Small, light, helical bevel washdown gearboxes
At this year's Hannover Messe, NORD Drivesystems previewed a new line of performance-optimised two-stage helical bevel gear units. The new units are designed as washdown gearboxes, so cleaning liquids can easily wash off in all installation positions. All external surfaces have been designed with wide radii; there are no indentations or dead spaces.
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. As the installation measurements remain essentially the same, users can easily exchange old gear units for the new models. Additionally, the new models have greater power reserves than their predecessors and therefore allow for the use of smaller sizes in some applications. Moreover, the new gear units are suited for use with NORD's complete range of motors, allowing customers to flexibly configure drive solutions.
The series consisting of models in five different sizes, with torques ranging from 90 to 660Nm, is due on the market at the end of 2011. All units feature a high-strength die-cast aluminium gearcase which is designed according to the proven UNICASE principle.
Since the gearcase requires neither an inspection cover nor a screw-on input cover, the units are especially small and light-weight. This facilitates handling, and helps reduce energy consumption particularly in appli-cations where drives are moved. The new gearboxes provide maximum operational safety, high output torques, high resistance to axial and radial loads and low-noise operation. In addition, they require minimal maintenance and have a long service life.
