Double spiral disc spring

Helical disk springs

With our patented helical disk spring, we can offer our customers a proven and tested machine component which in many cases replaces the common multi-layer disc spring assembly. The helical disc spring consists of 2 identical flat wire compression springs screwed into one another to achieve a cross-section similar to that of disc springs. The uninterrupted grain structure of the raw material leads to an increased durability and reduces the risk of breakage of the coiled spring.

In principle, the characteristics of any inversely layered disc spring assembly can be

realized with a helical disc spring design. The load increase is proportional to the deflection since there appears only bending stress in the strip spring steel. It is also possible to apply a pitch during the coiling process of the helical disc spring, allowing it to initially display the characteristic of a compression spring and to work with the high loads of a disc spring assembly at the first contact of its coils.

The essential advantages at a glance:

1.Single component design, avoiding mismatch and friction of individual discs;

2.No erroneous diagram results caused by incorrect layering or grease influence；

3.Uninterrupted grain structure reduce the risk of breakage;

4.Stable spring loads even in case of breakage (no loss of deflection)；

5.No friction at mandrel or sleeve due to the fact that the stiffness of the spring allows to dispense with any guidance;

6.Simple and cost-saving assembly and maintenance；

7.Tailor designed according to customer’s requirement；

8.High resistance to negative environmental conditions and extreme
