Speed reducers are fairly simple pieces of machinery. A acceleration reducer is merely a gear teach between the engine and the machinery that is used to reduce the velocity with which power is transmitted. Quickness reducers, also called equipment reducers, are mechanical devices more often 
than not utilized for two reasons. Gear reducers essential make use of is certainly to duplicate the measure of torque produced by an details power resource to expand the measure of gear speed reducer usable work.
Speed reducers mainly serve two functions. First, they take the torque developed by the power source (the insight) and multiply it. Second, rate reducers, much as the name implies, reduce the quickness of the input so that the output may be the correct speed.
How does a acceleration reducer raise the torque whilst decreasing the velocity? The output equipment of a velocity reducer has more teeth compared to the input gear. So, while the output equipment might rotate more gradually, reducing the velocity of the insight, the torque is increased.
So, last but not least, they take an insight power source and increase the torque while decreasing the speed.
Speed reducers can be found in many shapes and sizes, but some of the most commonly found rate reducers are gearboxes.
