What does a reverted gear drive do?

A reverted gear drive is a mechanical system that changes the direction of motion and alters the speed or torque of rotating machinery. It typically consists of two gear sets arranged such that the output shaft rotates in the opposite direction to the input shaft. This arrangement is commonly used in applications where space is limited, or where a specific orientation of the output is needed while maintaining compactness. Reverted gear drives are often found in automotive transmissions and various industrial machinery.
