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 ...

, '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.

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 ...

Witness intense metalworking as damaged gear teeth get rebuilt through brazing, welding, machining, and precise milling to restore perfect function. Heavy-duty techniques fill broken sections with ...

Gears fill the cases of automotive transmissions and are widely used in aerospace applications, but these simple tools are deceptively complex to manufacture. We thought it would be good to take a ...

Helical gears are cylindrical disks which have involute-shaped teeth cut into their face at a helix angle. By slanting the teeth, helical gears can obtain a large contact ratio and the gradual change ...
