24、or Marine Propulsion Gearing.The purpose of ANSI/AGMA 6033-C08 is to provide alloy steel specifications and qualityassurance measures for pinions and gears used in main propulsion marine applications.This document consolidates and adapts the material specifications generally used forpinions and gear
25、s in the defined marine propulsion applications.ANSI/AGMA 6033-A88 was proposed to the Technical Division Executive Committee in1979 by the Chairman of the Marine Gearing Committee. Interest in, and the need for thisstandard was expressed at a committee meeting in February 1980. Work began on rolled
26、ring forgings for rims of large fabricated gears. Metallurgists from several membercompaniesattendedthatandsubsequentmeetings. Thecommitteecontinuedworkonthestandard,expandingthecontentstoincludeotherformsofgearing,propertiesofcommonlyavailable alloy steels, heat treatment methods and inspection req
27、uirements.The Marine Gearing Committee submitted the standard,and itwas approved by the entireAGMA membership in its final edited version in March 1988. On May 31, 1988 it wasapproved as an American National Standard.In late 1993 the AGMA Technical Division Executive Committee recommended that theMa
28、rine Gearing Committee review and update ANSI/AGMA 6033-A88, Standard forMarine Propulsion Gear Units, Part 1, Materials. This review and update was initiated inearly1994.
