The world of manufacturing and machinery can indeed be complex. From unique processes to specialty designs and applications, manufactured components are difficult to understand and work with. One of these components is the Belleville spring, which requires an expanded vocabulary to understand how it works. Read on to learn more about what Bellevilles are and discover some terms that explain the intricacies of these components. What Are Belleville Springs? Belleville springs are a variety of washers with a unique semi-coned shape used in a variety of large duty applications. Bellevilles are designed to act as heavy duty compression springs, capable of handling extreme amounts of weight and pressure. Bellevilles are able to be stacked within a system and are frequently used in large machinery and assist in shock absorption. Belleville-Related Terminology Load—In spring and bolting applications, the load refers to the amount of force, weight and/or pressure exerted on an object. Functions that require a high load level must be able to withstand a great deal of pressure and disturbance. An example of a process requiring high loads is down hole oil drilling. Live-Load—Live-load includes not only the weight and pressure of a given structure but also that weight which is added to it. If something is temporarily added to the weight of machinery, for instance, it is live-loaded and counted in the overall weight of the structure. Deflection—Aside from the load itself, items like springs have a certain threshold that they can reasonably accommodate without giving out. How much a spring is displaced under its load indicates its level of pressure resistance. This resistance may also apply to momentum. Flange Bolting—Flange bolts are distinct because they are combination bolt/washer components. These bolts have ridged skirts below the bolt heads, which are intended to increase the overall strength of the component. A common application of flange bolting is in pipefitting. Bolt Creep—Bolt creep involves the deformation and/or displacement of metal bolts. Bolts are constantly stressed, due to vibration, movement or temperature increases. They also inherently resist the way they’ve been fastened, so the tension applied to them at the outset gradually relaxes. This phenomenon is dangerous because loose bolts allow for leakages within systems. Potential Energy—Every object stores energy relative to its position. The usual position for heavy duty compression springs would be relaxed and without tension applied. In this state, nothing is being done to the spring and therefore no energy is stored. However, when an item is put to work, such as when a spring is pressed down upon, change in position and exerted pressure creates energy, known as potential energy. This energy can then be applied to perform a task (i.e. when the spring is released again). Thermal Expansion—Thermal expansion is the increase in size of an object in terms of length, height or thickness as the object is exposed to heat changes. Belleville springs may function to compensate for expansion and contraction of parts within complex systems, such as in steel mill equipment, which regularly experiences temperature changes. Tensile—Bellevilles are frequently hailed for their tensile strength. This is pulling strength. High tensile strength indicates that an object like a Belleville spring can withstand a great deal of pulling force before it breaks. Bellevilles are constructed to provide heavy duty support, so the stress they can take before deforming is substantial. Cryogenic—The term cryogenic refers to extremely low temperatures. Bellevilles are used in various applications, from high heat to temperatures as low as -330 degrees F. Products are therefore created with cryogenic purposes in mind. Ferromagnetic—Some materials are naturally magnetic, able to act as magnets themselves. These include such metals as iron, cobalt and nickel, the last of which is frequently used in Bellevilles. Ferromagnetism is the strongest form of magnetism, and the only form that humans feel, producing a strong force. Understanding the complex nature of Belleville spring components requires a specialized knowledge set. These components may be used in a variety of industries, from oil drilling to steel production. Given their wide range of use, it is essential to understand Bellevilles and their relevant terminology. The author has an immense knowledge on heavy duty compression springs.
