链条的构造
两种不同尺寸的滚子链，展示其结构。
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.
润滑
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]
还有很多链条必须在肮脏的环境下运行，并且由于尺寸或操作原因无法密封。例如，农用设备、自行车和链锯上的链条。这些链条的磨损率必然相对较高，尤其是在操作人员忽视润滑和调整，从而导致摩擦力增大、效率降低、噪音增大以及更换频率增加的情况下。
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.
摩托车链条润滑
与摩托车链条一样高速运转的链条，应该配合油浴使用。但现代摩托车无法做到这一点，大多数摩托车链条都处于裸露状态。因此，与其他用途的链条相比，摩托车链条的磨损速度往往非常快。它们承受着巨大的力，并且会暴露在雨水、灰尘、沙子和道路盐分中。
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.
变体设计
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.

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.

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.
自行车链条磨损
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.
链强度
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)[需要引用]. 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).

为了便于记忆，下面是同一标准中关键尺寸的另一种表示方法，以英寸的分数表示（这也是 ANSI 标准中选择优选数字的思路之一）：
| 螺距（英寸） | 音调表达 八分之一 | ANSI标准 链号 | 宽度（英寸） |
|---|---|---|---|
| 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 |
笔记：
1. 节距是指滚子中心之间的距离。宽度是指连接板之间的距离（即略大于滚子宽度，以留出间隙）。
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. 左边的数字表示构成音高的八分之一英寸的数量。
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.
采用 ISO 标准制造的滚子链有时被称为等轴链。

电机链条可以在高温高湿环境下使用吗？
是的，电机链条可以在高温或高湿环境下使用，但需要考虑一些因素。
高温：
在高温环境下运行，选择能够承受高温的电机链条至关重要。高温应用链条通常采用特殊的耐热材料，例如热处理钢或合金。这些材料具有卓越的耐热性，即使在高温下也能保持其强度和性能。
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.
湿度：
在潮湿环境中，电机链条发生腐蚀和生锈的风险会增加。为了解决这个问题，电机链条通常采用耐腐蚀材料和涂层。不锈钢链条或带有特殊耐腐蚀涂层的链条能更好地抵御潮湿环境的影响。
在潮湿环境中，适当的维护和润滑至关重要，可以防止水分渗入链条并导致腐蚀。定期检查、清洁并使用防腐蚀润滑剂进行润滑，有助于延长链条的使用寿命并保持其性能。
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.
电机链条能承受重载吗？
是的，电机链条的设计旨在应对各种应用中的重载。以下是一些需要考虑的因素：
1. 链条强度：电机链条有不同的强度等级，通常以其最大允许拉力或断裂强度来衡量。选择电机链条时，务必根据应用中的预期负载选择合适的强度等级。强度等级越高的链条，可以承受更大的负载。
2. 链条材质：电机链条通常采用高强度钢或合金材料制成，具有优异的耐用性和承载能力。材质的选择取决于具体的应用需求，包括预期负载、环境条件以及任何相关法规标准。
3. 链条设计：专为重载应用设计的电机链条通常具有坚固的结构特征，以增强其承载能力。这些特征可能包括更大的节距、更厚的链板、硬化部件和精密制造工艺。这种设计确保链条能够承受重载带来的力和应力。
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. 链轮设计：与电机链条啮合的链轮在承受重载方面也起着至关重要的作用。链轮的设计应能将负载均匀地分布在链条上，并确保可靠的啮合。坚固耐用且尺寸合适的链轮可确保链条有效地传递重载，而不会过度磨损或发生故障。
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.
什么是电机链条？它是如何工作的？
电机链，又称动力传输链，是一种用于将电机或发动机的动力传递到机器或系统各个部件的机械装置。它由一系列相互连接的链节组成，形成一条柔韧耐用的链条。
电机链条广泛应用于汽车、工业机械、农业设备和输送系统等领域。它们在将电机产生的旋转运动和动力传递到车轮、齿轮、链轮或滑轮等不同部件的过程中发挥着至关重要的作用。
Here’s how a motor chain is typically used:
1. 动力传输：电机链的主要功能是将动力从电机传递到系统的其他部分。当电机旋转时，它驱动链条，链条进而驱动与之连接的部件，使它们能够执行其预期功能。
2. 速度和扭矩转换：电机链条的设计目的是以不同的速度传递动力，并转换电机与被驱动部件之间的扭矩。通过选择合适的链轮尺寸和链条长度，可以调节转速和扭矩，以满足系统需求。
3. 灵活性和适应性：电机链条具有灵活性和适应性，可用于各种方向和配置。它们能够适应错位、不均匀负载和方向变化，因此适用于复杂的机械和系统。
4. 维护和润滑：正确的维护和润滑对于电机链条的可靠运行至关重要。定期检查、清洁和润滑有助于减少摩擦、磨损和腐蚀，从而确保链条的最佳性能和使用寿命。
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.
