastener assembly and are used to absorb a shock or vibrations.

The difference lies in their shape. Plain washers are flat, whereas spring washers are curved. For most applications, plain washers are typically used. For machines and objects that vibrate, spring washers are recommended
