ATU

Table with worm gear drive

The ATU table series is equipped with a vertical rotation axis and a horizontal face plate for machining larger workpieces and for heavy-duty cutting applications. Driven by a worm gear set as standard, we can also incorporate a belt-driven adapter drive on request. The ATU series is fitted with YRT bearings, with the maximum bearing diameter forming the basis for the design. To save on installation height, the housing is flat. The cast housing is designed with thick walls and strong ribs. We would be happy to provide our design for large face plate through-hole requirements if required.

Drive type

Worm gear drives

Peiseler uses three-piece worm gears, a well-known design developed by Ott. These gears consist of a worm wheel and a two-piece worm, the shank worm and hollow worm. During assembly, we adjust the gear so it is backlash-free. Readjusting the worm during its service life is simple with a commercially available mounting tool. The design advantages are a compact gear ratio, high mechanical precision and the control's excellent regulatory quality. Heat limits the duty cycle.

The benefits for you

  • Simple commissioning/easy installation

  • Easily adjustable worm gear

  • Maximum drive moment and low backlash

  • Self-braking (safety feature)

  • Cost-effective solution for positioning applications
