Two-stage helical bevel gearboxes with output torques up to 50Nm

NORD DRIVESYSTEMS has expanded its latest series of slim two-stage helical bevel gearboxes, adding a smaller unit for output torques up to 50Nm. High efficiency helical bevel type units now complement the company’s existing line-up of worm gearboxes.

The gear units are said to be resilient and can withstand large forces on the output shaft. The short-term overload tolerance is claimed to be 275%, which leaves enough time for the motor protection to kick in. Mechanical blockages usually do not cause damage, and the drive can start up again without service interruption.

The units are available for gear ratios from 3.58 to 61.88. They add a new size to the existing series that now comprises six sizes with output torques up to 660Nm. All versions are said to feature a high power density, ensuring robust reliability and easy handling. By default, the gearboxes also support reverse operation.
