Описание (английский):

ISO 9980:2012 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 can be designed for use with classical or narrow V-belts. The V-belts can be either single or joined units.

Overview

ISO 9980:2012 - "Belt drives - Grooved pulleys for V‑belts (system based on effective width) - Geometrical inspection of grooves" - defines standardized methods for geometrical inspection of pulley grooves used with classical or narrow V‑belts (single or joined). The standard sets out a four‑step inspection sequence to verify groove regularity and conformity with effective‑width based dimensions, helping manufacturers and quality teams ensure reliable belt drive performance.

Key topics and requirements

Inspection principle: Complete inspection is carried out in four successive checks -

groove profile, 2) groove spacing, 3) effective diameter, 4) run‑out tolerances.

Groove profile: Specifications include effective width, groove angle, groove depth, sidewall bevel depth and (for joined belts) groove land height. Limit gauges are used to check minimum/maximum angle, effective width and depth; different gauge ends and angles are required per groove section.

Groove spacing: For multiple‑groove pulleys the nominal spacing (e) and tolerances are specified. Inspection uses a groove spacing locator and sets of interchangeable inspection balls; measured dimension minus ball diameter gives groove spacing.

Effective diameter: Nominal effective diameter and allowable variation or tolerances between grooves are specified. Measurement uses two cylindrical balls or rods; the measured separation between tangent planes minus a corrective term (2hs) yields the effective diameter.

Run‑out tolerances: Radial and axial circular run‑out tolerances for specified measurement positions are defined; inspections are performed during one revolution about the bore axis. Datum references and measurement distances are specified.

Inspection tools and markers: Limit gauges, balls/rods, Vernier calipers and groove locators are described for repeatable production control.

Practical applications

Ensures dimensional conformity of grooved pulleys used in industrial transmissions and automotive belt drives.

Supports production control, incoming‑inspection, tooling set‑up and acceptance testing.

Reduces belt wear, vibration and misalignment by verifying groove geometry, spacing and run‑out.

Useful for manufacturers producing grooved pulleys, test laboratories, maintenance teams and purchasing/specification engineers.
