Lightweight, hygienic helical bevel gear unitsFor hygienically demanding applications, NORD DRIVESYSTEMS supplies aluminum two-stage helical bevel gear units in five sizes with a maximum torque of 660 Nm that are easy to clean
The washdown design is based on smooth inclined surfaces, transitions with large radii without dead spaces, and requires no assembly covers. Cleaning liquids wash off easily and completely from the surfaces, which also remain considerably cooler than those of conventional drives thanks to the special construction. The design is optimized, amongst others, for use in the food industry and complies with international guidelines and standards such as EHEDG, ANSI / BISSC, and ANSI / NSF. If required, the gear units can be fitted with double shaft seals. They can be ordered as open or closed frame versions with hollow or solid shafts.

Designed according to the proven UNICASE principle, the housings are very torsion-resistant and withstand high mechanical stress. With the optional NSD tupH surface treatment, they become extremely resistant to corrosion as well as acids and alkaline solutions. NORD's CleanDRiveSolutions is not a coating, which means that no layers can peel. Instead, the process transforms surfaces with up to seven times the hardness of the base aluminum material. Thereby, the housings acquire robustness and durability qualities that are similar to stainless steel versions, while remaining much lighter and more economic. In addition to food industry processes, the gear units are also ideally suited for conveyor systems and hoists, especially in applications where geared motors have to be moved and their light weight becomes essential. All gear units can be combined with suitable smooth-surface motors from NORD or other manufacturers.
