n
A coupling that allows different parts of a machine not in line with each other some freedom of movement at the same time as transmitting rotary motion.
n
A machine formed by a combination of a lever with the wheel and axle, in such a manner as to convert the reciprocating motion of the lever into a continued rectilinear motion of some body to which the power is applied.
n
Alternative spelling of valve train [The mechanical system that operates the valves in an internal combustion engine.]
n
An iron shoe placed on the rear wheel of a wagon to retard motion in going downhill.
n
An optical illusion in which a spoked wheel appears to rotate differently from its true rotation, sometimes caused by stroboscopic effects.

n
(automotive) A wheelrim.
n
A simple machine consisting of a wheel (or similar lever) that turns an axle around which a cord is wound; its mechanical advantage is the ratio of the diameters of the wheel and axle.
