Always the right compression spring, extension spring and torsion spring – from the quick spring selection in the catalog, to the design and calculation of individual metal springs, to the CAD data generator for standard springs and freely calculated metal
Range of springs made to measure
Compression springs, extension springs and torsion springs are typical C-parts for most companies: They are not the focus of the procurement process, but are used in almost all technical applications. The requirements for the springs are very versatile and individual.
The right metal spring
Selecting the right metal spring for the desired application is not always easy. In many technical books with constructional basics, the subject of springs is treated in a very general way. If you are looking for a standard spring, you
Metal springs for extreme cases
Whether in corrosive liquids, at High temperature applications or at lowest temperatures , with dynamic or static loads, compressive, tensile or bending loads: With the Design of the metal spring in extreme cases there is more to be done than
Goodman Chart
The Goodman diagram enables the representation of the Fatigue strength of coil springs. It can be traced back to the Smith chart. This is used to calculate the fatigue strength of dynamically stressed components where the load is pulsating or
Spring steel wires and their properties
Which spring steel wire is suitable for which application? Spring steel wire compared to other steels has a higher strength and can be up to a certain voltage ( Elastic limit “Rp” ) are deformed. With this property, the spring
Design spring body
Metal springs are used in various designs. In addition to the cylindrical design, which is most commonly used, there is also the conical, barrel-shaped design or for special ones dynamic Compression spring applications the beehive spring. Each design has a
Types of stress extension springs
Description Formula symbol tension springs Before interpreting the extension spring it must be clarified whether the intended type of stress is a static or a dynamic stress acts. No general fatigue strength values can be given for dynamic loads on
Design of metal springs – Part 2 “Calculation
In the first part of this two-part series Gutekunst Federn informed about the basics of spring design. In this second part you will find the concrete calculation data for the design of compression springs, extension springs and torsion springs (torsion
Spring characteristic
The spring characteristic shows how the metal spring behaves at work. It describes the relationship between spring force ( F ) and spring deflection ( s ). Depending on the type of spring or the spring system used, a distinction
