Over 10,000 configuration options for planetary gears

The "Modular System for Planetary Gears" offers over 10,000 configuration options. Nine different diameters from 22 to 120 mm with as many as four gear stages and 128 reduction ratios are available in plastic, metal or material mix versions with output torques ranging from 0.2 to 300 Nm. Despite this enormous variety of configuration options the gearbox can be manufactured economically by the mass production of the standardized tooth parts.

Low-noise modules for the first stage, diameter 32 to 105 mm, feature a well-attuned combination of module, number of teeth, helix angle, gearing width and choice of material, guaranteeing ultimate smooth running and high torque capability. With the new tandem planetary gears (patent applied for), even high peak loads are safely transferred. The external dimensions and reductions, identical to those of the straight-toothed gears and differing only in microns, allow easy replacement in most cases during testing or series production.
