Evaluation of profile and helix deviations using second-order analysis. Annex C: Filtering methods for profile and helix data. Annex E: Runout evaluation guidelines. 5. Conclusion
The updated standard inverted and expanded the scale. It introduces , where:
It provides the numerical data needed to verify that manufactured gears meet design specifications. jis b 1702-1 pdf
. 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
Engineers and technicians seek the PDF version for several practical reasons: to ensure compliance with modern standards.
represents the highest level of manufacturing precision. Grade 12 represents the lowest tier of precision.
The "1" in JIS B 1702-1 is crucial. Part 1 deals with the definition of tolerances . Part 2 (JIS B 1702-2) deals with the measurement and inspection of those errors. You need both for a complete quality control system, but Part 1 is the foundation. ranging from (highest precision
It is crucial to use the most recent version, such as , to ensure compliance with modern standards.
The Jis B 1702-1 pdf outlines several key components for evaluating the accuracy of gear teeth, including:
