Synchronous belt drives - Imperial pitch trapezoidal profile system - Belts and pulleys

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
