23、Design Manual for Enclosed Epicyclic Gear Drives.This standard presents design information and rating methods for epicyclic enclosed geardrives. This standard supersedes ANSI/AGMA 6023-A88 and ANSI/AGMA 6123-A88.The initial AGMA publication that addressed epicyclic gearing was a portion of AGMA420.0

24、4, Practice for Enclosed Speed Reducers or Increasers Using Spur, Helical,Herringbone and Spiral Bevel Gears. It was published in 1975, but was subsequentlysupersededby ANSI/AGMA6123-A88,DesignManualfor EnclosedEpicyclic GearDrives,a much more comprehensive epicyclic gear document, published in 1988

25、.AGMA reactivated the Epicyclic Gear Committee to develop a revision to ANSI/AGMA6123-A88 that would incorporate additional guidelines, the latest gearing technology asapplied to epicyclic gears, and SI units exclusively.The purpose of this standard is to provide the user of enclosed epicyclic gear

26、drives with amethod of specifying and comparing proposed designs to help predict the relativeperformance of different units. This standard is intended to establish a common base forrating epicyclic gear units and to encourage the maximum practical degree of uniformity andconsistency between rating p

27、ractices in the gear industry. It emphasizes the complexity ofepicyclic unit design, and the need to consider the entire system of housings, bearings,gears and shafts in establishing the rating of a drive.The formulas presented in this standard contain numerous terms whose individual valuescan vary

28、significantly depending on application, system effects, accuracy, andmanufacturing methods. Proper evaluation of these terms is essential for realistic rating.The knowledge and judgment required to evaluate properly the various rating factorscomes primarily from years of accumulated experience in de

29、signing, testing,manufacturing, and operating similar gear units. The detailed treatment of the generalrating formulas for specific product applications is best accomplished by those experiencedin the field.The first draft of ANSI/AGMA 6123-B06 was created in September 2001. It was approvedby the me

30、mbership in March 2006 and as an American National Standard on September 20,2006.Suggestions for improvement of this standard will be welcome. They should be sent to theAmerican Gear Manufacturers Association, 500 Montgomery Street, Suite 350, Alexandria,Virginia 22314.Copyright American Gear Manufa
