Overview
SIST ISO 255:1995 specifies standardized methods for the geometrical inspection of grooves in pulleys for V-belt drives, based on the datum width system. Prepared by SIST in alignment with ISO procedures, this standard facilitates quality assurance and consistency in grooved pulley manufacturing. The requirements are applicable to both classical and narrow V-belt pulley systems.
Regular inspection of V-belt pulley grooves is essential for reliable power transmission and minimal belt wear. This standard outlines inspection techniques and dimensional checks to ensure compliance with international specifications.
Key Topics
Applications
SIST ISO 255:1995 is highly relevant to industries and organizations involved in:
- Manufacturing and Quality Control: Used during production and incoming inspection of V-belt pulleys to verify dimensional compliance and minimize belt failures.
- Mechanical Engineering: Ensures interoperability and interchangeability of standard V-belt components in machinery, vehicles, and industrial drives.
- Maintenance and Safety: Facilitates preventive maintenance checks in power transmission systems, reducing downtime and extending equipment life.
- Supplier Audits and Certification: Provides a unified basis for auditing, tendering, and certifying grooved pulley products to international standards.
The standard helps maintain consistency across different manufacturers and sectors using V-belt drive systems, supporting robust mechanical performance and global trade in standardized components.
Related Standards
To maximize the benefit and ensure compatibility, consider these related international standards:
- ISO 4183: Defines groove profiles and dimensions for classical and narrow V-belt grooved pulleys (datum width system).
- ISO 286-2: Reference for standard tolerance grades and permissible deviations for holes and shafts.
- ISO 1081: Establishes terminology for drives using V-belts and grooved pulleys.
- ISO 1101: Provides general principles and symbols for geometrical tolerancing, including forms, orientation, location, and run-out.
Using SIST ISO 255:1995 in conjunction with these standards supports comprehensive geometrical and dimensional control in V-belt transmission component production.
