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 ...

To meet the demands of helicopter transmission systems characterized by diverse configurations and high-speed, heavy-load operating conditions, the meshing characteristics of helical face gears ...

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 ...

A new series of right-angle helical-gear drives, identified as A 2Z11... Series feature a fiberglass-reinforced nylon housing, hardened steel helical gears, steel shafts, nonmetallic bearings, and ...

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: ...

Since the first observation of a helical flow pattern in aortic blood flow, the existence of helical blood flow has been found to be associated with various pathological conditions such as bicuspid ...

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 ...
