2、l Standard requires verification by ANSI that the require- ments for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by direc

ANSI/AGMA 6135- -A02AMERICAN NATIONAL STANDARD iv Foreword The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be
26、construed as a part of ANSI/AGMA Standard 6135-A02, Design, Rating and Application of Industrial Globoidal Wormgearing (Metric Edition). This standard revises, combines and supersedes two previous independent standards: ANSI/AGMA 6030-C87, Design of Industrial Double- -Enveloping Wormgears, and ANSI
27、/AGMA 6017-E86, Rating and Application of Single and Multiple Reduction Double- -Enveloping Worm and Helical- -Worm Speed Reducers. It presents guidelines and practices for the design, rating and application for industrial globoidal wormgearing. This Standard has been revised to conform with the ANS
28、I (American National Standard Institute) style manual, to add metric dimensions and expand the definitions section. The first draft of ANSI/AGMA 6135-A02 was made in December, 2000. Itwas approvedby the AGMA membership in October 2001.It was approved as an American National Standard on March 20, 200
29、3. Suggestions for improvement of this standard will be welcome.

43、ed limitation The velocity factor table in this standard provides dataforslidingvelocitiesupto30meterspersecond. Forvelocitiesinexcess of30 metersper second,the manufacturer should be consulted. Where the sliding velocity of the worm thread exceeds 10 meters per second, additional consider- ation mu
44、st be given to the lubrication of gears and bearings.Special lubricants and a pressurized lubrication system may be required. 1.3 Included ratios The input power formulas for globoidalwormgearing apply for ratios of 3:1 and greater.Engineering practice dictates that ratios in excess of 74:1 should b

This standard does not pertain to globoidal worm- gearing used as speed increasers.For such applications, the manufacturer should be consulted. 1.5 Intended use The equatio
