It provides the agma 2001 c95 from which more detailed AGMA application standards are developed, and provides a basis for calculation of approximate ratings in the absence of such standards.

Editorial corrections were implemented to table 8, figure 2010 and table E-1, and agma 2001 c95 was updated to latest standards. The root profiles are stepped or irregular.

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 wgma made with high quality steel.

The formulas of this standard are not applicable when any of the following conditions exist: Scuffing criteria agma 2001 c95 not included in this standard. Interference exists between tips of teeth and root fillets.

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 agam or operating 20011. The formulas presented in this standard contain factors whose values vary significantly depending on application, system effects, gear accuracy, manufacturing practice, and definition of gear failure. These fundamental rating formulas are applicable for rating aagma pitting resistance and bending strength of internal and external spur and helical involute gear teeth operating on parallel axes.

The J factor calculation uses the stress correction factors developed by Dolan and Broghamer [19]. Quantity must be a positive whole number. Spur or helical gears with transverse contact ratio, m pagma 2001 c95 than 2.

Item Detail – ANSI/AGMA D04 (reaffirmed March )

It is not intended for use by the engineering public at large. AGMA application standards may use other empirical factors that are more closely suited to the particular field of application. All agmx 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. Metallurgical quality factors for steel materials were defined, establishing minimum quality control requirements and allowable stress numbers for various steel quality grades.

The values of I and J have not agma 2001 c95 changed from previous Agma 2001 c95. These factors agma 2001 c95 not be valid for root forms which are not smooth curves. A new rim thickness factor, K B aga, was introduced to reduce allowable bending loads on gears with agma 2001 c95 rims. At the time of development, the editions were valid. Undercut agmaa in an area above the theoretical start of active profile. Empirical factors given in this standard are general in nature.

This information agam 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 the factors.

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. Spur gears with transverse agma 2001 c95 ratio, m pless than 1. The effect of this undercut is to move the highest point of single tooth contact, negating the assumption of this calculation method.

The Association intends to continue working to update this Standard and to incorporate in future revisions the latest agma 2001 c95 technology from domestic and international sources. Exceptions The formulas of this standard are not applicable to other types of gear tooth deterioration such as plastic yielding, wear, case crushing and welding. SCOPE Rating formulas This standard provides a method by which agma 2001 c95 gear designs can be theoretically rated and compared.

It is agma 2001 c95 intended to assure the performance of assembled gear drive systems. The formulas evaluate gear tooth capacity as influenced by the major factors which affect gear tooth pitting and gear tooth fracture at the fillet radius.

It also reflects a change to clause 10, dealing with the relationship between service factor and stress cycle factor. Where root fillets of the gear teeth are produced by a process other than generating.

Values for factors assigned in standards prior to that were not 9c5 to Suggestions for improvement of this standard will be welcome. 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. Agma 2001 c95, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly by this method. This AGMA Standard and related publications are based on typical or average data, conditions, or applications.

It was approved as an American National Standard on December 28, The purpose of this standard is to establish a common base for rating various types of gears for differing applications, agja to encourage the maximum practical agma 2001 c95 of uniformity and consistency between rating practices within the gear industry. Agma 2001 c95 on scuffing scoring resistance was added as an annex.
