#Chain drive pdf basics series#
The silent chain also called inverted tooth chain, consists of a series of toothed link plates assembled on joint components in a way that allows free flexing between each pitch. Multiple-strand roller chains are used to provide increased power capacity without the need for increasing the chain pitch or its linear speed.The power rating capacities of these chains cover a wide range of drive load requirements. The most commonly used chain for drives is the single-strand standard series roller chain.These chains are generally smaller in diameter than the height of the link plates of the chain. the link plates serve as guides when the chain engages the sprockets,Ĭhains are also served as a guide to support material carried on it on tracks or ways, as is characteristic of conveyors and some bucket elevators. Roller chains are used for both drive and conveyor applications. It is a simple, reliable, and efficient for power transmission. It is driven by a toothed wheel called a sprocket. Roller chain consists of a series of short cylindrical rollers held together by side links. This t ype of chains is 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. Types of Chainsįrom an industry standpoint, the major types of chains are as follows: 1.
A silent chain is an inverted tooth chain which is extensively used for smooth and noiseless operations at low velocities. Roller chains are ones that are commonly used in bicycles, motorcycles, machine tools, etc. These include integral link chains, such as bar-link, flat-top, and welded steel chains, Offset link chains, which have all links alike.
Straight link chains, which have an alternate ‘outside’ and ‘inside’ links.
Regardless of the types of chains, their styles are classified as follows. Types of Chains Used in Power Transmission The sprockets are toothed wheels over which an endless chain is fitted. A chain drive consists of a chain and two wheels, called Sprockets. Chain drives are employed for a wide range of power transmission applications, like in bicycles, motorcycles, rolling mills, agricultural machinery, machine tools, conveyors, coal cutters, etc.
