ABSTRACT

This information sheet discusses inspection of cylindrical involute gears using the radial (double flank) composite method, with recommended practices detailed. This information sheet is a supplement to the standard ANSI/AGMA 2015-2.

SCOPE

This information sheet constitutes a code of practice dealing with inspection relevant to radial composite deviations of gears when measurements are made by using a master gear in double flank contact.

In providing advice on gear checking methods and the analysis of measurement results, it supplements standard ANSI/AGMA 2015-2.

NOTE: Measurements by using a master gear in single flank contact are not covered by this information sheet. See ANSI/AGMA/ISO 1328-1 [1] and ISO/TR 10064-1 [2], for more information on single flank testing.

FOREWORD

[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of AGMA 915-2-B20, Inspection Practices – Part 2: Double Flank Radial Composite Measurements.]

AGMA 915-2-A05 replaced AGMA ISO 10064-2, Cylindrical Gears – Code of Inspection Practice – Part 2: Inspection Related to Radial Composite Deviations, Runout, Tooth Thickness and Backlash, and the information on similar subjects as covered in AGMA 2000-A88, Gear Classification and Inspection Handbook – Tolerances and Measuring Methods for Unassembled Spur and Helical Gears.

The first draft of AGMA 915-2-A06 was made in March 1999. It was approved by the Technical Division Executive Committee (TDEC) in May 2005.

The AGMA 915-2-B20 revision replaces AGMA 915-2-A05 and was approved by the Technical Division Executive Committee (TDEC) on November 26, 2019. The main changes in this new revision include:

• Change of title;
  • OLD - Inspection Practices - Part 2: Cylindrical Gears - Radial Measurements;
  • NEW - Inspection Practices – Part 2: Double Flank Radial Composite Measurements;
• Addition of other types of gears including bevel gears;
• Information on the measurement of double flank runout, eccentricity, functional tooth thickness and higher order Fourier Analysis;
• Design of suitable master gears, statistical measurement techniques related to the use of double flank testers, gage repeatability and reproducibility and uncertainty analysis.
