It agka approved as an Agma 2001 c95 National Standard on December 28, Scuffing criteria are not included in this standard. The J ag,a calculation uses the stress correction factors developed by Dolan and Broghamer [19].

AGMA application standards may use other empirical factors that are more agma 2001 c95 suited to the particular field of application.

The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and operating gear units.

Additional higher allowable stress numbers for carburized gears were added when made with high quality steel. Values for factors agma 2001 c95 in standards prior to that were not applicable to Material on scuffing scoring x95 was added as an annex.

Editorial corrections were implemented to table 8, figure 14 and table E-1, and style was updated to latest standards. Spur or helical gears with transverse contact ratio, m pgreater than 2. The formulas c5 gear tooth capacity as influenced by the major factors which affect gear tooth pitting and gear tooth fracture at the fillet radius.

It is not agma 2001 c95 for use by the agmma public at large. At the time of development, the editions were valid.

Empirical factors given in this standard are general in nature. Spur gears with transverse contact ratio, m agma 2001 c95less than 1. A new rim thickness factor, K B abma, was introduced to reduce allowable bending loads on gears with thin rims.

It provides the basis from which more detailed AGMA application standards are developed, and provides a basis for calculation of approximate ratings in the absence of such standards. Where root fillets of the gear teeth are produced by a process other than generating.

The effect of agma 2001 c95 undercut is to move the highest point of single tooth contact, negating the assumption of this calculation method.

The values of I and J agma 2001 c95 not been changed from previous Standards. The Association intends to continue working to update this Standard and to incorporate in future revisions the latest acceptable technology from domestic and international sources.

Metallurgical quality factors for steel materials were defined, establishing minimum quality control requirements and allowable stress numbers for various steel quality grades.

Item Detail – ANSI/AGMA D04 (reaffirmed March )

It is not intended x95 assure the performance of assembled gear drive systems. Exceptions The formulas of this standard are not applicable to other types of gear tooth deterioration such as plastic yielding, wear, agma 2001 c95 crushing and welding.

This information is provided for evaluation by users of this standard, with the intent to include a scuffing evaluation method in a future version of this standard. This standard is intended for use by the experienced gear designer capable of selecting reasonable values for rating factors and aware of the performance of similar designs through test results or operating experience.

Suggestions agma 2001 c95 improvement of this standard will be welcome. Undercut exists in an area above the theoretical agma 2001 c95 of active profile.

Interference exists between tips agma 2001 c95 teeth and root fillets. The formulas presented in this standard contain factors whose values vary significantly depending on agmx, system effects, gear accuracy, manufacturing practice, and definition of gear failure. This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for the factors.

SCOPE Rating formulas This standard provides a method by which different gear designs can be theoretically rated and compared. Quantity must be agma 2001 c95 positive agma 2001 c95 number. Proper evaluation of these factors is essential for realistic ratings.

For root profiles which are stepped or irregular, other stress correction factors may be more appropriate. However, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly 22001 this method. This AGMA Standard and related publications are based on typical or average data, conditions, or applications.

The purpose of this standard is to establish a agma 2001 c95 base for rating various types of gears ama differing applications, and to encourage the maximum practical degree of uniformity and consistency between rating practices within the gear industry.

The formulas of this agmz are not applicable when any of the following conditions exist: The root profiles are stepped or irregular.

Design considerations to prevent fractures emanating from stress risers on the tooth profile, tip chipping, and failures of the gear blank through the web or hub should be analyzed by general machine design methods. All publications are subject to revision, and the users of this standard are encouraged to investigate the possibility of applying the most recent editions of the publications listed.

It also reflects a change to clause 10, dealing with the relationship agma 2001 c95 service factor and stress cycle factor. These fundamental rating formulas are applicable for rating the pitting resistance and bending strength of internal and external spur and helical involute gear teeth operating on parallel agma 2001 c95.
