Aagma was founded in by nine companies in response to the market demand for standardized gear products; it remains a member– and market–driven organization to this day. AGMA provides a wide variety of services to the gear industry and its customers and conducts numerous programs which support these services.

Some of these services and programs are: AGMA develops all U. This is the only trade show dedicated solely to the gear industry. Enrollment is open to all. May Out of print or obsolete documents are available only by contacting AGMA Headquarters directly It focuses only on the gear industry.

More specifically, it focuses on those opportunities you might miss as you deal with the everyday demands of gear manufacturing. On your behalf, the Foundation explores the new ideas, the outside–the–box approaches, and the cutting edge technologies that could transform your future.

This information sheet discusses how noise measurement and control depend upon the individual characteristics of the prime mover, gear unit, and driven machine, as well as their combined effects in a particular acoustical environment. It indicates certain areas that might require special attention. This document is a revision of AGMA Typical applications using smooth prime movers and special considerations involving unusual or more severe loading are discussed.

Update of AGMA AGMA standards for gear load capacity agmma require allowable stress numbers related to material grade, which are based on type and heat treatment. For 420.40 heat treatment method and AGMA grade number, acceptance criteria are given for various material sgma identified in this document. Discussions include such topics as methods for defining datum axes on components; the use of center holes and mounting surfaces during manufacturing and inspection; and, recommended values of in–plane and out–of–plane deviations of shaft parallelism.

AGMA A03 Effect of Agm on Gear Surface Distress Provides guidance for the design of spur and helical gearing of 20 through diametral pitch including internal and rack forms. Manual contains such specialized subjects as inspection, lubrication, gear load calculation methods, materials, including a wide variety of plastics.

This document provides currently available information pertaining to oil lubrication of industrial gears for power transmission applications. It is intended to serve as a general guideline and source of information about gear oils, their properties, and their tribological behavior in gear contacts. Equations provided allow the calculation of specific film thickness and instantaneous contact flash temperature for gears in service, and to help assess the potential risk of surface distress scuffing, micropitting and macropitting, and scoring involved with a given lubricant choice.

This document is not intended to be a practice for any gears other than those applied to aerospace. Provides numerical examples for calculating the pitting atma geometry factor, I, and bending strength geometry factor, J, for typical gearsets that are generated by rack– type tools hobs, rack cutters May Pages: The iterative solution agka is described is compatible with the definitions of the term face load distribution of AGMA standards and longitudinal load distribution of the ISO standards.

The procedure is easily programmable and flow charts of the calculation scheme, as well as examples from typical software are presented. This standard provides nomenclature for general modes of gear tooth wear and failure.

It classifies, identifies and describes the most common types of failure and provides information which will, in many cases, enable the agmma to aga failure modes and evaluate the degree or progression of wear.

Provides guidelines for the alignment of such instrument elements as centers, ways and probe systems. The instrument accuracy requirements needed to meet the accuracy of product gears is discussed. It also covers the application of gear artifacts to determine instrument accuracy. This involved the calculation of U95 uncertainty at all steps from the artifact to the final product gears.

Defines a classification system for accuracy grades D through AAA, in order of increasing precision. The standard describes hob identification practices, manufacturing and purchasing considerations, and hob design parameters. An informative annex is included which provides the reader with a basic understanding of how the different elements of a hob can affect the accuracy of the agka being machined. Revision of AGMA aga It contains a description, with equations and sample calculations, of how the proportions of a spur afma helical gear may be derived from the design tooth thickness and the basic rack data.


In several annexes, there are discussions of possible variations from the ahma rack and also a procedure for defining tooth proportions without using the basic rack concept. Includes spur and helical gearing of 20 through diametral pitch with tooth proportions of 20 degree pressure angle and having 7 or more teeth. Tooth proportions shown may also be suitable for gear designs of finer than diametral pitch. It provides definitions for gear tooth accuracy terms, the structure of the gear accuracy system and the allowable values of pitch, profile and helix deviations.
