The difference between the actual and theoretical tooth profile. Helix Deviation ( cap F sub beta

: Grades 6 through 9 are common for general industrial machinery.

The core function of the standard is to establish a formal for the tooth flanks (the functional surfaces) of individual cylindrical involute gears. Think of it as a rulebook that defines exactly how to measure gear errors and what levels of error are acceptable for different classes of precision. This classification is critical for determining the appropriate manufacturing processes, from high-precision grinding to economical hobbing.

While AGMA (American Gear Manufacturers Association) uses a different numbering system (Q-grades), conversions exist for comparing JIS/ISO grades to AGMA standards. Why is Obtaining the JIS B 1702-1 PDF Important?

To truly understand JIS B 1702-1, it is essential to look at its history. Before its introduction, gear accuracy in Japan was governed by , which classified gears into nine grades (0 to 8).

Precise definitions of gear deviations (e.g., pitch deviations, profile deviations, lead deviations). The difference between the actual and theoretical tooth

: The standard is available for purchase from authorized standards retailers like the JSA web store, Intertek Inform, and other global distributors. As the latest definitive version is the 2016 edition, it is recommended that you always verify you are obtaining the most recent version.

Accessing the official PDF document is crucial for engineering workflows due to several functional requirements:

As a copyrighted publication, obtaining the official PDF comes with important considerations.

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.
