👉 Pinions, also known as gears or pulleys, are mechanical components used in various applications to transmit motion from one part of an assembly to another. They are responsible for converting mechanical energy into electrical power and vice versa. In a typical assembly system, such as a bicycle or motorbike, the pinion is designed to connect two shafts (the main gears) which are connected to the wheels through their pulleys. These pulleys allow the pins to rotate smoothly on each side of the wheel
