INSTALLATION AND USING
The chain wheel, 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.
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.

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 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
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 you ensure proper tensioning of a motor chain?
To ensure proper tensioning of a motor chain, the following steps can be followed:
1. Consult Manufacturer Guidelines:
Refer to the manufacturer’s guidelines and specifications for the specific motor chain being used. They often provide recommended tensioning values and procedures.
2. Check Initial Tension:
Ensure that the initial tension of the motor chain is set correctly during installation. This involves adjusting the tension to the manufacturer’s specifications based on the chain length and type.
3. Measure Deflection:
Measure the chain’s deflection to determine if it is within the recommended range. Deflection refers to the amount of vertical movement the chain has when pressure is applied at a specific point.
4. Use Tensioning Tools:
Utilize appropriate tensioning tools to adjust the tension of the motor chain accurately. These tools can help ensure consistent and accurate tensioning across the entire length of the chain.
5. Check Alignment:
Ensure that the motor chain is properly aligned with the sprockets and pulleys it interacts with. Misalignment can cause uneven tension distribution and lead to premature wear and potential failure.
6. Regular Inspection:
Regularly inspect the motor chain for any signs of excessive wear, stretching, or elongation. If any issues are identified, take appropriate action such as adjusting the tension or replacing the chain.
It is important to note that the proper tensioning of a motor chain is crucial for its reliable operation. Improper tension can lead to premature wear, increased noise, and reduced efficiency. Always follow the manufacturer’s recommendations and consult with experienced professionals if necessary.
Can a motor chain be used for high-speed applications?
Yes, motor chains can be used for high-speed applications depending on their design and specifications. Here are some factors to consider:
1. Chain Speed Rating: Motor chains are typically rated for specific maximum speeds. It is important to choose a motor chain that has a speed rating suitable for your application. Higher speed ratings indicate that the chain is designed to handle faster rotational speeds without compromising performance or safety.
2. Chain Design: Motor chains for high-speed applications are often designed with features to reduce friction and minimize the effects of centrifugal forces. This may include precision machining, specialized coatings, and optimized lubrication systems. These design considerations help maintain chain stability and performance at high speeds.
3. Lubrication: Proper lubrication is crucial for high-speed motor chain applications. It helps reduce friction, heat, and wear, ensuring smooth operation at elevated speeds. Selecting the appropriate lubricant and establishing a regular lubrication schedule are essential for maximizing the performance and lifespan of the motor chain.
4. Chain Tension: Maintaining proper chain tension is important for high-speed applications. Excessive slack or excessive tension can lead to performance issues, increased wear, and potential chain failure. It is necessary to follow the manufacturer’s guidelines for tensioning the motor chain and regularly check and adjust the tension as needed.
5. Sprocket Design: The design and quality of the sprockets that engage with the motor chain are also crucial for high-speed applications. High-speed sprockets should be precisely machined, balanced, and durable to ensure smooth and reliable power transmission.
It is important to consult the manufacturer’s specifications and guidelines when selecting a motor chain for high-speed applications. They can provide detailed information on the chain’s speed capabilities and any specific considerations for optimal performance at high speeds. By choosing the appropriate motor chain and implementing proper maintenance practices, it is possible to use motor chains effectively in high-speed applications.
What are the different types of motor chains available?
Motor chains come in various types, each designed to meet specific requirements of different applications. Here are some common types of motor chains:
1. Roller Chains: Roller chains are the most common type of motor chain. They consist of inner and outer plates connected by rollers. These chains are known for their high strength, durability, and ability to handle heavy loads. Roller chains are widely used in industries such as automotive, industrial machinery, and agriculture.
2. Silent Chains: Silent chains, also known as inverted-tooth chains, feature tooth-shaped plates that engage with each other. They provide smooth and quiet operation, making them suitable for applications requiring low noise levels. Silent chains are commonly used in precision machinery, printing presses, and automotive timing systems.
3. Leaf Chains: Leaf chains have flat, interlocking plates connected by pins. They are primarily used in lifting and hoisting applications, such as forklifts and cranes. Leaf chains are known for their high tensile strength and resistance to fatigue.
4. Conveyor Chains: Conveyor chains are specifically designed for conveying materials in conveyor systems. They feature large, wide plates to support the load and provide smooth movement. Conveyor chains are used in industries such as mining, food processing, and packaging.
5. Timing Chains: Timing chains are used in engines to synchronize the rotation of the crankshaft and camshaft. They have precise tooth profiles that ensure accurate timing of valve operation. Timing chains are commonly found in automotive engines and other internal combustion engines.
6. Specialty Chains: There are also specialized motor chains designed for specific applications. Examples include escalator chains, bicycle chains, motorcycle chains, and marine chains.
Motor chains are available in different sizes, materials, and configurations to suit specific requirements. It is important to select the appropriate chain type based on factors such as load capacity, speed, environment, and application-specific needs.
