Why Use Reduction Gears Epicyclic Reduction Gear unit Worm Gear Reduction Unit

One of the most simplest and common types of Reduction Gear Units is the use of worm gear, applied in auxiliary machinery. While single as well as double helical gears are applied in ships with more complex type mechanism of propulsion machinery. Main Reduction gears are generally identified by the series of steps undertaken for bringing in speed reduction as well as the arrangement of the gearing. On that basis a classification is made about the type of Reduction Gears. There are following types of Reduction Gear.

Why Use Reduction Gears?

One of the best ways to know why Reduction Gear Unit are used or why so much importance is attached to Reduction Gears is to understand the operation of Reduction Gears in terms of the engines used to drive a ship. In a ship, for greater efficiency steam turbines are required to operate with a relatively high range of rpm. While for an effective functioning of propellers a relatively low rpm range is needed. The Reduction Gear Unit accomplishes perfectly the task of obtaining the necessary propeller rpm for ship propulsion. A few popular types of reduction gear units are discussed here.
