The updated standard inverted and expanded the scale. It introduces , where:

This part of the JIS B 1702 series specifically addresses deviations relevant to the flanks of gear teeth. It defines critical parameters for measuring accuracy, including:

While technical summaries provide an overview, the actual is required for manufacturing and compliance. The standard contains complex look-up tables for tolerance values based on the module, reference diameter, and tooth width. jis b 1702-1 pdf

For any engineer manufacturing or procuring gears in Japan or adhering to Japanese Industrial Standards, understanding JIS B 1702-1 is non-negotiable. It is the primary reference for defining and inspecting the quality of spur and helical gears.

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 . The updated standard inverted and expanded the scale

The document defines several types of tooth deviations that impact gear performance:

When checking an engineering drawing or a CNC gear metrology chart, JIS B 1702-1 centers on three core elemental measurement categories: Pitch Deviations Single Pitch Deviation ( fptf sub p t end-sub The standard contains complex look-up tables for tolerance

JIS B 1702-1 is an important standard for gear manufacturers, as it provides a set of guidelines for designing and manufacturing high-quality gears. By following the standard, manufacturers can ensure that their gears meet the required performance and safety standards.

It provides the numerical data needed to verify that manufactured gears meet design specifications.
