This part of ANSI/AGMA 2015 establishes a system of accuracy relevant to radial composite deviations of individual cylindrical involute gears. It specifies the appropriate definitions of gear tooth accuracy terms, the structure of the gear accuracy system and the allowable values of the above mentioned deviations. The radial measurement accuracy system has different grade ranges than the elemental ranges in ANSI/AGMA 2015--1--A01. The diameter and module ranges for radial composite deviations and runout are also different. The radial composite accuracy system comprises 9 accuracy grades for total or tooth--to--tooth radial composite deviations of which grade C4 is the most accurate and grade C12 is the least accurate. This standard is for the ranges: 0.2 ≤ mn ≤ 5 2 mm≤ d ≤ 1000 mm 3 ≤ z ≤ 1000 β ≤ 45° where mn is normal module; d is reference pitch diameter; z is number of teeth; β is helix angle. See clause 7 for tolerances. AnnexAprovides information onmaster gear design and tolerances. Annex B provides information on runout, including an equation for determining the tolerance, for use if agreed upon between manufacturer and purchaser. There is no correlation between accuracy grades of elemental measurements specified by ANSI/AGMA 2015--1--A01 and radial composite measurements.
