Motor-driven rotary table AWR

horizontalfor machining

The AWR trunnion table series is driven by preloaded gears (double pinion drive). Both spur gear and bevel gear sets are used, whereby the available installation space plays an important role in the selection. The electrical pretension of the gears always ensures backlash-free operation. Compared to worm gearboxes, the AWR trunnion table drives have a higher duty cycle and are therefore more dynamic and capable of simultaneous operation. • Counter bearings and trunnion devices • Steady rests • Roller blocks • Substructures and base plates • Rotary manifolds • Absolute direct encoders 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.
