What are Sprockets?

Sprockets are mechanical wheels that have teeth or spikes that are meant to move the wheel and rotate it with the chain or belt. The teeth or spikes engage with the belt and rotate with the belt in a synchronised manner. To work efficiently it is extremely important for the sprocket and the belt to have the same thickness.

 

The basic design of sprockets is almost similar all over the world and they are extensively used in some specific industries like cars, bicycles, motorcycles, and other types of machinery to mechanise various functions and applications.

 

What are the different types of Sprockets?

There are different types of sprockets available in the market, in different shapes and sizes and with different numbers of teeth or spikes. They are divided into the following categories according to the above-mentioned distinctions:

Double Duty Sprockets- These sprockets have two teeth on every single pitch.

Multiple Strand Sprockets- These sprockets are used where surplus power and torque are required.

Idler Sprockets- These sprockets are used along with long chains to eliminate uneven load distribution.

Hunting Tooth Sprockets- These sprockets have an uneven number of teeth to last longer than the other types of sprockets.

 

What is the working mechanism of Sprockets?

The working mechanism of sprockets is excessively simple to understand. In order to function properly, one sprocket serves as the “driver” and the other as the “driven,” and they are connected by a chain or belt. They are then propelled by force or motion, which transfers power or modifies the torque or speed of a mechanical system.

 

Sprockets with more teeth can carry larger loads, but they also generate more friction, which slows down movement.

The notches wear away when a chain passes over them, so if the tip has sharpened or become caught, they need to be replaced.

 

What are some common uses of Sprockets?

Sprockets are frequently used on bicycles to pull a connected chain that causes the rider’s foot motion to rotate the wheels.
