Single-layer wave spring washer wave disc washer stainless steel/17-7PH (SUS631)


Wave washers, also referred to as wave springs, are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. Many design variations have evolved to best serve these basic functions. Wave spring washers, also called wave washers, generally have several curvilinear lobes. The wave washer is an efficient washer for obtaining loads when the load is static, the working range is small, and the amount of axial space is limited.

What are the different types of wave washers?

Wave spring washers are load-bearing devices that provide a preload between two surfaces. Other common types include flat washers, C-washers, D-shaped washers, countersunk or finishing washers, fender washers, SAE washers, torque washers, and shoulder washers.

Le rondelle ondulate sono suddivise in tipo WG tipo WL tipo WN

Rondella elastica ondulata WG

The WG-type wave spring washer is an open-type elastic washer that can usually be installed in a small space, such as by applying prestress to the bearing, reducing the noise of bearing operation, and improving the running accuracy and stability of the bearing. In addition, there are also a large number of electronic appliances. The application materials include carbon steel, stainless steel, copper alloy, etc.

Rondella elastica WL Wave:

The WL-type wave spring washer is a lap-type elastic washer, which can usually be installed in a small space, such as by applying prestress to the bearing, reducing the noise of the bearing running, and improving the running accuracy and stability of the bearing.

Rondella elastica WN Wave:

The WN-type wave spring washer is a multi-layer wave crest overlapping elastic washer. Compared with the WL type, this series is composed of multiple layers of materials, so the K value curve under the same compression stroke is flatter than the WL type, which is suitable for larger elastic forces. In the case where the elastic release of the entire working stroke is required to be more uniform.

In the world of engineering and manufacturing, precision and reliability are paramount. Small components often play a crucial role in ensuring the overall success and safety of a product. One such unassuming yet essential component is the wave spring washer. This article will delve into the intricacies of wave washers, exploring their design, functions, advantages, and diverse applications across various industries.

Wave Spring Washer: A Brief Overview

A wave washer, also known simply as a wave washer or wave spring, is a type of washer that exhibits a distinctive wavy or corrugated profile. This unique design imparts special mechanical properties to the washer, making it highly versatile and effective in a wide range of applications. Typically made from materials like carbon steel, stainless steel, or beryllium copper, wave spring washers are known for their ability to provide controlled axial load and maintain assembly tension.

Design and Functionality

The primary design feature of a wave spring washer is its undulating or wave-like shape. This shape allows the washer to compress and expand radially when subjected to axial loads. When compressed, the waves flatten out, and when the load is released, they return to their natural wave shape. This dynamic behavior enables wave washers to perform several key functions:

  1. Load Distribution: Wave spring washers distribute loads evenly over the contatto surface, reducing the risk of damage to the components they are installed between.
  2. Compensation for Thermal Expansion: They compensate for thermal expansion and contraction in assemblies, maintaining proper tension even under temperature variations.
  3. Vibration Damping: Wave washers can absorb vibrations and reduce noise in machinery and equipment.
  4. Preloading: They are commonly used for preloading bearings and other critical components, ensuring optimal performance and extending servizio vita.

Applications in Engineering

Wave spring washers find applications across a wide spectrum of engineering disciplines.

  1. Automotive Industry: In automotive applications, wave washers are used in suspension systems, clutch assemblies, and engines to absorb vibrations and provide preloading.
