Gearing systems are mechanical devices that transmit power and motion between different parts of a machine. They consist of gears, which are toothed wheels that interlock to change the speed, torque, or direction of movement. Commonly found in vehicles, bicycles, and various machinery, gearing systems help optimize performance and efficiency. There are different types of gears, including spur gears, bevel gears, and worm gears, each serving specific functions. The arrangement and size of these gears determine the overall output, making gearing systems essential for applications ranging from simple tools to complex industrial equipment.
