Traditional gear design limits the performance of mechanical drives. Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically ...

Straight cut gears and made a little differently than what you'll find on non-racing vehicles. Here's how they work and why cars built for racing use them.

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 ...

The production of noiseless gears requires that minute errors in tooth-curves be avoided. Objectionable sound-waves are caused by a gear-tooth error of 0.0003 in. and ...

The broaching process, similar to shaping with multiple teeth, is used to machine internal and external surfaces such as holes of circular, square, or irregular shapes, keyways and teeth of internal ...

Lasercutters are fantastic tools: they’re highly useful for making flat things, or even flat things that you later bend! This makes them particularly well suited for making gears out of flat stock.

Makers, engineers and hobbyists who would like to automatically manufacture a variety of different size plastic gears you might be interested in a unique machine built using a little Arduino hardware, ...

Different gears like spur, bevel, worm and wormwheel, rack and pinion, meshed gears, and threaded bars serve various purposes. When selecting a gear system, consider speed, direction, force, space, ...

• Planetary units with helical gears, rather than spur gears, have higher torque capacity and run quieter. • Different manufacturers measure and rate backlash in different ways. • Software tools for ...
