How to Choose the Material of Sprocket?

Chains and sprockets are indispensable elements in power transmission. The have an edge over all other methods of power transmission particularly when the drive and the driven point are situated at short centre distance from each other.

 

Chains and Metal stamping are indispensable elements in power transmission. The have an edge over all other methods of power transmission particularly when the drive and the driven point are situated at short centre distance from each other. They are also called as roller chain and sprockets because of the rollers that are used in the link.

 

Before we proceed to look at the constructional and classification aspects of the chain drive, we shall look at the salient points of the chain drive

 

The chain drive eliminates slip and creep and hence provides a constant speed ratio.

The chain and the sprocket both in majority cases being manufactured out of steel tend to wear out at a slower rate and hence a long life is always obtained.

They have the flexibility of a belt drive and can hence be used to drive a number of shafts from a single source.

They have the capability to work in very dirty environments with minimum care.

Here is a good example of the chain drive we use in our day to day life. The chain and sprocket drive in a bicycle. It is the best example for transmission of power from one point to another with a constant speed ratio.

Constructional aspects of Chain:

The chain is the main member in a chain drive made up by means of links interlocked by pins and rollers of specific diameter. The pins are arranged in a series at accurately timed intervals or pitch in order to match the pitch distance in the sprocket.

 

The material used for the manufacture of chains is alloy steel and they are normally punched out of steel plates.

 

The chains and sprockets are selected based on the torque to be transmitted. There are certain classification of the chains and sprockets based on the number of chains being used to transmit the torque. They are

 

When a single chain is used it is called a single strand.

When two chains are used (side by side) it is called as duplex or double strand

When three chains are used, it is called as triplex strand.

 

The chains are basically specified on standardized numbers in various standards like ISO, DIN , ANSI, etc.

Construction aspects of Sprocket:

The sprocket is normally made of alloy steel and is tempered and case hardened at the tooth area in order to enhance the wear resistance of the material. By construction the sprockets either posses a hub with key for driving or holes (in automobiles) in order to be mounted.

 

How to choose the material of sprocket?

The sprocket is a transmission part, used in conjunction with the chain. Just like the use of gears with racks.

 

The commonly used materials for sprockets are generally 45 #. That is ordinary 45 # steel. Ordinary 45 # sprockets can already meet the use conditions of sprockets.

Of course, some people choose 40Mn (40 manganese steel), 45Mn (45 manganese steel). There is a qualitative gap between the manganese steel sprocket and the 45 # sprocket.

 

Of course, the choice of sprocket material depends on the needs of use. If the speed is low. Less pulling force. In the choice of sprocket material, you can choose the 45 # sprocket material with relatively high cost performance.

 

Stainless steel sprocket:

The commonly used stainless steel materials for sprockets are 201 stainless steel, 304 stainless steel, and 316 stainless steel. The most prominent is 304 stainless steel. In terms of corrosion resistance, 304 can basically meet the demand for sprocket materials.

 

The sprocket made of 201 material has a lower corrosion resistance than the sprocket made of 304 material.

 

316 material sprockets are mostly used in coastal cities. The 316 material sprocket has strong corrosion resistance to salty substances.If you want to learn more about our chains and sprockets for sales, you can contact us through our website or send us an email.
