Ordinary Medium Link Chain

The ordinary medium link chain is a type of chain that consists of multiple interconnected links. Each link is connected by retaining members and has a pair of rollers at its ends that mate with pivots. The external link pivots on pivot 28, while the inner link pivots on auxiliary pivot 28. Auxiliary pivot pins are connected to the inner links by T-section posts 31 protruding from the frame 19.

Regular chains are typically made of low-grade carbon steel and come in various link sizes. They are commonly used in industrial, marine, and agricultural applications. These chains are available in unmarked and tested varieties, and they come in different link diameters and finishes, including yellow, blue, and galvanized.

A barbed chain is a type of ordinary long chain that consists of two side limb sections and a curved bridge. The two side limb sections meet at one end and cross at the other. The curved bridge section eliminates the need for welding, which helps reduce production costs.

Each link in a barbed chain is made from two separate side pieces connected by a U-shaped bridge section at their ends. The link ends at the point where the crossbar 60 projects in the opposite direction. Barbed chains are commonly used in agriculture and are called "barbed chains" because they have spikes on their edges that act as spikes when the chain spins behind a tractor.

What is the Strongest Link in a Chain?

The strength of a chain is determined by its weakest link. Each link in a chain has a different intensity, and if the weakest link breaks, the entire chain becomes useless. To test the strength of a chain, a single link is broken. If a chain contains 100 links and one of them is weak, the entire chain will be compromised. Standard grade chains can be enhanced for specific applications. For demanding maritime applications, heat-treated chains are used, such as tuna nets and scallop chains.

Thicker links are generally the strongest in a chain because they have no bending points. These chains are also more resistant to damage and can withstand greater exposure. Different types of chains, such as cable chains and wheat chains, have their own strengths and flexibility characteristics.

How to Design a Link Chain

Designing a link chain requires careful consideration of various factors. Here are some tips to help you select and design the perfect link chain for your needs.

1. Choose a chain made of durable material, preferably one that is resistant to wear and suitable for long-term use.

2. Consider the style and design of the chain. For example, a thin white gold chain may be less suitable for a statement necklace, while a chunky yellow gold chain can be perfect for a casual day. Paper clip chains are ideal for everyday office wear and casual attire.

3. Match the chain design to the garment or overall aesthetic. Classic mooring chains consist of small oval or circular links connected by welded circular links, while curb chains have clasps connecting the ends of the chain.

Related Sprockets

Properly installed sprockets play a vital role in increasing the efficiency and load-carrying capacity of chain-driven motion systems. When selecting a sprocket, it's important to consider the size and type of fit for your specific system.

Sprocket life can vary depending on factors such as riding style, conditions, chain pitch and size, and maintenance routine. Steel sprockets with hardened teeth can significantly increase their lifespan, often tripling it.

Sprockets are toothed wheels that mesh with a chain during rotation. They are commonly used in various applications, from bicycles to motor vehicles.
