Industrial Chain Sprocket

Industrial Chain Sprocket

sprocket is a simple mechanical wheel with teeth. They are designed to rotate and engage with the links of a chain or belt. To be able to operate properly both the chain and the sprocket need to have the same thickness and pitch.

What is Chain Sprocket?

A Sprocket is a wheel with teeth which locks onto a chain. When the sprocket rotates, the teeth hold the chain and drive the chain together with the other parts attached to the chain. This operation provides a controlled rotational movement of large equipment and machinery.

A sprocket is manufactured from metal or reinforced plastic to handle the force of a moving chain.

Sprockets make direct contact with a variety of chain rings unlike gears which interlock together to transfer rotational movement. They are distinguished from a gear in that sprockets are never meshed together directly

Sprockets are parts that are made with specific chain rings to correctly fit and handle specific loads. Sprockets need to meet tight specifications regarding factors such as:

  • Size
  • Dimensions
  • Diameter
  • Teeth width and depth

Choosing the proper sprocket is crucial because it can cause you heavy loss when using a wrong sprocket where the teeth would chip or break. On the other hand, the sprocket with the correct chain can move without breaking, even in heavy-duty conveyor system applications.

 

What is Sprocket Used for?

Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc.

Sprockets and chains are used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.

Sprockets are mostly used for three main purposes: transmitting power, carrying materials on conveyors and carrying loads in lifting vehicles.

Sprockets are used mainly for the following applications ;

  • Agricultural and farming equipment
  • Automotive equipment
  • Chain-driven machinery, such as conveyor belts and other factory systems
  • Pulleys, shafts, and other power transmission equipment
  • Vehicles, such as bicycles and motorcycles

 

What are the Types of Sprockets?

Different types of sprockets have different hubs. A hub is the added thickness around the central plate of a sprocket that doesn’t include the teeth. There are four main types of chain sprockets as established by the ANSI:

  1. Type A sprockets,which are only the plate with no added thickness or hubs.
  2. Type B sprockets,which have a hub on one side.
  3. Type C sprockets,which have hubs of equal thickness on both sides of the plate.
  4. Type C offset or Type D sprockets,which also have two hubs. However, each hub has a different thickness, making the sprocket asymmetrical.

The different types allow for different applications. Type A and B sprockets fit easily against Equipment with tolerance, while Type C sprockets are generally larger and need more thickness to support weight.

 

Special Sprockets

System performance highly depends on chain-sprocket interaction, which means your choice of sprockets can elevate your operation’s success. As Makelsan Chain we provide the right type of sprocket that corresponds with the matching chain.

Our Productıon Range Covers Various Designs Of Sprockets:

  • in single and double sided hub design
  • divided sprockets
  • sprockets with bolted-on segments or tooth shells
  • shear-pin sprockets

 

Roller Chain Sprockets

These are the most common types of sprockets used. They work only with chains designed by rollers interconnected by pins.

Roller chains provide a gap that fits the teeth of the sprocket to transfer rotary motion. These are used in transmission equipment applications.

 

Chain Sprocket Price

The performance of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is just as important as choosing the right chain.

Sprockets are a decisive factor in the capability and service life of every chain system. We therefore produce our own sprockets to ensure the high quality of all products.

We supply the corresponding sprockets for all chains. We produce in high quality materials with tempered and additionally inductively hardened teeth.

FAQ

The majority of conveyor chain manufacturers will state that the rate of elongation must not exceed 3%. If it is 3% or above, it is time to replace your roller chain.

If the roller chain has not been replaced, it can cause the chain to dislodge from the sprockets and cause a power transmission failure with broken links causing potential damage to other components of the product.

Check the adjusters on your swingarms. If you have maxed out the available adjustments , you should replace both your chain and sprockets. By pulling on the chain at the very rear of the sprocket, the sprocket teeth must stay inside of the chain links.

From where you would usually tension the chain, turn the wheel and check in several spots around the whole length for tight spots. If you find excessive tight areas where the tension differs significantly, you have stiff links. A thorough clean and re-lubrication can help.

Carefully examine your sprocket’s teeth the whole way around. Bear in mind that alloy sprockets will wear faster than those made of steel.

We advise replacing both the chain and sprockets at the same time to ensure both peace of mind and optimum performance delivery. It’s true that you don’t need to always replace them at the same time, however in our experience, it’s best to keep it simple and consistent.

An easy way to check for a worn chain is to try to pull the chain away from the rear of the sprocket on the rear wheel. If the chain is worn, you’ll reveal about half a tooth of the sprocket. A new chain will wrap around the sprocket snugly and won’t pull away.

Chain wear and stretch will cause grouping and excessive wear to the sprocket, a major cause of whipping. Poor Sprocket Alignment creates heat and may even bend the shafts on the drive system, causing great damage. Poor Pitch Integrity of chain and sprockets also causes premature failure.

  • Chain size is commonly referred to as Pitch. In actuality, chain size is determined by the chain pitch. Pitch refers to the measurement from one roller-pin center to the next roller pin center of a given chain.
  • ANSI (American National Standard Institute) chain pitch is always measured in 1/8” increments

If you have a sprocket and you need to measure the chain size, if you have just the sprocket, you can use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth to find the measurement of the pitch. Once you know the pitch you can determine the chain size you need

  • Cast iron, which are mainly used in large gear ratios and heavy operating conditions. Cast Iron is the most common and economical material for flat wire belt sprockets, they are accurately cast from high grade iron. Other diameters can be provided on special order.
  • Plastics – which are mainly used for low load conditions, depending on the design of sprocket as per the load conditions where in the lightweight gigs the maximum marks for in the use in idlers,wood processing machines,packaging machines , bottling machines etc. All plastic sprockets meet USDA and FDA for food contact.
    1. UHMW Polyethylene can withstand continuous temperatures up to 180 degrees F.
    2. High Temp UHMW Polyethylene can withstand continuous temperatures up to 220 degrees F.
    3. Nylon sprockets provide 2-3 times the strength of UHMW and can withstand higher temperatures.
  • Steel alloys – used mainly for medium and heavy load applications. FL sprockets have no flange and a hub sticking out one side to allow debris to fall through the belt.
  • Stainless Steels – Both Steel and SS falls in the medium and heavy load applications. Fully machined flangeless (-FL) or machined tooth (-MT) sprockets made from various stainless steels are also available.

The selection of material is purely depending on the loading conditions and gear ratios required. If the material has the attributes to fit your design then any material can be used. So the listed materials can be used or cannot be used. But these are some commonly used materials in the sprocket.
