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 exceeding 35m/s for spur, helical, and spiral bevel gearing and 30 m/s forstraight bevel, spiral bevel and wormgearing, and component speedsnot exceeding 4500 rpm for helical, spur, straight bevel and spiralbevel gearing and 3600 rpm for wormgearing. Wormgearing operatingat sliding velocities greater than 10 m/s may require speciallubricants, pressurized systems or both.
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.
