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 multiple stages. Bevel gear drives may include shaft angles other than 90 degrees.
This standard includes design, rating, lubrication, testing, and selection information for enclosed gear drives, including foot mounted, shaft mounted, screw conveyor drives, and gearmotors. These drives may include spur, helical, herringbone, double helical, or bevel gearing in single or multistage arrangements as either parallel, concentric, or right angle configurations.

This standard revises, combines and supersedes two previous independent standards, ANSI/AGMA 6009-A00, Standard for Gearmotors, Shaft Mounted and Screw Conveyor Drives, and ANSI/AGMA 6010-F97, Standard for Spur, Helical, Herringbone and Bevel Enclosed Drives. The history of these standards have their roots in:
ANSI/AGMA 6013-A06 presents general guidelines and practices for design, rating and lubrication of parallel, concentric, and right angle shaft drives. It includes foot mounted, shaft mounted, screw conveyor drives, and gearmotors. It includes the available data, gear technology, and operational experience.
The comprehensive thermal rating procedure has been removed but is included by reference to AGMA ISO 14179-1.
This standard reflects the consolidation of “Enclosed Drives”, to include gearmotors, shaft mounted, and screw conveyor drives, into a single document.
The allowable stress numbers used in this standard are derived from ANSI/AGMA 2001-D04, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth and ANSI/AGMA 2003-C10, Rating the Pitting Resistance & Bending Strength of Generated Straight Bevel, Zerol Bevel, and Spiral Bevel Gear Teeth, and, along with other rating factors, provide a rating basis for enclosed gear reducers and increasers. The rating formulas are based on many years of experience in the design and application of enclosed gear drives for industrial use. Provisions are included in this standard for using stress cycle factors other than 1.0 to adjust the rating for extended or reduced life. Using a stress cycle adjustment factor does not guarantee a certain number of life hours or stress cycles, but is a method of approximating gear life under different load and speed conditions.
In addition to a general update to match current industry practices, substantial changes in the new ANSI/AGMA 6013-B16 include:
The competence to design enclosed gear drives, especially the knowledge and judgment required to properly evaluate the various rating factors, comes primarily from years of experience in designing, testing, manufacturing, and operating similar gear drives. The proper application of the general rating formulas for enclosed gear drives is best accomplished by those experienced in the field.
The first draft of ANSI/AGMA 6013-A06 was created in November 2000. It was approved by the AGMA membership in March 2006. It was approved as an American National Standard on April 25, 2006.
The first draft of ANSI/AGMA 6013-B16 was created in November 2011. It was approved by the AGMA membership in October 2015. It was approved as an American National Standard on April 5, 2016.
