Leaf Chain manufacturer introduced roller chain is a type of chain used to transfer mechanical power, is a type of chain drive, widely used in household, industrial and agricultural machinery, including conveyors, plotters, printing machines, automobiles, motorcycles Cars and bicycles. It is connected by a series of short cylindrical rollers and driven by a gear called a sprocket. It is a simple, reliable, and efficient power transmission device.

Roller chain can be made into single-row chain and multi-row chain. When it is necessary to bear a larger load and transfer larger power, a multi-row chain can be used, as shown in the figure. Multi-row chains are equivalent to several ordinary single-row chains connected by long pins, and their load-bearing capacity is proportional to the number of rows, but the more rows, the more difficult it is to make each row uniformly stressed, so the number of rows Should not be too much, commonly used are double-row chain and triple-row chain.

Roller chain transmission advantages: Compared with belt transmission, there is no elastic sliding, which can maintain an accurate average transmission ratio and high transmission efficiency; the chain does not require large tension, so the load on the shaft and bearing is small; Slip, reliable transmission, strong overload capacity, can work well under low speed and heavy load. Disadvantages: Both the instantaneous chain speed and the instantaneous transmission ratio are changed, the transmission stability is poor, there are shocks and noise in the work, it is not suitable for high-speed occasions, and it is not suitable for the case where the direction of rotation changes frequently.

The length of the roller chain is expressed by the number of links. The number of chain links is preferably an even number, so that when the chains form a ring, the outer chain plate and the inner chain plate are connected, and the joint can be locked with a spring clip or a cotter pin. If the number of roller chain links is odd, a transition link is required. When the chain is under tension, the transition link also bears additional bending load, which should generally be avoided.

The roller chain effectively transmits power because it does not slip. The speed ratio is fixed and the absolute speed ratio. The efficiency of the roller chain is 98%. Under good lubrication, the efficiency of any load is quite good. This efficiency can be maintained throughout the life limit. The roller chain is versatile and can still operate effectively in harsh environments such as dirt, oil, and gas mixture. A single power source can drive multi-axis output at the same time, and the speed can be adjusted by the ratchet gear.

The roller chain absorbs vibration, and the chain itself is flexible, and when the oil film is stored in each part, it can protect the shaft and motor from impact force and strain. Light weight occupies a small space, the width is narrow, can be installed in a very small space, and the unit occupies a small transmission horsepower. The roller chain is durable, because the load is shared by many teeth on the ratchet gear, and each single gear has a small force to ensure life.

The Industrial Chain manufacturer summarized the above content, hoping to help you understand the basics of the chain.
