Transmission of rotational movements – Basics of couplings

When shafts and axes are coupled in a machine, there is always a misalignment between the centre points of the shafts. The coupling compensates for this alignment error by the elasticity of the component or mechanical element during rotation or power transmission. Whether you are an experienced engineer or just diving into the world of mechanical engineering, this article gives you a comprehensive insight into the basics of couplings.

Friction and friction coefficient determination of friction values of materials

The friction coefficient is a physical variable derived from the field of tribology for the friction between two objects. The friction coefficient sets the force that occurs during friction (frictional force) in relation to the force with which the objects are pressed together (pressing force). The friction coefficient is thus an important parameter when examining material wear and sliding properties. This article explains the basics of the friction coefficient, its measurement methods and its applications in technology.

Selecting V-belts and V-belt pulleys

V-belts and V-belt pulleys are basic components of belt drives and are used in many mechanical systems in the industrial sector. Belt drives transfer rotary motion, torque, and power from a drive element to a driven element. In contrast to toothed belt drives that transfer power with an interlocking mechanism, belt drives work in a friction-locking manner. It is characteristic of belt drives that they ensure efficient friction-based power transfer and a longer service life while simultaneously providing a simple bearing arrangement.
