KONŠTRUKCIA REŤAZE
Dve rôzne veľkosti valčekových reťazí, znázorňujúce konštrukciu.
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.
MAZANIE
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]
Existuje tiež veľa reťazí, ktoré musia pracovať v znečistených podmienkach a z dôvodu veľkosti alebo prevádzky ich nemožno utesniť. Medzi príklady patria reťaze na poľnohospodárskych strojoch, bicykloch a reťazových pílach. Tieto reťaze budú mať nevyhnutne relatívne vysokú mieru opotrebovania, najmä ak sú obsluha pripravená akceptovať väčšie trenie, nižšiu účinnosť, väčší hluk a častejšiu výmenu, pretože zanedbávajú mazanie a nastavovanie.
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.
MAZANIE REŤAZÍ MOTOCYKLOV
Reťaze pracujúce pri vysokých rýchlostiach porovnateľných s reťazami na motocykloch by sa mali používať v spojení s olejovým kúpeľom. Pri moderných motocykloch to nie je možné a väčšina motocyklových reťazí beží nechránená. Preto sa motocyklové reťaze v porovnaní s inými aplikáciami opotrebúvajú veľmi rýchlo. Sú vystavené extrémnym silám a dažďu, nečistotám, piesku a posypovej soli.
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.
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.
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.
VARIANTOVÝ DIZAJN
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 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.
POUŽITIE

Valčekové reťaze sa používajú v nízkorýchlostných až strednerýchlostných pohonoch pri rýchlostiach okolo 180 až 240 metrov za minútu; pri vyšších rýchlostiach, okolo 600 až 900 metrov za minútu, sa však kvôli opotrebovaniu a hluku zvyčajne používajú klinové remene.
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.
Prevažná väčšina automobilových motorov používa na pohon vačkového hriadeľa (hriadeľov) valčekové reťaze. Veľmi výkonné motory často používajú ozubený pohon a od začiatku 60. rokov 20. storočia niektorí výrobcovia používali ozubené remene.
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.
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.

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.
OPOTREBOVANIE REŤAZÍ BICYKLA
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.
PEVNOSŤ REŤAZE
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)[potrebný citát]. 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.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME).

Pre mnemotechnické účely je nižšie uvedená ďalšia prezentácia kľúčových rozmerov z tej istej normy, vyjadrených v zlomkoch palca (čo bolo súčasťou úvah o výbere preferovaných čísel v norme ANSI):
| Rozstup (palce) | Vyjadrená výška tónu v osminách | Norma ANSI číslo reťaze | Šírka (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. Rozstup je vzdialenosť medzi stredmi valčekov. Šírka je vzdialenosť medzi spojovacími doskami (t. j. o niečo väčšia ako šírka valčeka, aby sa zabezpečila vôľa).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. Ľavá číslica označuje počet osmín palca, ktoré tvoria rozstup tónov.
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.
Valčekové reťaze vyrobené podľa normy ISO sa niekedy nazývajú izorezaje.

Môže sa motorová reťaz používať v prostredí s vysokými teplotami alebo vlhkosťou?
Áno, motorové reťaze sa môžu používať v prostrediach s vysokými teplotami alebo vlhkosťou, ale je potrebné zvážiť určité faktory.
Vysoké teploty:
Pri prevádzke vo vysokoteplotnom prostredí je dôležité vybrať si motorovú reťaz, ktorá odolá zvýšeným teplotám. Na výrobu reťazí určených pre vysokoteplotné aplikácie sa často používajú špeciálne tepelne odolné materiály, ako je tepelne spracovaná oceľ alebo zliatiny. Tieto materiály majú vynikajúcu tepelnú odolnosť a dokážu si zachovať svoju pevnosť a výkon aj pri zvýšených teplotách.
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.
Vlhkosť:
Vo vlhkom prostredí sa zvyšuje riziko korózie a tvorby hrdze na motorovej reťazi. Na riešenie tohto problému sa na motorové reťaze bežne používajú materiály a nátery odolné voči korózii. Reťaze z nehrdzavejúcej ocele alebo reťaze so špeciálnymi nátermi odolnými voči korózii poskytujú lepšiu ochranu pred vlhkosťou.
Správna údržba a mazanie sú tiež dôležité vo vlhkom prostredí, aby sa zabránilo prenikaniu vlhkosti do reťaze a spôsobeniu korózie. Pravidelné kontroly, čistenie a mazanie mazivami inhibujúcimi koróziu môžu pomôcť predĺžiť životnosť reťaze a udržať jej výkon.
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.
Znesie motorová reťaz ťažké bremená?
Áno, motorové reťaze sú určené na zvládnutie ťažkých bremien v rôznych aplikáciách. Tu je niekoľko faktorov, ktoré treba zvážiť:
1. Pevnosť reťaze: Motorové reťaze sú dostupné v rôznych pevnostných hodnotách, zvyčajne meraných z hľadiska ich maximálneho povoleného napätia alebo pevnosti v pretrhnutí. Je dôležité vybrať motorovú reťaz s pevnosťou vhodnou pre predpokladané zaťaženie vo vašej aplikácii. Reťaze s vyššou pevnosťou znesú väčšie zaťaženie.
2. Materiál reťaze: Motorové reťaze sa bežne vyrábajú z vysokopevnostnej ocele alebo legovaných materiálov, ktoré poskytujú vynikajúcu odolnosť a nosnosť. Výber materiálu závisí od špecifických požiadaviek aplikácie vrátane očakávaného zaťaženia, podmienok prostredia a prípadných regulačných noriem.
3. Konštrukcia reťaze: Motorové reťaze určené pre aplikácie s vysokým zaťažením majú často robustné konštrukčné prvky, ktoré zvyšujú ich nosnosť. Môže ísť o väčšie rozstupy, hrubšie dosky, kalené komponenty a presnú výrobu. Konštrukcia zabezpečuje, že reťaz odolá silám a namáhaniu spojenému s vysokým zaťažením.
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. Konštrukcia ozubeného kolesa: Ozubené kolesá, ktoré sú v kontakte s reťazou motora, zohrávajú tiež kľúčovú úlohu pri manipulácii s ťažkými bremenami. Ozubené kolesá by mali byť navrhnuté tak, aby rovnomerne rozložili zaťaženie na reťaz a zabezpečili spoľahlivý záber. Robustné a správne dimenzované ozubené kolesá zabezpečujú, že reťaz dokáže efektívne prenášať ťažké bremená bez nadmerného opotrebenia alebo poruchy.
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.
Čo je motorová reťaz a ako sa používa?
Motorová reťaz, známa aj ako reťaz na prenos energie, je mechanické zariadenie používané na prenos energie z motora do rôznych častí stroja alebo systému. Pozostáva zo série vzájomne prepojených článkov, ktoré tvoria flexibilnú a odolnú reťaz.
Motorové reťaze sa bežne používajú v širokej škále aplikácií vrátane automobilového priemyslu, priemyselných strojov, poľnohospodárskych zariadení a dopravníkových systémov. Zohrávajú dôležitú úlohu pri prenose rotačného pohybu a výkonu z motora na rôzne komponenty, ako sú kolesá, ozubené kolesá, ozubené kolesá alebo remenice.
Here’s how a motor chain is typically used:
1. Prenos výkonu: Primárnou funkciou motorovej reťaze je prenos výkonu z motora do iných častí systému. Keď sa motor otáča, poháňa reťaz, ktorá následne poháňa pripojené komponenty, čo im umožňuje vykonávať ich určené funkcie.
2. Prevod rýchlosti a krútiaceho momentu: Reťaze motorov sú navrhnuté tak, aby prenášali výkon pri rôznych rýchlostiach a premieňali krútiaci moment medzi motorom a poháňanými komponentmi. Výberom vhodných veľkostí ozubených kolies a dĺžok reťazí je možné nastaviť rýchlosť otáčania a krútiaci moment tak, aby vyhovovali požiadavkám systému.
3. Flexibilita a prispôsobivosť: Motorové reťaze sú flexibilné a prispôsobivé, čo umožňuje ich použitie v rôznych orientáciách a konfiguráciách. Dokážu sa prispôsobiť nesúososti, nerovnomernému zaťaženiu a zmenám smeru, vďaka čomu sú vhodné pre zložité stroje a systémy.
4. Údržba a mazanie: Správna údržba a mazanie sú nevyhnutné pre spoľahlivú prevádzku motorových reťazí. Pravidelná kontrola, čistenie a mazanie pomáhajú znižovať trenie, opotrebovanie a koróziu, čím zabezpečujú optimálny výkon a dlhú životnosť reťaze.
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.
