wittenstein0218Wittenstein presents further developments of its "Galaxie" drive system, including a new size for axes with high requirements for compactness and precision with small to medium torques, an ultra-flat design and a gear version with or without hypoid pre-stage for space-saving machine integration. Practical exhibition models show these as well as the use and advantages of the gears in machine tools, milling heads and robot welding guns.

Since its launch at the Hannover Messe 2015 and winning the Hermes Award, the propulsion system has achieved the scientific status of an independent type of transmission. As a result, it will soon be included in a standard work of machine tool building.

There are five different sizes and a new design. These include the compact version Galaxie D in size 085 for use in smaller milling heads and handling axes with special requirements in terms of torsional rigidity and freedom from play, the ultra-flat Galaxie DF in sizes 110 and 135, which saves up to 30% in length, and the Galaxie GH gearbox variant with one optional angle preamp. The gearbox can be easily integrated into existing machine concepts via flexible encoder interfaces.

Using a sensor-equipped galaxy drive system, the transfer of operating data to an IoT cloud is demonstrated for the first time. In the future, data can be retrieved over the entire life cycle of the drive, regardless of the controller, anywhere and via all terminals.
