Gears measured in inches earn 'English module' distinction to prevent confusion. M = OD ÷ N Pressure angle is the angle of tooth drive action, or the angle between the line of force between meshing ...

Gears mate via teeth with very specific geometry. Pitch is a measure of tooth spacing and is expressed in several ways. Pressure angle is the angle of tooth drive action, or the angle between the line ...

Topics include: application of micro-geometry modifications to avoid edge contact and absorb errors of alignment, free-form design of gear tooth surfaces, evaluation of the loaded function of ...

Where most gearboxes have, you know, gears, a magnetic gearbox works by coupling input and output shafts not with meshing teeth but via magnetic attraction. [Retsetman]’s version has three ...
