What is the basic function of an ancillary gearbox?

An ancillary gearbox is a mechanical component used to transmit power from the main engine or turbine to various auxiliary systems, such as generators, pumps, or hydraulic systems. It typically reduces the speed of the engine's output while increasing torque, allowing these systems to operate efficiently. By providing this power distribution, the ancillary gearbox supports the overall functionality and reliability of the engine or turbine system.
