Volute Spring | About Product | BU GIL SPRING CO., LTD.

Sharp load increase due to displacement

For Volute Spring, the load increase almost linearly in conjunction with deformation when axial load works downward and sequentially contact the seat from the bottom plate with larger diameter. This plate does not work as a spring after the contact of seat, so the load tends to increase sharply due the displacement above a specic lead.
Vibration Damping Eect

- It prevents the spring from excessive load working on spring.

- It is used for the part on which large load works in relatively small spaces.

- It dampens the vibration due to friction between plates.
Less Fatigue Life

The stress of Volute Springs is mainly caused by the torsion of plate. The stress due to the curvature of plate is taken into consideration. Thus it, in fact, has the stress distribution that combines the above factors, reducing fatigue life.

Shock Absorbing Device for Large Industrial Facilities
- It absorbs large energy in space-volume ratio.
- It damps vibrations using the friction between plates.
- It is used as the suspension systems for railroads or heavy vehicles, and the shock absorbing devices for large industrial facilities.
