C

3、onsensus 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 an

Th

31、is standard presents formulas and information using ISO symbology and SI units. AGMA 321.01 was originally developed to cover gears used primarily for ball and rod mills, and for kilns and dryers. It was approved in October 1943, and later modified in June 1946. In June 1951, AGMA 321.03 was approve

32、d as a standard. Further changes and additions were approved in June 1959, and AGMA 321.04 was issued in March 1960. AGMA 321.05 was approved in March 1968 and issued in March 1970. In February 1979, the Mill Gearing Committee was reorganized to review AGMA 321.05 and revise it in accordance with AG

33、MA 218.01, Rating the Pitting Resistance and Bending Strength of Spur and Helical Involute Gear Teeth. With AGMA 218.01 as a guide, the committee submitted the first draft of ANSI/AGMA 6004-F88 in March 1984. ANSI/AGMA 6004-F88 superseded AGMA 321.05, Design Practice for Helical and Herringbone Gear

34、s for Cylindrical Grinding Mills, Kilns, Coolers, and Dryers. It was approved by the AGMA membership in January 1988 and approved as an American National Standard on May 31, 1988. ANSI/AGMA 6004 was not widely accepted by the industry and many continued to use AGMA 321.05. As such, the AGMA Mill Gea

35、ring Committee began work on ANSI/AGMA 6114-A06 in November 2001. Changes to the standard include a new dynamic factor analysis as a function of transmission accuracy number, revised allowable stress numbers, the use of the stress cycle factor in the rating practice, and ratings for gears made from

36、ductile iron. Extensive discussions on new equipment installation and alignment, lubrication, and use of ausferritic ductile iron (ADI) were added to the annex. The AGMA Mill Gearing Committee began work on AGMA 6114-B15 in February 2011. Changes to the standard, based on committee experience and fi

37、eld performance of gear sets, include: - added load distribution factor for self-aligning pinions; - modified values of FPfor ductile iron and ADI; - reformatted graph of minimum effective case depth for carburized and induction hardened pinions, he min; - moved austempered (formerly ausferritic) du

38、ctile iron from Annex H to the body of the standard; - revised Annex D to include information taken from ANSI/AGMA 9005-E02 8; - changed references to extreme pressure (EP) additives to antiscuff (AS) additives in Annex D. Users are encouraged to transition their terminology away from the term extre

39、me pressure, or EP, and toward antiscuff, or AS; - updated material mechanical property information in Annex F; - added Annex J to provide information on combination drives. Values for factors assigned in other standards are not applicable to this standard, nor are the values assigned in this standa

40、rd applicable to other standards. The ability to design gears, and the knowledge and judgment required to properly evaluate the various rating factors comes primarily from years of accumulated experience in gearing. The detailed treatment of the general rating formulas for specific applications is b

41、est accomplished by those experienced in the field. The first draft of AGMA 6114-B15 was made in September, 2012. It was approved by the AGMA membership in August 2015 and approved as an American National Standard on October 21, 2015. Suggestions for improvement of this standard will be welcome. The
