The principle of clock rotation is how to turn.

There are many structural forms of mechanical clocks and watches, but their working principles are basically the same. They are all composed of prime mover system, transmission system, escapement governor, pointer system and winding system.

Mechanical clocks and watches take clockwork as the power system, and drive the escape governor through a transmission system composed of a group of gears; Then the speed of the transmission system is controlled by the escape governor in turn; The transmission system drives the pointer mechanism while pushing the escapement mechanism, and the rotation speed of the transmission system is controlled by the escapement mechanism, so the pointer can indicate the time on the dial according to certain rules; The winding pointer system is a mechanism for winding springs or moving pointers.

Extended data:

A set of transmission gears that transmit the energy of the prime mover to the escapement governor consists of two wheels (central wheel), three wheels (passing wheel), four wheels (second wheel) and the pinion shaft of the escapement wheel, wherein the blades are driving gears and the pinion shaft is driven gears. The tooth profile of clock transmission system is mostly modified cycloidal tooth profile based on theoretical cycloidal principle.

The prime mover is a mechanism for storing and transmitting working energy, which usually consists of a box wheel, a box cover, a lever shaft, a spring and a spring hook. When the spring is in a free state, it is a spiral or S-shaped spring with a small hole at its inner end, which is sleeved on the hook of the rod shaft.

Its outer end is hooked on the inner wall of the box wheel through the clockwork outer hook. When winding, the winding needle system rotates the winding shaft and tightly winds the spring on the winding shaft. The elastic action of the spring makes the box wheel rotate, thus driving the transmission system.
