Big tires and big obstacles can rob you of torque, traction, and possibly wheel speed. Changing axle gear ratios can help and is most often done to restore reasonable gearing for on-road driving with ...

Right-angle gearing often requires engineers to compromise between torque capacity and mechanical efficiency. Hypoid gearing ...

From a load-capacity point of view, the most suitable gearhead ratio has the highest torque density for the most compact (and cost-effective) package. From an application point of view, the best ...

Differences in the track, tire sizes, class rules, and other factors can cause you to rethink your selection of gears, possibly from week to week and even from the beginning to the end of an event (in ...

"Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." — Archimedes (287- 212 B.C.) On the street, everything is a compromise. Power is now easier to make than ...

Few vehicle modifications have as major an impact as changing gear ratios, and it's because your car's gear ratio directly translates to how it delivers power. Think about it: The gear ratio, or how ...

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.
