Jis B 1702-1 Pdf -

JIS B 1702-1 is an essential, legally protected standard for cylindrical gear accuracy. While many search for a “free PDF,” the safest, most reliable, and legal access comes from the JSA Web Store (paid PDF) or KIKAKU (free web reading). Always verify the revision year (2015+ recommended) and remember that Part 1 focuses only on tooth flank deviations. For complete gear quality documentation, pair it with JIS B 1702-2.

Final recommendation: Do not risk downloading from unverified PDF hosting sites. Pay the ~$35–40 USD for the official PDF from JSA – it is tax-deductible, up-to-date, and legally clean for use in audits and production.

The JIS B 1702-1 standard is a critical Japanese Industrial Standard that defines the accuracy and tolerance classification for cylindrical involute gears. Established to align Japanese manufacturing with international benchmarks, it is essentially the Japanese equivalent of the ISO 1328-1 standard.

If you are looking for the official document, you can find the current 2016 version through the Japanese Standards Association (JSA) Webdesk. What is JIS B 1702-1?

JIS B 1702-1 specifically focuses on flank tolerance classification. It provides the definitions and allowable values for deviations on the flanks of gear teeth, ensuring that gears from different manufacturers can function reliably together in a system. jis b 1702-1 pdf

Scope: Applies to individual spur and helical gears (not gear pairs).

Accuracy Grades: The standard utilizes a system of 13 grades, numbered from 0 to 12.

Grade 0: The highest precision, typically used for aerospace or high-end metrology.

Grade 12: The lowest precision, often sufficient for simple agricultural or manual machinery. JIS B 1702-1 is an essential, legally protected

The "N" Prefix: To distinguish from the older JIS B 1702:1976 standard, these newer grades are often prefixed with an "N" (e.g., N5). Key Accuracy Parameters

The standard measures several specific types of errors to determine a gear's grade: Jis B 1702-1 | PDF - Scribd
