April 13, 2007 A bicycle 517 years in the making? Well, perhaps not - Leonardo Da Vinci's original mind-boggling sketches of the first Continuously Variable Transmission (CVT) used a spiral shaped cog ...

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 ...

CEDAR PARK, TX--(Marketwired - March 14, 2017) - Fallbrook Technologies Inc., the inventor of the NuVinci continuously variable planetary (CVP) transmission technology, today announced that NuVinci ...

• Planetary units with helical gears, rather than spur gears, have higher torque capacity and run quieter. • Different manufacturers measure and rate backlash in different ways. • Software tools for ...

There was a time when print-in-place moving parts were a curiosity, but [Tomek] shows that things are now at a point where a hand-cranked turbine blower with integrated planetary gears can be entirely ...

Harmonic Drive has integrated high precision, compact design and reliability to develop the new range of HPGP planetary gears. Unlike conventional planetary gears, the new series offers consistent ...

Manual gearboxes are pretty simple. I remember my high school physics teacher diagramming one on the chalkboard: power goes in on one shaft, goes through a couple of wheelie-looking things, and boom, ...
