Sprockets are generally used in machines driven by chains. The sprockets help the machine to transmit power to another shaft. You might have seen a similar mechanism in bicycles. The main work of the sprocket is to ensure a rotary motion in a machine. It is a simple process that runs with a gear between two shafts.
In this article, we will talk about the functions, types and application of roller chain sprockets so that you can choose the right device for your operations. If you are planning to purchase such sprockets, the information may help you a lot.
What are Roller Chain Sprockets?
In simple words, roller chain sprockets are wheels with teeth designed to hold a chain. Sprockets are nothing to do with pulleys, gears or impellers, as they do not work with another sprocket directly. They require a chain to transmit the power to another sprocket or shaft. The mechanism is quite simple and you can find it in various types of machines, bicycles, motorcycles, vehicles, tracked systems, etc.
Most of the sprockets are made of metal and you can also find sprockets made of plastic. You can choose a sprocket by the number of teeth and pitch.
How to Choose the Right Type of Chain Sprockets
Before you make any purchasing anyone without any knowledge, you must be aware of some factors that will determine the functionality and efficiency of a roller chain sprocket. If you know the pitch and the number of teeth, you can follow the below-mention factors to choose the right sprockets. Here are the factors you need to look at when investing in roller chain sprockets.
- Load classification
- Speed ratio between the driver and driven sprockets
- Transmittable power
- Source of power
- Driven machine
- Space between the two sprockets
When choosing the best roller chain sprocket, you have to ensure maximum service life, uninterrupted operation and high-end performance. You have to know the chain number, as this is one of the easiest ways to identify a sprocket size. Pitch, on other hand, indicates the length between two adjacent poles or chain links.
You can get the pitch length in millimetre or inches. The speed ratio between the driver and driven sprockets can be calculated by the number of teeth on the driving sprocket and the driven sprocket wheel.
For instance, if you have a 50 tooth driver roller chain sprocket, which transmits power to a 100 tooth driven sprocket, the ratio of speed will be 2:1. Hence, if the driver sprocket spins at 1800 RPM, the speed of the driven sprocket will be reduced to 900 RPM.
What Kind of Roller Chain Sprockets You Should Purchase
If you are planning to purchase multiple roller chain sprockets you should have an idea of the utility and if it will serve your purpose. Hence, the sprockets you have chosen for your project must be of high quality for durability. The process of manufacturing and materials used will determine their strength and durability. Some manufacturers make the body of sprockets with glass-reinforced nylon, which gives the product many advantages.
A roller chain sprocket can be made of cast iron, steel, stainless steel or plastic. Sprockets made of cast iron are the most economical and you can prefer them if you have a tight budget in mind.
These are some important information you may need before you purchase roller chain sprockets for your project. Remember, a worn roller chain sprocket can damage the chain. Hence, never operate a machine with a worn sprocket. Find a reputable manufacturer and order roller chain sprockets as per your requirement.
