The teeth of teeth of involute gears hobs and teeth for involute spline shaft hobs have a trapezoidal profile. In the U.S. a huge volume of good quality hobs are produced, and offers potential for ...

Some spare time recently got used-up designing a pair of involute gears – which, it transpires, is easy in principle, once certain almost-impossible-to-obtain facts have been gathered. There are ...

, '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.

Following an earlier proposal for transcribing the angle of hob profile teeth measured in inches, our correspondent now describes how to execute a similar task with metric measurements: “The U.S.

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 ...

Gears are toothed wheels that transmit motion from one shaft to another and determine the speed, torque, and direction of rotation of machine elements. Gears can be grouped into two major categories: ...

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 ...

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 ...
