Application and Design
2.1
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) or machining
centers (vertical V1) thanks to its variable installa-
tion 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 suit-
able for the high speeds generated in machine tool
construction.
