This is usually “40” or “C2080H”, but can also be the letter “B”. If the chain is old, it will need to be cleaned to see its size. You can find the size on the standard roller chain size chart, but not everyone is marked. To determine the size, measure the diameter and pitch of the chain, then compare the results to the chart to see what size you need. 无衬套链条Bushless roller chains have advantages over conventional roller chains. Unlike conventional chains, bushless chains have extensive lateral flexibility, which increases the chain’s lubrication flow. The inner plates of bushless chains have protruding shoulders so the oil can flow through them more easily and efficiently. This is an important characteristic of a smooth-running chain. Additionally, bushless chains may have improved shifting performance. 静音链静音滚子链具有平稳、低噪音的传动特性。它由堆叠的扁平链板组成,链板呈齿轮状,与链轮齿啮合。每个链板都连接到相应的链轮上,这也使得链条能够弯曲。虽然所有静音滚子链的基本组成部分都相同,但其众多变体使其能够应用于各种不同的领域。 ANSI 链节To measure your bike’s chain pitch, you can use a caliper. This measurement is taken from the center of the rolling pin to the center of the next rolling pin. Chains come in many sizes, but ANSI is the most common chain standard in the United States. A caliper is handy if you’re not sure which size to buy, as it allows you to check for worn sprockets. 滚子链磨损测量滚子链磨损测量的目的是通过监测链条的应力来防止断裂。测量滚子链磨损的方法有多种。第一种方法是将链条从工作位置拆下,测量链轮到测量端的距离。另一种方法是测量链条的节距,即两个销之间的距离。这种方法优于其他方法,因为它更便捷、更准确。
