The ZASR series is comprised of two-axis rotary tilt tables driven by preloaded gear wheels. Spur gears or bevel wheel sets are used. The installation space and the horizontal or vertical arrangement of the spindle determine the selection. As the gear wheels are electronically tensioned against one another, they operate without backlash. The gears are primarily used by the trunnion axes. The table axes are equipped with direct drives.

Drive type
Pinion drives
Peiseler offers subdevices with preloaded gear sets with spur or bevel gearing. The available space determines the design; usually a multi-stage solution of one of the two alternatives. Compared to the worm gears, gear drives are more complex due to the multi-stage design. Elimination of backlash is achieved by mechanically or electronically tensioning two drive trains. The high torques, speeds and duty cycles are advantageous. Based on their characteristics, gear drives are classified between worm gears and direct drives.
The benefits for you
No cooling required
Better dynamics than worm gears, higher torque density than direct drives
Combines the technical advantages of worm gears and torque motors
Ability to adjust control stability of drive train
Backlash-free, so suitable for simultaneous machining
