Hardness and hardness testing in comparison

A wide variety of raw materials and ancillary materials are used in industrial applications. Comprehensive knowledge of their material properties is an absolute prerequisite for using these raw materials for a defined application in technical environments. Hardness tests are a way to determine basic material properties such as hardness/ductility and strength of a material, such as steel. Hardness plays a critical role in the characterization and quality control of materials. The hardness of a steel provides information about its mechanical properties, wear resistance and suitability for specific applications. In this context, various hardness testing methods and scales have been developed to accurately determine and classify the hardness of steel. This article provides an overview of common hardness test methods, an overview of some of the heat treatment options for steel materials, the resulting Vickers hardness levels and their possible applications.

Mechanical power transmission: Movement types, timing belts and gears

There is the uniform movement wherein a body moves at the same speed at all times, and is neither accelerated nor decelerated.

Non-uniform movement occurs when the speed or direction of a body changes during the movement process, which can lead to acceleration or deceleration. There are two cases: uniform acceleration and non-uniform acceleration.

Properties of damping materials and their uses

Mechanical engineers rely on damping materials wherever unwanted vibrations, oscillations, shocks or noises occur. If these vibrations remain uncontrolled, they can lead to precision losses, premature material wear, and even machine destruction. As a result, damping materials not only increase the service life and performance of machines, but also often protect them against damage. In addition to foams, felt and rubber, specialty plastics are also used for producing damping materials. This blog article provides an overview of the various damping materials and how to use them.

Ball bearings – Load distribution for rolling bearings

Ball bearings and other rolling bearings are installed in numerous machines. The installed bearings transfer the radial or axial forces that occur to the machine housing and thus permit the use of various moving components. The forces that occur and the resulting load in the bearing must already be determined during the design process. The load distribution in the bearing and the matching contact point geometry is crucial for the expected service life, function and efficiency of the bearing. In this article, we will look at the load exerted on a rolling bearing and how contact surface geometry affects load distribution in the rolling bearing.
