JIS B 1702-1 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,"
The JIS B 1702-1 is a Japanese Industrial Standard that defines the accuracy and tolerance classification for cylindrical gears (spur and helical gears). It was last revised in 2016 and is technically aligned with the international standard ISO 1328-1. 🔩 Core Purpose
Step 1: Define the Gear Data You need: Module (m), Number of teeth (z), Reference diameter (d), Face width (b). jis b 1702-1 pdf
Found in the PDF's section on "Pitch deviations." If your gear has high Fp, it will vibrate. The JIS table provides exact micrometers (µm) of error allowed based on pitch diameter and grade.
JIS B 1702-1 is a Japanese Industrial Standard specifying terminology, classifications, and requirements for protective gloves for industrial use — part 1 covers general definitions and basic requirements that apply across glove types used in industry. JIS B 1702-1 standard, officially titled "Cylindrical gears
Pitch Deviations: Errors in the spacing between teeth, affecting the smoothness of rotation.
Tolerance Classification System: It establishes a system for classifying the accuracy of gear tooth flanks, moving away from older numerical grading systems (like the previous JIS B 1702:1976) toward the ISO-aligned system. JIS B 1702-1 vs
The Jis B 1702-1 pdf provides a standardized framework for evaluating the accuracy of gear teeth, ensuring that they meet the required specifications for smooth and efficient operation. By adhering to this standard, manufacturers can:
