In metal springs, a loss of force occurs under permanent tension and higher temperatures, which is called relaxation. This loss of force increases with increasing temperature and load duration. This loss of force is given as a percentage of the
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
Whether in cooling systems, in space or other low temperature applications. Metal springs often have to withstand temperatures of up to – 200 degrees. Despite rising tensile strenght low temperatures have an unfavorable effect on the material, as the toughness
To absorb forces and movements are sometimes also Spring systems used. Due to the different arrangement of Compression springs A wide variety of force properties can be generated. Simple spring systems are: Compression springs parallel connection The springs are arranged
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.
