It's counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers have now figured out why. It's the ...

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 ...

• 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 ...

Gears are toothed wheels that transmit motion from one shaft to another and determine the speed, torque, and direction of rotation of machine elements. Gears can be grouped into two major categories: ...

A recently granted patent (Publication Number: US11998973B2) discloses a method for manufacturing gears using a unique process involving the rotation of a workpiece and a tool around different axes ...
