Belt drives - Grooved pulleys for V-belts (system based on effective width) - Geometrical inspection of grooves
This International Standard specifies the methods of checking the regularity of the grooves and pulleys for V-belts specified in the system based on effective width. The grooved pulleys may be designed for use with classical or narrow V-belts. The V-belts may be either single or joined units.
The inspection parameters and tolerances of grooved pulleys will be specified in future International Standards.
