A yoke and teeth set is a mechanical arrangement that is often used in gear systems. The yoke is a component that connects two or more gears, while the teeth are the ridges or projections on the gears that interlock and transfer power.

In a yoke and teeth set, the yoke is typically shaped like a fork or a U, with two arms that are parallel to each other and spaced apart by a distance that matches the width of the gears. The teeth on the gears mesh with each other as they rotate, transmitting power and motion from one gear to the other.

The number of teeth on each gear, as well as the shape and spacing of the teeth, can be adjusted to control the speed, torque, and direction of rotation in a gear system. Yoke and teeth sets are used in a wide variety of applications, including automotive transmissions, industrial machinery, and mechanical watches.
