Have you been looking for gear reducers but don’t really know what gear reduction is all about? You might have heard about how these devices work but still, you don’t know how exactly they do their job. In order to address this matter, it is best to understand the principle of the reduction gear. In essence, it is a gear set up in which an input speed can be altered to suit specific requirements for slower or faster output speed while still achieving the same output torque or even more. The torque received from the wheelwork is being transferred to the rotating gears where it can be changed.
In typical situations, the number of gears used by gear reducers, also known as gearboxes, depends on the particular speed requirement of a certain application. Their use can be either very simple or quite complicated. Take for example the case of a ship that needs high-speed turbines to sail. In order to become highly efficient, the ship’s steam turbine must work at a high rpm range. However, on the contrary, the propeller should work at a relatively low range of rpm. This is where a gear reduction comes in to alter the high speed from the steam turbine into the low range required by the ship’s propeller.
Gear reducers come in two primary categories - the single reduction gear and the double reduction gear. The former type of gearbox is composed of ports in which the propeller shafts and engine enter. The bigger gear is then being driven by a pinion that is connected to the propeller shaft. Usually, a single reduction gear has a gear that is twice as big as the pinion. The latter type of gear, the double reduction gear is great for application with very high speed. In this setup, a flexible coupling is utilized to mount the pinion to the input shaft, which is then connected to the intermediate gear.
