Design and Selection of Components for Enclosed Gear Drives
This standard provides an acceptable practice for the design and selection of components for enclosed gear drives. Fundamental equations provide for the proper sizing of shafts, keys, and fasteners based on stated allowable stresses. Other components are discussed in a manner to provide an awareness of their function or specific requirements. This standard applies to the following types of commercial and industrial enclosed gear drives, individually or in combination: spur, helical, herringbone, double helical, or bevel gearing in single or multiple stages. Bevel gear drives may include shaft angles other than 90 degrees.

AGMA 260.02 was approved by the AGMA membership on February 1, 1973 and issued in January of 1974. It consolidated with minor revision, information contained in the following superseded AGMA Standards:
AGMA 255.02 (November 1964), Bolting (Allowable Tensile Stress) for Gear Drives;
AGMA 260.01 (March 1953), Shafting – Allowable Torsional and Bending Stresses;
AGMA 260.02, also incorporated allowable stresses for keys;
AGMA 265.01, Bearings – Allowable Loads and Speeds.
The purpose of ANSI/AGMA 6001-C88, as a replacement for AGMA 260.02, was to establish a common base for the design and selection of components for the different types of commercial and industrial gear drives.
ANSI/AGMA 6001-C88 was expanded to include a generalized shaft stress equation which included hollow shafting, miscellaneous components, housings, and keyway stress calculations. All design considerations were revised to allow for 200 percent peak load for helical, spiral bevel, spur and herringbone gearing, and 300 percent peak load for wormgearing. The bearing section was updated to include consideration of life adjustment factors, bearing lives other than 5000 hours and reliability levels other than L10.
During the preparation of ANSI/AGMA 6001-C88, a considerable amount of time was spent on the shaft design section in an effort to include the most recent theories on shaft stresses and material characteristics. The standard included the existing practice for shaft design, and for reference purposes, appendix C included a description of, and excerpts from, ANSI/ASME B106.1M, Design of Transmission Shafting, published in 1985 .
ANSI/AGMA 6001-C88 was approved by the membership in May 1988 and approved as an American National Standard on June 24, 1988.
ANSI/AGMA 6001-D97 was expanded to include more recent theories on shaft design and analysis. Also, equations for shaft deformation were added. ANSI/AGMA 6001-D97 was approved by the membership in October 1996 and approved as an American National Standard on August 7, 1997.
ANSI/AGMA 6001-E08 was updated as required by ANSI practices. In the process, several improvements and simplifications were included. Minimum material requirements were added for shaft material and the shaft deflection clause was moved to an annex. Also, the clauses on keys and fasteners were revised to reflect current practices with higher allowable stresses in some cases.
The first draft of ANSI/AGMA 6001-E08 was made in August 2002. It was approved by the AGMA membership in September 2008. It was approved as an American National Standard on December 19, 2008.
ANSI/AGMA 6001-F19 was reviewed and updated in accordance with ANSI practices, with general updates and corrections that accumulated since publication of E08. In particular, Clause 8, Housings, was expanded to include graphics and discussion of stress analysis. Also, Clause 10, Miscellaneous components, was significantly upgraded in content.
The first draft of ANSI/AGMA 6001-F19 was made in April 2018. It was approved by the AGMA membership in December 2018. It was approved as an American National Standard on January 18, 2019.
