Belleville spring: purpose and technical features

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

The main task that the Belleville spring must perform is to withstand very strong loads, but at the same time ensure minimal deformation. This is facilitated, firstly, by the disk form. Secondly, ensuring the principle of elastic deformation. A Belleville spring consists of separate segments with a large area, so they are well absorbed by the load and tend to accumulate energy. At its core is a conical ring, which is designed to resist deforming forces. Being heavily loaded, this system balances and strives for balance.

For various functional needs, designers have developed many parameters that a Belleville spring can correspond to. Therefore, it is used by machine builders. Actively use such parts in the oil and gas industry. Energy and instrumentation also require plate springs. They are also used at mining enterprises .

Assembly methods

Belleville springs production

Depending on the shape of the disk, various types of assembly of products are used. This greatly expands the classification of springs. For example, if a cup spring is made in a sequential assembly, an effect is created in which the amplitude of the deflection increases. Therefore, the more disks will be included in the unit, the more energetically its depreciation will be. But if you change the way the plates are stacked in a parallel arrangement, then their deflection when exposed to 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 sequential and parallel placement of disks in one unit allow you to get 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

Prior Belleville Spring Replacement

Damage caused by excessive deformation may cause a spring to break. In cars, this is heavily dependent on terrible road conditions. In any case, replacing a Belleville spring (โ€œPrioraโ€ is a car or another) most often happens for this reason.

They are not allowed to operate if they have cracks, traces of corrosion on the surface, electric burns or chips. Do not install discs with strong roughness caused by metal machining. To reduce the effect of friction, all elements included in the disk-type spring should be lubricated. Products must be labeled. She indicates all the necessary technical specifications.
