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 and NG500 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.

CAD-Data

• Compact design thanks to integration of planetary carrier in impeller
• High radial loads thanks to direct transfer of force to vehicle frame
• Long service life and low noise emissions thanks to separation of gear and impeller
• Short delivery times and high efficiency with geared platform (NG250/500):
  – Single or two-stage planetary gear (i = 4, 5, 8, 16, 20 and 32:1)
  – Polyurethan wheel, Ø160×50 mm (NG500) or Ø125×50 mm (NG250)
• Maintenance-friendly design, e.g. thanks to the option to easily change wheels

• Drive systems fully developed in line with customer specifications including motor, brake, encoder and controller
• Individual motor adaptation, through specially adapted stub shaft and motor bolt circle
• Protection against intake of debris via brush seal
• Adaptation of the polyurethan impeller
  – Individual materials (better floor preservation and rolling performance, antistatic tread, etc.)
  – Further sizes (Ø140 – Ø200x50mm)
  – Special wheels and profiles (pneumatic tire, outdoor profile, etc.)
• Compliance with international standards
  – Protection class IP67, UL-certification, ATEX-certification
• Excellent flexibility for customer-specific adaptations based on the modular principle:
  – Individually configured radial loads
  – Custom sizes
  – Helically toothed planetary carriers
  – Individual materials, e.g. thermoplastics
  – Other ratios (e.g. i = 25, 40 and 64:1)

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.
