Gearboxes (Gear Reducers & Increasers) Gearboxes, also commonly referred to as Gear Reducers, Gear Increasers, Speed Reducers or even “Gearheads,” help increase or reduce the torque output of a motor. Gearboxes are mechanical devices that improve the working capacity of motors by lowering or increasing their gear rotation speed to provide the torque and acceleration needed for their driven loads (e.g., conveyors) to work correctly.
