स्प्रॉकेट म्हणजे काय?
Sprocket is an item that transmits rotation from a pedal to a wheel. However, sprockets are not just used in bicycle gear systems. They’re also used in transmission equipment, in-vehicle systems, and in other applications where linear motion is transferred from one wheel to another.
Sprockets come in several different sizes and shapes. There are single strand, double strand, and triple strand styles. Each of these sprockets can be made of stainless steel, cast iron, or mild steel. While each style has its own advantages and disadvantages, they all serve the same purpose.
In addition to sprockets that have a fixed number of teeth, there are also those with a fixed or variable pitch. Those with a variable pitch can be manufactured with multiple strands, which is advantageous for higher torque.
Each sprocket has a number of different characteristics. However, each sprocket has several sprocket parts, which include number of teeth, pitch diameter, outside diameter, pitch.
दातांची संख्या: This is the total number of teeth on the sprocket, individually referred to as teeth.
खेळपट्टीचा व्यास: This is the circumference of the sprocket at the inner point between the points where the teeth of the chain intersect the sprocket.
बाहेरील व्यास: The circumference of the tooth end tip around the sprocket.
पिच: The complete measurement of each tooth, usually expressed in inches. This needs to fit the spacing between the pins on the chain.

Types of Sprockets
Sprockets are mechanical devices that transfer motion from one wheel to another. They are used in a variety of applications. They can be manufactured from metal, plastic, or other materials.
The most common types of sprockets are for roller chains. Roller chain sprockets are used in transmission equipment. These chains are made up of teeth that mesh with rollers on the transmission chain.
Industrial sprockets are usually constructed of cast iron or mild steel. Their teeth are normally heat treated to enhance their durability. They are commonly used in applications such as agriculture and power transmission. Some industrial sprockets feature hardened teeth.
Duplex sprockets are made from mild steel or stainless steel. These sprockets can have a single or double hub. They are typically used in applications with a large pitch diameter.
स्प्लिकट्स स्प्लिकेट्स are ideal for limited space and can be easily assembled without the need for a shaft assembly. These sprockets are usually bolted back together to make installation easier.
Chains are used in a variety of applications, from forestry to automotive. They are also used in conveyor systems. Conveyor chains are generally designed with a hunting tooth arrangement to distribute wear among two sets of teeth.
There are many different styles and designs of sprockets. These include the roller chain sprockets, duplex strand, and flat sprockets. Each of these sprockets has a unique design and function.
Regardless of the type of sprocket you choose, it is important to consider the specific application. Depending on the intended use, you may need to select a sprocket with a particular number of teeth, pitch, or overall diameter.

When choosing a chain sprocket, consider its size. This dimension is important for smooth operation. You can measure it using a caliper.
The sprocket must have a diameter that is compatible with the chain.
Pitch refers to the size of a chain. It is measured from the center of the roller-pin to the next roller-pin. A sprocket with a larger pitch will have larger teeth.
The sprocket can have a set of teeth or it can be a hub. There are several common sprocket types: Type A, Type B, Type C, and Type D. All are manufactured to a standard. However, these standards may not apply to all applications.

Chains or belts are used to connect two sprockets, one as a “driver” and the other being “driven”. Motion or force then drives them, thereby transmitting power or changing the torque or speed of the mechanical system.
Sprockets with more teeth are able to move heavier weights, but they create more friction, which reduces operating speed.
Chain Sprockets Selection
Sprockets are available with 1, 2 or 3 rows of teeth to suit the chain they are used on – called simplex, duplex or triplex sprockets. Simplex is the most common type, accounting for about 70% of market applications, duplex for about 25% and triplex for 5%.
The two chain standards that are most commonly seen on the market are: ब्रिटिश मानक (बीएस) - त्याला असे सुद्धा म्हणतात युरोपियन मानक, American Standard (ANSI).
For both standards, you may encounter a range of different chain sizes such as the examples in the following.
|British Standard (BS)/European Standard||04B||05B||06B||08B||10B||12B||16B||20B||24B||28B|
|American Standard (ANSI)||25||35||41||40||50||60||80||100||120||140||160||180||200||240|
The size usually ends with a hyphen followed by a number between 1 and 3. This describes the number of strands required for a particular chain (1 means a simplex chain is required, 2 means a duplex chain, 3 means a triplex chain). For example, “12B-2” means that the chain requires duplex sprockets.
Please note: These are imperial products, i.e. inches. But the dimensions are converted to metric, giving the impression that they are metric products for Europe, which is a metric market. The same is true for chains and hydraulic systems.
You then need to determine the size, OD or tooth number to determine the force ratio.
Gears VS Sprockets
A gear and a sprocket are both components of a machine. However, their applications are quite different. Generally, gears provide greater torque, higher machining accuracy, and larger transmission ratio.
Sprockets are primarily used on bicycles and tracked vehicles. They are driven by chains and are connected by toothed belts. The sprocket wheel is used to guide the chain in a straight line. It is also used to transfer torque with the help of the rider.
Unlike sprockets, gears are not meant to interact with each other. They are not designed to fit in the same grooves or teeth as other gears. Usually, the difference between the two is noticeable only by looking at the grooves and teeth.
When comparing the two, you may notice that a cog has more teeth than a sprocket. This is because a cog has its teeth on both sides of the unit.
Although there is some overlap between sprockets and gears, they are not interchangeable. For instance, a sprocket can’t transmit between two shafts that are parallel to each other. But, a gear can.
There are several other differences between sprockets and गियर. Both have their own individual functions. Generally, sprockets are used for moving a heavy load while gears are used for conveying motion within a machine.
