Belt drives - Classical and narrow V-belts - Grooved pulleys (system based on datum width)

Cancels and replaces the second edition (1989). Specifies the principal dimensions of grooved pulleys for classical V-belts and narrow V-belts specified in the terminology system based on datum width. It is important that narrow belts are not used with pulleys uniquely designed for classical belts, and, on the other hand, that multiple belt drives are not used with joined V-belts.

Overview

ISO 4183:1995 is an international standard published by the International Organization for Standardization (ISO) that specifies the principal dimensions for grooved pulleys used with classical and narrow V-belts. This standard, a revision and replacement of the earlier 1989 edition, defines the system based on the datum width, ensuring compatibility and interchangeability across pulleys and belt drives.

The standard emphasizes the importance of using narrow V-belts exclusively with pulleys designed for them and prevents the use of multiple belt drives with joined V-belts. It covers groove profiles, groove angles, datum widths and diameters, quality, surface finish, balancing, and inspection methods for pulleys.

Key Topics

• Datum Width System: ISO 4183:1995 adopts the datum width as the fundamental dimension for standardizing groove and belt profiles. Understanding the datum line position and datum width is critical for defining groove profiles and belt-pulley compatibility.

• Grooved Pulley Dimensions: The standard specifies exact dimensions for groove profiles for both classical (sections Y, Z, A, B, C, D, E) and narrow V-belts (sections SPZ, SPA, SPB, SPC). Groove angles are standardized at 32°, 34°, 36°, or 38°, with a tolerance of ±0.5°.

• Datum Diameters: Pulleys come in nominal datum diameters selected from ISO's preferred number series (R 40 series), with recommendations differentiated for classical and narrow V-belts. The standard establishes minimum diameters and maximum permissible differences between grooves on the same pulley, crucial for multiple belt drives.

• Quality and Inspection: ISO 4183 refers to additional standards for pulley quality, surface finish, and balancing (ISO 254), as well as geometric inspection of grooves (ISO 255), ensuring reliability and performance in belt drives.

• Compatibility Warnings: The standard underlines that narrow belts should not be used with pulleys made solely for classical belts and discourages using multiple belt drives with joined V-belts, a key consideration for system designers and engineers to prevent premature wear or failure.

Applications

• Industrial Power Transmission: ISO 4183:1995 is vital for mechanical engineers designing power transmission systems in manufacturing plants, agriculture machinery, and conveyor systems relying on V-belt drives.

• Maintenance and Replacement: Facilities maintenance teams use the standard to select appropriate replacement pulleys and belt types, ensuring compatibility to maintain system efficiency and prolong equipment life.

• Quality Control in Manufacturing: Pulley manufacturers apply the dimensional and inspection requirements from the standard to ensure products meet international quality expectations, enabling global trade and interoperability.

• Design of Customized Machinery: Machine designers utilize the standard's detailed groove and diameter specifications when integrating classical or narrow V-belt drives to achieve optimal load transmission and reduce slippage.

Related Standards

• ISO 254:1990 - Belt Drives: Pulleys - Quality, finish, and balance
• ISO 255:1990 - Belt Drives: Pulleys for V-belts - Geometrical inspection of grooves
• ISO 1081:1980 - Drives using V-belts and grooved pulleys - Terminology
• ISO 1101:1983 - Technical drawings - Geometrical tolerancing - Form, orientation, location, and run-out

These complement ISO 4183 by addressing quality parameters, inspection methods, and terminology, providing a comprehensive framework for V-belt drive design and manufacturing.

étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernemen-
tales, en liaison avec I’ISO participent également aux travaux. L’ISO colla-
bore étroitement avec la Commission électrotechnique internationale (CEI)
en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l’approbation de 75 % au moins des co-
mités membres votants.
