A pinion gear rotates when it is driven by another gear or motor. As the driving gear turns, its teeth engage with the teeth of the pinion gear, causing it to turn in a specific direction. The rotation of the pinion gear can then transfer motion to another component in a mechanical system, such as a rack or another gear. The speed and torque of the rotation depend on the size and arrangement of the gears involved.
The word is downshift.
A gear that turns another gear is called a "driving gear." When the driving gear rotates, its teeth engage with the teeth of the adjacent "driven gear," causing it to rotate as well. This interaction allows for the transfer of motion and torque between the two gears, enabling machines and mechanisms to function efficiently. The size and number of teeth on each gear determine the speed and force of the motion transmitted.
