Full title and description

Code of inspection practice — Part 3: Recommendations relative to gear blanks, shaft centre distance and parallelism of axes. This technical report gives recommended numerical values and guidance for dimensional deviations of gear blanks, permissible centre distance deviations and acceptable parallelism of gear axes; the values are intended as guidance for agreements between purchaser and supplier rather than mandatory quality grades.

Abstract

ISO/TR 10064-3:1996 provides recommended values and explanatory guidance for inspection-related dimensions of gears: gear blank form and tolerances, shaft centre distance deviations and parallelism of axes. The numerical values are presented as recommendations to assist mutual agreements and inspection practice rather than as prescriptive ISO quality classes. A technical corrigendum was published in 2006 to correct or clarify select items.

Scope

This technical report gives recommendations for inspection practice relating to gear blanks, the allowable deviations of shaft centre distance and the required parallelism of gear axes. It is intended to support manufacturers, purchasers and inspection bodies by providing recommended numerical values and explanatory text to be used as the basis for contractual or inspection agreements. The recommendations are advisory and are not presented as mandatory ISO quality classifications.

Key topics and requirements

• Recommended dimensional deviation values for gear blanks (form and size) to be used as guidance in inspection agreements.
• Guidance and numerical limits for permissible deviations in shaft centre distance between mating gears.
• Recommendations on acceptable parallelism tolerances for gear axes and how these tolerances affect gear meshing and performance.
• Explanatory notes clarifying that numerical values are for guidance and that contractual agreements should specify acceptance criteria; corrections and clarifications published in a 2006 corrigendum.

Typical use and users

Used by gear manufacturers, quality and metrology engineers, inspection laboratories, purchasers specifying acceptance criteria, and design engineers concerned with assembly and performance of gear pairs. The report supports inspection planning, acceptance criteria negotiation and supplier–buyer technical agreements.

Related standards

Q: What does it cover?

A: It covers recommended numerical values and explanatory guidance for gear blank dimensions, permissible shaft centre distance deviations and parallelism tolerances for gear axes; the recommendations are advisory and intended for use in mutual agreements between manufacturers and purchasers.

Q: Who typically uses it?

A: Gear manufacturers, design and quality engineers, inspection and metrology laboratories, procurement/specification engineers, and standards committees use this report to define inspection practice and acceptance criteria.

Q: Is it current or superseded?

A: The report was published in August 1996 and a Technical Corrigendum (ISO/TR 10064-3:1996/Cor 1:2006) was issued to correct or clarify parts of the document; users should consult ISO or national standards bodies for the definitive current status before relying on it for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — ISO/TR 10064 is a multi-part code of inspection practice series covering different aspects of gear inspection and measurement (e.g., parts 1, 2, 5, 6 and others address flank measurement, composite deviations, instrument evaluation and bevel gear methods). ISO/TR 10064-3 is Part 3 of that series.
