Reverted gear trains and everything you need to know about them!

Reverted Gear TrainsReverted gear trains are specific mechanical systems. When the axes of the first gear and the last gear (last driven) are co-axial, we call than a reverted gear train.

Simple reverted gear trains consist of two shafts and each of those carry multiple compound spur gear. A compound gear, on the other hand consists of two gear of different pitch diameters. In addition, they are attached to one another.

Furthermore, the reverted gear trains consist of four double spur gear. The gear ration here is 3:1. An assembly like this has two configurations. The first one allows us to convert a slow shaft input speed to a fast output speed. On the contrary, the second allows us to convert a fast shaft input speed to a slow output speed.

Of course, the user can choose to change from one configuration to another by dis-engaging the crank component from one of the shafts. Then, he has to re-engage it to the opposite shaft.

As I’ve already mentioned, the reverted gear trains are quite similar to the compound gear trains. The fact that makes them not so opposite is that they both use small space between the output and the input shafts. Moreover, they are really important to a user because they allow him to make large changes in speed and power. You are bound to need that at a certain point in your life if you are into this kind of stuff.

On the other hand, the reverted gear trains and the compound gear trains have their differences. The first and foremost is that the output and input shafts of a reverted gear train must be on the same axis. They have to be in a straight line with one another so the whole thing that work. The second, huge difference between them is that the centers of the two gear in question, in each pair, have to be the same.
