Gear Technology: From Geometry to Selection
Gear technology is more than the sum of its individual gears. It encompasses the complete geometry — module, pressure angle, addendum and dedendum circles — as well as the full range of gear types: straight and helical spur gears, bevel gears for angular gearboxes, worm gears for high ratios, and rack-and-pinion systems for converting rotation into translation.
From standardized spur gears per DIN 3960 to custom-tooth profiles made to drawing, the choice of material, manufacturing process (hobbing, grinding, honing), and correct sizing for load capacity and efficiency determines whether a gearbox operates reliably and economically. This pillar page links all guides, comparisons, and calculators related to gear technology.
