KÆDEKONSTRUKTION
To forskellige størrelser rullekæde, der viser konstruktionen.
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.
SMØRING
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]
Der er også mange kæder, der skal fungere under snavsede forhold, og som af størrelses- eller driftsmæssige årsager ikke kan forsegles. Eksempler inkluderer kæder på landbrugsudstyr, cykler og motorsave. Disse kæder vil nødvendigvis have relativt høj slidrate, især når operatørerne er parate til at acceptere mere friktion, mindre effektivitet, mere støj og hyppigere udskiftning, da de forsømmer smøring og justering.
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.
SMØRING AF MOTORCYKELS KÆDE
Kæder, der kører ved høje hastigheder svarende til dem på motorcykler, bør bruges sammen med et oliebad. For moderne motorcykler er dette ikke muligt, og de fleste motorcykelkæder kører ubeskyttet. Derfor har motorcykelkæder en tendens til at slides meget hurtigt i forhold til andre anvendelser. De er udsat for ekstreme kræfter og udsættes for regn, snavs, sand og vejsalt.
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.
VARIANTER 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 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.
BRUGE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Rullekæder bruges i drev med lav til mellem hastighed ved omkring 180 til 240 meter i minuttet; ved højere hastigheder, omkring 600 til 900 meter i minuttet, bruges der dog normalt kileremme på grund af slid- og støjproblemer.
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.
Langt de fleste bilmotorer bruger rullekæder til at drive knastakslen/knastakslerne. Meget højtydende motorer bruger ofte tandhjulstræk, og fra begyndelsen af 1960'erne blev tandremme brugt af nogle producenter.
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.
CYKELKÆDE SLIDTAGE
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.
KÆDE STYRKE
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)[kildehenvisning nødvendig]. 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.

Til huskeregler er nedenfor en anden præsentation af nøgledimensioner fra samme standard, udtrykt i brøkdele af en tomme (hvilket var en del af tanken bag valget af foretrukne tal i ANSI-standarden):
| Hældning (tommer) | Udtrykt tonehøjde i ottendedele | ANSI-standard kædenummer | Bredde (tommer) |
|---|---|---|---|
| 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 |
Noter:
1. Stigningen er afstanden mellem rullernes centre. Bredden er afstanden mellem ledpladerne (dvs. lidt mere end rullens bredde for at give plads til frigang).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. Det venstre ciffer angiver antallet af ottendedele af en tomme, der udgør tonehøjden.
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.
Rullekæder fremstillet efter ISO-standarden kaldes undertiden isokæder.

Kan en motorkæde bruges i miljøer med høje temperaturer eller luftfugtighed?
Ja, motorkæder kan bruges i miljøer med høje temperaturer eller luftfugtighed, men visse overvejelser skal tages i betragtning.
Høje temperaturer:
Ved drift i miljøer med høje temperaturer er det vigtigt at vælge en motorkæde, der kan modstå de forhøjede temperaturer. Specielle varmebestandige materialer, såsom varmebehandlet stål eller legeringer, anvendes ofte til konstruktion af kæder beregnet til højtemperaturanvendelser. Disse materialer har overlegen varmebestandighed og kan bevare deres styrke og ydeevne selv ved forhøjede temperaturer.
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.
Fugtighed:
I fugtige miljøer øges risikoen for korrosion og rustdannelse på motorkæden. For at imødegå dette anvendes der almindeligvis korrosionsbestandige materialer og belægninger til motorkæder. Kæder i rustfrit stål eller kæder med specielle korrosionsbestandige belægninger giver bedre beskyttelse mod fugt og luftfugtighed.
Korrekt vedligeholdelse og smøring er også afgørende i fugtige miljøer for at forhindre fugt i at trænge ind i kæden og forårsage korrosion. Regelmæssige inspektioner, rengøring og smøring med korrosionshæmmende smøremidler kan bidrage til at forlænge kædens levetid og opretholde dens ydeevne.
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.
Kan en motorkæde klare tunge belastninger?
Ja, motorkæder er designet til at håndtere tunge belastninger i forskellige applikationer. Her er nogle faktorer at overveje:
1. Kædestyrke: Motorkæder fås i forskellige styrkeklassificeringer, typisk målt i forhold til deres maksimalt tilladte spænding eller brudstyrke. Det er vigtigt at vælge en motorkæde med en styrkeklassificering, der er egnet til de forventede belastninger i din applikation. Kæder med højere styrkeklassificeringer kan håndtere tungere belastninger.
2. Kædemateriale: Motorkæder er almindeligvis lavet af højstyrkestål eller legeringsmaterialer, der giver fremragende holdbarhed og bæreevne. Valget af materiale afhænger af de specifikke anvendelseskrav, herunder den forventede belastning, miljøforhold og eventuelle lovgivningsmæssige standarder.
3. Kædedesign: Motorkæder designet til tunge belastninger har ofte robuste konstruktionsfunktioner for at forbedre deres lastbærende egenskaber. Disse kan omfatte større stigninger, tykkere plader, hærdede komponenter og præcisionsfremstilling. Designet sikrer, at kæden kan modstå de kræfter og belastninger, der er forbundet med tunge belastninger.
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. Tandhjulsdesign: Tandhjulene, der griber ind i motorkæden, spiller også en afgørende rolle i håndteringen af tunge belastninger. Tandhjulene bør være designet til at fordele belastningen jævnt over kæden og give pålideligt indgreb. Robuste og korrekt dimensionerede tandhjul sikrer, at kæden effektivt kan overføre de tunge belastninger uden overdreven slitage eller svigt.
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.
Hvad er en motorkæde, og hvordan bruges den?
En motorkæde, også kendt som en kraftoverføringskæde, er en mekanisk enhed, der bruges til at overføre kraft fra en motor til forskellige dele af en maskine eller et system. Den består af en række sammenkoblede led, der danner en fleksibel og holdbar kæde.
Motorkæder bruges almindeligvis i en bred vifte af applikationer, herunder bilindustrien, industrimaskiner, landbrugsudstyr og transportbåndssystemer. De spiller en afgørende rolle i at overføre rotationsbevægelse og kraft fra motoren til forskellige komponenter såsom hjul, gear, tandhjul eller remskiver.
Here’s how a motor chain is typically used:
1. Kraftoverførsel: En motorkædes primære funktion er at overføre kraft fra motoren til andre dele af systemet. Når motoren roterer, driver den kæden, som igen driver de tilsluttede komponenter, så de kan udføre deres tilsigtede funktioner.
2. Hastigheds- og momentkonvertering: Motorkæder er designet til at overføre effekt ved forskellige hastigheder og konvertere momentet mellem motoren og de drevne komponenter. Ved at vælge passende tandhjulsstørrelser og kædelængder kan rotationshastigheden og momentet justeres, så det passer til systemets krav.
3. Fleksibilitet og tilpasningsevne: Motorkæder er fleksible og tilpasningsdygtige, hvilket gør dem i stand til at blive brugt i forskellige retninger og konfigurationer. De kan håndtere skævheder, ujævne belastninger og retningsændringer, hvilket gør dem velegnede til komplekse maskiner og systemer.
4. Vedligeholdelse og smøring: Korrekt vedligeholdelse og smøring er afgørende for pålidelig drift af motorkæder. Regelmæssig inspektion, rengøring og smøring hjælper med at reducere friktion, slid og korrosion, hvilket sikrer optimal ydeevne og levetid for kæden.
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.
