NORD UNICASE worm gear units with increased torque

NORD Drivesystems has increased the maximum torque of its UNICASE worm gear units, achieving an increase in performance of 10–15% without changing the gear units’ outer dimensions. Higher performance can now be achieved without the need for adjusting existing configurations.

As the housing sizes remain unchanged, the worm gear units will still be available as a drop-in solution for maintenance works or repairs. To save costs and installation space, smaller sizes can be selected according to the application, resulting in more constructive freedom in machine and system design.

The dimensions have not changed, but in order to implement higher power ranges, NORD incorporated new worm shafts with larger bearing seats, as well as an additional reinforcement of the worm wheel itself. The current UNICASE worm gear unit series offers a power range from 0.12–15 kW, and torques between 90 and 3000 Nm. NORD says other advantages include smooth and quiet running, high overload capacity and robust design.

The UNICASE worm gear units in cast iron housings are available in application-specific versions: as hollow and solid shaft gear units, and for shaft, flange or foot mounting. The company’s electric motors can be added as an integrated solution. Motor mounting via an IEC/NEMA adapter is also possible.
