Helical Disk Springs
With our helical disk spring, Roehrs can offer its customers a proven and tested machine component, which is used when high spring forces are required within small installation spaces as well as a high operating lifetime of the spring. The uninterrupted grain structure of the raw material leads to an increased durability and reduces the risk of breakage of the coiled spring. This kind of construction also makes it possible to realize various different spring characteristics. The load increase is proportional to the deflection since there appears only bending stress in the strip spring steel.
The essential advantages at a glance:
- Single component design, no breakup into individual components
- Simple and cost-saving assembly and maintenance
- Extremely high spring load at a minimum outer diameter and a low hysteresis
- No erroneous diagram results caused by incorrect layering or grease influence
- High durability due to the use of strip steel with uninterrupted grain structure
- High operational safety due to stable spring loads even in case of breakage (no loss of deflection)
- Spring characteristics are designed according to customers’ requirements
- No friction at mandrel or sleeve due to the fact that the stiffness of the spring allows to dispense with any guidance
- High resistance to negative environmental conditions and extreme temperature variations
- Economical producibility for all applications, also in small quantities
