Speed reducers are fairly simple pieces of machinery. 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.
Speed reducers primarily serve two functions. First, they take the torque created by the power source (the input) and multiply it. Second, speed reducers, much as the name implies, reduce the speed of the input so that the output is the correct speed.
How does a speed reducer increase the torque while decreasing the speed? The output gear of a speed reducer has more teeth than the input gear. So, while the output gear might rotate more slowly, reducing the speed of the input, the torque is increased.
So, to sum up, they take an input power source and increase the torque while decreasing the speed.
Speed reducers come in many shapes and sizes, but some of the most commonly found speed reducers are gearboxes.
Need a Hand Selecting a Speed Reducer?
The type or model of speed reducer which is right for your application will be determined by the application and project specification. However, we recently published a guide designed to help you navigate the world of speed reducers and speed reducer suppliers. This free download will guide you through the ten most important aspects of selecting a speed reducers supplier, and also a speed reducer.
