TS 2377

TS 2377 is a terminology-oriented standard for chains used in force and power transmission, focusing on how the relevant terms are defined and how these chains are classified. Its emphasis is not on detailed design rules, but on a shared technical language and grouping basis that help users describe chain-driven transmission systems consistently.

How terminology supports chain transmission practice

In mechanical power transmission, chains are used to transfer rotation from one shaft to another, maintain a speed ratio, or convey loads. In practice, terminology helps distinguish concepts such as pitch, chain type, intended use, and the way the components are assembled. The definitions and classification basics covered by this standard are meant to reduce ambiguity and support clear technical communication across different chain applications.

Technical scope reflected by the standard

• It organizes the basic terms used for chains in force and power transmission.
• It establishes the basic principles used to classify those chains.
• Its main purpose is to harmonize terminology and technical distinction; it should be read as a definitions and classification standard rather than a performance standard.
• From its title and scope, it addresses the core vocabulary and grouping logic for chain-driven transmission systems.

Standards of this kind are especially useful because they let designers, manufacturers, suppliers, and maintenance teams refer to the same component in the same way. That improves clarity when selecting chains, reading catalogs, drafting specifications, or maintaining technical documentation. TS 2377 therefore serves as a common reference for describing chains used in force and power transmission in a precise and consistent manner.
