Hub gears

With unattended operation around the clock, driverless transport systems (AGVs) in warehouses, parcel distribution centres and production halls ensure maximum profitability and reliability when distributing goods, packaging materials or components.

Hub gears from Framo Morat prove their value as wheel drives for AGVs due to the advantageous arrangement of both the bearings and the drive and output shafts. Furthermore, a compact design in confined spaces is possible.

The hub gears are available in the NG250, NG500 and NG750 variants, each in single- and double-stage versions with polyurethan wheels. Moreover, customer-specific adaptations, such as a brush seal for outdoor applications or a toothed belt for use in high-bay warehouses, can be made too.

Framo Morat has developed a highly integrated wheel hub drive that combines all functional elements, such as the wheel, a high-precision planetary gear, a powerful electric motor and a brake and electronics, into one all-inclusive solution. This modular and scalable system boasts high performance in a compact design and lets users make adaptations to the load capacity, torque, interfaces, sensor system and control profiles.

The wheel hub drive is available in two sizes. The RNA250 is suitable for smaller and flatter vehicles. The standard variant features a two-stage gear box, a total system length under 242 mm, and a standard wheel size of 125 mm. This model can handle a load of up to 250 kg per wheel. The RNA500’s total system length of less than 200 mm and its standard wheel size of 160 mm make it a very compact system. With a wheel load of up to 500 kg, it is designed for larger vehicles.
