INSTALLATION AND USING

The chain spocket, as a drive or deflection for chains, has pockets to hold the chain links with a D-profile cross section with flat side surfaces  parallel to the centre plane of the chain links, and outer surfaces at right angles to the chain link centre plane. The chain links are pressed firmly against the outer surfaces and each of the side surfaces by the angled laying surfaces at the base of the pockets, and also the support surfaces of the wheel body together with the end sides of the webs formed by the leading and trailing walls of the pocket.

NOTICE

When fitting new chainwheels it is very important that a new chain is fitted at the same time, and vice versa. Using an old chain with new sprockets, or a new chain with old sprockets will cause rapid wear.

It is important if you are installing the chainwheels yourself to have the factory service manual specific to your model. Our chainwheels are made to be a direct replacement for your OEM chainwheels and as such, the installation should be performed according to your models service manual.

During use a chain will stretch (i.e. the pins will wear causing extension of the chain). Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel.
 

FOR CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references^[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Pitch (inches)	Pitch expressed in eighths	ANSI standard chain number	Width (inches)
1⁄4	2⁄8	25	1⁄8
3⁄8	3⁄8	35	3⁄16
1⁄2	4⁄8	41	1⁄4
1⁄2	4⁄8	40	5⁄16
5⁄8	5⁄8	50	3⁄8
3⁄4	6⁄8	60	1⁄2
1	8⁄8	80	5⁄8

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

How do I prevent chain elongation in a sprocket gear system?

Preventing chain elongation is essential to maintain the efficiency and longevity of a sprocket gear system. Chain elongation occurs over time due to wear and stretch in the chain, leading to a change in pitch length and improper engagement with the sprocket teeth. Here are some measures to prevent chain elongation:

1. Proper Lubrication: Regular and adequate lubrication of the chain is crucial to reduce friction and wear between the chain’s components. Lubricants also help prevent corrosion and reduce the chances of chain elongation.

2. Correct Tension: Maintaining the correct chain tension is vital to prevent excessive stress and elongation. Too much tension can accelerate wear, while too little tension can lead to slippage and increased elongation. Follow the manufacturer’s guidelines for proper tensioning.

3. Quality Chain: Invest in high-quality chains that are designed to resist elongation and offer better wear resistance. High-strength chains with heat-treated components are more resistant to elongation.

4. Proper Alignment: Ensure the sprockets are properly aligned to minimize lateral forces on the chain. Misalignment can cause uneven wear and accelerated elongation.

5. Regular Inspection: Perform routine inspections of the sprocket gear system to check for signs of wear, elongation, or any other issues. Address any problems promptly to prevent further damage.

6. Replace Worn Components: As the chain and sprockets wear over time, replace them when they reach their wear limits. Continuing to use worn components can accelerate elongation and lead to premature failure.

7. Avoid Overloading: Operating the sprocket gear system within its designed load capacity will help minimize stress on the chain, reducing the chances of elongation.

8. Environmental Considerations: In harsh or abrasive environments, protective measures like covers or guards can help prevent contaminants from accelerating chain wear and elongation.

By implementing these preventive measures, you can significantly reduce the risk of chain elongation and ensure a longer and more reliable service life for your sprocket gear system.

How do you select the right size and pitch of a sprocket gear for a specific application?

Choosing the correct size and pitch of a sprocket gear is crucial to ensure optimal performance and efficiency in a specific application. Here’s a step-by-step guide to help you make the right selection:

1. Identify the Application Requirements: Understand the specific requirements of your application, including the desired speed, torque, power transmission, and operating conditions.
2. Calculate the Gear Ratio: Determine the gear ratio required for your application. The gear ratio is the ratio of the number of teeth between the driving and driven sprockets and determines the speed and torque relationship between them.
3. Consider the Pitch: The pitch of a sprocket refers to the distance between the centers of adjacent teeth. It is essential to choose sprockets with the same pitch as the chain or belt you plan to use in your transmission system.
4. Choose the Number of Teeth: Once you have the gear ratio and pitch, calculate the number of teeth for both the driving and driven sprockets. The number of teeth affects the speed and torque characteristics of the transmission system.
5. Verify Shaft Compatibility: Ensure that the sprocket gear’s bore size matches the diameter of your application’s input and output shafts.
6. Consider Material and Strength: Select sprocket gears made from materials suitable for your application’s operating conditions. For heavy-duty applications, choose sprockets with high strength and wear resistance.
7. Check Center Distance: Verify the center distance between the driving and driven sprockets to ensure proper chain or belt tension and alignment.
8. Review Manufacturer Recommendations: Manufacturers often provide guidelines and specifications for their sprocket gears. Review their recommendations and consult with experts if necessary.
9. Perform Regular Maintenance: Once the sprocket gear is installed, conduct regular maintenance, including lubrication and inspection, to ensure longevity and optimal performance.

Choosing the right size and pitch of a sprocket gear requires careful consideration of various factors to meet the specific needs of your application. By following these steps and consulting with experts when needed, you can select the most suitable sprocket gear for your mechanical system.
