AGMA 6013-A06 PDF

This standard is applicable to enclosed gear drives including configurations of parallel, concentric and right angle shafts. It includes foot mounted, shaft mounted, screw conveyor drives and gearmotors. These enclosed drives utilize spur, helical, herringbone, double helical, or bevel gearing in single or multistage, and may include wormgearing in multistage drives. Bevel gear drives may include shaft angles other than 90 degrees.

Limitations

This standard is applicable to gear drives having single or multiple stage gearing with pitch line velocities not exceeding 7000 ft/min for spur, helical, and spiral bevel gearing and 6000 ft/min for straight bevel, spiral bevel and wormgearing, and component speeds not exceeding 4500 rpm for helical, spur, straight bevel and spiral bevel gearing and 3600 rpm for wormgearing. Wormgearing operating at sliding velocities greater than 2000 ft/min may require special lubricants, pressurized systems or both.

Exceptions

This standard does not cover epicyclic or crossed-- helical gear drives. This standard does not cover the rating of spur, helical or bevel gears due to wear or scuffing. The design and rating of the electric motor is beyond the scope of this standard. This standard does not apply to gear drives that are covered by other specific AGMA application standards.
