Velocity reducers are fairly simple bits of machinery. A acceleration reducer is merely a gear train between the electric motor and the machinery that can be used to reduce the quickness with which power is transmitted. Speed reducers, also called gear reducers, are mechanical devices more often than not utilized for two purposes. Gear reducers essential use is to duplicate the way of measuring torque produced by an info power supply to expand the measure of usable work.
Speed reducers primarily serve two functions. Initial, they take the torque developed by the energy source (the insight) and multiply it. Second, swiftness reducers, much as the name implies, reduce the velocity of the input so that the output may be the correct speed.
How does a velocity reducer increase the torque whilst decreasing the acceleration? The 
output equipment of a rate reducer has more the teeth than the input gear. So, while the output equipment might rotate more slowly, reducing the acceleration 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 gear speed reducer shapes and sizes, but some of the most commonly found swiftness reducers are gearboxes.
