Slowing down moving masses in a quick, safe and precise manner: RINGFEDER® Friction Springs are indispensable safety components in all technology and industry sectors where suddenly occurring forces have to be taken up and kinetic energies must be absorbed, or when damping systems are required for enormous forces at relatively small dimensions. They consist of precisely manufactured outer and inner rings which are assembled to complete spring columns according to the individual requirements of the user. These are 100 % tested and loaded several times before delivery, which guarantees absolute functional reliability – whether as proven standard or highly specific custom-made designs.
RINGFEDER® Friction Springs have multitude features in opposite to other damping systems:
If a RINGFEDER® Friction Spring consisting of “e“ elements terminates with half rings its untensioned length will be:
The total spring travel can be calculated according to the equal:
When eliminating the pretensioning force the spring work is given by:
The end force does not change with the number of elements.
The buffer types are standard delivered in one of four designs. These buffers are suitable for operation temperatures from -20 °C to +60 °C. Above that, modifications allow an extended temperature range from -73 °C to +200 °C.
