New washdown versions of Nord's helical bevel gear units

Manufactured from die-cast aluminium, the gear unit housings resist corrosion considerably better than steel models. Through additional measures, such as the NSD tupH surface treatment, they can be equipped with extra protection for specific applications. The gearboxes are particularly suited for use in conveyor technology and in the food industry. Further applications include hoists, storage facilities and overhead conveyor systems.

There are five frame sizes with torques ranging from 90 to 660Nm. All models are available in two versions: an open frame style -lightweight, yet with a very sturdy construction - and a closed type. Designed according to the proven UNICASE principle, the gear unit housings require neither an inspection cover nor a screw-on input cover, and are therefore especially small and lightweight. Compared with its predecessor model, the power density has been improved by 60 per cent while the lubricant volume has been minimised. Since the installation measurements remain essentially the same, users can easily replace existing gear units.

These new gear units feature larger, highly resilient output shaft bearings and are therefore suited for high forces. If required, optional double seals ensure increased safety. The gear units are equipped with a short IEC adapter. They can be combined with Nord's complete state-of-the-art range of motors and with motors from other manufacturers - allowing customers to flexibly configure drive systems. The washdown gear units are expected to be available from the second quarter of 2012.
