Frequently Asked Questions (FAQs)

1. What is speed reducer gearbox?

Speed reducers are gear trains between a motor and a piece of machinery. The purpose of the speed reducer is to reduce the rpm that is transmitted between these two end points. Speed reducers take the torque created by the motor (the input) and multiply it.

2. What is the difference between gearbox and gear reducer?

In greater context, the gear reducer is basically a tool used to increase efficiency in facility operations. The term “gearbox” is used to refer to any piece of equipment connecting a motor and a machine that consists of a series of gears, otherwise known as a gear train.

3. What are speed reducers used for?

A speed reducer is simply a gear train between the motor and the machinery that is used to reduce the speed with which power is transmitted.

4. What is speed gearbox?

A change-speed gearbox is a set of movable or constant gears which allows the speed ratio between input and output shafts to be changed either manually or automatically. An overspeed facility is provided through a step-up change-speed gearbox.
