KONSTRUKCE ŘETĚZU

^{Dvě různé velikosti válečkových řetězů, znázorňující konstrukci.
There are two types of links alternating in the bush roller chain. The first type is inner links, having two inner plates held together by two sleeves or bushings upon which rotate two rollers. Inner links alternate with the CZPT type, the outer links, consisting of two 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 one 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 CZPT 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 CZPT as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

MAZÁNÍ

^{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 CZPT 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]}

Existuje také mnoho řetězů, které musí pracovat ve znečištěných podmínkách a z důvodu velikosti nebo provozu je nelze utěsnit. Příklady zahrnují řetězy na zemědělských strojích, jízdních kolech a motorových pilách. Tyto řetězy budou nutně mít relativně vysokou míru opotřebení, zejména pokud jsou obsluha připravena akceptovat větší tření, nižší účinnost, větší hluk a častější výměnu, protože zanedbává mazání a seřizování.

Many oil-based lubricants attract dirt and other particles, eventually forming an abrasive paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

MAZÁNÍ ŘETĚZŮ MOTOCYKLU

^{Řetězy pracující při vysokých rychlostech srovnatelných s těmi na motocyklech by se měly používat ve spojení s olejovou lázní. U moderních motocyklů to není možné a většina motocyklových řetězů běží nechráněná. Motocyklové řetězy se proto ve srovnání s jinými aplikacemi opotřebovávají velmi rychle. Jsou vystaveny extrémním silám a dešti, nečistotám, písku a posypové soli.}

Řetězy motocyklů jsou součástí hnacího ústrojí, které přenáší výkon motoru CZPT na zadní kolo. Správně mazané řetězy mohou v převodovce dosáhnout účinnosti 98% nebo vyšší. Nemazané řetězy výrazně snižují výkon a zvyšují opotřebení řetězu a řetězového kola.

Dva typy maziv pro aftermarket se používají k výrobě motocyklových řetězů: sprejová maziva a systémy kapacího podávání oleje.

Spray lubricants may contain wax or PTFE. While these lubricants use tack additives to stay on the chain they can also attract dirt and sand from the road and over time produce a grinding paste that accelerates component wear.
Systémy kapkového podávání oleje nepřetržitě mažou řetěz a používají lehký olej, který se k řetězu nelepí. Výzkum ukázal, že systémy kapkového podávání oleje poskytují největší ochranu proti opotřebení a největší úsporu času potřebného k údržbě.

VARIANTY DESIGN

^{Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
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 one 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 two rows of plates on the outer sides of the chain, there may be three (“duplex”), four (“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 CZPT ican National CZPT CZPT (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 one 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 CZPT 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.

POUŽITÍ

An example of two ‘ghost’ sprockets tensioning a triplex roller chain system
Válečkové řetězy se používají v nízkorychlostních až středněrychlostních pohonech při rychlosti okolo 180 až 240 metrů za minutu; při vyšších rychlostech, okolo 600 až 900 metrů za minutu, se však kvůli opotřebení a hlučnosti obvykle používají klínové řemeny.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
Velká většina automobilových motorů používá k pohonu vačkového hřídele (hřídelů) válečkové řetězy. Velmi výkonné motory často používají ozubený pohon a od začátku 60. let 20. století někteří výrobci používali ozubené řemeny.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Řetězy motorových pil se povrchně podobají válečkovým řetězům, ale jsou více příbuzné listovým řetězům. Jsou poháněny vyčnívajícími hnacími články, které slouží také k upevnění řetězu na liště.

Sea Harrier FA.2 ZA195 CZPT (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 CZPT , 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 forward flight, a system known as Thrust vectoring.

OPOTŘEBENÍ ŘETĚZŮ KOLA

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. CZPT dix 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.

PEVNOST ŘETĚZU

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. CZPT 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)^{[citace nutná]}. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)². X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Pro mnemotechnické účely je níže uvedena další prezentace klíčových rozměrů ze stejné normy, vyjádřených ve zlomcích palce (což bylo součástí úvah o volbě preferovaných čísel v normě ANSI):

Rozteč (palce)	Vyjádřená výška tónu v osminách	Standard ANSI číslo řetězu	Šířka (palce)
¹⁄₄	²⁄₈	25	¹⁄₈
³⁄₈	³⁄₈	35	³⁄₁₆
¹⁄₂	⁴⁄₈	41	¹⁄₄
¹⁄₂	⁴⁄₈	40	⁵⁄₁₆
⁵⁄₈	⁵⁄₈	50	³⁄₈
³⁄₄	⁶⁄₈	60	¹⁄₂
1	⁸⁄₈	80	⁵⁄₈

Poznámky:
1. Rozteč je vzdálenost mezi středy válečků. Šířka je vzdálenost mezi spojovacími deskami (tj. o něco větší než šířka válečku, aby se zajistila vůle).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. Levá číslice označuje počet osmin palce, které tvoří výšku tónu.
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 one 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.

Válečkové řetězy vyrobené podle normy ISO se někdy nazývají izocheiny.
