trochoid
Rolling circle's path
A trochoid is a curve traced by a point on or connected to a circle as that circle rolls along a straight line or another circle.
The term appears primarily in mathematics and engineering, where trochoids describe the paths of rotating mechanisms like gears and wheels.
As an adjective, trochoid describes something resembling or relating to such a curve, or in anatomy, a pivot joint that allows rotation around a single axis.
