What Is a Speed Reducer?

So, what exactly is a speed reducer? Well, the term is relatively self-explanatory; speed reducers are components that serve the simple purpose of reducing the speed at which power is transmitted through a system. Speed reducers tend to be relatively small and rudimentary machinery components. They're also known as gear reducers and can come in various forms, such as offset helical hollow output speed reducers, inline speed reducers, and parallel shaft speed reducers. Each type has its own distinct features and design to work in different systems and different areas of a machine, but they all provide the same basic functions and outcomes.

What Are Speed Reducers Used for?

As the name implies, the main purpose of any speed reducer - from an inline speed reducer to a right angle bevel speed reducer - is to reduce the speed at which power is transmitted in a machine or system. They do this in two distinct ways: firstly, they multiply the torque that is being produced by the power source, and secondly, they reduce the speed of the input and thereby slow the rate of power transmission. They do this by having more teeth on the output gear compared to the input gear, so the output gear rotates at a slower speed, thereby reducing the overall transmission speed. This is why they’re such common components in gearboxes.

The Best Speed Reducers

When it comes to mechanical power transmission parts and accessories, like speed reducers, gear racks, clutches, brakes, and silent chains, quality is of the utmost importance. It's vital to use good quality parts to get the high levels of performance and safety that you desire, and Motion Industries only ever stocks and sells the finest components and devices.
