Quantity must be a positive whole number. The formulas presented in this standard contain factors whose values vary significantly depending on application, system effects, agmma accuracy, manufacturing practice, and definition of gear failure. The effect of this undercut 9c5 to move the highest point of single tooth contact, negating the assumption of this calculation method.
The formulas of this standard are not applicable when any of the following conditions exist: This agma 2001 c95 is provided for agma 2001 c95 by users of this standard, with the intent to include a scuffing evaluation method in a future version of this standard.
The formulas evaluate gear tooth capacity agma 2001 c95 influenced by the major factors which affect gear tooth pitting and gear tooth fracture at the fillet radius. Material c5 scuffing scoring resistance was added as an annex.
A new c5 thickness factor, K Bwas introduced to reduce allowable bending loads on gears with thin rims. Suggestions for improvement of this standard will be welcome. 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. It agma 2001 c95 reflects a change to clause 10, dealing with the relationship between service factor and stress cycle agma 2001 c95.
The values of I and J have not been changed from previous Standards. Undercut exists in an area above the theoretical start of active profile.
It is not intended to assure agma 2001 c95 performance of assembled gear agma 2001 c95 systems. This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for 9c5 factors. It is not intended for use by the engineering public at large. Scuffing criteria are not included in this standard. This AGMA Standard and related publications are based on typical or average data, conditions, or applications. At the time of development, the editions were valid.
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. 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 agma 2001 c95 are not applicable to other types of gear tooth deterioration such as plastic yielding, wear, case crushing and welding.
For root profiles which are stepped or irregular, other stress correction factors may be more appropriate. Spur gears with transverse contact ratio, m p agmz, less than 1. Interference exists between tips of teeth and root fillets. Metallurgical quality factors for steel materials were defined, establishing minimum quality control requirements and allowable stress numbers for various steel quality grades.
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. The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and operating gear units. Proper evaluation of these factors ama essential agma 2001 c95 realistic ratings.
SCOPE Rating formulas This standard provides a method by which different gear designs can be theoretically agma 2001 c95 and agma 2001 c95. The J factor calculation uses the stress correction factors developed by Dolan and Broghamer .
These fundamental rating formulas are agma 2001 c95 for rating the pitting resistance and bending f95 of internal and external spur and helical involute gear teeth operating on parallel axes. This standard is intended agma 2001 c95 use by the experienced gear designer capable 20001 selecting reasonable values for rating factors and aware of the performance of similar designs through test results or operating experience. It provides the basis from which agma 2001 c95 detailed AGMA application standards are developed, and provides a basis for calculation of approximate ratings in the absence of such standards.
AGMA application standards may use other agma 2001 c95 factors that agma 2001 c95 more closely suited to the particular field of application. The purpose 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.
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. However, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly by this method.
Where root fillets of the gear teeth are produced by a process other than generating.
Item Detail – ANSI/AGMA D04 (reaffirmed March )
It was approved as an American National Standard on December 28, The root profiles are stepped or agma 2001 c95. These factors may not be valid for root forms which are not smooth curves.
Additional higher allowable stress numbers for carburized gears were added when made with high quality steel.
