Damping Technology

  • High spring work with low weight and volume
  • In Block overload-proof
  • High Attenuation
  • Maintenance-free
  • Force-displacement diagram is independent of the load speed

Friction springs and "RF" are vital safety components must be included in all the technical areas in which sudden forces and kinetic energy, or springs with high force in a relatively small dimensions are required. Friction springs and "RF" are used where large amounts of kinetic energy and steamed absorbed, or a relatively small spring size is required, to high forces to withstand. The areas of application of the friction springs and "RF" are very diverse. Here, overload protection, glass path and energy absorption are mainly offered in three performance aspects, which can also be combined with each other:. Friction springs and "RF" consist of Outer and inner rings, the touch of your cone surfaces with the use of a special lubricant. An axial load on the spring column, the effect of the conical surfaces slide against each other, and each Ring is elastically deformed. This means that The outer ring is stretched and the inner ring is compressed. The resulting spring deviation is calculated from the change in Diameter of the elastic deformation of the ring and the cone angle. Compared to other types of Spring, the Circumferential stress is distributed nearly uniformly over the cross section of the loaded spring element, so that each component is evenly utilized. This is a lighter friction spring "RF in comparison to other similar types of springs". The special characteristics of the friction spring, the strong friction damping of about two-thirds of the introduced energy is.

Use of friction springs

Friction springs and "RF" are of the same type, External and internal rings set up. Due to a change in the number of elements of any travel and so each spring stiffness can be achieved. The Spring end force, however, remains with different element numbers unchanged. It is the travel and the length of the Spring changes.

Offers alternatively, each of the friction springs and "RF" TAS Schäfer also complete industrial buffer of the series "IPA 1", "IPA 2", "IPA 3", and "IPA 4". These consist of individual friction springs which complete Installation shall be supplied in a housing. By default, four different buffer designs are available to the customer for selection. These differ in the execution of the plunger and flanges. Typical areas of application for the buffer are: roller conveyors, crushers, cranes, trolleys, mobile systems, Bumpers, as well as the entire machinery and steel construction.
