Designers generally turn to gear reducers in servopositioning applications for two reasons. First, many applications require less speed and more torque than economically available from a servo-motor ...

If you’ve ever been to a Maker Faire, perused Thingiverse, or been within 100 feet of a 3D printer, you’ve probably seen a plastic set of planetary gears with a little crank or maybe a set of ...

The transmission for most vehicles can be configured according to the scheme presented here. Such a transmission may be ...

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 ...

The choice between helical and spur gears in gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you ...

On a regular bicycle crankset, the chainrings turn in a 1:1 ratio with the crank arms. In the case of the Ultime Ti crankset from French company MG Tech, however, things are a little different – an ...

Here’s a very neat idea Yelvington Trikes presented at the 2014 AIMExpo, a bike show which is getting underway in Florida as we write. The idea is not exactly a science breakthrough, but is a “why ...
