Galaxie® Product Line Expanded with New Sizes, Ultra-Flat Design and Hypoid Version

New products will be featured in active demos at Hannover Messe April 23-27, 2018

WITTENSTEIN SE, a leading global manufacturer of motion control products, servo systems and mechatronic systems, announced it is expanding its renowned Galaxie® system product line to include more sizes, a hypoid version and a new ultra-flat version. The new products will be launched at the upcoming Hannover Messe Fair in Germany this April 23-27. 2018.

The expanded product line includes:  

  • The compact Galaxie® D in size 085 for use in smaller cutting heads or handling axes where special requirements apply regarding torsional rigidity and freedom from backlash.
  • The new ultraflat Galaxie® DF in sizes 110 and 135, which saves up to 30 percent of the normal installation length.
  • The Galaxie® GH with its optional rightangle input stage.

Several moving demos will demonstrate how the flexible encoder interfaces allow Galaxie® to be easily integrated into existing machine concepts. These demos will show the drive system in action, highlighting Galaxie® products’ technological superiority in machine tools, cutting heads and robot welding guns, to name but a few.

Drive system transmits operating data
For the first time, WITTENSTEIN will show how operating data can be transmitted to an IoT cloud using a Galaxie® Drive System equipped with sensors. This data can be accessed anywhere and on any device throughout the drive lifecycle, regardless of the control system.

Disruptive innovation – a new way of thinking in high performance engineering
The inherent superiority of the Galaxie® principle is scientifically proven. The decisive features here are the dynamic teeth instead of a rigid gear ring, the tangential and hydrodynamic tooth contact over the full surface when loaded and the new type of bearing with a segmented outer race ring. All of this adds up to a novel design principle, with the result that Galaxie® is clearly superior to other, established principles in all key technical disciplines compared to the market standard. In short, Galaxie® is a disruptive innovation which is increasingly causing existing design strategies to be overturned and rebuilt.

Logarithmic spiral defines Galaxie® as an independent gearbox generation
Galaxie® Drive System’s status as a new gearbox generation is based on the scientific reasoning of the logarithmic spiral -  the mathematical function introduced by WITTENSTEIN. The gear toothing takes the form of an input polygon, around which the individual teeth are grouped, leading to full-surface contact and mathematically precise synchronous running. Both the theoretical functionality of Galaxie® and its technical performance features and benefits are meanwhile generally accepted among scientists – especially since the logarithmic spiral is also recognized in the “mathematics” of nature in effectiveness, for instance in a snail’s shell.

As the 2015 winner of the prestigious Hermes Award at the Hannover Messe, Galaxie’s innovative drive system has not only showed itself to be “superior on principle” in numerous industrial applications, frequently making the impossible possible – it has also received scientific acclaim as an independent gearbox generation. It is even set to be featured in a standard reference work on machine tools in the near future. A staunch community of enthusiasts, who have referred to Galaxie® as a “milestone in engineering” in various publications and presentations, has also emerged among businesses and industry associations such as the German Research Association for Power Transmission (FVA) or the German Engineering Federation (VDMA).
