Comprehensive Guide to JIS B 1702-1: The Standard for Cylindrical Gear Accuracy

JIS B 1702-1 is a Japanese Industrial Standard, equivalent to ISO 1328-1, that defines classification and allowable deviation values for the tooth flanks of cylindrical involute gears, ranging in accuracy from grades 1 to 11. Updated in 2016, this standard covers spur and helical gears with reference diameters between 5 mm and 15,000 mm, focusing on critical parameters like pitch, profile, and helix deviations.

One of the most important facts about this standard is its international compatibility. jis b 1702-1 pdf

Many Asian manufacturers (especially in Japan, South Korea, and Taiwan) default to JIS standards. Having the PDF ensures seamless communication with overseas suppliers.

Historically, the JIS gear accuracy standard underwent a massive revision in 1998 to align itself closely with the International Organization for Standardization (ISO) framework, specifically . The modern JIS B 1702-1 standard focuses on elemental deviations of individual gear teeth rather than composite errors, providing a highly technical and precise methodology for gear inspection. Key Scope of the Standard Gear Types: Spur and helical cylindrical gears. Mating Configurations: Parallel axes.

The JIS B 1702 series is divided into multiple parts to address different measurement methods and materials: Accuracy of Gears | KHK Instead of looking for the standard itself, look

If you cannot find Part 1, look for Part 2 documents. Sometimes technical papers will include the geometric definitions from Part 2 alongside the stress definitions from Part 1 to provide a complete calculation example.

While the "JIS B 1702-1 PDF" is a protected, paid document, securing a copy from official channels is an essential investment for any engineer serious about precision manufacturing. By purchasing directly from JSA Webdesk or a reputable reseller, you ensure you have the latest, accurate, and legally compliant data for your gear design and inspection needs. Always verify the revision before purchasing, and remember that investing in the legal standard is an investment in the safety and reliability of your mechanical systems.

The modern JIS B 1702 series splits gear evaluation metrics across three distinct focus areas: Jis B 1702-2 | PDF - Scribd Updated in 2016, this standard covers spur and

: Since it is identical to ISO 1328-1, the ISO version is often used interchangeably in international trade. Gear Manufacturers

It’s also worth noting that a gear's final quality often involves other complementary standards. For example, while JIS B 1702-1 specifies the tooth accuracy, the dimensional tolerances for features like the shaft bore often adhere to another standard, , Class m (intermediate), to ensure the overall component is properly defined .

Here's an informative review of the standard:

: The old system used Grades 0 through 9 (with 0 being the best). The new system (1702-1) aligns with ISO, where is far more precise than the old Grade 0. Calculation
