2、ANSI/AGMA 6113-B16 Revision of ANSI/AGMA 6113-A06 Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the A

3、NSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effor

4、t be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing or using products, processes or procedures not conformin

5、g to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the nam

33、The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of ANSI/AGMA 6113-B16, Standard for Industrial Enclosed Gear Drives (Metric Edition). This standard revises, combines and supersedes two previous independe

34、nt 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: - AGMA 420.04, Practice for Enclosed Speed Reducers or In

35、creasers Using Spur, Helical, Herringbone and Spiral Bevel Gears - AGMA 460.05, Practice for Gearmotors Using Spur, Helical, Herringbone and Spiral Bevel Gears - AGMA 480.06, Practice for Spur, Helical and Herringbone Gear Shaft-Mounted Speed Reducers ANSI/AGMA 6113-A06 presents general guidelines a

36、nd 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 procedu

37、re 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 2

The competence to design enclosed gear drives, especi

39、ally 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.

44、d external load capacity. 4.1 Momentary load Gear drives designed and selected in accordance with this standard permit the following peak load conditions: - each peak shall not exceed 200% of the unit rating (at a service factor or application classification, KSF = 1.0); - a limited number of peak s

45、tress cycles, typically less than 104. AMERICAN NATIONAL STANDARD ANSI/AGMA 6113-B16 AGMA 2016 All rights reserved 4 For applications exceeding these conditions an appropriate service factor, or application classification, should be selected. WARNING: For momentary torques in excess of 200%, stall c

46、onditions, and low number of stress cycles the gear drive should be evaluated to confirm that these conditions do not exceed the yield strength of any component. Some applications may require selecting a gear drive with increased unit rating in order to accommodate adverse effects of environmental c

47、onditions, thermal capacity of the unit, external loading, or any combination of these. 4.2 Rating factors For calculating pitting resistance and bending strength rating for gears, specific values, or procedures for rating factors are given in Clause 6. Material properties, manufacturing considerati

48、ons, or experience may indicate that more, or less, conservative rating factors may be used. 4.3 System analysis This standard assumes that within the operating speed range, the system of connected rotating parts is compatible and free from critical speeds and torsional, or other types, of vibration

49、, no matter how induced. The gear drive designer or manufacturer is not responsible for the system analysis. 4.4 Considerations for cold temperature operation If units are to be operated in cold temperatures, generally below 0C, care should be taken to select materials and components that have adequate properties at the operating temperature. Consideration should be given to: - low temperature impact strength of materials; - fracture appearance transition or nil ductility temperature sp
