What are compound gears used in?

Compound gears are used in mechanical systems to increase torque or change rotational speed effectively. They consist of two or more gears that are mounted on the same axis, allowing for more complex gear ratiOS within a limited space. This makes them ideal for applications in machinery, automotive transmissions, and robotics, where precise control of movement and power transfer is required. By combining different gear sizes, compound gears can achieve significant reductions in size while enhancing performance.
