However, it does have some significant differences, especially where S-N curves Woehler lines are concerned.

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

For root profiles which are stepped or irregular, other stress correction factors may 2101-d044 more appropriate. 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.

Proper evaluation of these factors is essential for realistic ratings.

AGMA also provides information to help you select the application factor KA for specific turbo-driven applications and other useful notes about this type of gear lubrication 2101d-04 etc. Where root fillets of the gear teeth are produced by a process other ama generating. The standard is implemented in its entirety, and the dynamic factor and the face load factor are calculated according to AGMA recommendations.


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. Lloyd’s register, classification for ships Calculation guideline for ships’ gears 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.

A new zgma thickness factor, K Bwas introduced to reduce allowable bending loads amga gears with thin rims. It was approved as an American National Standard on December 28, This regulation defines how calculations are performed on gears made of plastic or combinations of plastic and steel. The previous version of the AGMA standard has been retained because many companies still use old versions of the guidelines.

The Y J 201-d04 calculation uses the zgma correction factors developed by Dolan and Broghamer [19]. Plastic according to VDI The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and operating gear units.

However, the new edition does include the service factor calculation. In this case, less complex means that some data is already predefined.

Most recent version of AGMA Additional higher allowable stress numbers for carburized gears were added when made with high quality steel.

Tooth flank fracture calculation method. This calculation can also be used for every other cylindrical gear configuration including planetary stages.


In this situation, the program checks whether all the constraints are set and, if not, displays a prompt asking the user if they want to make any modifications. Differs only slightly from the previous version, C SCOPE Rating formulas This standard provides a method by which different gear designs can be theoretically rated and compared. These calculation methods are based on the AGMA or basic standards.

This calculation is also performed using Method B. Values for factors assigned in standards prior to that were not applicable to See table in The root profiles are stepped or irregular.

This method is recommended for plastics with normal toothing. However, some factors have been specifically defined for special applications. This standard presents general formulas for rating the pitting resistance and bending strength of spur and helical involute gear teeth using ISO symbology and SI units, and supersedes AGMA C It is not intended for use by the engineering public at large.

However, the reduction in tooth root thickness due to protuberance below the active profile is handled correctly by this method. Otherwise, use Method B. However, it is remarkable that the AGMA standard does not permit tooth root strength to be calculated directly in internal gear pairs.
