滚子链基础知识
在为您的机器选择合适的滚子链之前，有必要了解一些基础知识。例如链轮、抗拉强度、节距和宽度。阅读本文了解更多信息，这将有助于您做出明智的选择。选择合适的产品至关重要，但这并非总是像选择一个品牌那么简单。您需要选择一家能够为其产品提供支持并提供良好售后服务的公司。
滚子链轮
如果您计划为您的应用采购滚子链轮，首先应该了解各种可用的类型。波士顿钢铁公司生产的B型链轮适用于单股滚子链，并已预先钻孔至所需尺寸。它们的节距尺寸有1/4英寸、3/8英寸、1/2英寸、5/8英寸、3/4英寸和1英寸可供选择。
选择合适的链轮时，链轮的直径至关重要。使用卡尺测量无齿盘的直径是确定链轮精确尺寸的好方法。卡尺测量的是无齿盘的直径。对于B型和C型链轮，轮毂直径指的是轮毂的厚度。
Another type of sprocket is the steel split sprocket, which is split in diameter. This type is easy to install and remove, and is held together by bolts in the hub. Typically, split sprockets have chain pitches ranging from 40 to 240 and bores ranging from 3/4″ to 6″. The split sprockets are designed with 1 pointing towards the ceiling and the other 2 parallel to the floor.
选购链轮时，务必记住它们是专为特定链条设计的。所有链条都按照特定标准制造。在美国，最常用的标准是ANSI标准。链条节距是指相邻两个链销中心之间的距离。在美国，该标准始终以8英寸为单位进行测量。
除了链轮尺寸外，链轮节距和表面积也会影响链条寿命。与锻钢制成的皮带链轮不同，滚子链轮的齿是由钢板冲压而成或由粉末冶金压制而成。齿越硬，链条的使用寿命就越长。
滚子链节距
滚子链的节距是指链轮与销轴之间的距离。螺纹节距越小，衬套磨损越小。一般来说，节距越小，链条寿命越长。为了获得最佳性能和最长使用寿命，制造商建议最小链条节距为 2% 至 3%。链条节距对于确保正常性能至关重要，制造商建议当链条节距达到 2% 至 3% 时更换链条。
要确定特定链条的正确节距，首先要确定链轮的尺寸和节距。节距是指两个销轴中心之间的距离，以 1/8 英寸为增量进行测量。链条的销轴直径也很重要。如果您不确定链条的销轴直径，可以测量几个链节以获得一个大致的平均值。或者，您也可以使用游标卡尺测量链轮的内径并数出齿数。
选择链轮尺寸时，用游标卡尺测量齿轮间的链条长度，并与链条尺寸表上的尺寸进行比较。务必检查所有规格并确认链条节距正确。然后，根据您的需求选择合适的链条节距。这是选择合适链条的关键步骤。因此，请务必为您的滚子链选择正确的节距。正确的节距有助于确保最佳性能和安全性。
要识别特定类型的滚子链，需要测量其抗拉强度。抗拉强度代表链条断裂前所能承受的载荷。另一个需要考虑的关键参数是疲劳强度。疲劳强度高的链条比疲劳强度低的链条更耐锈蚀和磨损。标准编号中右侧的数字代表普通或轻型链条，而左侧的数字代表重型链条的节距。
Double pitch roller chains are a variant of single pitch chains. They are manufactured according to ISO 606 and meet the same standards as single pitch chains. They are mainly used in applications with lower requirements for speed and power transmission. The plates of double pitch roller chains are also longer than single pitch chains. The double pitch drive series is also used for elevator and long conveyor drives. There are 3 main types of roller chains: single-pitch chains, double-pitch carriers, and oversized rollers.
滚子链宽度
When buying a roller chain, 1 of the first decisions you must make is its width. To make this determination, you need to measure the overall width of the chain, the diameter, and the width of each roller. You must also know the height and thickness of the board. After taking these measurements, you can start shopping for the perfect roller chain. But before you buy a new chain, it’s important to know what to expect from the chain itself.
滚子链种类繁多，有多种规格，包括美制和公制尺寸。它们有单股和双股两种类型，通常用于动力传输。其他类型包括农业用链、汽车用链、输送链、多股链和四股链。这些图表还包含一个尺寸对照表，方便您轻松找到所需的确切尺寸。以下列出了购买滚子链的一些优势。
Roller diameter and pin diameter are important factors in choosing the correct chain width. The width of the chain is the nearest binary fraction of 5/8 of an inch. It should be at least half the thickness of the sprocket, and the plate thickness is one-8h the width of the chain. Overweight chains are indicated with the suffix H. The pitch and width of the chain are determined by the working load and machine speed.
滚子链的外侧链节称为销轴链节。这些销轴插入相邻滚子链节的衬套中，并由开口销固定。重型链条通常将销轴链节压入销轴中。这些销轴用于固定滚子。然而，这些销轴链会使滚子链的额定功率降低高达 20%。
ANSI 29.1钢链规范规定了最小节距（以英寸为单位）和极限强度为12,500×节距（以英寸为单位）。同时，O型环链由于其润滑作用，能显著降低磨损。O型环链和X型环链在铆接过程中通过真空注入润滑剂。传动链的测试和规范由ANSI等标准机构制定。2011年，美国机械工程师协会（ASME）制定了精密动力传动链的标准。
滚子链抗拉强度
滚子链强度最重要的指标之一是抗拉强度。该指标指的是链条在断裂前所能承受的最大载荷。另一个指标是疲劳强度，指的是链条在断裂前所能承受的最大载荷。滚子链的强度取决于其尺寸、制造所用钢材的质量以及热处理工艺。此外，钢材的喷丸处理方式、节圆孔和链节板也会影响其强度。
选择滚子链时，负载能力至关重要。负载能力是指链条在发生疲劳失效前所能承受的最大载荷。这项指标非常重要，因为它有助于确定链条所承受的载荷类型。在决定购买哪种滚子链时，务必考虑其机械类型和所需的强度。然后，确保其满足强度和承载能力的要求。
滚子链的极限抗拉强度基于制造商推荐的最大抗拉强度。然而，实际抗拉强度可能高于或低于该值。滚子链的工作载荷极限也可以通过将链条直径乘以链条等级来计算。链条的工作载荷极限是指其在断裂前所能承受的最大拉力。该值通常以磅数表示。
The maximum tensile strength of roller chains varies by chain type. The single-strand heavy chain has thick side plates for higher shock loads. Single strand heavy-duty roller chains, also known as “bushing” roller chains, are also available. Double-stranded heavy chains are structurally similar, but they have 2 layers of steel connected by pins that are nearly twice as strong as standard roller chains.
The tensile strength of a single-strand roller chain is approximately 500 tons. In comparison, a single-chain blockchain has a tensile strength of 900. The tensile strength of the 2 is similar, and it is not recommended to choose 1 or the other. Although steel and titanium chains are considered the strongest materials for roller chains, these materials are not magnetic.
