The Galaxie is a new
gearbox type from world-leading German manufacturer Wittenstein, which
developed the product after subjecting drive concepts to a fundamental
The innovative drive
system has not only proved itself to be ‘superior on principle’ in numerous
industrial applications, but has also received scientific acclaim as an
independent gearbox generation.
The compact Galaxie
drive systems and gearboxes achieve previously inconceivable performance data thanks
to their unique kinematics, which enable virtually full surface contact during
power transmission. Performance characteristics of these drive systems include
extremely high torque density, torsional rigidity, smooth running, positioning
accuracy and completely backlash-free operation.
The almost full
surface contact during power transmission lies at the core of the new Galaxie
drive system. This gives a tooth contact surface that is 6.5 times larger
compared to conventional involute teeth with typical linear contact. 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.
portfolio with four variants and fives sizes is now even more versatile with a
new size available: the new Galaxie D drive system in size
085 is designed for use in axes with very high compactness and precision
requirements. It also particularly targets applications where high torsional
rigidity and freedom from backlash are called for rather than torque.
Even the compact
version of this Galaxie drive system is superior to a strain wave gearbox by
delivering three times better torsional rigidity, and one-and-a-half-times the
maximum output speed.
