Straight cut gears can provide some exciting benefits, but despite those benefits, regular passenger cars don't use them. Here's why.

Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Pitch: Standard pitches are usually whole numbers when measured as diametral pitch P, the ratio of the number of teeth ...

Scientists create toothless liquid gears that rotate on their own and could revolutionize modern industrial engines.

A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The invention holds potential for a new generation of mechanical devices that offer ...

Gears have been around for thousands of years, with the first records dating back to 3000 BC. While they have advanced over ...

A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European ...

I am pretty certain lots of folk know, but this ex-electronic engineer didn’t – apart from that they must be to reduce friction in some way. Now I know a little more, though this YouTube video by ...

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 ...
