gear

The wheel is an energy transfer mechanism. Theoretically, the energy of the driving wheel is equal to the energy of the driven wheel. It is mainly used for speed conversion. Since the gear rotates strictly according to the number of teeth during movement, the speed of the driven wheel has a known proportional relationship with the driving wheel. Increasing (decreasing) Torque Torque is the product of force and moment arm. A driven wheel that is larger than the driving wheel can provide greater torque, but of course the speed will be reduced (energy conservation). There are teeth on the rim that can continuously mesh with mechanical components that transmit motion and power. Gears are mechanical parts with teeth that can mesh with each other. The application of gears in transmission has appeared very early. At the end of the century, the principle of the generated gear cutting method and the special machine tools and cutting tools that used this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation received attention. The function of a gear is to transmit the rotation of one shaft to another, and can also achieve actions such as deceleration, speed increase, direction change, and reversal.
