What Is a Sprocket?

A sprocket is a mechanical device that has teeth that lock onto a chain to rotate it and move other parts attached to the chain. The sprocket is usually made of metal or reinforced plastic to handle the force of the chain, which it rotates.

Sprockets have been around for a long time, and they can be found in a wide variety of applications. They’re used in the transport mechanisms of movie projectors and camera film, and they’re also used to power throwaway disposable cameras and some professional-class bicycles.

There are many types of sprockets, from single-pitch roller chain sprockets to double-pitch sprockets with varying spacings for different applications. The type of sprocket you choose depends on the job at hand, and you should select one that matches your chain’s pitch length.

Roller chain sprockets are the most common type of sprocket, and they’re typically used for power transmission equipment that requires a constant rotary movement. They operate along chains formed by rollers interlinked by pins, and they form gaps that the sprocket’s teeth fit into to transfer movement energy.

These sprockets can be made from a range of materials, including stainless steel and mild steel. They are often stamped from plate, pressed from powder or machined from bar stock.

They can have wide or narrow teeth, depending on the chain’s pitch length. Chains with a larger pitch diameter generally require sprockets with wide teeth, while chains with shorter lengths between roller-pin centers need sprockets with narrow teeth.

The tooth’s hardness is a factor in the longevity of a sprocket, and it’s important to choose a sprocket with a high hardness grade to reduce wear and tear. Some manufacturers charge extra for this option, but a hardened sprocket may last three times longer than a softer one.

A sprocket’s tooth size is another factor in the longevity of a sprocket. Tooth sizes that are too large can cause the sprocket to tilt or slip, and sprockets with smaller teeth are more susceptible to abrasion.

Choosing the right sprocket for your application is crucial to the performance of your equipment and to the safety of your workers. It’s important to match the sprocket’s bore size with that of your drive shaft, so that it doesn’t tilt or slip while turning the shaft.

When you’re comparing the different types of sprockets available, make sure you check out their sizing charts and corresponding chain pitches. You can use these charts to help you choose the best sprocket for your application, and to ensure that you get a quality product that will provide you with excellent service for years to come.

You can also use a sprocket caliper to measure the sprocket’s width, which will give you a clear indication of its overall diameter. This is especially helpful if you’re replacing the same sprocket with different chain diameters, as the sprocket’s caliper can be a good way to gauge whether or not the replacement is compatible with your existing system.
