During a press conference held earlier today (Wednesday, September 12) at the Deutsches Museum in Munich, the jury for the Deutscher Zukunftspreis 2018 announced the three finalists for this year’s award. Galaxie inventors Dr. Manfred Wittenstein (Chairman of the Supervisory Board) and Thomas Bayer (Manager Innovation Lab) attended the ceremony and were officially recognized as part of the Deutscher Zukunftspreis “Circle of Excellence”.
The new gearbox class has already won two prestigious awards: the Hermes Award in 2015 and the Innovation Award of the German Economy in 2016.
Dr. Wittenstein was visibly proud of the honor, and noted “Germany’s prosperity is built on its engineering skills. The engineering industry is our country’s core competency and the biggest industrial employer. It is vital that this marketability be preserved for the future. We believe that our invention makes a significant and valuable contribution here.”
Originally unveiled at the Hannover Messe in 2015, the Galaxie® Drive System is based on a novel, scientifically proven gearbox class. Galaxie® meets the two requirements of selection for the final round of the Deutscher Zukunftspreis 2018: the award is a tribute to outstanding scientific and technological innovations, and also has the potential to create sustainable jobs.
A completely new gearbox concept
The principle of the innovative Galaxie® gearbox is founded on several pillars: forces and torques are transmitted not by rigid gear wheels but by separate teeth which can be moved independently of one another. Rather than rolling against each other, these teeth slide to and fro in a ring gear. Furthermore, a very large number of teeth engage with one another at any given time, leading to full-surface contact because they are designed as a logarithmic spiral. This concept inspired the nominated team of inventors – Thomas Bayer and Dr. Manfred Wittenstein – to develop a completely new gearbox class which was radically different from anything that had gone before. “We weren’t happy with the state of the art at the time. Although we could probably have improved certain aspects, we were convinced that there must be another way,” said Dr. Wittenstein when asked to describe what motivated them to tread totally new paths with Galaxie®.
New opportunities for high performance engineering
Mechatronic drive systems like Galaxie® are employed in all kinds of automated production machinery. From food and packaging through medical devices, vehicles and wind turbines to robots or machine tools – almost all daily commodities are manufactured with the help of motor-gearbox units or make use of similar drive systems.
Owing to its novel concept, the Galaxie® gearbox now nominated for the Deutscher Zukunftspreis is superior in all key disciplines, often several times over. This innovation simultaneously requires less material, consumes fewer resources and eases the burden on the environment. It is now up to engineers and designers to completely rethink existing machine concepts and realize genuine developmental leaps, as illustrated by several practical examples: much faster machining operations on lathes, for instance, and a far longer service life for the tools. Unwanted vibration of spline rolling machines has been reduced to a minimum and the machining time is now appreciably shorter. In another application, a new five-axis milling machine was developed with double the usual removal rate. The potential with respect to untapped markets, Industry 4.0 and new materials is huge in WITTENSTEIN’s view in the medium to long term.
Deutscher Zukunftspreis 2018
The Federal President’s Award for Innovation in Science and Technology was instituted and presented for the first time in 1997; the intention is to encourage world-class scientific achievements that are simultaneously marketable and a source of employment. The Deutscher Zukunftspreis is not an award that is applied for, in other words projects must be nominated by one of the institutions entitled to propose worthy candidates. Once a year, a jury comprised of 10 independent experts from academia and industry then selects three teams for the final round.
