This standard provides information on the design of spur and helical vehicle power transmission gears. Included are considerations for design, material and heat treatment, lubrication, determination of load capacity, mounting features, and typical design problems.
In determining load capacity, the knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and operating gear units. This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for the rating factors. It is not intended for use by the engineering public at large.
Vehicle gearing is defined as: “Steel drive line components of self-propelled, wheeled or non-wheeled vehicles; for transportation, recreational or industrial use. Propulsion of these vehicles should be a primary function of its power source, and its mobility not confined to the constraints of a closely defined area.”
[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 ANSI/AGMA Standard 6102-D20, Design Guide for Vehicle Spur and Helical Gears (Metric Edition).]
The decision to produce a vehicle gearing design guide was made by the Vehicle Gearing Committee on May 4, 1971. The first draft of AGMA 170.01 was dated May 1972. AGMA 170.01 was approved by the AGMA membership in February 1976.
The Vehicle Gearing Committee was reactivated in October 1987 to develop an updated vehicle gearing design guide. ANSI/AGMA 6002-B93 updates, expands, and replaces AGMA 170.01
ANSI/AGMA 6002-B93 was published in 1993.
ANSI/AGMA 6102-C15 updates, expands, and replaces ANSI/AGMA 6002-B93. The standard has been completely rewritten with updated material throughout. A sample of the changes to the standard include:
– Metric conversion of ANSI/AGMA 6002-C15;
– New sections on macro gear tolerances and high contact ratio gears;
– A new chapter on surface finish;
– An expansion of lubrication considerations from one section to an entire chapter;
– A complete rewrite of the load capacity section so that the material is more in line with the ANSI/AGMA 2101-D04;
– Four new annexes were created that include: a design example; vehicle gearing equations; a discussion of splines; and an annex on lubrication considerations for planetary carriers.
ANSI/AGMA 6102-D20 has the following updates:
– Nomenclature for gear tooth failure modes has been made consistent with ANSI/AGMA 1010-F14.
– Nomenclature and symbols for gear geometry made consistent with ANSI/AGMA 1012-G05.
The first draft of ANSI/AGMA 6102-D20 was made in December 2017. It was approved by the AGMA membership in September 2019. It was approved as an American National Standard on February 06, 2020.
