Belt drives — Grooved pulleys for joined narrow V-belts — Groove sections 9N/J, 15N/J and 25N/J (effective system)

Transmissions par courroies — Poulies à gorges pour courroies trapézoïdales étroites — Sections de gorge 9N/J, 15N/J et 25N/J (système effectif)

Abstract / scope

This International Standard specifies the principal characteristics of grooved pulleys (for groove sections 9N/J,

15N/J and 25N/J) intended to take both single and joined narrow V-belts for industrial power transmission drives.

Some background information on the series of effective diameters is given in annex A.

NOTE The effective width of a groove is regarded as the basic dimension of standardization in the effective system for

grooves and for the corresponding narrow V-belts considered as a whole.
