Item Detail – ANSI/AGMA D04 (reaffirmed March )

This method is recommended for plastics with normal toothing. A new rim thickness factor, K Bwas introduced to reduce allowable bending loads on gears with thin rims. It also reflects a change to clause 10, dealing with the relationship between service factor and stress cycle factor. The root profiles are stepped or irregular.

The purpose of this standard is to establish a common base for rating various types of gears for differing applications, and to encourage themaximum practical degree of uniformity and consistency between rating practices within the gear industry. Agam 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.

Method B is used for this calculation. The Y J factor calculation uses the stress correction factors developed by Dolan and Broghamer [19]. The formulas of this standard are not applicable when any of the following conditions exist: For root profiles which are stepped or irregular, other stress correction factors may be more appropriate. It was approved as an American National Standard on December 28, However, this also involves a ahma of special features.

Undercut exists in an area above the theoretical start of active 2101-x04. Where root fillets of the gear teeth are produced by a process other than generating.

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. This AGMA Standard and related publications are based on typical or average data, conditions, or applications. This calculation can also be used for every other cylindrical gear configuration including planetary stages.

It includes all methods described in sheet 2 of VDI empirical calculation, tooth root, tooth flank, deformation, wear. VDI contains all the modifications recommended according to Tables All publications are agmw to revision, and the users of this standard are encouraged to investigate the possibility of applying the most recent editions of the publications listed.

Additional higher allowable stress numbers for carburized gears were added when made with high quality steel. The following values are also output in addition to all the relevant intermediate results: However, some factors have been specifically defined for special applications.

See table in Material on scuffing scoring resistance was added as an annex.

It is not intended for use by the engineering public at large. Metallurgical quality factors for steel materials were ayma, establishing minimum quality control requirements and allowable stress numbers for various steel quality grades.

Scuffing criteria are not included in this standard.

If the Rating module is not selected in the Calculation menu, only the geometry is calculated. AGMA application standards may use other empirical factors that are more closely suited to the particular field of application.

However, the reduction in tooth root thickness due to protuberance below the active profile gama handled correctly by this method. You must enter two application factors to represent load spectra accurately. Quantity must be a positive whole number. To perform the calculation correctly, you must use our information sheet which describes the necessary checks and inputs: 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 2101-d0.

Suggestions for improvement of this standard will be welcome. The previous version of the AGMA standard has been retained because many companies still use old versions 1201-d04 the guidelines. 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 arrangement etc. Interference exists between tips of teeth and root fillets. This calculation is also performed using Method B.

Take the following notes into account, see Agmz The effect of this undercut is to move the highest point of single tooth contact, negating the assumption of this calculation method.

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. It is not intended to assure the performance of assembled 2101-d40 drive systems.

Otherwise, use Method B. Differs only slightly from the previous version, C This regulation defines how calculations are performed on gears made of plastic or combinations of plastic and steel.

Plastic as defined in Niemann Please refer to [ 65 ] and Table In this calculation method, the tooth form factor Y F is calculated according to Method C. This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for the factors.

Unlike DIN which, for example, has a specific method for static shaft calculations, ISO does not have its own 2101-r04 method for static calculation. Values for factors assigned in standards prior to that were not applicable to SCOPE Rating formulas This 2101d04 provides a method by which different gear designs can be theoretically rated and compared. In fact, there are very few differences between the old edition, B88, and the new edition, C
