Belleville spring: purpose and technical features

The production of disc springs provides for their production in a wide range for various purposes. For example, to use them in corrosive 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 function. It has endurance, and its products are operated in a wide temperature range: from -60 ° C to +120 ° C.

Appointment

The main task that the Belleville spring must perform is to withstand very heavy loads, but at the same time to ensure minimal deformation. This is facilitated by, first, the disk form. Secondly, ensuring the principle of elastic deformation. Belleville spring consists of individual segments with a large area, so they are good at absorbing loads and have the ability to accumulate energy. Its stem has a cone-shaped ring, which is designed to resist deforming forces. Being subjected to a heavy load, this system balances and tends to balance.

For various functional needs, designers have developed a number of parameters that can be matched to a disc spring. Therefore, it is used by machine builders. Actively involved in such details in the oil and gas industry. Energy and instrumentation also need plate springs. They are also used in mining enterprises .

Ways to Build

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

Quality requirements

The cause for breakage of the spring may be destruction caused by excessive deformation. In cars, this largely depends on the terrible road conditions. In any case, replacing the Belleville spring ("Priora" is a car or another) often happens for this reason.

They are not allowed to be used if they have cracks, corrosion marks on the surface, electrical burns or chips. Do not install discs that have strong roughness caused by machining metals. To reduce the effect of friction, all elements entering into the disk-type spring must be lubricated. The products must be marked. It indicates all the necessary technical characteristics.
