What is the difference between gearbox and gear reducer

Acceleration reducers are mechanical devices generally used for just two purposes. The principal use is to multiply the amount of torque produced by an input power source to raise the amount of usable work. They also reduce the input power supply speed to attain desired output speeds.
When looking at speed reducer vs. gearbox usually the just difference is terminology. This is because all velocity reducers are gearboxes. … The purpose of the acceleration reducer is to lessen the rpm that’s transmitted between both of these end points. Quickness reducers take the torque produced by the engine (the input) and multiply it
