链条的构造

两种不同尺寸的滚子链,展示其结构。
衬套式滚子链有两种交替排列的链节。第一种是内链节,由两块内链片组成,通过两个套筒或衬套固定,两个滚子在其上旋转。内链节与CZPT型外链节交替排列,外链节由两块外链片组成,通过穿过内链节衬套的销钉固定。“无衬套”滚子链的工作原理类似,但结构不同;它不是用单独的衬套或套筒固定内链片,而是在链片上冲压一个从孔中伸出的管子,起到相同的作用。这样做的好处是简化了链条的组装步骤。

变体设计

滚子链的组成结构:1. 外链板,2. 内链板,3. 销,4. 衬套,5. 滚子
如果链条并非用于高磨损应用(例如,仅用于将手动操纵杆的运动传递到机器的控制轴,或驱动烤箱的滑动门),则仍可使用较为简单的链条类型。相反,如果需要更高的强度和更小节距带来的平稳传动,则可使用“连体”链条;链条外侧不再只有两排链板,而是三排(“双联”)、四排(“三联”)或更多排链板平行排列,每两排链板之间用衬套和滚子连接,链轮上也对应着相同数量的平行齿排。例如,汽车发动机上的正时链条通常由多排链板组成,称为链节。

使用

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,这些链条不被认为是滚子链,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。

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump CZPT , 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 forward flight, a system known as Thrust

穿

滚子链磨损的影响是增加节距(链节之间的间距),导致链条伸长。请注意,这是由于枢轴销和衬套的磨损造成的,而不是金属本身的拉伸(某些柔性钢部件,例如汽车的手刹拉索,确实会发生这种情况)。

现代链条(自行车链条除外)很少会磨损到断裂,因为磨损的链条会导致链轮齿快速磨损,最终导致链轮所有齿全部脱落。链轮(尤其是较小的那个)会受到摩擦运动,在齿的驱动面上形成一个特征性的钩状磨损。(链条张紧不当会加剧这种磨损,但无论采取何种保养措施都无法避免)。磨损的齿(和链条)无法提供平稳的动力传输,这可能从噪音、振动或(在使用正时链条的汽车发动机中)使用正时灯观察到的点火正时变化中看出。在这种情况下,链轮和链条都应该更换,因为在磨损的链轮上使用新链条也无法持久。然而,在磨损程度较轻的情况下,或许可以保留较大的那个链轮,因为磨损最严重的通常是较小的那个。只有在自行车等非常轻型的应用中,或者在张力极不合适的极端情况下,链条才会从链轮上脱落。

在工业领域,通常会监测链条张紧器(无论是手动还是自动)的运行情况,或者测量驱动链条的精确长度(一个经验法则是,如果可调式驱动装置的滚子链伸长了 3%,或者固定中心驱动装置的滚子链伸长了 1.5%,就需要更换)。一个更简单的方法,尤其适用于自行车或摩托车用户,是在确保链条张紧的情况下,尝试将链条从两个链轮中较大的那个链轮上拉开。任何明显的移动(例如,可以透过缝隙看到另一侧)都可能表明链条磨损已达到或超过极限。如果忽视这个问题,会导致 CZPT 损坏。CZPT 的磨损会抵消这种影响,并且可能会掩盖链条的磨损。

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. CZPT 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.

链上杭州路

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 CZPT Transmission Roller Chains, Attachments, and CZPT s) developed by the CZPT ican Society of CZPT Engineers (ASME). See the references for additonal information.
