Jis B 1702-1 Pdf

The standard, officially titled "Cylindrical gears — ISO system of flank tolerance classification — Part 1: Definitions and allowable values of deviations relevant to flanks of gear teeth", is a critical document in the world of mechanical engineering. Published by the Japanese Standards Association (JSA) , it defines a comprehensive tolerance classification system for the tooth flanks of individual cylindrical involute gears.

This measures the deviation of the actual tooth profile from the designed involute curve.

) : The maximum error over the entire circumference of the gear, critical for indexing accuracy. How to Read JIS B 1702-1 Tolerance Tables

It defines 13 distinct grades of gear accuracy, classified from 0 (highest) to 12 (lowest) . jis b 1702-1 pdf

Understanding JIS B 1702-1: The Standard for Cylindrical Gear Accuracy

Precise definitions of gear deviations (e.g., pitch deviations, profile deviations, lead deviations).

JIS B 1702-1, titled "Cylindrical gears — ISO system of accuracy — Part 1: Definitions and allowable values of deviations relevant to corresponding flanks of gear teeth," is a Japanese Industrial Standard that provides a standardized system for classifying gear accuracy. The standard, officially titled "Cylindrical gears — ISO

One of the most important facts about this standard is its international compatibility.

The spacing accuracy between adjacent teeth and the cumulative spacing over the entire gear.

(Profile Deviation): How the actual tooth shape deviates from the perfect involute curve. fβf sub beta ) : The maximum error over the entire

The old system used grades ranging from Class 0 (highest precision) to Class 9 (lowest precision). The Modern Standard (JIS B 1702-1:1998 / ISO Equivalent)
