Double Plus / Free Flow Chains

Double Plus Chains / Free Flow Chains

Double Plus Chains / Free Flow Chains are a type of roller chain that is commonly used in high-speed applications where accuracy and precision are essential. They are designed to provide superior performance and durability compared to standard roller chains. In this article, we will discuss the history, design, application, and maintenance of Double Plus chains.

Double Plus Chains / Free Flow Chains History:

The concept of roller chains dates back to the early 19th century when the first bicycle was invented. The bicycle chain was a simple roller chain that transmitted power from the pedals to the rear wheel. Over the years, roller chains have been improved and refined to meet the needs of various industries.

Double Plus chains were first developed in Japan in the 1960s by the Tsubakimoto Chain Company. They were initially used in the printing industry to transport paper through high-speed printing presses. Double Plus chains soon found applications in other industries, such as packaging, food, and automotive.

Double Plus Chains / Free Flow Chains Design:

Double Plus Chains / Free Flow Chains are similar in design to standard roller chains but have some key differences that make them more robust and durable. They consist of a series of links, each of which contains one or more rollers that rotate freely within the links. The links are connected by pins that allow the chain to articulate.

The rollers of a Double Plus chain are larger in diameter than those of a standard roller chain. This provides a greater contact area between the roller and the sprocket, resulting in less wear and longer life. The rollers are often made of high-quality steel or other materials that are resistant to wear and corrosion.

The links of a Double Plus chain have a unique shape, with two side plates that are joined by a centre plate. The centre plate has two holes that allow the pins to pass through, while the side plates are shaped like a figure-eight. This design provides a larger contact area between the sprocket teeth and the chain, resulting in smoother and more precise transmission of power.

Double Plus Chains / Free Flow Chains Application:

Double Plus Chains / Free Flow Chains are commonly used in high-speed applications where accuracy and precision are essential. They are often used in printing presses, packaging machines, and high-speed conveyor systems. Double Plus chains can transmit power with minimal noise and vibration, even at high speeds.

One of the advantages of Double Plus chains is their ability to maintain accuracy and precision over long periods of time. They have a low rate of elongation and wear, which means that they can maintain their pitch accuracy even after thousands of hours of operation. This makes Double Plus chains ideal for applications that require consistent and reliable performance.

Double Plus Chains / Free Flow Chains Maintenance:

Like any other mechanical component, Double Plus chains require regular maintenance to ensure optimal performance and longevity. The following are some tips for maintaining Double Plus chains:

1. Lubrication: Double Plus chains should be lubricated with a high-quality lubricant that is suitable for the operating conditions. The lubricant should be applied evenly and regularly to prevent wear and corrosion.

2. Tension: Double Plus chains should be tensioned properly to prevent slack and excessive wear. The tension should be adjusted according to the manufacturer's recommendations and the load capacity of the chain.

3. Inspection: Double Plus chains should be inspected regularly for signs of wear, corrosion, and damage. The rollers, links, and pins should be checked for cracks, dents, and deformations. Any worn or damaged components should be replaced immediately to prevent further damage.

4. Cleaning: Double Plus chains should be cleaned regularly to remove dirt, debris, and contaminants that can cause wear and corrosion. The chain should be cleaned with a soft brush and a mild detergent, and then rinsed with water and dried.

Double Plus Chains / Free Flow Chains Conclusion:

Double Plus chains are a specialized type of roller chain that is designed to provide superior performance and durability in high-speed applications. They are used in a variety of industries, including printing, packaging, and automotive. Proper maintenance is essential to ensure
