Scientists create toothless liquid gears that rotate on their own and could revolutionize modern industrial engines.

Fair warning: watching this hybrid manufacturing method for gear teeth may result in an uncontrollable urge to buy a fiber laser cutter. Hackaday isn’t responsible for any financial difficulties that ...

is a powerful and comprehensive computer program for gear design, analysis, optimization and troubleshooting of gear drives. It integrates a virtual gear generator with algorithms for tooth contact ...

Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Pitch: Standard pitches are usually whole numbers when measured as diametral pitch P, the ratio of the number of teeth ...
