Wittenstein Galaxie drive systems and gearboxes

In developing the Galaxie, Wittenstein has reassessed drive concepts to produce what the company says is a new type of backlash-free gear unit. The innovative drive system’s maintenance-free kinematics enable virtually full surface contact during power transmission, meaning that the compact Galaxie drive systems and gearboxes achieve high torque density, torsional rigidity, smooth running and positioning accuracy. This makes them suitable for industries such as machine tool, packaging and food and beverage machines.

The innovative core of the new Galaxie drive system is the almost full surface contact during power transmission. This gives a tooth contact surface which is 6.5 times larger compared to conventional involute teeth with typical linear contact. The gearbox is said to be the only one of its kind in the world to guide a large number of individual teeth along an internal ring gear.
