To properly utilize a JIS B 1702-1 PDF or reference manual, you must understand the primary elemental deviations it regulates. Quality control departments use specialized Gear Measuring Machines (GMMs) to extract these specific metrics. 1. Pitch Deviations (Fp, fpt) Single Pitch Deviation ( fptf sub p t end-sub

The standard focuses on four primary types of gear deviations:

JIS B 1702-1 specifically defines the . It applies to both external and internal gears with straight, helical, or herringbone teeth. jis b 1702-1 pdf

: Authorized copies should be obtained directly from the Japanese Standards Association (JSA) or official international distributors like ISO or IHS Markit.

: Represents the lowest precision tier (coarse commercial gears). To properly utilize a JIS B 1702-1 PDF

JIS B 1702-1 is the first part of the Japanese Industrial Standard that specifies the accuracy classification system and definitions for the tangential and radial deviations of spur and helical cylindrical gears.

errors lead to instantaneous velocity changes and heavy noise. Total Cumulative Pitch Deviation ( Fpcap F sub p Pitch Deviations (Fp, fpt) Single Pitch Deviation (

Often referred to in older designs, covering 13 grades of accuracy (0–12). "N" Grade:

: It specifies the maximum permissible deviation values (tolerances) for different accuracy classes. Common classes found in industrial catalogs include Class 5 (high precision ground gears) and Class 9 (general use).

Errors in the axial direction (lead error), which can cause poor tooth contact and noise. 3. Key Updates (Old vs. New Standards)
