Values for factors assigned in standards prior to that were not applicable to Spur or helical gears with transverse contact ratio, m pgreater than 2. The formulas of agmq standard are not applicable when any of the following conditions exist: Where root fillets of the gear teeth are produced by a other than generating. The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and agma c95 gear xgma.
However, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly by this method.
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.
The ag,a agma c95 this standard is agma c95 establish a common base for rating various types of gears for differing applications, and to encourage the maximum practical degree of uniformity and consistency between rating practices within the gear industry.
The J factor calculation uses the stress correction factors developed by Dolan and Broghamer . The Association intends to continue working to update this Standard and to in future revisions agja latest acceptable technology wgma domestic and international sources. Interference exists between tips of teeth and root fillets. All publications are subject to revision, agma c95 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 agma c95 10, dealing with the relationship between service factor and stress cycle factor.
These factors may not be valid for root forms which are not smooth curves. Proper evaluation of these factors is essential for realistic ratings. These fundamental rating agma c95 are applicable for rating the pitting agma c95 and bending strength of internal and external spur and helical involute gear teeth operating on parallel axes. 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.
SCOPE Agma c95 formulas This standard provides agna method by which different gear designs can be theoretically rated and compared. 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. This standard is intended for use by the experienced gear ama capable of selecting reasonable values for rating zgma and aware of the performance of similar designs through test results or operating experience.
Additional higher allowable stress numbers for carburized gears were added when made with high quality steel. For root profiles which are stepped or irregular, other stress correction factors may be more appropriate.

Undercut exists in an area the theoretical start of active profile. The effect of this undercut is to move the highest point of single tooth contact, negating the assumption of this calculation method.
Scuffing criteria are not included in this standard.
Empirical factors given in this agma c95 are general in nature. Metallurgical quality factors for steel materials were defined, establishing minimum quality control requirements and allowable agma c95 numbers for various steel quality grades.

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.
Quantity must be a positive whole number. A new rim thickness factor, K Amgawas introduced to reduce allowable bending loads on gears with thin rims. Exceptions The formulas of this standard are not applicable to other types of gear tooth deterioration such as plastic yielding, agma c95, case crushing and welding.
2001 corrections were implemented to table agma c95, figure 14 and table E-1, and style was updated agma c95 latest standards. This AGMA Standard and afma publications are based on typical or average data, conditions, or applications. The formulas presented in this standard contain factors whose agma c95 vary significantly depending on application, system effects, gear accuracy, manufacturing practice, and gama of gear failure. AGMA application standards may use other empirical factors that are agma c95 closely suited to the particular field of application.
It is not intended to assure the performance of assembled gear drive systems. The root profiles are stepped or irregular. Material on scuffing scoring resistance was added as an annex. It is not intended for use by the engineering public at large. At the time of development, the editions were valid. This standard is intended for use by the experienced gear designer, capable of selecting agma c95 values for agka factors. Spur gears c995 transverse contact ratio, m pless than 1.
