CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
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.
LUBRICATION
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]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
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.
MOTORCYCLE CHAIN LUBRICATION
Chains operating at high speeds comparable to those on motorcycles should be used in conjunction with an oil bath. For modern motorcycles this is not possible, and most motorcycle chains run unprotected. Thus, motorcycle chains tend to wear very quickly relative to other applications. They are subject to extreme forces and are exposed to rain, dirt, sand and road salt.
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.
VARIANTS 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.
USE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
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.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
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.
BICYCLE CHAIN WEAR
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.
CHAIN STRENGTH
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)[citation needed]. 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.

À des fins mnémotechniques, voici une autre présentation des dimensions clés de la même norme, exprimées en fractions de pouce (ce qui faisait partie du raisonnement derrière le choix des nombres privilégiés dans la norme ANSI) :
| Pas (pouces) | Hauteur exprimée en huitièmes | norme ANSI numéro de chaîne | Largeur (pouces) |
|---|---|---|---|
| 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 |
Remarques :
1. Le pas correspond à la distance entre les centres des rouleaux. La largeur correspond à la distance entre les plaques de liaison (c'est-à-dire légèrement supérieure à la largeur des rouleaux pour permettre le dégagement).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. Le chiffre de gauche indique le nombre de huitièmes de pouce qui composent le pas.
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.
Les chaînes à rouleaux fabriquées selon la norme ISO sont parfois appelées chaînes isochrones.

Une chaîne de moteur peut-elle être utilisée dans des environnements à températures ou humidité élevées ?
Oui, les chaînes de moteur peuvent être utilisées dans des environnements à températures ou humidité élevées, mais certaines considérations doivent être prises en compte.
Températures élevées :
Lorsqu'il est utilisé dans des environnements à haute température, il est essentiel de choisir une chaîne de transmission capable de résister à ces températures élevées. Des matériaux spéciaux résistants à la chaleur, tels que l'acier traité thermiquement ou les alliages, sont souvent employés pour la fabrication des chaînes destinées aux applications à haute température. Ces matériaux offrent une résistance thermique supérieure et conservent leur robustesse et leurs performances même à des températures élevées.
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.
Humidité:
En milieu humide, le risque de corrosion et de formation de rouille sur la chaîne de transmission augmente. Pour y remédier, on utilise couramment des matériaux et des revêtements anticorrosion. Les chaînes en acier inoxydable ou celles dotées de revêtements anticorrosion spéciaux offrent une meilleure protection contre l'humidité.
Un entretien et une lubrification adéquats sont essentiels en milieu humide pour empêcher l'humidité de pénétrer dans la chaîne et de provoquer de la corrosion. Des inspections régulières, un nettoyage et une lubrification avec des lubrifiants anticorrosion contribuent à prolonger la durée de vie de la chaîne et à maintenir ses performances.
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.
Une chaîne de moteur peut-elle supporter de lourdes charges ?
Oui, les chaînes de moteurs sont conçues pour supporter des charges importantes dans diverses applications. Voici quelques facteurs à prendre en compte :
1. Résistance de la chaîne : Les chaînes de moteur sont disponibles en différents niveaux de résistance, généralement mesurés en termes de tension maximale admissible ou de résistance à la rupture. Il est important de choisir une chaîne de moteur dont la résistance est adaptée aux charges prévues pour votre application. Les chaînes de résistance plus élevée peuvent supporter des charges plus importantes.
2. Matériau de la chaîne : Les chaînes de moteurs sont généralement fabriquées en acier haute résistance ou en alliages qui offrent une excellente durabilité et une capacité de charge élevée. Le choix du matériau dépend des exigences spécifiques de l’application, notamment la charge prévue, les conditions environnementales et les normes réglementaires applicables.
3. Conception de la chaîne : Les chaînes de moteurs conçues pour les applications à forte charge présentent souvent une construction robuste afin d’optimiser leur capacité de charge. Celle-ci peut inclure un pas plus important, des maillons plus épais, des composants trempés et une fabrication de précision. Cette conception garantit que la chaîne peut résister aux forces et aux contraintes liées aux charges élevées.
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. Conception des pignons : Les pignons qui s’engrènent avec la chaîne du moteur jouent un rôle crucial dans la gestion des charges importantes. Ils doivent être conçus pour répartir uniformément la charge sur la chaîne et assurer un engrènement fiable. Des pignons robustes et de dimensions appropriées garantissent une transmission efficace des charges importantes par la chaîne, sans usure excessive ni rupture.
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.
Qu'est-ce qu'une chaîne de moteur et comment est-elle utilisée ?
Une chaîne de transmission, également appelée chaîne de motorisation, est un dispositif mécanique servant à transmettre la puissance d'un moteur à différentes parties d'une machine ou d'un système. Elle se compose d'une série de maillons interconnectés formant une chaîne flexible et résistante.
Les chaînes de transmission sont couramment utilisées dans de nombreuses applications, notamment dans les secteurs de l'automobile, des machines industrielles, des équipements agricoles et des systèmes de convoyage. Elles jouent un rôle essentiel dans la transmission du mouvement de rotation et de la puissance du moteur à différents composants tels que les roues, les engrenages, les pignons ou les poulies.
Here’s how a motor chain is typically used:
1. Transmission de puissance : La fonction principale d’une chaîne cinématique est de transmettre la puissance du moteur aux autres parties du système. Lorsque le moteur tourne, il entraîne la chaîne, qui à son tour actionne les composants reliés, leur permettant ainsi de remplir leurs fonctions.
2. Conversion de vitesse et de couple : Les chaînes de transmission sont conçues pour transmettre la puissance à différentes vitesses et convertir le couple entre le moteur et les composants entraînés. En choisissant des pignons et des chaînes de tailles appropriées, la vitesse de rotation et le couple peuvent être ajustés aux besoins du système.
3. Flexibilité et adaptabilité : Les chaînes motrices sont flexibles et adaptables, ce qui permet de les utiliser dans diverses orientations et configurations. Elles peuvent compenser les défauts d’alignement, les charges inégales et les changements de direction, ce qui les rend adaptées aux machines et systèmes complexes.
4. Entretien et lubrification : Un entretien et une lubrification appropriés sont essentiels au bon fonctionnement des chaînes de moteur. L’inspection, le nettoyage et la lubrification réguliers contribuent à réduire la friction, l’usure et la corrosion, garantissant ainsi des performances optimales et une longue durée de vie à la chaîne.
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.
