Detailed Product Description

The inner and the outer wheel having a cone-shaped section do compression and extension each and simultaneously, the contact part of the inner and the outer wheel does frictional works. The ring spring uses elasticity and frictional force of the inner and the outer wheel. The load-displacement relationship of the ring spring shows a clear hysteresis because energy loss becomes big due to friction of the inner and the outer wheel. This hysteresis phenomenon is different according to the number and the shape of the contact part so a change in the spring constant of the ring spring can be obtained by increasing/decreasing the number of rings and by changing the shape.
