What’s the Purpose of Washers?
Washers are tiny and inconspicuous components of most machines, yet they play a significant role in ensuring the smooth operation of equipment. But what exactly are washers, and what purposes do they serve? In this article, we will dive deeper into the functions and types of washers, and learn how critical they are in everyday life.
What are Washers and Why are They Important?
Washers are thin, flat metal or rubber discs with a hole in the center. They are typically placed between two objects to distribute pressure and prevent direct metal-to-metal contact. By providing a cushion, washers help prevent damage to surfaces, reduce vibration, and provide thermal insulation. They also help distribute stress across a wider area, extending the life of the machine or equipment.
Types of Washers.
There are different types of washers available on the market depending on the intended purpose, material, and shape. Here are some of the most common:
1. Flat washers – These are the most basic type of washers and are often used between the head of a bolt or screw and the surface which they are to be anchored.
2. Lock washers – These are designed to prevent nuts and bolts from loosening up due to vibration or shock.
3. Spring washers – These are used to absorb shock and provide pressure to maintain tension, particularly in high torque applications.
4. Wave washers – These are curved in a wave-like pattern to provide flexibility and compensation for weight and thermal expansions.
5. Beveled washers – These are commonly used in construction to help distribute load over a wider surface area.
How Washers Work.
So, how exactly do washers work? Consider a bolt and nut assembly - without a washer, the joint would be unstable due to the amount of pressure being concentrated in small areas. Similarly, when machinery is vibrating, the vibration can cause bolts or other components to loosen, which can create safety hazards or harm the equipment. By sandwiching a washer in the joint, the washer helps distribute the pressure across a broader area, thereby keeping the assembly secured in place, even under continuous vibration.
Washers vs. Spacers.
On occasion, washers tend to be mistaken for spacers, as both have a similar appearance. However, spacers do not have an opening in the center, and their primary purpose is to keep two separate components apart without interfering with their structure. Washers, on the other hand, are designed to distribute stress and reduce the impact of friction, while also adding an extra layer of support.
Conclusion.
Washers may be small in size, but they play a critical role in maintaining the health of various machines and equipment. The right type of washer can have a significant impact on the longevity and performance of certain equipment, which is why choosing the right type is essential.
