两种不同尺寸的滚子链,展示其结构。
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.
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 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]
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 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.
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。
摩托车链条是传动系统的一部分,用于将发动机的动力传递到后轮。润滑良好的链条在传动系统中可达到 98% 或更高的效率。未润滑的链条会显著降低性能,并加剧链条和链轮的磨损。
摩托车链条的售后润滑剂有两种类型:喷涂式润滑剂和滴油式润滑系统。
喷雾润滑剂可能含有蜡或聚四氟乙烯(PTFE)。虽然这些润滑剂使用增粘剂使其能够附着在链条上,但它们也会吸附道路上的灰尘和沙粒,随着时间的推移,会产生研磨膏状物,加速部件磨损。
滴油式润滑系统持续润滑链条,并使用不会粘附在链条上的轻质润滑油。研究表明,滴油式润滑系统能提供最佳的磨损保护和最大的CZPT(链条磨损试验)节省。
变体设计
滚子链的组成结构:1. 外链板,2. 内链板,3. 销轴,4. 衬套,5. 滚子
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.
使用
两个“幽灵”链轮张紧三联滚子链系统的示例
滚子链用于每分钟约 600 至 800 英尺的低速至中速驱动;然而,在每分钟约 2,000 至 3,000 英尺的较高速度下,由于磨损和噪音问题,通常使用 V 型皮带。
自行车链条是一种滚子链。自行车链条可能带有主链节,也可能需要使用专用工具进行拆卸和安装。大多数摩托车使用类似但尺寸更大、强度更高的链条,不过有时也会用齿形皮带或轴传动代替,因为后两者噪音更低,维护需求也更少。
绝大多数汽车发动机都使用滚子链来驱动凸轮轴。高性能发动机通常使用齿轮传动,而从20世纪60年代初开始,一些制造商开始使用齿形带。
链条也用于以液压缸为滑轮的叉车中,以升降货叉;然而,这些链条不属于滚子链,而是被归类为提升链或板式链。
链锯切割链条表面上与滚子链相似,但实际上与板式链更为接近。它们由突出的驱动链节驱动,这些链节也起到将链条固定在导板上的作用。
海鹞FA.2 ZA195 CZPT(冷态)矢量推力喷管——该喷管由气动马达通过链条驱动旋转
摩托车链条的一个不寻常的用途是在鹞式跳跃 CZPT 中,它利用气动马达的链条驱动来旋转可移动的发动机喷嘴,使其向下指向以进行悬停飞行,或向后指向以进行正常的向前飞行,该系统被称为推力矢量控制。
自行车链条磨损
自行车变速器的轻型链条容易断裂(或者更准确地说,是侧板断裂,因为铆接通常会先失效),这是因为链条内部的销钉并非圆柱形,而是桶形。销钉与衬套的接触点并非直线,而是点状,这使得链条的销钉能够穿过衬套,最终穿过滚子,导致链条断裂。这种结构是必要的,因为这种传动方式的变速动作需要链条进行侧向弯曲和扭转,而自行车上这种细链条的柔韧性以及相对较长的自由长度,使得这种现象容易发生。
在轮毂变速系统中(例如 CZPT dix 两速变速器、Sturmey-Archer AW),链条故障的问题要少得多,因为平行销与衬套的接触面积更大。轮毂变速系统还能实现完全封闭,这极大地有利于润滑和防止沙砾进入。
链强度
滚子链强度的最常用指标是抗拉强度。抗拉强度是指链条在断裂前能够承受的单次载荷。与抗拉强度同样重要的是链条的疲劳强度。影响链条疲劳强度的关键因素包括:链条制造所用钢材的质量、链条部件的热处理工艺、链节板节距孔的加工质量以及链节板上喷丸的类型和喷丸覆盖强度。CZPT 因素还包括链节板的厚度和设计(轮廓)。对于连续驱动的滚子链,经验法则是:链条载荷不应超过其抗拉强度的 1/6 或 1/9,具体取决于所使用的主链节类型(压入配合或滑动配合)。[需要引用]滚子链在连续驱动下运行超过这些阈值时,通常会因链板疲劳失效而过早失效。
ANSI 29.1 钢链的标准最小极限强度为 12,500 x(节距,以英寸为单位)2X型环和O型环链条通过内部润滑剂大大降低磨损,从而延长链条寿命。内部润滑剂是在铆接链条时利用真空注入的。

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 |
通常情况下,链节形状平行的链条链节数为偶数,每个窄链节后紧接着一个宽链节。而由一端窄另一端宽的同类型链节构成的链条,链节数可以是奇数,这有利于适应特殊的链轮间距;但另一方面,这种链条的强度往往较低。
采用 ISO 标准制造的滚子链有时被称为等轴链。
