The level of the working temperature can significantly influence the function of a metal spring, as the tendency to Relaxation increases with increasing temperature. table : Limit temperatures from Spring materials with minimal relaxation material Maximum working temperature in °
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
Exceeds when the spring is loaded Shear stress the permissible value, a permanent deformation occurs, which manifests itself in the reduction of the unstressed length “L0”. This process is called “setting” in spring technology, which is associated with the properties
Every spring design of a compression spring consists of two stages : 1. The proof of function, with the verification of the dimensions, spring rate, forces, spring travel and vibration behavior. 2. The proof of strength, with the verification of
The pitch “S” of compression springs, also known as the coil pitch, refers to the distance between their individual coils (wire center to wire center) and is calculated and determined using the following formulas. It is measured parallel to the
What is shot peening? Shot peening is a special kind of Surface treatment . In the process, blasting media are accelerated in special systems and hit the surface of the workpieces to be processed, such as Metal springs , steered.
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
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
The modulus of elasticity is a material parameter from materials engineering and defines the slope of the graph in the stress-strain diagram. This characteristic describes the relationship between tension and strain in the deformation of a solid body in a
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
