Elastomeric Materials – An Overview

By Simon Graf on Jan 04, 2017

Elastomers are polymeric materials which have the property of high elasticity. By virtue of this elasticity in combination with their damping capability, elastomers are the preferred material for use as transmission elements in elastic or highly elastic couplings. [1]

Mechanical Properties of Elastomers

By Simon Graf on Nov 30, 2016

One of the distinguishing properties of elastomers is their high elasticity. The main characteristics of elastomers present themselves, in particular when comparing them to steel. Below we would like to elaborate on the main properties of elastomers in more detail. Figure 1 shows the main characteristics of elastomers. They are able to combine spring properties as well as damping ability in one component.

Dynamical Torsional Etiffness: Some Couplings Need Finer Tuning

By Simon Graf on Aug 24, 2016

The coupling is normally the softest element in the drive line, literally – but by no means the weakest link of the chain. Its configuration plays a decisive role for the functional capability of the driving and driven machine and for the reliability and lifetime of the entire drive system. The optimum adjustment of the coupling to the connected machine units is especially important in all cases where failures and breakdowns are not allowed to occur.

Stiffness and Damping: This is what Engineers have to Consider when Tuning a Coupling

By Simon Graf on Jul 20, 2016

Stiffness describes the ability of a body to resist elastic deformation. The transmission of power would not be possible without stiffness. However, there are events which should not be transmitted, such as torque peaks and shock loads. In order for a system to withstand such loads, it is damped. Engineers are confronted with the challenge to tune stiffness and damping in a vibratory system in such a way that reliable operation, essentially free of load peaks, is ensured.
