KONSTRUKCIJA LANCA
Dvije različite veličine valjkastih lanaca, koje prikazuju konstrukciju.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
PODMAZIVANJE
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
Također postoje mnogi lanci koji moraju raditi u prljavim uvjetima i zbog veličine ili operativnih razloga ne mogu se zatvoriti. Primjeri uključuju lance na poljoprivrednoj opremi, biciklima i motornim pilama. Ovi lanci će nužno imati relativno visoke stope trošenja, posebno kada su operateri spremni prihvatiti veće trenje, manju efikasnost, više buke i češću zamjenu jer zanemaruju podmazivanje i podešavanje.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a CHINAMFG film after application and repels both particles and moisture.
PODMAZIVANJE LANCA MOTOCIKLA
Lanci koji rade pri velikim brzinama usporedivim s onima na motociklima trebaju se koristiti zajedno s uljnom kupkom. Za moderne motocikle to nije moguće, a većina lanaca za motocikle radi nezaštićeno. Stoga se lanci za motocikle vrlo brzo troše u odnosu na druge primjene. Izloženi su ekstremnim silama i kiši, prljavštini, pijesku i soli za snijeg.
Motorcycle chains are part of the drive train to transmit the motor power to the back wheel. Properly lubricated chains can reach an efficiency of 98% or greater in the transmission. Unlubricated chains will significantly decrease performance and increase chain and sprocket wear.
Two types of CHINAMFG lubricants are available for motorcycle chains: spray on lubricants and oil drip feed systems.
Maziva u spreju mogu sadržavati vosak ili PTFE. Iako ova maziva koriste aditive za lijepljenje kako bi ostala na lancu, ona također mogu privući prljavštinu i pijesak s ceste i vremenom stvoriti pastu za brušenje koja ubrzava trošenje komponenti.
Oil drip feed systems continuously lubricate the chain and use light oil that does not stick to the chain. Research has shown that oil drip feed systems provide the greatest wear protection and greatest power saving.
VARIJANTE DIZAJNA

If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
KORIŠTENJE

Valjkasti lanci se koriste u pogonima niske do srednje brzine pri brzinama od oko 180 do 240 metara u minuti; međutim, pri većim brzinama, oko 600 do 900 metara u minuti, obično se koriste klinasti remeni zbog habanja i problema s bukom.
Lanac za bicikl je oblik valjkastog lanca. Lanci za bicikle mogu imati glavnu kariku ili mogu zahtijevati alat za lanac za uklanjanje i ugradnju. Sličan, ali veći i stoga jači lanac koristi se na većini motocikala, iako se ponekad zamjenjuje zupčastim remenom ili osovinskim pogonom, koji nude niži nivo buke i manje zahtjeva za održavanjem.
Velika većina automobilskih motora koristi valjkaste lance za pogon bregaste osovine (osovina). Vrlo visokoperformansni motori često koriste zupčasti pogon, a počevši od ranih 1960-ih, neki proizvođači su počeli koristiti zupčaste remene.
Lanci se također koriste u viljuškarima koji koriste hidraulične klipove kao remenicu za podizanje i spuštanje kolica; međutim, ovi lanci se ne smatraju valjkastim lancima, već se klasificiraju kao lanci za podizanje ili lisnati lanci.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.
Sea Harrier FA.2 ZA195 front (cold) vector thrust nozzle – the nozzle is rotated by a chain drive from an air motor
A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
TROŠENJE LANCA BICIKLISTIKA
The lightweight chain of a bicycle with derailleur gears can snap (or rather, come apart at the side-plates, since it is normal for the “riveting” to fail first) because the pins inside are not cylindrical, they are barrel-shaped. Contact between the pin and the bushing is not the regular line, but a point which allows the chain’s pins to work its way through the bushing, and finally the roller, ultimately causing the chain to snap. This form of construction is necessary because the gear-changing action of this form of transmission requires the chain to both bend sideways and to twist, but this can occur with the flexibility of such a narrow chain and relatively large free lengths on a bicycle.
Chain failure is much less of a problem on hub-geared systems (e.g. Bendix 2-speed, Sturmey-Archer AW) since the parallel pins have a much bigger wearing surface in contact with the bush. The hub-gear system also allows complete enclosure, a great aid to lubrication and protection from grit.
ČVRSTOĆA LANCA
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[potreban citat]Valjkasti lanci koji rade na kontinuiranom pogonu izvan ovih pragova mogu i obično prerano otkazati zbog zamora spojnih ploča.

Za mnemoničke svrhe, u nastavku je još jedan prikaz ključnih dimenzija iz istog standarda, izraženih u dijelovima inča (što je bio dio razmišljanja iza izbora preferiranih brojeva u ANSI standardu):
| Razmak (inči) | Izražena visina tona u osminama | ANSI standard broj lanca | Širina (inči) |

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Napomene:
1. Korak je udaljenost između središta valjaka. Širina je udaljenost između spojnih ploča (tj. nešto veća od širine valjka kako bi se omogućio zazor).
2. Desna cifra standarda označava 0 = normalan lanac, 1 = lagani lanac, 5 = lanac bez valjaka s čahurama.
3. Lijeva cifra označava broj osmina inča koje čine visinu tona.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Valjkasti lanci izrađeni prema ISO standardu ponekad se nazivaju izolanci.

Može li se motorni lanac koristiti u okruženjima s visokim temperaturama ili vlagom?
Da, motorni lanci se mogu koristiti u okruženjima s visokim temperaturama ili vlagom, ali je potrebno uzeti u obzir određene faktore.
Visoke temperature:
Prilikom rada u okruženjima s visokim temperaturama, važno je odabrati motorni lanac koji može izdržati povišene temperature. Specijalni materijali otporni na toplinu, poput termički obrađenog čelika ili legura, često se koriste za konstrukciju lanaca namijenjenih za primjenu na visokim temperaturama. Ovi materijali imaju vrhunsku otpornost na toplinu i mogu održati svoju čvrstoću i performanse čak i na povišenim temperaturama.
In addition to selecting the appropriate chain material, proper lubrication becomes even more critical in high-temperature environments. The lubricant used should have a high temperature rating to ensure adequate lubrication and prevent premature wear. Regular monitoring of the chain’s condition and lubrication levels is essential to maintain its performance and minimize the effects of heat.
Vlažnost:
U vlažnim okruženjima povećava se rizik od korozije i stvaranja hrđe na lancu motora. Da bi se to riješilo, za lance motora se obično koriste materijali i premazi otporni na koroziju. Lanci od nehrđajućeg čelika ili lanci sa posebnim premazima otpornim na koroziju pružaju bolju zaštitu od vlage.
Pravilno održavanje i podmazivanje su također ključni u vlažnim okruženjima kako bi se spriječilo prodiranje vlage u lanac i izazivanje korozije. Redovne inspekcije, čišćenje i podmazivanje mazivima koja sprječavaju koroziju mogu pomoći u produženju vijeka trajanja lanca i održavanju njegovih performansi.
It is important to note that while motor chains can be used in high-temperature or humid environments, their performance and lifespan can still be affected. It is recommended to consult the chain manufacturer for specific guidelines and recommendations regarding the use of motor chains in such conditions. Additionally, proper ventilation and environmental controls should be considered to minimize the impact of high temperatures or humidity on the chain’s performance.
Može li motorni lanac podnijeti teška opterećenja?
Da, motorni lanci su dizajnirani za rukovanje teškim opterećenjima u različitim primjenama. Evo nekoliko faktora koje treba uzeti u obzir:
1. Čvrstoća lanca: Motorni lanci dostupni su u različitim stupnjevima čvrstoće, obično mjerenim u smislu njihove maksimalne dozvoljene napetosti ili prekidne čvrstoće. Važno je odabrati motorni lanac s stupnjem čvrstoće prikladnim za predviđena opterećenja u vašoj primjeni. Lanci s većim stupnjevima čvrstoće mogu podnijeti veća opterećenja.
2. Materijal lanca: Motorni lanci se obično izrađuju od visokočvrstog čelika ili legura koje pružaju odličnu izdržljivost i nosivost. Izbor materijala zavisi od specifičnih zahtjeva primjene, uključujući očekivano opterećenje, uslove okoline i sve regulatorne standarde.
3. Dizajn lanca: Motorni lanci dizajnirani za primjene s velikim opterećenjima često imaju robusne konstrukcijske karakteristike kako bi se poboljšala njihova sposobnost podnošenja opterećenja. To može uključivati veće veličine koraka, deblje ploče, kaljene komponente i preciznu proizvodnju. Dizajn osigurava da lanac može izdržati sile i naprezanja povezana s velikim opterećenjima.
4. Lubrication: Proper lubrication is essential for motor chains handling heavy loads. It helps reduce friction and wear, ensuring smooth operation and extending the chain’s service life. Adequate lubrication also prevents overheating and corrosion, which can negatively impact the chain’s load-carrying capacity.
5. Dizajn lančanika: Lančanici koji se spajaju s lancem motora također igraju ključnu ulogu u rukovanju teškim teretima. Lančanici trebaju biti dizajnirani tako da ravnomjerno raspoređuju opterećenje po lancu i osiguravaju pouzdano spajanje. Robusni i pravilno dimenzionirani lančanici osiguravaju da lanac može efikasno prenositi teška opterećenja bez prekomjernog habanja ili kvara.
When considering a motor chain for heavy-load applications, it is important to consult the manufacturer’s specifications and guidelines. They can provide detailed information on the chain’s load-carrying capacity, including factors such as tensile strength, working load limits, and recommended safety factors. Proper chain selection, regular maintenance, and adherence to load limitations are key to ensuring safe and efficient operation under heavy loads.
Šta je motorni lanac i kako se koristi?
Motorni lanac, također poznat kao lanac za prijenos snage, je mehanički uređaj koji se koristi za prijenos snage s motora na različite dijelove mašine ili sistema. Sastoji se od niza međusobno povezanih karika koje formiraju fleksibilan i izdržljiv lanac.
Lanci za motore se često koriste u širokom spektru primjena, uključujući automobilsku industriju, industrijske mašine, poljoprivrednu opremu i transportne sisteme. Oni igraju vitalnu ulogu u prenosu rotacionog kretanja i snage sa motora na različite komponente kao što su točkovi, zupčanici, lančanici ili remenice.
Here’s how a motor chain is typically used:
1. Prijenos snage: Primarna funkcija motornog lanca je prijenos snage s motora na druge dijelove sistema. Kada se motor okreće, on pokreće lanac, koji zauzvrat pokreće povezane komponente, omogućavajući im da obavljaju svoje predviđene funkcije.
2. Pretvaranje brzine i obrtnog momenta: Lanci motora su dizajnirani za prenos snage pri različitim brzinama i pretvaranje obrtnog momenta između motora i pogonjenih komponenti. Odabirom odgovarajućih veličina lančanika i dužine lanca, brzina rotacije i obrtni moment mogu se podesiti kako bi odgovarali zahtjevima sistema.
3. Fleksibilnost i prilagodljivost: Motorni lanci su fleksibilni i prilagodljivi, što im omogućava upotrebu u različitim orijentacijama i konfiguracijama. Mogu podnijeti neusklađenost, neravnomjerna opterećenja i promjene smjera, što ih čini pogodnim za složene mašine i sisteme.
4. Održavanje i podmazivanje: Pravilno održavanje i podmazivanje su neophodni za pouzdan rad motornih lanaca. Redovni pregled, čišćenje i podmazivanje pomažu u smanjenju trenja, habanja i korozije, osiguravajući optimalne performanse i dugovječnost lanca.
Motor chains come in different sizes, designs, and materials to suit specific applications. Selecting the right chain for a particular system involves considering factors such as load capacity, speed, environment, and compatibility with other components. It is important to follow the manufacturer’s guidelines and industry standards to ensure safe and efficient operation.
