Galaxie® Gearboxes and Drive Systems - WITTENSTEIN North America

WITTENSTEIN galaxie

With the maintenance-free Galaxie^®, WITTENSTEIN has reenvisioned the concept of mechanical gearing. The result: a fundamentally new type of backlash-free gear unit. The maintenance-free, unique kinematics maintains almost complete surface contact of every tooth during power transmission. As a result, the backlash-free Galaxie^® drive systems and gearboxes with hollow shafts achieve previously unimaginable performance data. These include extreme torque density, torsional rigidity, low synchronization error, high positioning accuracy and absolute freedom from backlash. Compared to involute or cycloid gears, the Galaxie technology enables maintenance-free backlash over its entire service life.

BACKLASH-FREE GALAXIE^®

The Galaxie^® is a hollow shaft drive with lifelong zero backlash, maintenance-free use and maximum precision, based on three radically new ideas...

A disruptive innovation

In contrast to commercially available cycloid or involute gears, the disruptive Galaxie technology enables absolute zero backlash over the entire service life.

The scientific proof that Galaxie^® is an independent gearbox class and its successful use in high performance engineering are rapidly establishing our invention as a firm fixture in research and teaching. We asked three professors to give us their expert opinion on the new gearbox class. There was unanimous agreement that Galaxie^® is a revolutionary innovation.
