The 3 Fundamental Functions Of Gears


If we are to illustrate how a gear motor works, the simplest example is the case of a bicycle. The power is being transmitted from the pedals of the bike to the wheels at the back through the chain. The same principle applies to cars wherein power is transferred from the crankshaft that is connected to the engine to the driveshaft that moves the wheels. The principle of each gear motor follows exactly the same idea of power transmission. However, our gears can be connected together to form different sizes based on the specific use. Once power has been transferred from the gear to the other components of a machine, three primary factors can occur. 


#1. Force is increased


Gear motor comes in various types and configurations. However, the same operating principle is at work if two different gears come together with the first wheel having fewer teeth than the second one that has more or bigger wheels. The latter is expected to turn slower than the former but it has more force.


#2. Speed is increased


In this gear application, the first wheel has more teeth or is bigger in size than the second wheel. Now, if the second wheel has to move faster to keep pace with the first one, the gear moves quicker but lower force is used. This means the first wheel with more teeth becomes two times faster than the second wheel but uses less force.


#3. Direction is altered


This third scenario also applies to most gear motor varieties. The scenario is that when two gears come together, one of them turns clockwise while the other one moves counterclockwise. In other words, one gear always turns in the opposite direction of the other gear to deliver the required force or speed. However, there are some special types of gears that are designed to work differently for special applications.
