Bush-Roller-Chain

Roller chains are one of the most common and popular types of power transmission components. They are widely used in bicycles, motorcycles, personal mobility devices and various industrial equipment.

A typical chain consists of a number of plates arranged alternately and connected together by pins which pass through hardened steel bushes. These bushes are covered with rollers that contact the mating sprocket teeth and are held together by riveted pins.

Strength

Bush-roller-chains are used in many kinds of industrial machinery, such as conveyors, cars, motorcycles, bicycles, and so on. In order to maintain their operation, these chains must be able to resist wear and be strong against shock, fatigue and compression.

The strength of a chain can be measured in several ways, one of which is tensile strength. This is a rating that indicates the maximum force that a chain can withstand before it breaks.

Roller chains can also be tested for their fatigue strength, which is a measure of how strong the chain will be after continuous use over an extended period of time. This can be a more accurate measure of durability, as it takes into account a chain's one-time load capacity and its ability to withstand repeated stress over time.

In general, a roller chain can withstand loads of up to 1/9 its tensile strength for press-fit master links and up to 1/6 for slip-fit master links. However, a chain that is operated on a continuous drive over these thresholds may fail prematurely through linkplate fatigue failure.

Durability

The durability of bush-roller-chains is primarily determined by how well the parts are lubricated. Continuous, clean lubrication is important for efficient chain operation and proper tensioning.

In addition, a good quality chain should be heat treated to improve strength and wear resistance. Solid bushings are a better choice than split bushings for increased durability and service life.

Roller chains are essentially a series of alternating assembled roller links and pin links. They are available with single strands, or in multiple strands joined together by a common pin.

During sprocket engagement, the chain flexes around the pin and bush; therefore, both the pin and the bush need high tensile and shear strength, excellent bending resistance, shock resistance, and great wear resistance. They also need to have good endurance against repeated shock loads.

Noise

The most common type of chain drive for domestic, industrial and agricultural machinery is roller chain or bush-roller-chain. These chains consist of a series of short cylindrical rollers held together by side links, driven by a toothed wheel called a sprocket.

These chains can be noisy, especially when they are not properly maintained or have a lack of lubrication. The impact noise generated when the chain roller strikes the tooth bottom of the sprocket can be quite loud.

One solution to this problem is to use a plastic ring around the teeth of the sprocket that does not contact the chain roller or the tooth cavity. This allows the chain to enter the sprocket more slowly.

The impact noise is not just caused by the chain roller striking the tooth bottom of the sprocket but also by the interaction between the sprocket and its parts, such as the bushing or pin. With proper lubrication, these interactions can be minimized or eliminated entirely.

Weight

Roller chain, or bush-roller-chain, is a common type of power transmission chain used for industrial, agricultural, and domestic machinery. It is simple, reliable, and efficient (as much as 98% efficient under ideal conditions) but can be difficult to maintain.

It consists of a series of short cylindrical rollers held together by side links. These are driven by a toothed wheel called a sprocket.

The weight of a roller chain is determined by its pitch, which is the distance between roller centers; and its width, which is slightly wider than the roller width to allow for clearance. The standard number of the pitch is the right-hand digit, followed by an "H"; for example, 60H-3 denotes a 3/4 inch pitch heavyweight triple-strand chain.

There are two types of alternating bush-roller chains; inner links, consisting of two inner plates held together by sleeves or bushings upon which rotate two rollers, and outer links, consisting of two outer plates held together by pins passing through the bushings. Another type, the bushingless roller chain, resembles inner links but without separate bushings or sleeves; instead, the plate has a tube stamped into it protruding from the hole which serves the same purpose.
