AUTOMOTIVE INDUSTRY FASTENERS Conical or Belleville Washers A Belleville washer, also known as a conical spring washer, is a type of non-flat washer. It has a slight cone shape which gives the washer a spring like characteristic. Belleville washers are typically used as springs, or to apply a pre-load or flexible quality to a bolted joint. In certain applications with low dynamic loads, these washers may be used as locking devices. Belleville washers are seen on Formula One cars, as they provide extremely thorough tuning ability. Another example where they aid in locking is a joint that experiences a large amount of thermal expansion and contraction. They will supply the required pre-load, but the bolt may require an additional locking mechanism, such as Loctite, that would fail without the Belleville. Multiple Belleville washers may be stacked to modify the spring constant or amount of deflection. Stacking in the same direction will add the spring constant in parallel, creating a stiffer joint (with the same deflection). Stacking in an alternating direction is the same as adding springs in series, resulting in a lower sprint constant and great deflection. Mixing and matching directions allow a specific spring constant and deflection capacity to be designed. Example: 1 Spring is considered to be 1 in Parallel, 1 in Series.
