Communiqué on TS ISO 5291 Belt Drive - Grooved Pulleys for Classical Combined V Belts - Groove Profile AJ, BJ, CJ and DJ (Effective System) for the Assemblies Standard (2 page(s), in English)
This standard covers the main characteristics of grooved pulleys (groove profile AJ, BJ, CJ and DJ) designed for combined classical V-belts intended for industrial power transmission drive systems.
The effective width of a groove is considered as the main dimension of standardization for grooves that are evaluated as a whole and corresponding combined V belts.
The pitch line position can only be approximated. The approximate pitch diameter of a pulley can be calculated by the following equation. DP = DE - 2BE
