A rotate vector gearbox is designed to rotate the output shaft in the opposite direction of the input shaft in order to change the direction of rotation of the system that it is connected to. This gearbox achieves this by using a combination of gears that mesh together at different angles, which causes the input and output shafts to rotate in opposite directions. This gearbox is often used in situations where a given system needs to have its rotation direction changed without having to redesign the entire system or replace any major components.
