标准摘要
[中文适用范围]： 本文件规定了G、H、R和S型轮廓系统的节距齿数皮带和轮齿的主要特性，适用于机械功率传递和需要正向 indexing 或同步的场合。 [外文原描述]： This document specifies the principal characteristics of metric pitch curvilinear synchronous endless belts and pulleys in G, H, R, and S profile systems for use in synchronous belt drives (also known in the past as timing belt drives, positive belt drives, gear belt drives) for mechanical power transmission and where positive indexing or synchronization can be required. The principal belt and pulley characteristics include the following: a) nominal belt tooth dimensions; b) belt tooth pitch spacing; c) belt length and width dimensions and tolerances; d) belt length measurement specifications; e) pulley groove dimensions and tolerances; f) pulley diameter and width dimensions and tolerances; g) pulley quality specification.
