Belleville washers go by many names, including conical spring washers, disc springs, and spring washers. Their unique design allows them to fit into situations where other types of springs are unsuitable. Belleville washers are used in various industrial settings, ranging from aerospace and automotive applications to heavy machinery and mining equipment. In this blog, we will discuss the different types of Belleville washers and their uses.
What are Belleville Washers?
Belleville washers, also known as conical or disc springs, are a type of mechanical fastener commonly used in engineering and manufacturing. They consist of a cone-shaped metal disc with a small hole in the center and are designed to exert axial pressure when compressed.
The unique shape of Belleville washers allows them to provide constant force over a wide range of deflection, making them ideal for applications where tension needs to be maintained despite changes in temperature or load. This makes them particularly useful in the automotive, aerospace, and construction industries.
One key advantage of Belleville washers is their ability to distribute load evenly across the surface area they come into contact with. This prevents localized stress concentrations leading to failure or fatigue cracks in traditional bolts and nuts. Moreover, due to their compact design, they require less space compared to other types of fasteners.
Types of Belleville Washers and Their Uses
Types of Belleville Washers
Belleville washers come in various designs that cater to different types of loads. Some of the available types of Belleville washers include flat washers, beveled washers, serrated washers, and wave washers. Choosing the appropriate Belleville washer depends on the load, space, and the specific application.
Uses of Belleville Washers
Belleville washers are deployed across different industries, and their applications range from providing low-pressure to heavy-duty environments. Some notable uses of Belleville washers include bolt preloading, vibration damping, load distribution, and shock absorption. Aerospace and automotive industries rely on Belleville washers to maintain pressure in hydraulic and control systems. In the mining industry, Belleville washers are used in the drilling process. They help to maintain the pressure required to drive the drill bit into the rock formation. Sports equipment, such as the drive assembly of a disc golf basket, also utilizes Belleville washers.
Advantages of Belleville Washers
Belleville washers possess a range of benefits that have made them more popular in various industrial settings. Some benefits of Belleville washers include exceptional load capacity, shock absorption, resistance to fatigue, corrosion resistance, and a compact design. They have been shown to provide a better balance between space and force than other designs like helical springs and coil springs.
Material Types for Belleville Washers
Belleville washers have been designed from various materials, including stainless steel, beryllium copper, nickel alloy, and other metallic materials. However, the choice of material will depend on the specific application’s requirements. For instance, marine applications benefit from stainless steel Belleville washers that do not corrode. The resistance to saltwater corrosion is particularly important in seawater desalination plants.
Belleville washers play a crucial role across various industries. Their unique design makes them highly versatile, and their ability to handle and distribute high loads in compact spaces makes them ideal for several industrial applications. Consider Belleville washers if you are looking for a washer that offers reliable performance in challenging applications. When selecting the right Belleville washer, consider the available types, uses, advantages, and material options to select the most appropriate one for your application.
