Gear Geometry provides an overview of the important design features of common gears. Involute gears have teeth that are shaped by an involute curve. In order to work properly, involute gears must meet ...

If you’re into CNC machining, mechanical tinkering, or just love a good engineering rabbit hole, you’re in for a treat. Substack’s [lcamtuf] has written a quick yet insightful 15-minute introduction ...

, 'involute gears' and 'cycloid gears', based on the difference in tooth shape. Both types have their own advantages, but technology blogger lcamtuf explains the advantages of involute gears. A ...

Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically, a hob or shaper cutter traverses the gear blank to generate teeth.

Even before the Industrial Revolution, gears of one kind or another have been put to work both for and against us. From ancient water wheels and windmills that ground grain and pounded flax, to the ...
