ANSI AGMA 2001 C95 PDF

The Association intends to continue working to update this Standard and to in future revisions the latest acceptable technology from domestic and international sources. 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. Proper evaluation of these factors is essential for realistic ratings. 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.

ANSI C Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.

The use of American National Standards is completely voluntary; their existence does not any respect in preclude anyone, whether he hasapproved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, procedures not conforming the standards.

Moreover, no person shall have right or authority to the issue an interpretation of an American National Standard the name of the American National Standards in Institute. Requestsforinterpretation of thisstandardshouldbeaddressed to the American Gear Manufacturers Association. Any person who refersto an AGMA Technical Publication shouldbe sure that the publication is the latest available from the Association on the subject matter. Abstract This standard specifies a method for rating the pitting resistance and bending strength of spur and helical involute gear pairs.

A detailed discussionof factors influencing gear survival and calculation methods are provided. I and J S and SF ZN and YN. Hardness ratio factor. CH throughhardened. Instantaneous contact lines in the plane of action Pinion proportionfactor.

C Applicationanalysis D Discussion of the analytical face or longitudinal load distribution factor E Gear material fatigue life F Controlling section size considerations through hardened gearing The purpose of this standard is to establish a common base for rating various types gears for differing of applications, and encourage the maximum practical degree uniformity and consistency between rating to of practiceswithinthe gear industry, It providesthebasisfromwhich moredetailed AGMAapplication standards are developed, and provides a basis for calculation of approximate ratings the absence of such standards.

Proper evaluation of thesefactorsisessentialforrealisticratings. Thisstandardisintended for usebythe 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.

In AGMA Values for factors assigned in standards to that were not applicable prior to 21 8. Metallurgical quality factors for steel materials were defined, establishing minimum quality control requirements and allowable stress numbers for various steel quality grades. Additional higher allowable stress numbers for carburized gears were added when made with high quality steel.

A new rim thickness factor, was introducedto reduce KB, allowable bending loads on gears with rims. Material on scuffing scoring resistance was added an thin as annex. The Association intends to continue working update this Standard and to to incorporate in future revisions the latest acceptable technology from domestic and international sources.

SCOPE Rating formulas This standard provides a method by which different gear designs can be theoretically rated and compared. It is not intended to assure the performance of assembled gear drive systems. 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 on parallel axes. 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. The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufacturing, and operating gear units.
