Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
The external coils create a harmonic flux when powered with multiple phase AC, which behaves like a variable number of stator rods- thus effecting a variable transmission or variable ratio magnetic gear. This type of gear consumes approximately 25% of its input power in the process, causing current in the external coils.

4th-century sarcophagus, Milan; one of the earliest Nativity images. The earliest representations of the Nativity itself are very simple, just showing the infant, tightly wrapped, lying near the ground in a trough or wicker basket. The ox and ass are always present, even when Mary or any other human is not.
The reciprocating motion of a pump piston is close to but different from, sinusoidal simple harmonic motion. Assuming the wheel is driven at a perfect constant rotational velocity, the point on the crankshaft which connects to the connecting rod rotates smoothly at a constant velocity in a circle.

Small business owners should not forget about a rule — currently in legal limbo — that would require them to register with an agency called the Financial Crimes Enforcement Network, or FinCEN ...
A cycloidal gear is a toothed gear with a cycloidal profile. Such gears are used in mechanical clocks and watches , rather than the involute gear form used for most other gears. Cycloidal gears have advantages over involute gears in such applications in being able to be produced flat (making them easier to polish, and thereby reduce friction ...
