Mechanically preloaded splitpinion drives have an axial spring to load one pinion half against the other. And electrically preloaded dual-pinion drives have two motors, each driving one pinion, which ...

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.

What if the future of precision mechanics didn’t rely on massive manufacturing plants or multimillion-dollar R&D budgets, but instead emerged from a 3D printer on a hobbyist’s workbench? That’s ...
