Continue Roller chain and sketch roller chain, Leonardo da Vinci Roller Chain or Bush Roller Chain is the type of most commonly used to transmit mechanical energy on many types of domestic, industrial and agricultural machinery, including conveyors, wire and tube drawing machines, printing cars, cars, motorcycles and . It consists of a series of short cylindrical rollers held together by side links. It is controlled by a jagged wheel called a sproket. It is a simple, reliable and efficient means of transferring energy. Although Hans Rendold is credited with inventing a network of commercials in 1880, Leonardo da Vinci's sketches in the 16th century show a chain bearing the roller. The design of the chain Two different size roller chain, showing the design. There are two types of links alternating in the chain of rollers of the bush. The first type of internal bonds, which have two internal plates, held together by two sleeves or bushes on which two rollers rotate. Internal connections alternate with the second type, external links consisting of two external plates, held together by pins passing through the bushes of internal connections. The smart network of rollers is similar to the one used, though not in construction; Instead of individual bushes or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole that serves the same purpose. The advantage of this is to remove one step in the chain assembly. The design of the roller chain reduces friction compared to the simpler design, resulting in higher efficiency and less wear. Initial varieties of the energy chain lacked rollers and bushes, both internal and external plates, held by pins that were directly in contact with the teeth of the proquette; However, this configuration exhibited extremely quick wear both sprocket teeth, and plates where they are swivel on pins. This problem was partially solved by the development of artisanal chains, with pins holding external plates passing through bushes or sleeves connecting the inner plates. This spread the wear over a larger area; however the teeth of the were still worn faster than desirable, from sliding friction against bushings. Adding rollers surrounding the bush sleeve chain and provided rolling contact with teeth sprockets resulted in excellent resistance to wear both sprockets and chains as well. There is even a very low friction, as long as the chain is sufficiently smeared. Continuous, clean, lubricated roller chains is paramount for effective work as well as proper tension. (quote is necessary) Grease Many driving circuits (e.g. in factory equipment, or driving camshaft inside the internal combustion engine) work in a clean environment, and thus wearing surfaces (i.e., and bushes) are safe from precipitation and sand in the air, many even in airtight environments such as an oil bath. Some roller chains are designed for o-rings built into the space between the outer communication plate and the inner clip communication plate. Chain manufacturers began to include this feature in 1971 after the app was invented by Joseph Montano while working at the Whitney Chain in Hartford, Connecticut. O-rings have been incorporated as a way to improve the lubrication of power chain connections, a service that is vital to prolonging their working lives. These rubber fixtures form a barrier that keeps the plant from applying grease to the fat inside the pins and bush-wear areas. In addition, rubber o-rings prevent dirt and other contaminants from entering chain links where such particles could otherwise cause significant wear and tear. (quote is necessary) There are also many chains that have to work in dirty conditions, and for size or operational reasons can not be sealed. Examples include chains on agricultural equipment, bicycles and chain saws. These chains are sure to have relatively high wear and tear rates, especially when operators are willing to take more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and regulation. Many oil lubricants attract dirt and other particles, eventually forming an abrasive paste that will be a composite wear on the chains. This problem can be circumvented with the dry PTFE spray, which forms a strong film after application and repels both particles and moisture. Motorcycle chain lubricant Chains, working at high speeds comparable to motorcycles, should be used in conjunction with an oil bath. For modern motorcycles it is impossible, and most motorcycle chains operate without protection. Thus, motorcycle circuits tend to wear very fast compared to other applications. They are exposed to extreme forces and exposed to rain, mud, sand and road salt. Motorcycle circuits are part of the drive train to transfer engine power to the rear wheel. Properly oiled chains can achieve an efficiency of 98% or more in transmission. Unsnascated chains will significantly reduce performance and increase chain and proquette wear. For motorcycle chains are available two types of lubricants after-sales service: spray on lubricants and oil drip feed systems. Spray lubricants may contain wax or PTFE. While these lubricants use tack supplements to stay on the chain they can also draw dirt and sand off the road and over time produce grinding pastes that accelerates the wear of the components. (quote needed) Drip feed systems continuously lubricate the chain and use a light oil that does not stick to the chain. Studies have shown that drip feed oil systems provide the greatest protection of wear and energy. Options in Layout Layout Layout design Roller chain: 1. Outer plate, 2. Inner plate, 3. pin, 4. Bushing, 5. Roller If the chain is not used for the application of high wear (for example, if it simply transfers movement from the manual lever to the control shaft on the machine, or sliding door in the oven), then one of the simplest types of chain can still be used. Conversely, where additional strength is required, but a smooth drive of a smaller step, the chain can be siamesiated; instead of two rows of plates on the outside of the chain there may be three (duplex), four (triplex), or more rows of plates working in parallel, with bushings and rollers between each neighboring pair, and the same number of rows of teeth working parallel to sprockets to match. For example, synchronization chains on car engines tend to have multiple rows of plates called strands. The network of commercials is made in several sizes, the most common standards of the American Institute of National Standards (ANSI) are 40, 50, 60 and 80. The first digit (s) indicate the chain's pitch is eight inches, with the last digit 0 for the standard chain, 1 for the lightweight chain, and 5 for the bushy chain without rollers. Thus, a chain with a half-inch increment would be #40 while #160 teeth, dissociated 2 inches apart, etc. Metric resins are expressed in sixteen inches; thus, the #8 chain (08B-1) will be equivalent to the ANSI #40 chain. Most roller chains are made of plain carbon or alloy steel, but stainless steel is used in food processing machines or other places where lubricant is a problem, and nylon or brass is sometimes seen for the same reason. Roller chains are usually connected using a (also known as a link), which usually has one pin held by a forged clip rather than a friction fit, allowing it to be inserted or removed using simple tools. A chain with a removable reference or pin is also known as a snuff chain that allows you to adjust the length of the chain. Half of the links (also known as offsets) are available and used to increase the chain length with a single roller. The riveting roller chain has a master link (also known as a link) chained or mashed at the ends. These pins are made to be durable and are not removable. Используйте пример двух «призрачных» спрокетов, натяжающих тройную систему роликовых цепочек Roller, которые используются в низко- и средней скорости приводов со скоростью от 600 до 800 футов в минуту; However, at higher speeds, about 2,000 to 3,000 feet per minute, V-belts are usually used due to wear and noise issues. The chain is a form of roller chain. Bicycle chains may have a master link, or may need a chain tool to remove and install. Similar, but larger and therefore more The chain is used on most motorcycles, although sometimes it is replaced by either a serrated or a shaft drive that offer lower noise and less less Requirements. The vast majority of car engines use roller chains to drive camshaft (s). Very high performance engines often use drive , and since the early 1960s gear belts have been used by some manufacturers. Chains are also used in forklifts using hydraulic rams as a pulley to drive up and lower the wagon; however, these chains are not considered roller chains, but are classified as lifting or leaf chains. Chainsaw chains superficially resemble roller chains, but are more closely related to leaf chains. They are caused by the projection of drive links, which also serve to determine the location of the chain on the bar. Marine Harrier FA.2 -195 front (cold) snot thrust vector - the nozzle rotates chain drive from the air engine Possibly unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where the chain drive from the air engine is used to rotate the movable engine nozzle, allowing them to be directed downwards for flight hovering, or at the back for a normal front flight. Wear the wear effect on the roller chain is an increase in stride (distance links), causing the chain to grow longer. Note that this is due to wear on the turning pins and bushes, not from the actual metal stretching (as is the case with some flexible steel components such as the vehicle's handbrake). With modern chains it is unusual for a chain (except a bike) to wear until it breaks down, since a worn chain leads to a quick onset of wear on the teeth sprockets, with the ultimate failure being the loss of all teeth on the sprocket. Sprockets (particularly less than two) suffer grinding motion, which puts the characteristic shape of the hook into the controlled face of the teeth. (This effect is worsened by a chain that is incorrectly stretched but inevitable no matter what caution is not taken). Worn teeth (and chain) no longer provide a smooth transfer of energy, and this can become apparent from noise, vibration or (in car engines using a synchronization chain) the change in ignition time seen with the light of time. In these cases, both the sproquettes and the chain should be replaced, as the new chain on worn-out sproquettes will not last long. However, in less severe cases you can save more of the two sprockets, as it is always the smaller one that suffers the most wear and tear. Only in very light applications such as the bike, or in extreme cases of improper voltage, the chain tends to jump off the sprockets. Lengthening due to chain wear is calculated by the following formula: % ( ( ( S ( S ∗ P) / (S ∗ P) ∗ 100 ((M-(S-P)/ (S-P)) usually monitor the movement of chain tension (whether manual or or the exact length of the circuit drive (one of the rules is to replace the roller chain, which has an elongated 3% on an adjustable drive or 1.5% on a fixed center of disk). A simpler method, especially suitable for a loop or motorcycle user, is to try to pull the chain away from the larger of the two sprockets while ensuring the chain is tight. Any significant movement (such as being able to see through a gap) probably indicates a chain worn to the limit and beyond. Damage to Sprocket will result if the problem is ignored. Wear Sprocket cancels this effect and can mask chain wear. Bike chain wearing a light bike chain with gear can snap (or rather disperse on the side plates, as it is normal for riveting to fail in the first place) because the pins inside are not cylindrical, they barrel shape. The contact between pin and bushing is not an ordinary line, but a point that allows chain pins to pass through the bushes, and finally a roller, causing the chain to click. This form of design is necessary because the changing effect of this form of transmission requires the chain to bend sideways and spin, but this can happen with the flexibility of such a narrow chain and relatively large free lengths on the bike. Chain failure is much less of a problem on hub-directed systems (e.g. Bendix 2-speed, Sturmey-Archer AW), since parallel pins have much more wearing surface in contact with the bush. The hub system also allows a full body, a great help for lubrication and sand protection. The strength of the chain the most common measure of the strength of the roller chain is the strength of the awning. Tension force represents how much load the chain can withstand under a one-time load before breaking. No less important than strength is the power of chain fatigue. Critical factors of chain fatigue are the strength of the quality of steel used to produce the chain, the thermal treatment of chain components, the quality of the resin hole making linkplates, and the type of shot plus the intensity of the shot peen coating on the linkplates. Other factors may include the thickness of the link and the design (contour) of the link. The rule of thumb for a roller chain running on a continuous disk is that the chain load does not exceed only 1/6 or 1/9 of the strength of the chain, depending on the type of main links used (the press is suitable against the slip)... Roller circuits running on continuous drive outside these thresholds can and usually fail prematurely through linkplate fatigue failure. The standard minimum end strength of the ANSI 29.1 steel chain is 12,500 x (step, inches)2. The X-ring and O-Ring chains significantly reduce wear with internal lubricants, increasing the duration Chain. The inner lubricant is inserted using when riveting the chain together. Chain standards organizations (such as ANSI and ISO) maintain standards for the design, size, and interchangeability of transmission chains. For example, the following table shows data from the ANSI B29.1-2011 (Precision Power Transmission Roller Chains, Attachments and Sprockets) standard developed by the American Society of Mechanical Engineers (ASME).

Step distance between roller centers. Width is the distance between the communication plates (i.e. a little more than the width of the clearance roller). 2. The right digit of the standard means 0 - normal chain, 1 - light chain, 5 - chain for bushes without rollers. 3. The left digit indicates the number of eight inches that make up the field. 4. H after the standard number denotes a heavyweight circuit. The hyphenated number following the standard number means two-way (2), triple (3) and so on. Thus, 60H-3 denotes 60 heavyweight triple thread chain. A typical bike chain (for derailleur ) uses a narrow ⁄ a 1⁄2-inch chain. The width of the chain is variable and does not affect the payload capacity. The more sproquettes behind the rear wheel (historically 3-6, currently 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds at which they are designed to work, such as the 10 speed chain. Hub gears or single speed bikes use a 1/2 x 1/8 chain where 1/8 refers to the maximum thickness of the sprocket that can be used with a chain. Usually chains with parallel connections have quite a large number of links, with each narrow connection followed by a wide one. Chains built with a single type of connection, narrow at one and wide at the other end, can be made with an odd number of links, which can be an advantage to adapt to the special distance of the chain wheel; on the other hand, the chain is usually not as strong. Roller chains made according to the ISO standard are sometimes called isiches. See also self-smear chain Links b As much as 98% effective in ideal conditions, according to Kidd, Matt D.; N. E.
