Jis - B 1702-1 Pdf

Because it aligns with ISO 1328-1, it ensures that Japanese-manufactured products are compatible with international requirements. How to Obtain 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.

The PDF, such as the JIS B 1702-1:2016 version , defines several critical deviations that manufacturers must monitor: 1. Pitch Deviations jis b 1702-1 pdf

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

When you finally open that PDF, you will notice something shocking: It looks almost exactly like ISO 1328-1. Because it aligns with ISO 1328-1, it ensures

JIS B 1702-1 standard, titled "Cylindrical gears — ISO system of flank tolerance classification — Part 1: Definitions and allowable values of deviations relevant to corresponding flanks of gear teeth,"

It defines 13 distinct grades of gear accuracy, classified from 0 (highest) to 12 (lowest) . The PDF, such as the JIS B 1702-1:2016

. It replaced the older 1976 version of the JIS gear accuracy standards to provide a more rigorous, mathematically defined classification system. Key Specifications & Classification Accuracy Grades : The standard defines 11 quality grades , ranging from (highest precision, typically for master gears) to

The JIS B 1702 series is divided into multiple parts to address different measurement methods and materials: Accuracy of Gears | KHK

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

Understanding and implementing this technical document is crucial for engineers, quality inspectors, and gear manufacturers looking to guarantee smooth mechanical power transmission, minimize noise, and prevent premature component failure.
