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):

|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |

| 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.

Can sprocket gears be used for vertical power transmission?
Yes, sprocket gears can be used for vertical power transmission in certain applications. Vertical power transmission involves transferring rotational power between two shafts that are oriented vertically, with one shaft positioned above the other. In such cases, sprocket gears, also known as chain sprockets when used with chains, can offer an efficient and reliable solution for transmitting power.
The main advantage of using sprocket gears for vertical power transmission is their ability to maintain a positive engagement with the chain, ensuring a consistent and smooth transfer of power. This positive engagement is particularly beneficial in vertical applications where gravity can potentially cause other types of gears, such as spur gears or bevel gears, to disengage or produce excessive wear.
Sprocket gears are commonly employed in vertical power transmission systems in various industries, including manufacturing, material handling, and construction. Examples of vertical power transmission applications using sprocket gears include:
1. Vertical Conveyor Systems: Sprocket gears, in combination with conveyor chains, are often used to transport materials vertically between different levels of a facility.
2. Elevators: Sprocket gears and chains are utilized in elevator systems to lift and lower the elevator car in buildings or industrial settings.
3. Vertical Lifts: Sprocket gears play a crucial role in vertical lift systems that move heavy loads between floors or levels.
4. Agricultural Equipment: Sprocket gears are used in vertical power transmission systems of agricultural machinery, such as grain elevators.
When implementing sprocket gears for vertical power transmission, it is essential to consider the load, speed, torque requirements, and system dynamics to ensure safe and efficient operation. Additionally, proper lubrication and regular maintenance are crucial for maximizing the lifespan and performance of the sprocket gear system.
Overall, sprocket gears offer a reliable and versatile solution for vertical power transmission, making them a popular choice in numerous industrial and commercial applications.
How do I identify the signs of wear and tear in a sprocket gear?
Regular inspection of sprocket gears is essential to identify signs of wear and tear early on and prevent potential issues that could lead to system failure or reduced performance. Here are some common signs to look for when inspecting sprocket gears:
1. Tooth Wear: Examine the teeth of the sprocket for signs of wear. Wear can manifest as rounding of the tooth profile or a reduction in tooth height. Excessive wear can lead to poor engagement with the chain, resulting in chain skipping and decreased efficiency.
2. Surface Damage: Check the surface of the sprocket teeth for any signs of chipping, cracking, or pitting. Surface damage can occur due to foreign particles, misalignment, or inadequate lubrication.
3. Chain Stretch: Measure the chain’s length to check for elongation or stretch. A stretched chain can cause uneven wear on the sprocket teeth and affect the overall performance of the system.
4. Looseness: Inspect the sprocket for any signs of looseness or play. A loose sprocket can lead to noise, vibration, and premature wear of both the sprocket and the chain.
5. Corrosion: If the sprocket is exposed to corrosive environments, check for signs of rust or corrosion. Corrosion can weaken the sprocket and reduce its load-carrying capacity.
6. Lubrication: Evaluate the condition of the lubricant and ensure the sprocket is adequately lubricated. Insufficient lubrication can accelerate wear and cause friction-related issues.
Regular maintenance and lubrication can help extend the life of sprocket gears and prevent premature wear. If any signs of wear and tear are detected during the inspection, it is crucial to address the issue promptly. Depending on the severity of the wear, repair or replacement of the sprocket gear may be necessary to ensure the proper functioning and safety of the 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:
- Identify the Application Requirements: Understand the specific requirements of your application, including the desired speed, torque, power transmission, and operating conditions.
- 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.
- 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.
- 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.
- Verify Shaft Compatibility: Ensure that the sprocket gear’s bore size matches the diameter of your application’s input and output shafts.
- 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.
- Check Center Distance: Verify the center distance between the driving and driven sprockets to ensure proper chain or belt tension and alignment.
- Review Manufacturer Recommendations: Manufacturers often provide guidelines and specifications for their sprocket gears. Review their recommendations and consult with experts if necessary.
- 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.
