Miniaturized Galaxie®

Miniaturized Galaxie® gearbox

The miniaturized Galaxie® gearbox combines maximum precision with a compact design. The innovative kinematics result in almost complete surface contact during power transmission – for maximum torque density and rigidity. The large hollow shaft offers design freedom, while the permanent zero backlash and high overload capacity ensure reliable performance. Ideal for machine and robotics applications where compactness and maximum accuracy are required.

1) Torsional rigidity:
Ct21: Average increase of the hysteresis in a range of 50 to 100% of Tmax
K1: Average increase of the hysteresis in a range below 10 Nm for SAG090 and below 15 Nm for SAG110
K2: Average hysteresis gradient in the range between 10 Nm and 25 Nm for SAG090 and between 15 and 50 Nm for SAG110
K3: Average increase of the hysteresis in a range over 25 Nm for SAG090 and over 50 Nm for SAG110

The unit Nm/arcmin can be converted into 104 Nm/rad using a factor of 0.3438.
