Friction Springs
 

Description Of Function
The primary function of a friction spring is the damping / absorbing of introduced energy. A friction spring consists of closed outer and inner rings which intermesh with their conical surfaces. As a result of the energy introduced axially, the outer and inner rings on the conical surfaces are shifted apart from each other so that the spring column is shortened. This has the effect that the outer rings stretch and the inner rings reduce in diameter.

As a result of the friction arising on the conical surfaces, the introduced energy is absorbed and converted into heat which is to be removed. Resonance effects are suppressed completely.
