Changes in the fatigue strength of springs due to dimensional effects and the influence of internal defects in the material.

Changes in the fatigue strength of springs due to dimensional effects and the influence of internal defects in the material.

[Reproduction of Private Spring Preparatory School Lecture 21] Yielding and fatigue destruction are related not only to the maximum surface stress but also to the stress at a certain depth from the surface!

Now, let's talk about the effect of dimensions. There are various types of leaf springs, both thick and thin, and coil springs with materials of different diameters, both thick and thin. In this way, when it comes to plates, the thickness changes, and for round bars, the diameter changes. Does the fatigue strength remain the same? In fact, it does change. This is referred to as the dimensional effect in fatigue. When testing thick and thin specimens in fatigue tests, excluding tensile and compressive fatigue limits, generally, thinner specimens show a greater fatigue limit in bending and torsion. Since most springs are used in bending or torsion, let's keep this relationship in mind as well. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*

Causes of quenching distortion and methods for suppression, effective measures using press quenching methods.

Causes of quenching distortion and methods for suppression, effective measures using press quenching methods.

[Reproduction of Private Spring Preparatory School Lecture 61] Explanation of quenching distortion! A method of quenching with less distortion is also explained.

Let's study how quenching distortion occurs. Even without special study, you can clearly understand the results just by conducting an experiment. A flat spring plate of appropriate length is ideal for the experiment. Heat this spring plate to the quenching temperature and cool it from only one side of the plate. For example, if you cool only the bottom side, it will ultimately deform so that the bottom side becomes convex. Let's look at the diagram. First, since the bottom side of the plate is sprayed with water, it will naturally shrink due to thermal contraction. In other words, since the bottom side shrinks, the plate will deform to be convex upwards. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.

Gold-plated bellows contact spring (Servometer)

Gold-plated bellows contact spring (Servometer)

A reliable gold contact utilizing the flexible expansion and contraction of an electroplated bellows!

The precision gold-plated bellows contact springs from Servometer Inc. (USA) demonstrate high reliability in areas where issues arise with the repeatability of springs and stress due to tolerances, vibrations, and thermal expansion. The flexibility of the springs minimizes shocks and vibrations in dynamic applications while maintaining contact. The spring constant is very low, allowing for production at a required stress of 44.49g per mm. This enables designs for contacts that use delicate components and materials. The product is made with electroless nickel and is gold-plated to enhance conductivity. Most end caps are designed to fit into pins or pockets, allowing for connections to other components without soldering. **Features** - Very low self-inductance - Very low DC resistance - Very low insertion loss - High repeatability of the spring - No need for large forces to maintain contact at two points - Can be used for electrostatic discharge (ESD) protection as needed
