ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission..

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.

Can a gear chain be used for vertical lifting applications?
Yes, a gear chain can be used for vertical lifting applications. However, certain factors need to be considered to ensure safe and efficient operation:
1. Load Capacity:
– Before using a gear chain for vertical lifting, it is essential to determine the load capacity requirements. The gear chain must be selected based on its rated load capacity to ensure it can safely lift the intended load.
2. Gear Chain Type:
– Not all gear chain types are suitable for vertical lifting applications. It is important to choose a gear chain specifically designed and rated for lifting loads vertically. These chains often feature special load-bearing components and mechanisms to handle the vertical forces.
3. Safety Features:
– Vertical lifting applications require additional safety features to prevent accidents or equipment failures. These may include safety brakes, overload protection devices, emergency stop systems, and fail-safe mechanisms. These safety features ensure the gear chain system can handle unexpected loads, prevent free-falling of the load, and provide emergency stopping capabilities.
4. Proper Installation and Maintenance:
– It is crucial to install the gear chain system correctly, following the manufacturer’s guidelines and industry standards. Regular maintenance and inspections are also necessary to identify any signs of wear, fatigue, or damage that could compromise the safety and performance of the gear chain.
5. Compliance with Regulations:
– When using a gear chain for vertical lifting, it is important to comply with applicable safety regulations and standards. These regulations may include requirements for load testing, documentation, operator training, and regular inspections by qualified personnel.
By considering the load capacity, selecting a suitable gear chain type, incorporating safety features, ensuring proper installation and maintenance, and complying with regulations, a gear chain can be used effectively and safely for vertical lifting applications.
What lubrication is recommended for a gear chain?
Proper lubrication is essential for the smooth and efficient operation of a gear chain. The lubricant used for a gear chain should have certain properties to ensure optimal performance and longevity. The following factors should be considered when selecting a lubricant for a gear chain:
1. Viscosity: The lubricant should have the appropriate viscosity to provide sufficient film thickness between the gear teeth and minimize friction and wear. The viscosity should be selected based on the operating conditions, such as speed, temperature, and load.
2. Extreme pressure (EP) additives: Gear chains often operate under high loads and pressures. The lubricant should contain EP additives that provide enhanced protection against metal-to-metal contact and prevent gear tooth damage.
3. Anti-wear properties: The lubricant should have excellent anti-wear properties to minimize wear on gear teeth and extend the chain’s service life. It should form a protective film on the surfaces to reduce friction and prevent metal-to-metal contact.
4. Corrosion protection: Gear chains may be exposed to moisture or corrosive environments. The lubricant should offer good corrosion protection to prevent rust and corrosion on the gear surfaces and chain components.
5. Compatibility: The lubricant should be compatible with the materials used in the gear chain, such as metals, plastics, or elastomers. It should not cause any adverse chemical reactions or damage to the chain components.
It is recommended to consult the gear chain manufacturer or a lubrication specialist to determine the specific lubricant requirements for your gear chain system. They can provide guidance on selecting the right lubricant based on the operating conditions, application requirements, and the type of gear chain used.
How do you select the right gear chain for your application?
When selecting the right gear chain for your application, there are several factors to consider. Here are some key considerations:
– Load and Power Requirements: Determine the maximum load and power requirements of your application. This will help you determine the size and strength of the gears and chain needed to handle the load and transmit the required power.
– Speed and Torque: Consider the operating speed and torque requirements of your application. Higher speeds and torque levels may require specific gear ratios and materials to ensure smooth and efficient operation.
– Environmental Conditions: Evaluate the environmental conditions in which the gear chain will operate. Factors such as temperature, moisture, dust, and chemicals can affect the performance and durability of the chain. Choose a gear chain that is suitable for the specific environment.
– Noise and Vibration: Consider the noise and vibration levels that are acceptable for your application. Some gear chains are designed to minimize noise and vibration, which may be important in certain applications.
– Efficiency and Precision: Depending on the application, you may require high efficiency and precise motion transmission. Consider gear chains that offer low backlash, high gear engagement efficiency, and accurate positioning capabilities.
– Maintenance and Lubrication: Assess the maintenance requirements and lubrication preferences of the gear chain. Some gear chains may require periodic lubrication or maintenance, while others may offer self-lubricating or maintenance-free options.
– Cost: Evaluate the cost of the gear chain, including initial purchase, installation, and maintenance expenses. Consider the long-term reliability and cost-effectiveness of the gear chain for your specific application.
By considering these factors and consulting with gear chain manufacturers or experts, you can select the right gear chain that meets the requirements of your application in terms of load capacity, speed, durability, precision, and cost-effectiveness.
