ISO 19347:2015 specifies the principal characteristics of synchronous endless belts and pulleys for use in synchronous endless belt drives[1] for mechanical power transmission and where positive indexing or synchronization is required. The principal characteristics includes the following: a) belt nominal tooth dimensions; b) belt length and width dimensions and tolerances; c) belt length-measurement specifications; d) pulley grooves dimensions and tolerances; e) pulley dimensions and tolerances; f) pulley quality specification. [1] These drives have been known under various names in the past, for example: timing belt drives, positive belt drives, gear belt drives.
