Review: DGEB Conference 2017, Weimar

By Lars Jahnel on Oct 11, 2017

This year, the 15th D-A-CH Conference, which is organized by the Societies of Earthquake Engineering and Structural Dynamics in Germany (DGEB), Austria (OGE) and Switzerland (SGEB) took place on September 21 and 22. September.  

This gathering of experts is conducted biennially and serves both as the exchange of knowledge between seismologists and engineers and the presentation of current scientific findings and experience gained from field applications. In addition, companies operating in the fields of earthquake engineering and structural dynamics as well as manufactures of earthquake protection systems had the opportunity to present their application solutions in the foyer of the Bauhaus university.

Economical Hollow Shaft Connections

By Ringfeder News on Apr 29, 2016

Many power transmission applications, including gearboxes, require a reliable connection between a solid and hollow shaft. This type of connection, however, only works well if the solid shaft outside diameter and hollow shaft inside diameter have been properly machined to exact dimensional tolerances and finishes. These precision machining factors drive up costs and limit the design freedom of solid-to-hollow shaft connections.
