What is a spring washer for?

In the field of mechanical engineering and manufacturing, spring washers are a common fastener. They play an important role in connecting parts to ensure the stability and reliability of the connection. This article will explore the definition, function and application of spring washers.

Definition of spring washers

A spring washer is an elastic annular washer, usually made of metal material. It is designed to produce elastic deformation when subjected to force, thereby providing additional tightening force.

Function of spring washers

The main functions of spring washers include:

1. Prevent loosening: Prevent bolts and nuts from loosening under vibration or load changes by providing continuous pressure.

2. Distribute load: Evenly distribute the load applied to the connection and reduce local stress concentration.

3. Absorb shock: When subjected to shock or vibration, spring washers can absorb part of the energy and protect the connection from damage.

Application of spring washers

Spring washers are widely used in various types of mechanical equipment, automobiles, aerospace and construction industries. They ensure the safety and stability of connections in these fields, especially in high vibration or high load environments.

Conclusion

As an important fastener, spring washers have multiple functions such as preventing loosening, dispersing loads and absorbing shocks. Understanding their working principles and application scenarios is of great significance for engineers and manufacturers when designing and selecting fasteners.
