Application
The ZF-DUOPLAN two-speed gearbox is mainly
used in machine tool drives.
By way of example, the gearbox can be used in
turning machines (horizontal B5, B5 ± 20°
swiveled) or machining centers (vertical V1)
thanks to its variable installation position. The
gearbox is also suitable for use in many systems
in which torque increase or speed reduction is
required.
The gearboxes have coaxial output and are
suitable for the high speeds generated in machine
tool construction. Use with an STW (spur gear
stage) gearbox gives rise to an axle offset, with
the output spur gear being fixed to the machine
spindle with clamping elements. In this case the
machine spindle can be designed as a hollow
shaft.
The 2K2100 variant with input flange ensures a
short installation length thanks to the parallel
arrangement of the gearbox and motor.
