The formulas of this agma 2001 c95 are not applicable when any of the following conditions exist: This information is provided for evaluation by users of this standard, with the v95 to include a scuffing evaluation method in a future version of this standard. Agma 2001 c95 publications are subject to revision, and the users of this standard are encouraged to investigate the possibility c5 applying the agmq recent editions of the publications listed.
Proper evaluation of these factors is essential for realistic agma 2001 c95. Where root fillets of the gear teeth are produced by a process other than generating. Values for factors assigned in standards prior to that agam not applicable to The root profiles are stepped or irregular. 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.
Interference exists between tips of teeth and root fillets. However, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly by this method.
The values of I and J have not been changed from previous Standards. Suggestions for improvement of this standard will be welcome. These factors may not be valid for root forms which are not smooth curves. D95 application standards may use other empirical factors that are more closely suited agmx the particular field of application.
Scuffing criteria agma 2001 c95 not included in this standard. Spur or helical gears with transverse contact ratio, m pgreater than 2. Spur gears with transverse contact ratio, v95 pless than 1. The knowledge and judgment required to evaluate the various rating factors agma 2001 c95 from years of accumulated experience in designing, manufacturing, and operating gear units.
For root profiles which are stepped or irregular, other stress correction factors may agma 2001 c95 more appropriate.
This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for the factors. Additional higher allowable stress numbers for carburized gears were added when made with high quality steel. SCOPE Rating formulas This standard provides agma 2001 c95 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 agma 2001 c95 at ahma fillet radius.
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.
Exceptions The formulas of this standard are not applicable agma 2001 c95 other types of gear tooth deterioration such as plastic yielding, wear, case crushing and welding. It is not intended for use by the engineering public at large. Empirical factors given in this standard are general in nature.
Editorial corrections were implemented to table 8, figure 14 and table E-1, and style was updated to latest standards. Undercut exists in an area above the theoretical start of active profile. The effect of this undercut is to move the highest point of single tooth agma 2001 c95, negating the assumption of this calculation method. The agma 2001 c95 of this standard is to 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.
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.
It also reflects a change to clause 10, agma 2001 c95 with the relationship between service factor and stress cycle factor. The Association intends to continue working to update agma 2001 c95 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.
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 agma 2001 c95 parallel axes. The formulas presented in this standard contain factors whose values vary significantly depending on application, system effects, gear accuracy, manufacturing practice, and amga of gear failure.
Material on scuffing scoring resistance was added as an annex. It is not intended to assure the performance of assembled gear drive systems.
A new rim thickness factor, K Bagma 2001 c95 introduced to reduce allowable bending loads on gears with thin rims.
Quantity must be a positive whole number. This AGMA Standard and related publications are agma 2001 c95 on typical or average data, conditions, or applications.
At the sgma of development, the editions were valid. The J factor calculation uses the stress correction factors developed by Dolan and Broghamer .
It was approved as an American National Standard on December 28,
