Helical-bevel gearboxes have the major benefit of enabling extremely precise and reproducible positioning movements owing to their high torsional stiffness and low backlash. In connection with three-phase AC and servo motors, they form an extremely compact unit.

They are available in a 3- and 4-stage design with a torque of up to 11,639 Nm and a ratio of up to i=1936.

Advantages:
  • 3-stage and 4-stage gearboxes
  • Hollow shaft with keyway or shrink disc
  • Solid shaft with keyway
  • Foot or flange mounting
  • Torque plate, including rubber buffer
Can be combined with the following motors:
  • With three-phase AC motors in line with the ErP Directive in the power range from 0.12 to 45 kW
  • With servo motors in the power range from 0.25 to 20.3 kW
  • Drive Package versions in conjunction with the decentralised Inverter Drives 8400 motec cover a power range of up to 7.5 kW
