Wed 13th Nov 2019 - Wittenstein Galaxie - Superior on principle

Wittenstein - Galaxie

Fundamentally new overall concept

When Wittenstein developed the Galaxie®, they took it upon themselves to subject drive concepts to a fundamental reassessment. The result: a brand new type of gearbox. Its unique kinematics enable virtually full surface contact during power transmission. This means that the compact Galaxie® Drive Systems and gearboxes with hollow shaft achieve previously inconceivable performance. These include extremely high torque density, torsional rigidity, smooth running, positioning accuracy and completely backlash-free operation.

From Linear to Surface Contact

wittenstein_galaxieThe innovative core of the new Galaxie® Drive System is the virtually full surface contact during power transmission. This achieves a tooth contact surface that is six and a half times larger compared to conventional involute teeth with typical linear contact. The resulting kinematics are fundamentally new: the gearbox is the only one of its kind in the world to guide a large number of individual teeth along an internal ring gear. The toothing is shaped as a logarithmic spiral, which allows the teeth to grip into the internal ring gear over a large surface.

Next Technology Drive

The Galaxie® Drive System achieves a previously unattainable performance level: the gearbox boasts zero backlash - even at the zero crossing - while retaining full stiffness. The teeth follow a logarithmic spiral which ensures optimal synchronisation accuracy. The system's performance features are all significantly better than those of traditional hollow-shaft drives with the same outer diameter.

The Galaxie® Drive System sets a new benchmark for extreme compactness and very high dynamic precision with alternating loads. It creates totally new productivity opportunities for high performance engineering. Engineers and designers now have the opportunity to make real developmental leaps. The Galaxie is available in four variants and five sizes.
