The specific allowable values for each deviation are defined by complex formulae within the standard, which vary based on the gear's size, modulus, and accuracy grade.

Inside the standard's tables, formulas use these variables to calculate the maximum allowable error in micrometers ( The specific allowable values for each deviation are

When you open a JIS B 1702-1 PDF, the document is heavily anchored by formulas, tolerance tables, and specific geometric deviations. Understanding these parameters is vital for reading the standard effectively: Single Pitch Deviation ( fptf sub p t

Extremely high precision (gears for high-speed, precision instruments, or specialized machinery). Understanding these parameters is vital for reading the

For spur and helical gears, the standard establishes a series of accuracy grades, from (highest accuracy) to N12 (lowest accuracy). The 'N' prefix (e.g., N7, N8, N9) explicitly denotes that the gear is classified under the 1998 or newer revision of the standard. This helps to prevent confusion with the older grades from the superseded JIS B 1702:1976 standard.
