The production of Belleville springs provides for their production in a wide range for various purposes. For example, for their use in aggressive environments, materials that do not cause corrosion are used. For the needs of the automotive industry, they are made of steel, which has a spring-spring purpose. It is distinguished by endurance, and products made from it are used in a wide temperature range: from -60 ^oC to +120 ^oC.

The main task that a Belleville spring must perform is to withstand very high loads, but at the same time ensure minimal deformation. This is facilitated, firstly, by the disk form. Secondly, ensuring the principle of elastic deformation. The disc spring consists of individual segments with a large area, so they perceive loads well and tend to accumulate energy. At its core is a cone-shaped ring, which is designed to resist deforming forces. When subjected to a heavy load, this system balances and tends to balance.

For various functional needs, designers have developedset of parameters that a Belleville spring can match. Therefore, it is used by machine builders. Such details are actively used in the oil and gas industry. Energy and instrumentation also need disc springs. They are also used in the mining industry.

Assembly Methods

Depending on the shape of the disc, different types of product assembly are used. This greatly expands the classification of springs. For example, if a belleville spring is manufactured in a series assembly, then an effect is created in which the deflection amplitude increases. Therefore, the more disks will be included in the block, the more vigorous will be its depreciation. But if you change the method of stacking the plates to a parallel arrangement, then their deflection under the influence of forces will be minimal, and the spring force will depend on the number of disks in it. There is another option - a combined assembly. In this case, both serial and parallel placement of disks in one block allows you to get two effects: a strong deflection of some elements and a slight deflection of others. The number of possible combinations has no limit, and this increases the functionality of the springs.

Quality requirements

The reason for the breakage of the spring may be the destruction caused by excessive deformation. In automobiles, it depends to a large extent on the terrible road conditions. In any case, replacing the belleville spring ("Priora" is a car or another) most oftenhappens for this reason.

They are not approved for use if they have cracks, corrosion on the surface, electrical burns or chips. Discs with strong roughness caused by metal machining should not be installed. To reduce the effect of friction, all elements included in the Belleville spring must be lubricated. Products must be marked. It specifies all the necessary specifications.
