This standard is applicable to enclosed gear drives includingconfigurations of parallel, concentric and right angle shafts. Itincludes foot mounted, shaft mounted, screw conveyor drives andgearmotors. These enclosed drives utilize spur, helical,herringbone, double helical, or bevel gearing in single ormultistage, and may include wormgearing in multistage drives. Bevelgear drives may include shaft angles other than 90 degrees.
Limitations
This standard is applicable to gear drives having single ormultiple stage gearing with pitch line velocities not exceeding7000 ft/min for spur, helical, and spiral bevel gearing and 6000ft/min for straight bevel, spiral bevel and wormgearing, andcomponent speeds not exceeding 4500 rpm for helical, spur, straightbevel and spiral bevel gearing and 3600 rpm for wormgearing.Wormgearing operating at sliding velocities greater than 2000ft/min may require special lubricants, pressurized systems orboth.
Exceptions
This standard does not cover epicyclic or crossed– helical geardrives. This standard does not cover the rating of spur, helical orbevel gears due to wear or scuffing. The design and rating of theelectric motor is beyond the scope of this standard. This standarddoes not apply to gear drives that are covered by other specificAGMA application standards.
