Inspection Practices – Part 2: Double Flank Radial Composite Measurements

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.

Suggestions for improvement of this information sheet will be welcome. They should be sent to tech@agma.org
